PROBLEM TO BE SOLVED: To increase fabric utilization per tether and to save the overall cost per finished air bag by air bag tethers and a pattern-wise arrangement of such tethers in relation to air bag panels on a fabric blank.SOLUTION: The air bag tether system includes two congruent tether panels that are joined to one another and to a respective air bag panel. In a preferred embodiment, the tether panel 14 that is attached to the face panel of the air bag is cut in alignment with the warp and the fill of the fabric blank, while the rear tether panel 16 that is attached to the rear panel of the air bag is cut on the bias with respect to the warp and the fill of the fabric blank. The two tether panels are then connected to one another to form a functional tether system. This two-piece construction, with one bias-cut piece, decreases the amount of fabric that is used in the manufacture of the air bag and tethers, while providing sufficient elongation for the tether system to be functional.

PROBLEM TO BE SOLVED: To provide an inflator apparatus wherein molecular weight of mixed gas contained therein is manipulated, by varying relative amounts of various constituents thereof. SOLUTION: Through such manipulation and tight control of mixed gas molecular weight, performance of the inflator can be properly tuned so as to desirably control or influence a speed of deployment of an associated airbag cushion, and minimize or reduce damage to the associated airbag cushion caused by an excessive deployment speed, as well as satisfy the relatively onerous inflation demands required for proper or desired operation of various close proximity airbag cushions or inflatable restraint devices.

Abstract:
PROBLEM TO BE SOLVED: To perform rapid vertical or lateral development of an air bag body to regulate a jump-out amount to the passenger side during developing expansion of an air bag body and protect a passenger, to improve passenger protection performance, and to simplify constitution and reduce weight. SOLUTION: This air bag comprises a main base cloth 13 on the passenger side and a main base cloth 15 on the mounting side. The outer peripheral edges 13a and 15a of the main cloth 13 on the passenger and the main base cloth 15 on the mounting side are sewn together to form a sewn part 19. An extension part 21 is formed in a protruding state at the outer peripheral edge 13a or 15a, positioned opposite to each other in a folding state, of the base cloth 13 on the passenger side or the main base cloth 15 on the mounting side or the main base cloth 15 on the mounting side. The extension parts 21 are intercoupled through sewing and a slit is formed in the extension part 21.

PROBLEM TO BE SOLVED: To provide an assembly including a supporting housing and an actuating device.SOLUTION: An assembly comprises: a supporting housing; and an actuating device. The actuating device includes an extendable cup for an initiator, and the cup includes at least one non-irregular bending part and defines a storage chamber including a reactive filler generating a reactive product at at least one part of the cup. The extendable cup for the initiator is bent to form a pocket including one part of a movable element. The extendable cup for the initiator extends in a longitudinal direction from a first length to a larger second length during starting a reaction of the reactive filler. At least one part of the extendable cup for the initiator and the movable element is located inside a hole extending in a longitudinal direction of the supporting housing. The extending cup for the initiator moves the movable element inside the hole. The supporting housing is effective for limiting lateral extension of the extendable cup for the initiator during starting the reaction of the reactive filler.
Abstract:
PROBLEM TO BE SOLVED: To operate an initiator as designed by minimizing exposure of the initiator to electrostatic energy.SOLUTION: An inflator assembly includes an inflator housing and the initiator 12 attached to the inflator housing. A varistor 58 is associated with the initiator 12, and the varistor 58 is spaced apart from the surface of the inflator housing to form a first spark gap between the varistor and the surface of the inflator housing.
Abstract:
PROBLEM TO BE SOLVED: To manufacture an air bag expansion device assembly in which a filter for reducing the internal pressure of an expansion device is obtained by winding a metal net material hollow cylindrical core in spiral to form a combustion inside tube. SOLUTION: A strip of wire mesh or expanded metal is cut in length matching with the diameter of a tube. A combustion filter tube is formed by winding three layers of wire woven fabric or expanded metal on a mandrel. Next, the tube is removed from the mandrel and is cut in prescribed length of a filter. The figure shows a completed passenger side combustion filter cut in prescribed length of 1' and having weld zones 21 at the tube end parts. The filter 20 has an inside diameter of 1.433" (3.64cm) and an outside diameter of 1.590" (5.04cm).
