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).

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 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.

An impact bar includes a U-shaped portion formed by a vertical face portion and upper-and-lower lateral face portions at its front end. The impact bar further includes upper-and-lower outer face portions. A pair of first joint portions which are formed so as to extend upward and downward from respective front ends of the upper-and-lower lateral face portions are joined to a lateral face portion of a door inner panel. A pair of second joint portions which are formed so as to extend forward from respective front ends of the upper-and-lower outer face portions are joined to a longitudinal face portion of the door inner panel.

Door structure of vehicle

A pair of right-and-left roof rails, a roof panel provided between the roof rails, a roof reinforcement extending in a vehicle width direction below the roof panel, a center pillar, and a gusset joined to an end portion, in the vehicle width direction, of the roof reinforcement are provided. Further, a node-shaped plate member is provided inside the roof rail at a position which overlaps the roof reinforcement longitudinally and vertically. Accordingly, buckling of a portion of the roof reinforcement which is located in the vicinity of a roof side can be restrained.

Upper vehicle-body structure of vehicle

A load transmitting member comprising a rising face portion rising from a floor panel and a facing face portion facing a portion of the side panel between a rear edge portion of a rear-door opening portion and a rear-wheel house portion and having its short longitudinal width is arranged on an inward side of a side panel. The load transmitting member is fixed to a front portion of the rear-wheel house portion directly or via a bracket. The load transmitting member can be arranged so as not to prevent a smooth ingress/egress action of a passenger, and a proper load-transmission function of the load transmission member when the impact load is inputted to a rear door from the vehicle side can be attained so as to effectively restrain the rear door from coming into a vehicle compartment.

Side vehicle-body structure of vehicle

At an upper part of a center pillar, a length Lof a covering portion of a pillar inner panel is set to be substantially equal to a distance Lbetween a pair of flange-ridgeline portions of a pillar reinforcement. Meanwhile, at a lower part of the center pillar, a length Lof a covering portion of the pillar inner panel is set to be longer than a distance Lbetween a pair of flange-ridgeline portions of the pillar reinforcement. Accordingly, a vehicle-body structure of a vehicle which can secure the proper absorption function of the vehicle collision load with cooperation of the first and second members can be provided.

A reinforcing member is provided at a lower-outside corner of a side-sill reinforcement so as to extend in the vehicle longitudinal direction including a connection portion of the side sill to a center pillar for straining deformation of the corner. A deformation promoting portion which is provided at an upper portion of the side-sill reinforcement at a specified position which corresponds to the connection portion for prompting deformation of the upper portion of the side-sill reinforcement. Accordingly, a lower vehicle-body structure of a vehicle which can properly restrain the side sill and the center pillar from coming toward the vehicle inside at the vehicle side crash can be provided.
