Description

"Kit for upholstered furniture"

Description:

The invention relates to a kit for upholstered furniture according to the preamble of claim 1.

In a classic, conventional way, upholstered furniture is produced by first of all constructing a frame construction which has corresponding elements, and then upholstering this frame construction.

From the generic type DE 75 09 556 is a formed as a kit of several items substructure for a

Seating furniture is known in which two side parts are provided from plastic, for example, a construction foam. Wooden trusses extend between these two sides. Optionally, a back part made of plastic may be provided, for example, also from the construction foam. The plastic components of this seat are then upholstered in a manner known per se, for example with the aid of wadding pillows, and pull-through openings are provided on the elements consisting of construction foam in order to prevent the build-up of the seat. upholstery to enable this made of wooden cross members and plastic elements existing undercarriage.

In all the cases described above, the bases take up relatively much space. Therefore, a large area is needed in the factory, on softer the finished bases can be stored and also in the area of the actual upholstery cause the comparatively large bases a considerable amount of space. The po- sitive itself is a strenuous physical work that is all the harder the larger the surfaces to be padded. Another disadvantage is that the finished upholstered furniture require a lot of space, especially a large transport volume and accordingly high transport costs verur- things.

The invention has for its object to improve a generic kit to the effect that the production of upholstered furniture can be done by means of the kit as inexpensively and in the simplest possible way.

This object is achieved by a kit with the features of claim 1.

In other words, the invention does not suggest that

To design kit in the form that it contains components that are then joined together to an auxiliary construction of the upholstered furniture, for example, to a base. In the generic kit, the individual components can be referred to as blanks that correspond to a first, lowest processing level. In contrast, it is proposed to use prefabricated units, which in turn consist of several blanks and therefore represent a higher processing level. According to the proposal, the processing goes so far that the individual parts are designed according to the finished upholstered furniture: upholstered individual parts have the upholstery including the surface covering material of the finished upholstered furniture, unpadded individual parts have the varnished, veneered or other surface finish which they are to have in the finished furniture furniture.

According to the proposal, it is therefore intended to design the end product as a kit which has few ready-to-use individual parts and can be assembled from these individual parts outside of a furniture factory. By way of example only, the kit may include a fully upholstered seat, finished upholstered side panels, a fully upholstered backrest, and the at least one truss. With these ready-to-use parts, which correspond in their design to the finished furniture furniture, the upholstered furniture can be put together on site, for example in the showroom of a retailer or at the end customer, to the finished end product. As "ready to use" while the design of the items is referred to, for example, a suspension, a cushioning material and the textile or leather existing cover material comprises the padded items. The furniture feet can be advantageous already attached to such a prefabricated item, for example, on the traverse or on the side panels.

The ability to assemble the upholstered furniture from the prefabricated items, causes a modular structure of the upholstered furniture, so that different types of upholstered furniture can be created using less different items.

The proposed embodiment of the upholstered furniture offers a number of advantages, of which, for example, benefit the general public, that are transported by the disassembly of the upholstered furniture and the resulting smaller space more upholstered furniture per transport unit can, for. B. in a container or truck. As a result, the proportion of raw material consumption per upholstered furniture is ecologically advantageous reduced. In addition, there are the following advantages:

Advantages for the manufacturer:

■ A large variety of upholstered furniture can be produced without having to produce a correspondingly large number of different products. Rather, the production of less standardized elements is sufficient to enable the large variety of types of upholstered furniture.

■ This also affects aspects that are more related to the "management" of upholstered furniture: warehousing, spare parts, catalog production and the like are also made simpler and more economical by limiting them to just a few standardized elements.

^■ The individual elements of the upholstered furniture can be separately upholstered and covered so that the laborious work to be performed is limited to small units, which considerably simplifies the work for the staff.

