Abstract: An airbag device for a vehicle includes a gas supply portion, an airbag body, and a low-pressure portion. When a vehicle collision occurs, the gas supply portion injects gas into an airbag body. The airbag body has a single-chamber structure. When the airbag body receives the gas from the gas supply portion, the airbag body is inflated and deployed toward an occupant to restrain the shoulders of the occupant. The low-pressure portion is provided in the same area of the airbag body, which faces the occupant when the airbag body is inflated and deployed, to protect the occupant's head. When the airbag body is inflated and deployed, the low-pressure portion is inflated such that the pressure in the low-pressure portion is lower than the pressure in the airbag body.

Abstract: A side airbag has a lower chamber corresponding to the chest of the occupant and an upper chamber corresponding to the head of the occupant. A strap is provided at the boundary between the lower and upper chambers. The attachment position of a door-side attachment portion of the strap is higher than the attachment position of a seat-side attachment portion of the strap and lower than the upper end of a door trim or at the same height as the upper end of the door trim. Thus, the peripheral length from the upper end of a door-side base cloth of the side airbag to the door-side attachment portion of the strap is shorter than the peripheral length from the upper end of a seat-side base cloth of the side airbag to the seat-side attachment portion of the strap. As such, upon deployment of the side airbag, the upper chamber can be raised up toward a door window glass.

Abstract: Aside airbag has a lower chamber corresponding to the chest of the occupant and an upper chamber corresponding to the head of the occupant. A strap is provided at the boundary between the lower and upper chambers. The attachment position of a door-side attachment portion of the strap is higher than the attachment position of a seat-side attachment portion of the strap and lower than the upper end of a door trim or at the same height as the upper end of the door trim. Thus, the peripheral length from the upper end of a door-side base cloth of the side airbag to the door-side attachment portion of the strap is shorter than the peripheral length from the upper end of a seat-side base cloth of the side airbag to the seat-side attachment portion of the strap. As such, upon deployment of the side airbag, the upper chamber can be raised up toward a door window glass.

Abstract: A pinion of a pretensioner is provided at a side of a torsion shaft, which side is opposite a side connected integrally to a spool via a sleeve. A base lock of a lock mechanism is connected to the pinion. Due to the lock mechanism operating, a leg plate side end portion of the torsion shaft is locked. In this way, due to operation of the pretensioner, the pinion, which is connected to a rotating portion of a sleeve, also is locked by the locking mechanism. Therefore, a piston of the pretensioner is not lowered, and internal pressure of a cylinder does not affect deformation of the torsion shaft.
