Abstract: A novel airbag curtain fold configuration for a safety restraint system, especially well suited to protect occupants of a vehicle from lateral impact is described. One or more airbag curtains are provided to inflate between an occupant and a lateral surface, such as a door or side window. The airbag curtain includes a first and second side. A fold portion is configured adjacent the first side and a rolled portion is configured opposite the fold portion adjacent the second side of the airbag. Attachment tabs may extend from an edge of the airbag curtain beyond the rolled and fold portions to facilitate attachment of the airbag curtain to a vehicle as part of an airbag system. A method for folding an airbag curtain is described. A first edge of the airbag curtain is folded to a position adjacent a first side of the airbag curtain.

Abstract: An air-bag arrangement for use in a motor vehicle, secured to the vehicle at points along a non-linear line above an opening in the vehicle. The arrangement incorporates an inflatable element, connectors to secure an edge part of the inflatable element to the vehicle, and an inflator to inflate the inflatable element. The invention also incorporates a tether arrangement including a first and second tether. The first tether has opposed ends secured to the inflatable element. The second tether has a first end associated with the first tether intermediate its ends and a second end secured to the motor vehicle. When the inflatable element is inflated, a lower region of the inflatable element and the tethers extend between two opposed ends of the non-linear line and are substantially taut.

Abstract: An attachment assembly for attaching a cushion member for an airbag apparatus to a vehicle surface is disclosed. The attachment assembly is particularly useful for attaching curtain type cushion members, as for a side impact airbag system. The attachment assembly may include a protrusion with a rod and a knob larger than the rod. A compressible spring washer is affixed to the rod. A hole formed in a mounting portion of the cushion member is then fitted around the rod, outside the washer. A cap is affixed to the rod to keep the cushion member in place. The protrusion, with the attached cushion member, may then be affixed to the vehicle surface through the use of a keyhole formed in the vehicle surface. The knob is pushed longitudinally into a larger, clearance portion of the keyhole, such that the spring washer is compressed. Then, the protrusion is moved transversely into an engaged configuration, in which the knob and the spring washer engage the interference portion.

Abstract: An air-bag arrangement for use in a motor vehicle is often secured to the vehicle at points extending along a non-linear line located above an opening in the vehicle. The arrangement incorporates an inflatable element, connectors to secure an edge part of the inflatable element to the vehicle, and an inflator to inflate the inflatable element. The air-bag arrangement also incorporates a tether arrangement including a tether of elongated form having first end secured to the inflatable element adjacent the connectors and the second end secured to the vehicle. The tether movably passes through a guide located adjacent one end and the lower region of the inflatable element. Advantageously, when the inflatable element is inflated, a lower region of the inflatable element is taut and, together with the tether, extends between the two opposed ends of the non-linear line.

Abstract: An air-bag arrangement for use in a motor vehicle comprises a gas generator(9) which generates gas when an accident occurs. An air-bag is provided to be inflated by the gas. The air-bag comprises three super-imposed fabric layers(2,3,4), the outer peripheries of which are conjoined by a seam(5). A central aperture(6) in the lower-most layer receives the gas outlet(8) of the gas generator. A plurality of apertures(12) are formed in the intermediate layer and seams(13) interconnect the intermediate layer(3) and the lower-most(2) adjacent the apertures. The seams(13) partially surround each aperture, but are not present in a region(14) which is radially outwardly positioned relative to the center of the intermediate layer(3). This arrangement causes the bag, on inflation, to inflate laterally outwardly before inflating towards the occupant of the vehicle to be protected by the bag.

Abstract: An apparatus (10) includes a vehicle part (16) with a structural portion (44) and a trim portion (50) covering the structural portion (44). An air bag module (30) is located within a deployment opening (56) in the trim portion (50) of the vehicle part (16). A deployment structure (70) closes the deployment opening (56). The deployment structure (70) consists of a single, continuous body of molded plastic material, and includes a deployment door (78 or 80) partially bounded by a stress riser (82) in the plastic material. The module (30) is mounted on the structural portion (44) of the vehicle part (16). The deployment structure (70) is fully supported on the vehicle part (16) by the trim portion (50) separately from the module (30) and the structural portion (44).

Abstract: A side impact air bag module (10) includes an air bag (30) and an inflator (32) which is actuatable to provide inflation fluid for inflating the air bag. The air bag (30) includes first and second main body portions (70, 120) and a first retainer portion (80) which is disposed between the first and second main body portions. The first retainer portion (80) and the first main body portion (70) of the air bag (30) at least partially define a pocket (200) in the air bag in which the inflator (32) and a diffuser (34) are disposed. Stitching sections (182b, 184b) close two sides of the pocket (200).

Abstract: An inflatable vehicle occupant protection device (14), such as an air bag, includes first and second inflatable structures (72,74). The first inflatable structure (72) has an inflated location between the occupant's thorax and a side portion (20) of the vehicle. A second inflatable structure (74) has an inflated location between the occupant's head and the side portion (20) of the vehicle. A valve (80) increases the pressure of inflation fluid in the second inflatable structure (74) in response to engagement of the occupant's thorax with the first inflatable structure (72) prior to subsequent engagement of the occupant's head with the second inflatable structure (74).