^■ This creates improved working conditions and, where appropriate, enables higher productivity so that the production of upholstered furniture can be made more economical. ■ The individual elements of the upholstered furniture require less space in the manufacturing plant and can therefore be stored particularly economically, be it in the interim storage of prepared racks, which still need to be padded, or if it is the intermediate storage of ready-padded elements before their transport to the customer.

Advantages for the dealer:

^■ Corner seat groups with two legs of different lengths can be reconfigured. So, as shown in the exhibition, the furniture does not need to be installed at the customer: One or both legs can be made longer or shorter, or the corner design can be reversed symmetrically.

■ The furniture can, disassembled into individual parts, easily through such narrow staircases, angled hallways or narrow

Room doors are transported through which the furniture would not fit.

^■ Disassembly creates single, small, lightweight units. The transport of the upholstered furniture into the transport vehicle and from the transport vehicle to the customer becomes easier and in the literal sense also easier.

Advantages for the customer:

^■ It can be an arbitrarily long and possibly extending around several corners total furniture can be created, for example, large reception, waiting or exhibition halls, without an expensive custom-made would be required.

^■ Rather, the poster furniture is simply composed of standardized, commercially available components and can therefore be quickly delivered.

^■ The user can reconfigure the upholstered furniture, for example when moving or remodeling the apartment / room. For example, the aspect ratio of legs of different lengths of an angular seating group can be reversed. From single furniture can be made a larger seating area. A multi-seat seating group can be divided into several individual pieces of furniture and, if appropriate, individual seats, it being possible if necessary to purchase additional side pieces.

According to the proposal, the actual upholstery work is not carried out on the entire underframe, which is as large as the finished upholstered furniture, but on smaller items: Thus, it can be provided as a single item a single seat surface or to produce a single so-called seat angle comprising the backrest and seat, and to cushion these items to completion.

Also a side part represents an item of a proposal

Kit part. As a side part in the sense of the present proposal, an element is understood, which is followed by the traverse. It may be an element which protrudes higher than the seat so that it forms, for example, an armrest of the upholstered furniture. In particular, such high side parts could also be padded or unpadded.

However, a side part can also be designed to be less high than the seat, so that it is for example one side of the

Upholstered furniture completes and supports without forming an armrest, similar to the case of an ottoman, for example.

In addition, such a less high side part between the two lateral ends of the upholstered furniture may be provided supportive, for example, in a particularly wide furniture such as a multi-seat sofa. In this case, joists on both sides of the side panel.

Side parts can advantageously have the furniture feet of the upholstered furniture.

According to the proposal, the seat or the seat angle is designed as a self-stable construction, so unlike only a cushion contains all the components that are provided as part of the upholstered furniture for the strength and dimensional stability of the seat and the backrest; For example, frame members made of wood, metal or plastic and optionally also suspension elements, which may be provided for example in the form of a wave suspension. This one Stable component can be handled fully padded due to its inherent stability and dimensional stability. Hereinafter, a seat angle is mentioned regularly in the further description, since it represents an advantageous embodiment of the kit, but instead only one seat can be provided - if, for example, no sofa but a couch is to be created - or the use can be made more separate Individual parts for the seat and the backrest be provided.

The side parts have - depending on the design of the furniture and possibly in a simplified perspective - an approximately cuboid shape, so that they can be arranged and transported to save space. Several seat angles can also be arranged to save space, for example by interlocking, so that compared to the transport volume of several complete upholstered furniture, the transport volume of proposed kits is significantly reduced and, accordingly, the unit cost-related transport costs for the upholstered furniture can be kept optimally low.

The traverse can also be transported to save space as an elongated element.

To erect the upholstered furniture, the two side panels are connected to the crossmember, the crossmember not only ensures the cohesion of the two side panels, but also forms the support for the seat angle, so that acting on the seat angle forces passed through the cross member in the side panels and then can be removed into the soil.

If necessary, the furniture feet can be arranged on the traverse, so that the forces on the traverse and the furniture feet can be removed directly into the ground.

