A rear vehicle seat airbag module configured to be mounted to a portion of a seat back of a front vehicle seat comprising an inflator and an inflatable cushion comprising a lower portion, an upper portion and an external tether connecting the lower portion and the upper portion. The inflator provides inflation gas to the inflatable cushion and the inflatable cushion is configured to deploy forward of an occupant seated in a rear seat of a vehicle by curving away from the occupant. The external tether is configured to control a trajectory of the deployment of the inflatable cushion by pulling the upper portion toward the lower portion to curve the inflatable cushion such that the upper portion is located above the lower portion.

An airbag includes a main bag section and a center bag section deployable to protrude towards a vehicle interior out of an inboard side of the main bag section. An inboard-side member, which forms the inboard side of the main bag section, is composed of a front component and a rear component. The center bag section includes a front wall and a rear wall. The front wall is composed of a rear extended region of the front component which is disposed in such a manner as to protrude rearward out of the rear edge of the front component. The rear wall is composed of a front extended region of the rear component which protrudes forward out of the front edge of the rear component and has a generally identical outer contour to the rear extended region. The center bag section is formed by jointing outer edges of the front and rear extended regions.

An airbag is a passenger seat airbag that inflates and deploys between a passenger seat and an instrument panel, and has side vent holes and a front vent hole. When an inflator is actuated in a state where a passenger close to the instrument panel exists, a valve cloth opens the front vent hole with the vicinity of the front vent hole away from the windshield.

A side airbag device-installed vehicle seat including: an inner bag section that extends out from a side airbag main body, past a seat front of a side frame, and to a seat width direction inner side of the side frame, and that inflates within a side section of a seatback when an internal portion of the inner bag section in communication with an inside of the side airbag main body is supplied with gas from a gas generator; and a reaction force member including a fixing portion that is fixed to the side frame, and a reaction force application portion that is interposed between the inner bag section and the side frame at the seat width direction inner side of the side frame and that applies reaction force to the inner bag section during inflation, the inner bag section being anchored to the reaction force application portion.

Multi-chamber airbag systems for use in aircraft and other vehicles are described herein. In some embodiments, an occupant restraint system includes a multi-chamber airbag that deploys from an occupant restraint (e.g., a lap seat belt) in an aircraft. The multi-chamber airbag can include a first portion that inflates generally upward in front of the occupant's torso, and a second portion that inflates in front of the first portion. The first portion and/or the second portion can include multiple chambers (e.g., generally cylindrical-shaped chambers) that, when inflated, provide the airbag with a shape and/or contact surfaces which can help to maintain the position of the airbag between the occupant and a strike object or hazard. In other embodiments, multi-chamber airbags configured in accordance with the present disclosure can me mounted to a structure (e.g., a monument, console, seat back, etc.) positioned generally in front of the occupant. The structure-mounted airbag can deploy generally toward the occupant in the event of a vehicle impact or other potentially harmful event to protect the occupant from impact injury.

An airbag venting device (10) for controlling an internal pressure of an airbag (12) of a vehicle occupant safety system (5) comprises a housing (24) which includes a first flow orifice (18) facing away from the airbag (12) and a second flow orifice (20) facing the airbag (12), wherein the housing (24) has an axial total length (26), the first flow orifice (18) has a first axial opening length (34) and the second flow orifice (20) has a second axial opening length (34). Moreover, the airbag venting device (10) includes an adjustable closure element (22) assigned to the housing (24) which, in a closing position, closes and, in an open position, releases at least one of the two flow orifices (18, 20), and an actuator device (30) provided at a front end (28) of the housing (24). The actuator device (30) interacts with the closure element (22) to release and/or to close the flow orifice (18, 20), and, in doing so, the axial total length (26) of the housing (24) is less than 3 times the length of the longer axial opening length (34) of the two flow orifices (18, 20).

An airbag inflator includes a lower pressure vessel supporting an initiator assembly, a booster can centrally mounted in the lower pressure vessel and secured to the initiator assembly, and an energetics canister secured over the booster can such that the energetics canister is positioned radially between the lower pressure vessel and the booster can. An energetics cover encloses a circumferential space between the booster can and the energetics canister. A flow diverter closes the booster can and includes inlet vent openings downstream of the energetics cover. An upper pressure vessel positioned over the flow diverter and engaging the lower pressure vessel includes an exit orifice sealed with a rupturable membrane. A manifold is secured over the upper pressure vessel. The inflator increases combustion efficiency and lowers gaseous effluents.
