A side airbag device includes an inflator; and a bag-shaped airbag inflatable and deployable in response to a gas upon activation of the inflator. The airbag includes a torso protection portion inflatable and deployable in a space beside a torso of the occupant, a support portion provided on a console box side of the torso protection portion and configured to be pushed onto a top surface of the console box in an inflated and deployed state, and a hip protection portion inflatable and deployable between a hip of the occupant and a lateral portion of the console box. The support portion and the hip protection portion are defined by a continuous chamber. The inflator is positioned from above to below the support portion in a side view of the vehicle. The airbag is mounted on a lateral portion of the vehicle seat via the inflator.

Side airbag device

There are provided a vehicle-body frame member forming an opening portion for entrance at a vehicle side part and a front side door provided so as to open and close the opening portion. The vehicle-body frame member comprises a side sill, the front side door comprises a door panel portion provided with an inner lower portion which overlaps with the side sill in a vehicle wide view and reinforcement portions provided at two side-portions of a peripheral part of the door panel portion which are continuous and include the inner lower portion such that the reinforcement portions overlap with the vehicle-body frame member in a vehicle side view.

Vehicle-body structure of vehicle

A side door comprises a door panel portion and a reinforcement portion (a lower-side reinforcement portion and others). The door panel portion is provided to cover an opening portion for entrance and configured such that its peripheral part overlaps with an opening-portion-forming vehicle-body frame member (a side sill and others) in a vehicle side view. The reinforcement portion is provided at the peripheral part of the door panel portion such that it overlaps with the opening-portion-forming vehicle-body frame member in the vehicle side view, thereby reinforcing the peripheral part of the door panel portion against a collision load applied to the side door from a vehicle side. The reinforcement portion is provided at a portion of the peripheral part of the door panel portion which includes a part corresponding to the vehicle-width-direction-extending vehicle-body frame member (a first floor cross member and others).

An air bag device to be installed in a vehicle provided with a front seat and a rear seat disposed away from each other in a front-rear direction of the vehicle, and a reclining mechanism provided in the front seat to allow a seat back to pivot about a reclining pivot axis includes an air bag that deploys from a back surface of the seat back of the front seat toward the rear seat. At least an upper rear portion of the air bag in a deployed state is formed into an arc shape about the reclining pivot axis in a side view of the vehicle.

Air bag device

A side airbag device includes an inflator and an airbag. The airbag includes a deployable bag and a separator that separates the bag into a first chamber and a second chamber. The first chamber includes a support inflation portion and a protection inflation portion. The support inflation portion is deployable in such a shape that it gradually broadens from its lower end portion toward its upper end portion along a seat-side portion. The protection inflation portion is deployable at one end side of the support inflation portion. The inflator is disposed to supply a gas into the support inflation portion. The separator includes at least one gas distribution hole in a portion thereof that separates the support inflation portion of the first chamber and the second chamber from each other. The second chamber is provided below the first chamber.

A curtain airbag device for a vehicle has a curtain airbag main bodythat is disposed along a longitudinal direction of a vehicle body while covered with an A pillar trimand roof trim, and folded in an A pillarand a roof side rail partof the vehicle body so as to be able to deploy downward within a cabin. The curtain airbag main bodyis provided with a twisted partthat is twisted such that an initial deployment force, generated upon inflation and deployment of the curtain airbag main bodylocated in a vicinity of the A pillar trim, is acted in a separation direction in which the A pillar trimis parted away from the A pillar part, to push open the A pillar trimtoward an inside of the cabin. At least an upper surface of the twisted partis regulated by a supporting bracketand disposed in the vehicle body.