Advantageously, the traverse as described above as a separate

Component present, which is independent of the seat angles and the side parts is transported. This allows an optimally space-saving arrangement of the individual components of the kit during transport, ensure a particularly good use of space of the transport volume, and achieve the lowest possible weight of the items to be handled. Alternatively, however, it may be provided that the traverse is firmly connected to the padded seat of the seat angle and forms a jointly manageable assembly with the seat angle. In this way, the number of components to be handled of the kit for those who created the upholstered furniture from the kit, so that in this case, only the seat angle including traverse as the first module and the two individual side panels must be connected as a second and third module together to make out of the kit the upholstered furniture.

Advantageously, the individual components or assemblies of the kit can be releasably connected to each other. In this way, for example, furniture can be built up in an exhibition space and then dismantled for transport to the end user, so that space-saving transport is made possible. In addition, due to the design as a kit by replacing individual components or assemblies, the furniture can be redesigned and adapted to changing to-sayings of the user.

Alternatively, it can be advantageously provided that the assemblies to be joined together can be permanently connected to each other. For example, when using tear-off screws, the tearing off of the screw head can indicate that the desired strength of the connection and thus the desired stability of the furniture have been achieved. When using snap or snap connections it is also ensured that the initially produced compound can not be solved undesirable. For example, it may be advantageous to provide a non-detachable connection of the components or assemblies with the aid of latching connections. By means of this connection technique, a tool-free installation of the upholstered furniture is possible, so that a particularly quick and uncomplicated and possibly also layman-feasible installation is made possible.

It has already been mentioned that the side parts can either project so high that they form armrests of the upholstered furniture or that they are designed so low that they contribute between the two lateral ends of the upholstered furniture to its support. Regardless of the overall height can be advantageously provided that the side parts have receptacles on both sides for the connection of a traverse. In this way, an arbitrarily long juxtaposition of seat angles can be made possible with such side parts designed. Any length or wide upholstered furniture can thus be produced without the need for special independent furniture, not even correspondingly long trusses are required.

Advantageously, the Traverse can be configured from all possible Trägermaterialaien and forms. In this way, the production of very dimensionally stable and rigid bending trusses is inexpensive, without the need for special mold costs, as would otherwise be the case if the trusses were configured for example as extruded profiles. The design of the traverse made of metal offers, for example, the use of wood, the possibility of achieving high strength with the lowest possible weight of the traverse and in particular due to the strength of the material to allow a stable connection of the traverse to the respective side part, especially in a relatively small space to allow such a stable connection. It is also possible to set up and dismantle the system as often as desired, while at the same time achieving a slight height adjustment.

Such a connection to a side part, for example, take place in that a connection plate is provided on the side part, which allows a positive support of the traverse, so that the traverse so rests on this terminal plate. The connection plate itself can advantageously be transported separately from the side part, so that several

Side parts can be transported close to each other fitting and be provided only at the installation of the furniture with the connection plates.

The connecting plate may, for example, have a pin on which the traverse can be plugged, which is designed for this purpose at least in the region of its adjacent to the side part of the end as a hollow profile.

Alternatively, it can be provided that the connection plate has a pin which has a shell-like cross section, so that in this shell-like cross section, the cross member can be inserted, wherein the shell-like cross-section is adapted to the geometry of the traverse such that a compound, for example in shape a screw connection,

Locking o. The like. Can be created and the traverse is not just simply loose in this cup-shaped pin.

Alternatively, conversely, it may be provided that the connection plate has a recess into which a projection of the traverse can be inserted. The recess may be provided, for example in the form of a slot, wherein the traverse end has a hook, with which it can be hooked into the slot of the connection plate. In this case, ie without protruding pin, the connection plate can be made so flat that it does not obstruct One can project the overhanging parts of the kit that were being transported. Accordingly, the connection plate does not have to be transported separately from the side part, but already at the factory, the side parts can be provided with the connection plates and transported, so that the

Number in the construction of the upholstered furniture to be mounted items can be kept advantageously low.

