A gas generator includes a housing and a partition portion dividing a space in the housing into a combustion chamber accommodating a gas generating agent and a filter chamber accommodating a filter. The partition portion includes a first region which opens at the time of activation by being located to be opposed to a hollow portion of the filter and an annular second region which does not open even at the time of activation by being located to be opposed to a portion of an axial end surface of the filter except for the hollow portion. The second region is provided with a large-thickness portion constructed to be greater in thickness than the first region and opposed to an outer edge portion of the axial end surface of the filter, and the large-thickness portion is constructed to gradually be greater in thickness from an inner circumferential end portion toward an outer circumferential end portion.

An inflator and airbag are fixed by a fixing member including a lower fixing member that supports and fixes the inflator from a lower surface side of a plate portion. The lower fixing member has a tubular wall portion and a flange portion formed at an opening at one end. The tubular wall portion has an inner surface in a shape that is fitted to a circumferential wall surface, including a lower annular step surface, of the inflator housing. The flange portion has a plurality of bolt holes and abuts against a lower surface of the plate portion. The airbag and the lower fixing member are fixed with a bolt and a nut mounted through the airbag, the plate portion, and the flange portion of the lower fixing member.

An igniter carrier (4) for an igniter unit (1), particularly for a gas generator, including a first receptacle section (8) for an igniter (2), a second receptacle section (9) and a connecting section (7) for attaching the igniter unit (1), wherein the igniter carrier (4) is prefabricated from a plurality of individual parts joined together and can be assembled in an assembly process as an individual part (4) of an assembly (1) together with an igniter (2) and a connector part (3) is provided. An igniter unit (1), particular for a gas generator, including such an igniter carrier (4), to an igniter (2) and to a method for producing such an igniter unit (1) is provided.

An initiator for a gas generator of a vehicle safety device. The initiator is actuatable by an electrical power source having a ground wire and includes a cup defining an interior for receiving a pyrotechnic material and a pair of electrical pins extending from the cup and arranged to be in reaction initiating communication with the pyrotechnic material through a bridge wire. The initiator additionally includes an over-molded body having a first end defining a pocket for receiving the electrical power source and a mounting ring extending around a least a portion of a periphery of the over-molded body. The initiator further includes an electrically conductive member providing electrical communication between the mounting ring and an inner diameter of the pocket. The electrically conductive member is molded in place within the over-molded body.

The present invention provides a gas generator, including: a housing with a gas discharge port; an igniter assembly and a gas generating agent in the housing; and a metallic cup of constant inner diameter covering the igniter to define a charging chamber. The igniter assembly includes a main body, including an ignition portion and a electro-conductive pin integrated with a metallic collar by a resin. The metallic collar has a fixing portion inserted into a hole in a bottom surface of the housing and a remaining portion projecting inward from the bottom surface of the housing, and a guide portion. An inner circumferential wall surface of the metallic cup and an outer circumferential wall surface of the fixing portion are press-fitted, and an annular gap is formed between the inner circumferential wall of the metallic cup member and an outer circumferential wall surface of the guide portion.

A vehicle side airbag device includes a side airbag, an inner tether that extends in the seat forward direction at the seat width direction inner side of the side airbag in the inflated and deployed state and has a distal end portion anchored to the side airbag, and an outer tether that extends outward in the seat width direction from the seat rear side of the side airbag in the inflated and deployed state and has a distal end portion anchored to the side airbag. An upper end portion of the distal end portion of the outer tether is positioned further toward an upper end side of the side airbag than an upper end portion of the distal end portion of the inner tether.

The present invention provides an inflator including a rupturable plate closing between the ignition device chamber having a gas discharge port and the pressurized gas chamber filled with a pressurized gas; a partition wall provided with a rod axially separating an interior of an ignition device unit housing, corresponding to the ignition device chamber, into two chambers; a combustion chamber provided on the side of a first end of the ignition device unit housing and provided with an igniter, and a diffuser chamber having the gas discharge port and provided on the side of a second end, which is an opposite end to the first end, the rupturable plate being circular and having, a circumferential edge fixing portion and a circular non-fixing portion on an inner portion other than the circumferential edge fixing portion, a fragile portion formed by not less than three grooves provided on a first surface facing the bottle, the grooves extending from a circumference of the circular non-fixing portion or from positions in the vicinity thereof, as a start point, toward a center of the circular non-fixing portion such that each of end points of the grooves does not reach the center of the circular non-fixing portion, the rod fixed to the partition wall and extending toward the rupturable plate, and the rod colliding with the rupturable plate due to a gas pressure generated by activation of the igniter, coming into contact with all of the end points in the fragile portion and rupturing the rupturable plate.
