Definitions
- the invention relates generally to synthetic filament yarn fabric for use in the manufacture of an air bag and more particularly to mechanically compressed fabric structures which can be packed into small volumes without unduly affecting air permeability.
- Fabrics used for manufacturing air bags are required in general to possess a limited and controlled air permeability.
- such fabrics are generally woven structures formed from synthetic yarns made up of a plurality of individual filaments. Formation of such fabrics may be carried out on weaving machines using air-jet, water-jet or mechanical means for insertion of filling yarns between a plurality of warp yarns in a manner well known to those of skill in the art.
- Such woven textile materials are disclosed for example in U.S.
- One such known construction is a 420 denier nylon 6,6 fabric having 57 threads per inch in the warp and 53 threads per inch in the fill and sold under the trade designation MICROPERMTM by Milliken & Company in LaGrange, Georgia.
- a problem associated with this practice is once again the fact that the fabric produced may have relatively poor foldability due to the very high number of threads per inch within the woven construction which increases the stiffness and hence the packed volume requirement.
- Packed volume i.e. foldability
- good foldability is crucial if the air bag is to be accommodated in the steering wheel of motor vehicles in the least amount of space.
- good foldability also makes possible the trouble- free inflation of the air bag for protecting a vehicle occupant in the event of a collision.
- these issues of packing and trouble-free inflation become even more important as complex folding patterns are utilized to control initial impact in instances where an occupant may be directly facing the deploying cushion.
- the difficulty in improving foldability is that processes which are recognized to generally improve the drape of a fabric and thereby its foldability such as for example, physical, pneumatic or hydraulic impingement practices also tend to dramatically increase the air permeability of the fabric.
- U.S. Patent 5,508,073 to Krummheuer et al. (incorporated by reference) it has been proposed that improved foldability of air bag fabric can be achieved without sacrificing air permeability so long as yarns having very low filament linear densities are utilized in the construction.
- a woven fabric constructed substantially of synthetic yarn which has undergone processing by mechanical compression.
- the compressed fabric has a packed volume per unit area of fabric which is less than the packed volume per unit area of the fabric prior to mechanical compression.
- a woven fabric constructed substantially of synthetic yarn which has undergone processing such that the compressed fabric has a packed volume per unit area of fabric which is less than the packed volume per unit area of the fabric prior to processing.
- the dynamic air permeability of the fabric is reduced to a level below that of the fabric prior to processing.
- FIG. 1 is a cross-section view of a typical air bag installation mounted in a steering wheel of an automobile;
- FIG. 2 is a view illustrating the air bag of FIG. 1 , in expanded condition;
- FIG. 3 is a cross-sectional schematic view of a potentially preferred processing technique for the fabric according to the present invention.
- FIGS. 4A and 4B illustrate a folded construction for an air bag fabric useful in the testing of packed volume characteristics.
- FIG. 5 illustrates a device for measuring packed volume of the fabric according to the present invention
- FIG. 1 there is illustrated a schematic cross-sectional view of a typical driver's side air bag system 10.
- a typical system includes a folded inflatable air bag 12 disposed within a confined module 14 housed within the steering wheel 16 or dash panel if used for passenger side restraint.
- the air bag 12 is typically formed from a fabric 18 and is fixed to an inflater 20 which in turn is linked to a collision detection sensor (not shown).
- the collision detection sensor sends a signal to the inflator 20 thereby inducing a chemical reaction of a gas-generating agent to inflate the air bag 12 from the stowed position of Fig. 1 to the inflated position illustrated in Fig.
- the module 14 is disposed within the steering wheel, it is to be appreciated that the module may also be positioned in any other location opposing a vehicle occupant including the dash panel, door panel, or forward seat as may be desired.
- the material of construction for the air bag 12 typically includes at least a portion of woven fabric. Such fabric is generally woven from synthetic yarns which yarns are, in turn, formed from a plurality of filaments twisted together in known configurations. Filaments formed of polyester or nylon are generally preferred and filaments formed of nylon 6,6 may be most preferred.
- suitable linear densities for the yarn used in the fabric according to the present invention may range from about 40 denier to about 1200 denier while the denier of the individual filaments therein may range from between 1 denier to about 10 denier.
- the fabrics according to the present invention are preferably manufactured in a relatively tight construction, using either a plain or Panama weave. However, twill weaves may also be utilized if desired. By way of illustration only, and not limitation, some typical constructions for the fabric according to the present invention are set forth in Table I below.
- filament deniers of about 3 are believed to be representative of low denier per filament constructions while deniers of about 6, are believed to be representative of regular denier per filament constructions.
