At the inner side of the diffusor (22) delimiting the receiving opening (24) at least one bearing surface (34) and at least one gas guiding surface (30) are provided, wherein the bearing surface (34) bears directly against the outer housing (14) of the inflator (10) and the gas guiding surface (30) is radially spaced apart from the outer housing (14) while forming at least one collecting chamber (30) into which gas flowing out of the outflow area (16) is flowing. The collecting chamber (32) opens into at least one outlet opening (36) through which gas exits the diffusor (22) in an outlet direction (R.sub.D) transversely to the outflow direction out of the inflator (10).

An airbag device includes an airbag, a case in which the folded airbag is housed, and an airbag cover that covers the folded airbag. An attachment portion of the airbag cover is attached to a peripheral wall portion of the case by a rivet being caused to pass through. The case is such that a vicinity of a boundary region between the peripheral wall portion and a bottom wall portion is curved in an approximate arc in cross-section. The attachment portion includes a protruding portion that protrudes toward the peripheral wall portion side in an end edge farther to a leading end side than a region of penetration of the rivet. The protruding portion is disposed in a position opposing a curved region configuring a boundary region between the peripheral wall portion and the bottom wall portion, and is protruded in such a way as to be oriented farther to a central side of the bottom wall portion than an outer side face of the peripheral wall portion, and an edge on the peripheral wall portion side of a protruding end face is disposed in a state of non-contact with the curved region.

An airbag apparatus includes a gas generator and an airbag. The gas generator includes a gas generator main body and at least one mounting protrusion. The airbag includes a first fabric portion, a second fabric portion, and a storage chamber located between the first fabric portion and the second fabric portion. Part of the storage chamber is constituted by the first fabric portion. The storage chamber includes as insertion port, which allows the gas generator to be inserted, and one or more mounting holes, which allow the at least one mounting protrusion to be passed. The rearmost one in the insertion direction of the one or more mounting holes is a rearmost mounting hole. The storage chamber further includes an opening promoting portion, which is located between the insertion port and the rearmost mounting hole and causes the insertion port to open.

An airbag apparatus includes a gas generator main body and an airbag. The gas generator main body includes a gas outlet portion, which includes gas discharging holes, and a non-outlet portion. The airbag includes an inflation portion, which is inflated by inflation gas, and a storage chamber, which is arranged outside the inflation portion and stores the gas generator main body. The storage chamber includes an insertion port for inserting the gas generator main body and a partition wall. The partition wall includes a pass-through portion through which the non-outlet portion is passed. The partition wall separates the storage chamber and the inflation portion from each other and restricts leakage of inflation gas in the inflation portion to the storage chamber through the gap between inner wall surface of the pass-through portion and the non-outlet portion.

This invention relates to a side airbag device stored inside a vehicle seat and fixed to a side frame. The device includes an airbag that expands and deploys to restrict an occupant; an inflator that supplies expansion gas to the airbag; and a bracket connected to the side frame that holds the airbag and the inflator. The airbag includes a prepush chamber having an inflator stored therein and mainly deploys inside of the side frame; and a main chamber connected to the prepush chamber and mainly deploys forward of the side frame. The bracket includes a first surface oriented in the forward direction of the vehicle; and a second surface oriented to the inside of the seat in the width direction of the vehicle. When the airbag is stored by being folded and/or rolled, at least the main chamber is disposed on the first surface of the bracket.

The present invention relates to an inflator mounted on protective equipment, comprising: a main body (100) having a cylindrical structure that is open at the top and bottom thereof, wherein the main body (100) has a key-ball insertion hole (110) and a gas supply hole (120) that are formed on portions of a lateral side thereof, and a bomb (600) for storing compressed air is coupled to the lower side of the main body (100); an eccentric lever (200) that is rotatably coupled to the upper opening of the main body (100) through a rotation shaft (230) and includes a lever (210) that adjusts a downward pressure by rotating an eccentric drum part (220) having the shape of a circular plate; a perforation part (300) that provides a restoring force downward according to the pressure state of the eccentric lever (200) and perforates the bomb (600) to allow the gas in the bomb (600) to be supplied to a user's protective equipment through the gas supply hole (120); and a key-ball (400) that confines the movement of the perforation part (300) while being inserted into the key-ball insertion hole (110) and separates from the key-ball insertion hole (110) according to the state of the outside to operate the perforation part (300).

An airbag device for a car may include an inflator positioned between first and second seats and generating an operating gas, a chamber part receiving the operating gas generated by the inflator and expanding between the first and second seats, a tether part connected to the chamber part to control a deployment shape of the chamber part, and a locking release part connected to the tether part at an inner surface or side surface of the chamber part which removes the connection to the tether part according to a control signal.

A high strength dual-swaged airbag inflator vessel comprising a high strength metal material, such as low carbon steel, has a swaged terminal end defining two distinct swaged portions. A reduction of diameter within one of the swaged portions is restricted to be less than or equal to about 30% and in certain variations, less than or equal to about 16% to minimize cold work strain hardening and to reduce loss of ductility. In certain aspects, a second swaged portion within the swaged terminal end has a length of less than or equal to about 10 mm. Methods for making such a dual-swaged airbag inflator vessel are likewise provided. Such dual swage designs have improved reliability and performance in high pressure inflator applications, as well as reduced manufacturing costs.
