An airbag apparatus according to the exemplary embodiment of the present invention includes: an airbag which is inflated when gas flows into the airbag, and has a left opening hole formed in a left surface, and a right opening hole formed in a right surface; and a cylinder which is disposed in the airbag while connecting the left opening hole and the right opening hole, and has a vent hole through which the gas flowing into the airbag is discharged.

An apparatus (10) for helping to protect an occupant (20) of vehicle (12) having a seat (16 or 22) for receiving the occupant (20) includes an inflatable protection device (14) inflatable from a stored condition in the vehicle (12) adjacent a reaction surface (19, 23 36) to a deployed condition between the reaction surface and the vehicle occupant (20). The protection device (14) includes a front portion (62) presented toward the seat (22) and an inflatable volume for receiving a penetrating occupant (20) when the protection device (14) is in the deployed condition. A rear portion (64) connected to the front portion (62) has an inflatable volume spaced from the front portion (62) by a space (110). The front portion (62) is positioned between the vehicle occupant (20) and the rear portion (64) when the protection device (14) is in the deployed condition. The inflated front portion (62) is movable in a fore-aft direction relative to the rear portion (64) to engage the occupant (20) regardless of the distance between the reaction surface (19, 23, 36) and the occupant (20).

A passenger protection device for a vehicle includes an airbag assigned to at least one passenger in a rear compartment of the vehicle. The airbag can be activated and filled with a gas in the event of an imminent collision of the vehicle being detected or in the event of a collision. The airbag is formed such that that it is deployed in the activated and filled condition between a front vehicle seat and an upper body region, as well as a between the front vehicle seat and a knee and lower leg region of the passenger.

An airbag apparatus according to the exemplary embodiment of the present invention includes: an airbag which is inflated when gas flows into the airbag, and has a left opening hole formed in a left surface, and a right opening hole formed in a right surface; and a cylinder which is disposed in the airbag while connecting the left opening hole and the right opening hole, and has a vent hole through which the gas flowing into the airbag is discharged.

An occupant protection device is provided including (1) an airbag that covers the head of the occupant, and that has (i) a front deployment section that is housed in a headrest, and that is deployed at a seat forward direction with respect to the head of a seated occupant, and (ii) a pair of left and right lateral deployment sections that are inflated and deployed at seat sides with respect to the head of the seated occupant, (2) a lifting mechanism that raises and lowers the vehicle seat, and (3) a controller that uses the lifting mechanism to lower the vehicle seat to an airbag deployable height in cases in which a vehicle collision has been determined to be unavoidable and a height of the vehicle seat is higher than the airbag deployable height, and that inflates and deploys the airbag after lowering the vehicle seat.
