A side airbag device including a cushion (104), an inflator (110), and a structure such as a rotating shaft (140) built in a seat (102). The inflator (110) has a gas ejection hole inside the cushion (104), a connector (136) on the other end side, and a stud bolt (112). The cushion (104) has a bag-shaped chamber (114), an extension portion (124) into which the inflator (110) is inserted, and a predetermined tab (118) held in the vicinity of the other end side of the inflator (110). The rotating shaft (140) is disposed to pass through a space portion (E1) surrounded by the chamber (114), the extension portion (124), the inflator (110), and the tab (118), and the cushion (104) is attached to the seat (102) by the stud bolt (112).

A deflector for a diffusor of a gas generator of an airbag module is disclosed. The deflector comprises a substantially tubular deflector base body and a gas discharge device connected thereto, wherein the gas discharge device has a substantially rectangular base and two outflow regions on opposite sidewalls so that gas can flow substantially in opposite directions along the longitudinal axes of the tubular deflector base body out of the interior of the gas discharge device to the outside.

In an assembly group comprising a cap of a tubular gas generator and a deflector element that deflects gas flowing out of at least one outflow opening of the cap to at least one discharge opening of the deflector element, a deflection surface of the deflector element is arranged radially outwardly of the outflow opening. At least two securing arms of the deflector element extend through the outflow opening and engage behind an edge defining the outflow opening on an inside in a positive connection with the cap. The cap is fixed firmly to an axial end of the tubular gas generator. Subsequently, the deflector element is slid from an outside of the cap with its securing arms through the outflow opening, the securing arms forming a positive connection with the edge of the outflow opening which fixes the deflector element firmly to the cap.

An occupant protection device for a vehicle includes: a three-point seatbelt device having a seatbelt extendable across a front of an upper body of an occupant sitting on a seat; and a belt airbag device including a belt airbag that is provided at a shoulder belt section, which is extendable from a shoulder to a waist of the occupant, of the seatbelt the belt airbag being configured to be deployed when a collision occurs. The belt airbag includes a belt-direction deployment section extendable and deployable along the shoulder belt section, and an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section. The belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat.

Airbag inflator system including a housing defining a flow passage leading into an interior of an airbag). A reverse flow valve is arranged at an inlet end region and selectively enables connection of the flow passage to ambient atmosphere dependent on a pressure differential on opposite sides of the reverse flow valve. A gas generator is arranged in connection with the housing. An activation system provides a signal to the gas generator to cause generation of gas. An aspirator is arranged between the reverse flow valve and the outlet end region and includes an inlet portion alongside the reverse flow valve and an aspiration portion partly separated from the inlet portion to define at least one opening in flow communication with the gas generator. The aspirator is preferably configured to generate gas flow in accordance with the Prandtl-Meyer effect.