In such a flat configuration of the connection plate can be provided, for example, to screw the Traverse with the connection plate. In this case, the connection plate has recesses into which the screws extend. For such a screw connection, the traverse can advantageously have one or more angled laminations at its end, which rest against the connection plate and through which the screws extend.

To improve the stability, in the above-mentioned embodiment, the cross-member may be provided such that it has a reinforcing element at its end, which likewise forms an angled tab and thus reinforces the cross-member in the region in which it adjoins the connecting plate.

Advantageously, it can be provided in another embodiment of the truss connection, that the connection plate, although a pin, but this is designed as a hollow profile, in which the traverse can be introduced.

In the embodiment of the traverse can be provided that it has at least one boom, which extends transversely to the cross-member longitudinal direction and also serves to support the seat angle, so that it is stored non-tilting. In this way, by means of only a single traverse, a particularly lightweight embodiment of the upholstered furniture and the bean Spruchung of particularly little transport space for transporting the kit achievable.

Alternatively, it can be provided likewise to provide only a single traverse, but to provide it with such a depth that a tilt-proof support of the seat angle is thereby ensured. Due to this particularly wide embodiment of the traverse, this can also have a particularly high deflection stiffness and also the number of components to be handled compared to the use of two or more trusses is reduced.

However, if two trusses are provided or more, so the handling of the smallest possible individual components is supported. These two trusses are preferably arranged at such a great distance from each other that they allow the most stable and tilt-safe storage of Sitzwinkeins. If the seat angle has a flat bottom, the two trusses can preferably be arranged horizontally in the same plane, so that a horizontal bearing plane is created for the seat angle. However, the arrangement of the trusses may have a height offset, for example, if the underside of the seat angle has such a height offset.

In particular, it may be advantageously provided to arrange a rear cross member higher than a front cross member, so that in this way a particularly non-tilting support a seat angle is effected, especially when horizontal forces act against the backrest.

Advantageously, the seat angle may have on its underside a recess in which the traverse is at least partially received. In this way, a high and thus particularly resistant to bending traverse can be used and yet the compliance with a desired, possibly possible As low as possible seat height can be made possible by the traverse quasi immersed in the seat angle.

Advantageously, at least two juxtaposed seat angle can be provided. It has already been mentioned above that the upholstered furniture can be configured by a juxtaposition of several seat angle to almost any width. But even with comparatively small widths can be provided to use two or more seat angle. In this way, the units to be padded are kept very small and thus facilitates the work for the upholsterer in particular. Thus, for example, be provided for a two- or three-seater sofa, accordingly to use two or three seat angle. For the furniture manufacturer, this means that with a comparatively low

Number of standardized elements a wide variety of different furniture can be created by, for example, different lengths of trusses are used, but basically the same side panels and adapted to the desired width of the furniture and to the respective truss length number of individual seat angle.

In order to keep the work for the upholsterer as simple as possible, to keep the weight of the seat to be handled as low as possible and to optimally utilize a given transport space, it can be provided, for example, that the seat angle has a width of at most 120 cm. Thus, for example, it can be provided within the framework of a modular construction-type concept that seat angles with widths of approximately 70, approximately 95 and approximately 110 cm are provided, so that the combination of such seat angles can be used to individually adapt the most varied furniture lengths from the individual armchair to to longer seating landscapes.

Advantageously, it can be provided that the traverse over its entire length a consistently the same cross-sectional profile having. This is the case, for example, if a extruded profile of metal is used as traverse, but it can also be advantageously provided with folded sheets that it has a continuously the same cross-sectional profile over the entire length. In this way, it can namely be provided to shorten the traverse arbitrarily and always ensure an embodiment of the traverse at its two ends, which allows a connection to a side part. If necessary, only holes are provided which allow a connection, for example, to receive screws or locking elements. If necessary, however, it may also be provided to provide the crossbar as standard with a regular perforation, which is adapted to the desired grid dimension of the modular concept, so that the crossbar material can be arbitrarily shortened within this grid and always allows attachment without side parts , since the holes required for this are already present in the truss material from the outset.

