Definitions

  • the present invention relates generally to an air bag assembly and more particularly, to an air bag having a generally toroidal configuration constructed from a section of tubular material.
  • a gas cushion impact protection device is generally provided with an inflatable gas bag which is integrated into the body portion of a vehicle against which a passenger may be thrown during a collision event.
  • a sensor detects deceleration values in a vehicle indicative of a collision
  • a trigger signal for a fuse in a propellant charge forming part of a gas generator is produced.
  • the gas bag is then inflated within a few milliseconds by gases generated by the gas generator.
  • Gas bags housed within the steering columns of vehicles typically are formed of two disk-shaped pieces of material joined together at their periphery wherein an opening is disposed within one of the disk-shaped pieces of material for introduction of the inflation media.
  • Gas bags for use in opposition to passengers within a vehicle are generally composed of a multiplicity of relatively complex shaped material pieces joined together so as to produce a bag having a profile suitable for disposition between a vehicle occupant and a dash panel or other structure from which the gas bag extends during deployment.
  • gas bags Prior to the present invention, gas bags have typically been characterized by relatively complex seaming structures by which the various components of the bags are joined together. Such seams generally add undesirable complexity to the bags.
  • the present invention provides a gas bag configuration formed of a tubular construction minimizing the use of load-bearing stitching previously needed.
  • the present invention thereby provides a useful advancement over the state of the art.
  • Figure 1-a is a cross sectional view showing a packed toroidal air bag according to the present invention.
  • Fig. l-b is a cross sectional view showing the inflated bag, and illustrating the primary area used for venting and impact.
  • Fig. 2 is an exploded view the several rings used in one embodiment of the invention for attachment of the air bag to an inflator.
  • Fig. 3 shows the sectioned end of the fabric tube with stitching as used in one embodiment of the invention.
  • Fig. 4 shows the stitched end of Fig. 3 gathered to approximately the diametral size of the mooring ring.
  • Fig. 5 shows the parts to be assembled during mounting of one embodiment of the air bag of the present invention to an inflator.
  • Fig. 6 is the completed assembly of the components in Fig. 5.
  • Fig. 7 shows a section of the tubular fabric containing sections with greater pick spacing for venting.
  • Figs. 8(a) - 8(e) show various means of mooring the sectioned end of the fabric tube, wherein Fig. 8(a) shows a tapered band which when tensioned by the fabric moves up a mating taper on the mooring ring, thereby clamping down on the fabric.
  • Fig. 8(b) illustrate a band which may employ a resilient strip to protect the fabric from cutting.
  • Fig. 8(c) shows the same configuration as 8(b) with the fabric mounted in the opposite sense to the stop.
  • Fig. 9(d) shows the fabric compressed by the band against O-rings located in grooves in the mooring ring.
  • Fig 8(e) shows the fabric compressed between a band and mooring rings with O-rings located above the fabric.
  • Fig. 9 shows an embodiment employing mooring rings which are integral to the inflation canister.
  • Fig. 10 illustrates in partial cross section a toroidal air bag packed in the central hub of the steering wheel.
  • Fig. 11 illustrates a toroidal air bag mounted to an annular inflator and mounted around the central hub of the steering wheel where functional elements (horn, cruise control, etc.) penetrate the bag and inflator.
  • Fig. 12 illustrates the inflated bag surrounding the central hub of a steering column.
  • the present invention provides a gas bag 10 of a generally toroidal configuration which may be adjoined to a gas inflator 12 for disposition in opposing relation to a vehicle occupant during a collision.
  • the gas bag is formed from a tube of woven fabric 14 (Fig. 7) .
  • tubes may be formed directly on a weaving or knitting machine in a substantially continuous process such as by weaving with a double shed, or can be formed from a flat fabric through the introduction of a single seam along its length.
  • one end of a formed tube 14 is clamped around the discharge ports 16 of a gas inflator 12 after which the other end of the tube is drawn down through the interior of the tube and attached to the inflation device so as to form an annular opening between the two ends.
  • the inflator 12 may be attached to a module housing 22 in which is disposed a mooring ring structure 24 and a second mooring ring 26 disposed within and having a diameter less than the first. These rings are preferably held one within the other by a bolt 30.
