My invention aims to provide improve ments in fastening means particularly, though not exclusively adapted for use in connection with upholstery installations. n

This application is a division of my prior application, Serial No. 207 ,413, filed July 21, 192

preferred frame;

Fig. 3* is an elevation of a portion of the panel, the upholstered covering being removed to expose a fastener unit and show the means which attach theunit to the panel;

Fig. 4 includes a side and a plan view of my stud unit for securing an upholstered panel to a frame; and

Fig. 5 is a section showing portions of a frame and upholstered panel with a slightly modified form of fastener unit securing the upholstered panel to the frame.

Referring to the drawings, I have illustrated an upholstery installation and means for securing the same2 particularly though not exclusively, useful 1n connection with vehicle body construction. For the purpose of illustration only, I have shown my improved installation and means for securing the same in connection with securing an upholstered panel to the frame of a sheet metal door of a vehicle body.,

The upholstered panel may be of any suitable construction, but I have shown one which includes a relatively thin backing of cardboard 1, or the like, overlain by a padding 2, and an u holstery fabric 3 covering the adding andpwrapped over the edges of the hacking where it is secured in any suitable 45 manner to the opposite face thereof. To the fastening the upholstered panel to the door I" upholstered panel, I have secured fastening units each of which comprises a casing part 4 and a stud part 5, as best shown in Fig. 2. The stud gart projects outwardly beyond that face of t e upholstered backing which is not covered by the upholstery 3 and is adapted to engagea stud-receiving aperture 6 provided in the bottom of a recessed por-` tion 6 of the frame part 7 (Fig. 2). The fastener unit, which I have illustrated in Figs. 1 through 4, includes the casin part 4 pressed from sheet metal and provided with a tubular portion 8 from one end of which extends inwardly a flange 9 terminating about an aperture 10.

Attaching means are provided at both ends of the tubular portion 8 of the casing part 4 for securing the fastener unit to a support. These attaching means are in the form of fingers 11 and 13 illustrated in Fi s. 3 and 4. The attaching fingers 11 normal extend laterally outwardly from that en of the tubular portion 8 at which the flange 9 is connected and are adapted to engage one face of the backing when the tubular portion is inserted intoa pre-formed aperture in the backing. The attaching fingers 13 are located at the opposite end of the tubular portion 8 and normally extend therefrom in parallel relation with the wall of the tubular portion 8, as shown in Fig. 4. Other ngers 12 are provided at the same end of the tubular portion 8 as the fingers 13 to provide means for assisting in holding the stud part 5 in assembled relation with the casing art 4, as will be hereinafter more full descri d. The tubular portion 8 is located tween the attaching portions or fingers 11 and 12 for a purpose more fully hereinafter described. The stud part 5 is provided with a relatively thin flat base portion 14 (Fig. 2) lfrom which extends a shank portion 15 havlng a head 16 at its outer end and provided with a neck 17. This stud member 5 is assembled with the attaching part Aia the manner indicated 9 in 2 and 3, the base bein located within the tubular portion 8 and eld in assembly therewith by the flange 9 and fingers 12,

`10 (Fig.`2) thereby permitting lateral shiftin of the' stud in any transverse direction reitive to the attaching part.

In securin the fastener unit to the upholstered bac ing, I first rovide an aperture in the backing and padding of substantially the same diameter as the outside diameter of the tubular ortion 8 of the casing part and then insert tlie tubular portion into the aperture so that the fingers-11 may rest against the backing at its inner face, as shown in dotted lines in Fig. 3, to prevent passage of the casing part entirely through the backing. The lingers 13 which normally extend parallel with the tubular portion 8, as indicated in Fi 4, are then bent outwardly and downward y against the padding, as indicated in Fi 3 t ereby positively `securing the attacin unit in position relative to the backing. fter all of the fastener units are secured to the backing in the manner above described, the upholstered fabric 3 may be stretched over the face thereof and secured in any suitable manner to conceal the fastener units at one side.

In practice, the stud-receiving apertures 17 are usually made prior to forming the door frame, therefore, when the frame has been completely formed, manufacturing tolerances must be considered. To compensate for slight variations, I have found that, by

rmitting lateral shifting of the stud memlir in any direction, they may be aligned with the stud-receiving apertures very readily and the upholstered part may be easily secured in place.

Heretofore fastener units have been atl tached to the upholstered backing in such a manner that the attaching part, or casing, was located at either one side or the other of the backing, thereby adding to the thickness of the entire installation. I have found that this extra thickness is in many instances undesirable, therefore, I have reduced to a minimum the thickne of the upholstered backing by securing the casing part, of the stud unit above described, between the faces of the backin (the backing including the padding as in icated in Fig. 2). When the units are secured to the backing, as illustrated by the drawings, the attachinlfingers 11 and 13 lie substantially Hush wi the faces of the backing (Fig. 5), and, therefore, there are no proJecting portions at either Aface except the stud part itself.

In some instances, the attaching part or casing of the fastener unit is attached to a backing which comprises only a relatively stii material, such as cardboard, and is confined between the faces thereof. Such would be the case if the padding 2 and cardboard 1 (Fig. 2) are considered as being of a single thickness or several thicknesses of cardboard. In either instance, the padding 2 may be placed in position to cover one'entire face of the backing and fastener units. As there are no protuberanccs caused by the stud units when attached to a backin in any of the Ways above described, the pa ding will lie erfectly flat and a smooth thin finish Wil be rovided when the upholstery fabric 3 has een applied.

It is my intention to have it clearly understood that in my invention, as set forth by the appended claims, the use of the term backing is broad as to its meaning and includes the structures above described. The

invention is not to be construed in any way as being limited to the material or materials used in the construction of the backing.

In Fig. 5, I have shown an installation in which the stud member is provided with a relatively wide neck 19 so that the upholstered backing may be attached to frames formed of various thicknesses of material without making the depressed portion shown in Fig. 2. In this instance, the head of the stud 1s shown as projectin beyond the inner face of the frame part g, thereby clearly showing that accommodation is made for greater thicknesses of material and the neck 19 of the stud is shown as gripping the wall surrounding the stud-receiving aperture to hold the upholstered installation tightly lagainst. the frame part 7.

While I have shown and described preferred embodiments of my invention, it should be understood that I do not wish to be limited thereto, my invention being best described in the following claims.