Advantageously, a side part can be provided a plurality of fastening elements, which serve to fix the traverse and are provided at different heights. For example, recesses for receiving the fastening screws can be provided at different heights on a connecting plate. Due to the height variability of the seat, the dealer can perform on the same furniture by height adjustment of the traverse the same furniture with a larger and a lower seat height, instead of providing two or more furniture with different seat height. Or he can demonstrate both variants in the showroom and sell the furniture with one seat height, even if a piece of furniture with the other seat height is ordered, because when the furniture is set up at the customer, the seat height is selected and the crosshead mounted correspondingly high becomes. The customer can in particular even after prolonged use of the upholstered furniture, if have formed certain everyday habits, adjust the seat height to his needs.

The connection of the traverse to a side part can advantageously be done by means of a screw: a tool-free

Connection such as a jamming of both components by means of a wedge-shaped geometry would be stable and would be under load more and more solid, but would later poorly disassembled. A looser connection, on the other hand, would later be easy to disassemble, but may not be stable enough during use. A typical load case may be, for example, that the upholstered furniture is designed as a sofa, a user lies on the upholstered furniture, his legs stretched while pressing his feet against the side part. A stable connection between traverse and side part is therefore desirable.

The proposal according to a traverse is provided, this can be used to advantage, the upholstered furniture additional

To give functions:

The traverse, for example, form a cable channel, for example, to record AC power, speaker or data lines. For this purpose, the traverse has an insertion opening for the cable and at a distance therefrom an opening for the cable. In order to securely hold the cable within the cable channel, the cross member also has at least one retaining element. In the simplest case, the traverse can be designed as an open-topped profile with an approximately U-shaped cross-section, so that the upper, continuous opening allows insertion and removal of the cable and the profile closed at the bottom ensures the retention of the cable. For example, a holder may be provided on the traverse, which protrudes beyond the seating surface, for example projecting forward, so that it can carry a shelf there, for example in the form of a horizontal table surface, or a sloping desk surface, or a basket, bag or the like container. If the holder protrudes to the rear over the seat, he may, for example, carry a lighting device, such as a reading lamp, or he may, for example, speakers of a home cinema speaker system wear.

Alternatively it can be provided to provide speakers in a padded items of the kit, for example in a backrest or a side panel.

Advantageously, it can be provided to provide a lower suspension of the seat on the crossmember. In this way, a considerable weight saving of the individual parts to be handled and a significantly more economical production of the individual parts can be made possible: the one or more traverses are already designed as stable components. You can, for example, form a frame that receives the springs of the spring base and in particular to absorb the spring tension is able. Accordingly, the frame of the seat angle can be designed much weaker, for example, plates of thinner wood material than if this frame would have to absorb the springs and the corresponding spring forces. The seat angle can be made lighter in this way, while the crossbar must be made only slightly heavier, so that the total weight of the upholstered furniture can be reduced and the weights of the items to be handled by the transport personnel can be kept as low as possible.

Advantageously, the embodiment of a side part may be provided as a corner element, that is, as a side part, to which of Connect trusses to both sides, with the trusses aligned at an angle to each other, for example at a 90 ° angle. Such, designed as a corner element side part is carried out advantageously padded and has its own seat, so that a group of seats with through, in

Angle running sitting or lying surface can be created.

In the drawings, a total of 1 seating furniture referred to, which has two side parts 2, 3, by traverses

4, 5 are interconnected. The trusses 4, 5 are detachably attached to the side parts 2, 3. In the embodiment of FIGS. 1-10, the trusses 4 and 5 have an upright oriented rectangular cross section. The top of the trusses 4, 5 is aligned at the same height, so that they form a horizontal plane as a support for a seat angle 8. However, if the seat angle is suitably configured, a height offset of the two trusses 4, 5 can also be provided in order to ensure a horizontal alignment of the seat surface of the seat arch 8. A seat angle 8 is shown in Fig. 1, which makes up about half the length of a traverse 4 or 5, that is substantially half the width between the two side parts 2, 3 fills.