  • both the first and second mooring rings structures preferable include flanged neck portions 32 for mating to clamp structures as may be used in holding terminal ends of the fabric tube 14 in place against the mooring rings.
  • this attachment may be effected by stabilizing each end of the fabric tube 14 with a hem-like stitch line 34 (Fig. 3) .
  • the ends of the fabric tube 14 are then gathered together and passed over the flanged neck portion 32 of the mooring ring (Fig. 5), after which a band 38 is placed around the exterior to hold the fabric tube in place against the flanged neck of the mooring ring (Fig. 6) .
  • Figs. 8(a) - 8(e) By way of example only and not limitation, several potentially preferred arrangements for mooring the sectioned end of fabric tube 14 in place are shown in Figs. 8(a) - 8(e).
  • a tapered band 40 is utilized which, when tensioned by the fabric 14 moves up a mating taper on an opposing mooring ring 42 to hold the fabric securely in place.
  • a resilient strip 42 is disposed between a band 44 and a mooring ring 46.
  • O-rings 50 are utilized to further stabilize a fabric between a band 52 and a mooring ring 54.
  • mooring rings may be integrated to the inflator 12 thereby permitting direct attachment of the ends of the fabric 14 thorough the use of a lower band 58 and an upper band 60 between which are disposed a plurality of gas opening 62 for discharging an inflation medium into the opening formed between the two clamps.
  • any desired aspect ratio (i.e. width to height) of the gas bag 10 may be achieved.
  • an aspect ratio may be achieved through use of a starting fabric tube wherein the ratio of length to height is approximately equal to Pi.
  • One potential benefit of the present invention is the ability to control venting characteristics within the gas bag structure through adjustment of the weaving procedures followed during formation of the fabric tube. That is, the weave may be either tighter or looser in various portions of the fabric which is then formed into the bag so as to provide built in venting means rather than the use of formed vents which are typically used in the industry.
  • the fabric closest to the occupant will have a relatively low air permeability due to a tightly woven construction, while the fabric closest to the inflator preferably has a relatively higher air permeability due to a more loosely woven construction.
  • the application of a variation in weave density to in the fabric tube 14 forming the gas bag io of the present invention is illustrated through reference to Figs. 1(b) and 7.
  • the fabric tube 14 may include alternating segments of loose weave high permeability material 70 and tight weave, lower permeability material 72 (Fig. 7) .
  • the fabric tube 14 is segmented at the boundary 74, 76 so as to dispose a loose weave section at either end of the fabric tube to be used, the formation of the gas bag according to the prior description will result in the placement of the higher permeability material in the area closest to the inflator.
  • a toroidal gas bag io according to the present invention and utilizing the attachment scheme of Fig. 9 is illustrated in partial cross section packed in the central hub 78 of a steering wheel 80.
  • Fig. 11 illustrates a toroidal air bag according to the present invention mounted to an annular inflator for disposition around the central hub of a steering wheel where function elements such as a horn, cruise control, telephone, etc. penetrate the interior of the bag and inflator thereby permitting inflation of the bag surrounding the central hub in the manner illustrated in Fig. 12.
  • the gas bag according to the present invention may be disposed either in direct opposition to a vehicle occupant sitting in front of the steering wheel or may likewise be disposed in hidden view within the steering column itself which may be desired from aesthetic and function purposes should other components be required to occupy the central portion of the steering hub.

Abstract

Présentation d'un ensemble Airbag (10) de forme essentiellement toroïdale, fait avec une coupe de matériau tubulaire (14). Le matériau tubulaire est attaché à un dispositif de gonflage (12) de telle manière qu'une ouverture annulaire est formée entre les bouts du matériau tubulaire. Dans un mode de réalisation préféré, des anneaux d'accrochage (32) sont disposés de façon à former un passage annulaire pour le gaz de gonflage. En se gonflant, le matériau tubulaire prend la forme d'un tore déformé dont l'axe de symétrie rejoint celui de l'occupant du véhicule en cas de collision. Cette configuration supprime la nécessité de prévoir des coutures et des joints partageant la charge, comme c'est le cas dans les Airbag traditionnels.
