A passenger protection apparatus includes an inflator and an airbag. The inflator is configured to supply gas. The airbag is configured to deploy to surround a sitting position of a passenger by the gas supplied from the inflator. One end of the airbag is supported on an upper portion of a vehicle, and the other end of the airbag contacts an in-vehicle member and is supported by the in-vehicle member.

Airbag assemblies are disclosed that can reduce rotational velocity of an occupant's head during a collision event and thereby mitigate traumatic brain injury/head injury to an occupant. An airbag includes a pair of lobes or protrusions to deploy and extend from the rear face of the airbag on either side of the occupant's head to limit rotation of the head. A pair of vertical tethers within an interior of the airbag configure the lobes and contour the rear face to form one or more low fabric tension zones or bubbles. The lobes maintain high fabric tension, similar to a pressurization of a main inflatable chamber of the airbag.

A vehicle seat includes a seat back frame, an elastic installation supporting member installed in the seat back frame, and an airbag within a seat back, the vehicle seat causing the airbag to inflate and develop within the seat back. An inflator is attached to the seat back frame. An inflation and a development of the airbag in the seat back due to an operation of the inflator allows the airbag to elastically support an upper body of a seated person and to elastically receive an impact force which is applied to a rear of the seat back.

A seat assembly having an occupant protection system. The occupant protection system may have a deployable shield. The deployable shield may extend around multiple sides of the seat assembly may extend at least partially around a front of a seat occupant when deployed, may be deployable along a dynamic deployment path based on a detected position of a seat occupant, or combinations thereof.

A vehicular occupant restraining device, that includes: an inside air bag arranged on an inner side, in a vehicle width direction, of a side frame in a side section, the inside air bag receiving a gas supply from a second inflator, the inside air bag deploying by inflation in the side section earlier and at a higher pressure than a side air bag, and the inside air bag pressing a seated occupant to an inner side in the vehicle width direction. The inside air bag is configured so as to deploy by inflation in a region more to a vehicle upper side than a second-from-bottom rib of six ribs provided in a torso of an AM50 type international standard side collision dummy, in a state in which the dummy is seated in the vehicular seat.

An impact absorption assembly for a seat back is provided having a deformation zone as least partially disposed above a top surface of a seat back structure. The deformation zone deforms plastically upon an impact from a rearward direction.

An airbag of a rear-seat airbag device includes an deployment part which is deployed from a seatback of a front seat toward the vehicle rearward side and then toward a vehicle downward-and-forward side up to the seatback when the airbag is inflated and deployed, and the deployment part includes a stretch portion which is stretchable according to a tension acting on a tip portion of the deployment part when the airbag is inflated and deployed.

The side airbag device includes an inflator and a side airbag that is stored in a folded state in a side portion of a seatback of a vehicle seat and is inflatable and deployable in a space between a vehicle sidewall and a side portion of an occupant. The side airbag includes an outer bag and an inner bag. The inner bag houses the inflator and is disposed at a rear portion of the outer bag along an extending direction of the seatback. The outer bag is provided with a vent hole configured to communicate with an outside. The inner bag is provided with a gas circulating hole configured to communicate with the outer bag. The gas circulating hole is disposed at a position to be blocked by the outer bag when the side airbag in an inflated and deployed state is pressed between the occupant and the vehicle sidewall.

A backrest for a vehicle seat having a backrest side rail for supporting a side of a body of an occupant sitting on the vehicle seat, having an airbag and having a gas generator for protecting the occupant, having a hard cover housing for arrangement on the backrest side rail, wherein the hard cover housing in a lateral plan view is designed as a half shell arranged along a longitudinal extent of the backrest side rail with two longitudinal edges spaced from one another, wherein the airbag and the gas generator can be pushed in and/or are pushed in between the two longitudinal edges.

An airbag device capable of restraining a motor vehicle occupant in a stable position even in an oblique collision. The airbag device includes a bag-shaped main bag inflated and deployed on a vehicle front side of the passenger seat, a bag-shaped center bag inflated and deployed on the inner side of the main bag in the vehicle widthwise direction, and a slit that provides a separation between the main bag and the center bag on the vehicle rear side. A rear end part of the center bag is inclined to gradually protrude rearward in the vehicle as the rear end part is extended upward and protrudes further to the vehicle rear side than at least the main bag.