- the designation of threads per inch is in the state to which the fabric may be finished. That is, the thread density may be achieved either on the loom or through finishing (i.e. scouring and drying).
- these constructions are in no way intended to be limiting to the scope of the invention herein but are provided only as illustrative of air bag fabric types which may benefit from further processing to improve foldability (i.e. reduce packed volume characteristics) through further processing in accordance with the present invention.
- the fabric 18 made up of warp yarns 24 and fill yarns 26 is passed adjacent to and in intimate contact with a rubber belt 28 into a nip between a nip roll 30 and a heatable drum 32.
- the rubber belt is elongated due to the curvature around the nip roll and the force exerted by the drum.
- the fabric is preferably held between the belt and the drum for approximately 180° of revolution around the drum 32 so as to permit complete recoil.
- One potentially preferred piece of equipment for use in practicing such mechanical compression of the fabric 18 is believed to be available from Morrison Textile Machinery Corporation having a place of business at Fort Lawn, South Carolina. While the particular operating parameters utilized in practice of the process as illustrated in Fig. 3 may be varied in a manner as may be desired by those of skill in the art to achieve optimum results, in general, it is believed that in order to reduce the packed volume characteristics of the fabric 18 without unduly increasing the permeability thereof or otherwise degrading the fabric, the temperature of the drum 32 should be maintained between about room temperature and about 325°F. Lower temperatures of about 250°F or less may be preferred.
- the dynamic air permeability measurements for each of the fabrics is set forth in Table II below as is the packed volume measurements for such fabric for a fixed area of fabric both before and after processing.
- the fabric reference designations correspond to those set forth in Table I.
- the air permeability measurements set forth in Table II above are for dynamic air permeability which represents the performance of the fabric under instantaneous application of a differential pressure.
- dynamic testing is believed to provide a more realistic portrayal of fabric performance in an air bag during a collision event wherein the bag is inflated within a few milliseconds.
- the equipment is set at a particular differential pressure desired. The set pressure is then built up within a cylinder and exhausted quickly across the fabric.
- the measurement in millimeters per second represents the flow of a volume of gas (mm 3 ) through a given area of fabric (mm 2 ) within a short length of time (sec) upon application of a defined differential pressure drop across the fabric.
- FIGS. 4A, 4B and 5 The comparative evaluation of packed volume characteristics for treated and untreated fabric as set forth in Table II was carried out using a testing technique and apparatus substantially as illustrated in FIGS. 4A, 4B and 5. Specifically, two square fabric panels 34, 36 having a length of 28 inches on each side as illustrated in FIG. 4A were placed in overlying relation to one another so as to simulate the face and back of a simple air bag configuration, after which seams 37 were applied as shown. The seams were formed of 138 nylon thread at 8 - 12 stitches per inch. The resulting square double layered fabric configuration was then folded in a fan configuration along fold lines 38 on either side of the double layered fabric configuration to yield a substantially rectangular configuration with fan folds along either elongate boundary edge as shown in FIG. 4B.
- the layered fabric configuration was thereafter folded in a fan configuration along fold lines 40 at either end so as to yield a substantially square final folded configuration.
- the fabric structure folded in the manner described was placed in a test confinement chamber 42 having internal dimensions of 5 inches X 5 inches.
- a platen 44 machined to conform with the internal dimensions of the test confinement chamber 42 is thereafter lowered into the test confinement chamber attached to an Instron tester such as will be well known to those of skill in the art.
- the force applied by the platen 44 is monitored by a display 46.
- the volume occupied by the fabric within the test confinement chamber for any given applied force can thus be determined by simply monitoring the displacement of the platen 44 within the confinement chamber at such applied force.
- the packed volume of the pre-treatment fabric was in each case greater than the packed volume of the post-treatment fabric when measured under the same applied pressure.
- this beneficial result was achieved without substantially increasing air permeability of the fabric.
- the processed fabric according to the present invention is believed to provide the further benefit of reducing any variation in physical properties such as air permeability which may exist across the width of a woven fabric.
- These variations are generally understood to be due to different levels of residual stress induced during the weaving process. Such stresses may differ from yarn to yarn and machine to machine due to o slight differences in gripping mechanisms and yarn beat-up.
- Such residual stresses introduced during the weaving operation can be reduced by balancing the uneven yarn crimp as may exist across the fabric width. This may be achieved by subjecting the fabric to mechanical compression in accordance with the preferred practice of the present invention.
- the advantages of the fabric according to the present invention can thus be seen to result in a more compact air bag system which does not sacrifice air permeability thereby providing designers with additional flexibility in choices regarding the use of such systems.
- the air bag system comprises the air bag itself, the accommodation for the air bag in the vehicle, and the control o system for releasing the air bag function.
