Abstract
A side airbag apparatus includes a support part having a reaction force surface for receiving the deployment force of an airbag upon expanding and deploying the airbag. An inflator is fixed to the support part. A variable mechanism is configured to attach the support part to a seat frame such that the angle of the reaction force surface is variable with respect to the seat frame.
Claims20
A side airbag apparatus for attachment to a seat frame of a vehicle seat, the side airbag apparatus comprising:
- an airbag;
- an inflator for supplying, to the airbag, gas for expansion and deployment;
- a support part having a reaction force surface for receiving a deployment force of this airbag upon expanding and deploying the airbag, with the inflator fixed to the support part;
- and
- a variable mechanism configured to attach the support part to the seat frame such that an angle of the reaction force surface is variable with respect to the seat frame, the variable mechanism including an actuator for rotating the support part to the sear frame, the actuator including a power source and a power transmission part coupling the power source and the support part, the power transmission part operative to transmit power from the power source to the support part to rotate the support part.
A side airbag apparatus for attachment to a seat frame of a vehicle seat, the side airbag apparatus comprising:
- an airbag;
- an inflator for supplying, to the airbag, gas for expansion and deployment;
- a support part having a reaction force surface for receiving a deployment force of this airbag upon expanding and deploying the airbag, with the inflator fixed to the support part;
- and
- a variable mechanism configured to attach the support part to the seat frame such that an angle of the reaction force surface is variable with respect to the seat frame, the variable mechanism including a rotation holding part and an actuator, the rotation holding part for rotatably supporting a first end of the support part on the seat frame, the actuator for applying force to a portion different from the first end in a portion of the support part so as to rotate the support part about the rotation holding part.
A side airbag apparatus for attachment to a seat frame of a vehicle seat, the side airbag apparatus comprising:
- an airbag;
- an inflator for supplying, to the airbag, gas for expansion and deployment;
- a support part having a reaction force surface for receiving a deployment force of this airbag upon expanding and deploying the airbag, with the inflator fixed to the support part;
- a variable mechanism configured to attach the support part to the seat frame such that an angle of the reaction force surface is variable with respect to the seat frame;
- a cover attached to the support part and covering the airbag;
- and
- a pressing member attached to the cover and operable to press a seat back with an internal seat frame from the inside thereof;
- wherein, as an angle of the reaction force surface is varied by the variable mechanism, the pressing member is movable so as to deform the seat back.