The seat angle 8 has, as is apparent in particular from FIGS. 10, 18 and 19, on both sides in each case via a side cheek 9 and 10, which are designed substantially L-shaped. These side cheeks 9 and 10 are part of a frame, which represents a strength-giving frame of the seat angle 8. In the embodiment of FIGS. 1-10 it is provided that the

Side cheeks 9 and 10 are interconnected by a plurality of profiles, for example, by a provided rear wall 11 and by front and rear connection profiles 12 and 13, which are flush with the trusses 4 and 5, in particular with the bottom 7 of the trusses 4 and 5 ,

The side cheeks 9 and 10 each have recesses 14 and 15 on the underside, which correspond to the cross section of the trusses 4 and 5. As a result, a smooth, flush bottom-side conclusion of the seat angle 8 in conjunction with the connection profiles 12 and 13 is given. In addition, the recesses 14 and 15 prevent a displacement of the seat angle 8 transverse to the trusses 4 and 5.

Between the two side parts, which are marked in FIGS. 2-4 with 18 and 19, two trusses 20 and 21 are detachably fixed. On the two trusses 20 and 21 two seat angle 8 are placed in an armchair shape, each having two interconnected side walls 9 and 10.

The side cheeks 9 and 10 of the embodiments shown in FIGS. 2-4 are each provided on the underside with recesses 14 and 15, which correspond to the cross section of the trusses 4 and 5. Between such recesses 14 and 15 of the side cheeks 9 and 10 are, as is apparent in particular from FIG. 4, flat profiles 31 - 34 arranged, the ge Together with other end profiles 35 - 38 achieve a bottom-level finish in the furniture 1. In addition, the flat sections 31 - 34 can reinforce the trusses 4 and 5 also in the sense of a transverse bracing. Another possibility of a transverse bracing is based on

Fig. 5 and the traverses 4 and 5 shown there explained. There are a total of four support rods 42 - 45 shown, which extend transversely to the trusses 4 and 5, are connected to the trusses 4 and 5 and thus cause a transverse stiffening of the trusses 4 and 5. Preferably, the connection between the support rods 42 and 45 and the trusses 4 and 5 can be made detachable, so that the arrangement shown in Fig. 5 can be easily disassembled.

But it is also possible, without cross-connection between the

Traverses work because the stability of the seat angle is achievable.

Fig. 5 also shows brackets 46-49, by means of which the trusses 4 and 5 can be fixed to the side parts 9 and 10. Each holder has, as shown in particular in FIGS. 7 to 9, a connection plate 51, which has apertures 52, by means of which the connection plate 51 can be screwed to a side part 9 or 10. The side parts 9 and 10 are designed to reliably fix the brackets 46 - 49 accordingly stable or have corresponding reinforcements.

From the surface of the terminal plate 21, a pin 53 extends with an L-shaped cross section. This pin can in the

Rectangle hollow profile of the trusses 4 and 5 are inserted or the trusses 4 and 5 can be plugged onto the pin 53, which, connected by means of the connection plate 51, is located on a side part 9 and 10 respectively. A reliable connection between the pin 53 and the trusses 4 and 5 is ensured by a screw. For this purpose, the trusses 4 and 5 holes 54 and the pins 53 have corresponding holes 55, wherein the holes 54 and 55 are aligned with each other when the trusses 4 and 5 are attached to the pins 53.

11 shows a traverse 4 which, in contrast to the two traverses 4 and 5 of the drawings 1-10, has a particularly large depth. It can therefore also be referred to as a center traverse, since only a single such center crossbar is sufficient to accommodate the seat angle 8 reliable.

The corresponding holder 46 likewise shown in FIG. 11 has a correspondingly adapted cross-section of the pin

53, so that in this case the traverse 4 can be inserted into the trough-shaped cross-section of the pin 53. Again, openings 55 are provided on the pin 53, which cooperate with corresponding openings 54 of the cross member 4 to allow a screw connection.

