Abstract: An initiator is incorporated in an inflator in order to trigger the inflator through propagation of flame from an initiating explosive to a gas generator of the inflator. The initiator includes a closed-bottomed tubular capsule for accommodating the initiating explosive. A tubular portion of the capsule includes a plurality of rupture-accelerating means (grooves each having a V-shaped cross section) for accelerating rupture upon ignition of the initiating explosive, whereby flame propagates from the initiating explosive to the gas generator of the inflator along a plurality of directions.

Abstract: According to a small number of types classified among all passenger vehicle models on the basis of a distance between front and rear seats (Sf, Sr), supply parts for an airbag module (10, 110) including an airbag (11, 111), a tension cloth (12) and an inflator (14) include a small number of types of the airbags (11, 111) including an expansion portion for front seat (11c, 111c) which covers protection ranges for the front seats (Sf) of a plurality of vehicle models included in the respective types and an expansion portion for rear seat (11d, 111d) which covers protection ranges for the rear seats (Sr) of a plurality of vehicle models included in the respective types, a small number of types of tension clothes (12) a shape of which is determined to cover a plurality of vehicle models to be equipped with the respective airbags (11, 111), and a single type of inflator (14) connected with a gas inlet (11a, 111a) provided in the respective airbags (11, 111).

Abstract: An initiator includes, as constitutive components, a pair of electrodes disposed with an insulator disposed therebetween; a bridge wire connected between the pair of electrodes and adapted to generate heat when energized; an explosive which detonates in response to heat generation of the bridge wire; and a casing that hermetically accommodates the bridge wire and the explosive. The insulator includes a step for enhancing the resistance of the insulator to pressure generated through detonation of the explosive when the insulator receives the thus-generated pressure. The step is formed such that the area of the explosive-side pressure reception surface of the insulator is greater than that of the counter-explosive-side pressure reception surface thereof.

Abstract: An initiator includes a pair of electrode pins, a conductive header, an insulator, a bridge wire, an explosive, and capsules. A bottom wall of the inner capsule has a protrusion projecting from the bottom wall. The thickness of an end wall portion of the protrusion is determined in such a manner that the end wall portion is the thinnest among a plurality of wall portions of the inner capsule. The thicknesses of the wall portions are set so as to increase gradually from the end wall portion of the protrusion toward the side wall of the inner capsule. Therefore, when the explosive is ignited for detonation, breakage of the inner capsule occurs in the vicinity of the end wall portion of the protrusion, and flame propagation energy generated by detonation of the explosive propagates in an intended direction.

Abstract: In a window air bag system in which an air bag (10) designed to be inflated into the shape of a curtain in a lateral region of a passenger compartment by being supplied with gas from an inflator (22) is stored in a folded state along a pillar portion (32) and a roof side rail (31). A hollow energy-absorbing member (51, 52) is disposed along a longitudinal direction of the p portion (32) and the roof side rail (31) in such a manner as to be contiguous to a position where the air bag (10) is stored state between the pillar portion (32) and pillar garnish (42) for covering the pillar portion (32) and between the roof side a side rail garnish (41) for covering the roof side rail (31). The direction of deployment of the air bag (10) can thus be st reducing the amount of the garnish (42, 41) protruding into the passenger compartment, spaciousness of the passenger compartment, good visibility, and considerable ease with which a passenger can get on and off the vehicle can be guaranteed.