FIG. 12 shows a further embodiment of a traverse 4, similar to that of FIG. 11, wherein here too the traverse 4 has such a great depth that it can be used as the only or as so-called center traverse and a sufficiently large support surface for the Seating angle 8 provides to ensure its tilt-free storage. The trusses of the embodiments of FIGS. 11 and 12 are designed as sheet metal edged parts and thus inexpensive to produce because they do not require their own tools, as it is necessary for the production of an extruded profile. They can be processed to a closed hollow profile by being welded together at a corresponding longitudinal seam.

While in the embodiment of FIG. 11 was provided, the traverse 4 end by appropriate completion To close plates, can be provided in the cross member 4 shown in FIG. 12 that this is indeed closed circumferentially, that forms a hollow profile, but the end is open. In this way, an invisible receiving the pin 53 is possible, while inserting the cross member 4 in the pin 53 of the

Fig. 11, the pin 53 remains visible from the outside. If, however, the side cheeks 9 and 10 of the seat angle 8 recesses 14 and 15, as well as an invisible connection between the cross member 4 and pin 53 can be made possible by the seat angle 8 that extends correspondingly deep below the top of the cross member 4 down.

On the upper side of the traverse 4 in the embodiment of FIG. 12, a plurality of holes are provided, through which a firm connection with the seat angle 8 can be made so that it is reliably secured against lifting forces or tilting movements.

FIG. 13 shows an exemplary embodiment of a traverse 4, in which the crossbeam is configured substantially as a round profile, for example as a pipe section. At this tube of the crossbar 4 side connection plates 51 are welded, so that here no additional support is required as a separate component. Instead, the traverse 4 with its connection plates 51 can be connected directly to the side parts 2 and 3.

Furthermore, four extension arms 56 are provided on the tube of the traverse 4, which extend laterally from the tube, that is to the front and to the rear, based on the orientation of the seat 1, so that the traverse 4 shown in FIG. 13 by means of the boom 56 a seat angle can set a large depth and can support accordingly stable against tilting, so that with appropriate dimensioning and the cross member 4 of FIG. 13 can be used as a single or middle traverse. Alternatively, smaller sized such trusses may be used. Find if two such trusses are arranged over the depth of the furniture in a row.

In Fig. 13a, a connection technique is shown in which a trained example as a C-rail traverse 4 is used. At the end portions of the cross member 4 plates 51a are attached, which are designed as screwed or latching plates. At the arm or side panel or intermediate part of the piece of furniture can be factory-mounted a mounting plate which forms the counterpart for the plate 51 a, wherein the cross member 4 below

Interlocking these two plates screwed, plugged or dismantled in any other way and can be mounted stably.

A side part 2 is shown, from which a cross-member 4 extends, which is provided as a center cross-member, so as the only provided Traverse for supporting a seat angle 8. The corresponding second side part 3 is not yet mounted and, accordingly, not shown in FIG. 14, likewise a second one

Seat angle 8, for the recording of the traverse 4 is provided, also not shown. However, it is apparent from this embodiment, that the seat angle at the front and / or on the back of the chair 1 can extend deeper than up to the top of the cross member 4 down, so that the cross member 4 is housed visually inconspicuous and usually not is visible.

Fig. 15 shows a further embodiment of a traverse 4, which extends almost like the embodiment of Fig. 14 almost over the entire depth of the seat or at least the side part 2. As in the embodiment of FIG. 14, in the embodiment of FIG. 15, the traverse 4 z. B. be designed as a folded sheet steel element and, in order to design a closed hollow profile and to have the highest possible bending stiffness, to a longitudinal seam be welded to a closed cross-section. In particular, the plurality of beads in the cross member 4 of FIG. 15 cause a particularly high rigidity in this traverse. 4

FIGS. 16-18 show components of a seat 1, namely, in FIG. 16, a traverse 4 which, in contrast to the exemplary embodiments of FIGS. 11-13, does not become wider at the top, but downwards. This Traverse 4 is z. B. designed as a sheet metal part and particularly inexpensive to produce, since it has not been closed to a hollow profile. The associated side cheek 9 of a seat angle 8 is shown in Fig. 18. It has two lower-side recesses 14 and 15, which are adapted to the cross-sectional geometry of the cross member 4 and also expand downwards.

Fig. 17 shows the associated connection plate 51 with the openings 52, which serve for screwing with a side part 2 or 3 and with a pin 53, which is also adapted to the cross-sectional geometry of the cross member 4 and on the cross member 4 can be plugged.

Fig. 19 shows a seat angle 8. The side parts 2 and 3 form the part of a frame. They may for example consist of a wood material and be connected to each other by wooden strips 57. The seat surface of the seat angle 8 is provided with a so-called wave suspension 58, while in the region of the backrest of the seat angle 8 a plurality of horizontally tensioned rubber-elastic straps 59 are provided. On this frame then the actual upholstery has been padded, which is designated in Fig. 19 with 60. This padding is in turn covered with a cover.

20 shows a chair 1, in which the two side parts 2 and 3 are aligned at right angles to each other, as well as the two seat angle 8. The connection of the two seat angle 8 via a corner part 61, which thus has a special Ausge staltung a seat angle represents 8, namely a seat angle, the backrest is bent and describes a 90 ° angle.

Fig. 21 shows the associated substructure: The two side parts 2 and 3 are shown here as well as in Fig. 20, since they are on the one hand (Fig. 20) padded and represent the armrests of the chair 1, as they also on the other hand (Fig. 21) serve as part of the substructure of the chair 1. Two transverse members 4 and 5 each extend from both side parts 2 and 3 to a corner support 62, which has two curved cross members 64 and 65, which are connected to two narrow side members 63 which are not visible in the later seating furniture 1. These special side parts 63 do not extend higher than the seat surface of the seat angle 8, while the visible side parts 2 and 3 accordingly extend significantly higher than the seat surface of the seat angle 8, so as to form in each case an armrest of the seat 1. The opposite _. lower special side parts 63, on the other hand, serve purely functionally to fix the traverses 64 and 65 and to support the corner part 61.

Notwithstanding the illustrated embodiment of FIGS. 20 and 21 may be provided to provide such low side portions 63, even if the arrangement of the seat angle 8 in a chair 1 should not be done over corner. Also, to create a particularly long piece of furniture can be provided for this purpose not to use special, particularly long trusses, but rather to use the standardized trusses 4 and 5 and to design the side parts such that they similar to the side parts 63 connecting two trusses allow on both sides of the side parts, so that a seat of any length can be created in this way. Fig. 22 is a traverse 4 is shown, which consists of a folded sheet metal profile. At its front end, the traverse 4 has three angled lugs 75, each having at least one through-bore 76 for receiving fastening screws. Fig. 23 shows the cross member 4 in front of a connecting plate 51. This can be screwed by means of their openings 52 with a side part 2 or 3 and in turn has recesses 77 which serve to fix the cross member 4 to the connection plate 51. For example, the recesses 77 may have an internal thread, so that the cross-member 4 can be screwed directly onto the connection plate 51. Alternatively, the recesses 77 may be configured as through holes, so that the fastening screws of the cross member 4 can cooperate with nuts, which are provided behind the connection plate 51 and are welded, for example, to the connection plate 51.

FIGS. 24 and 25 show a situation similar to FIGS. 22 and 23, but with the traverse 4 provided with a reinforcing element 78 in its end region. The reinforcing element 78 is designed as a presigünstiges Blechkantteil and also has angled tabs, so that a particularly stable connection of the cross member 4 is effected to the connection plate 51. The angled tabs of the reinforcing element 78 are designated 79 and have through holes, which are aligned with the through holes 76.
