To suppress damage on a bonnet at light collision, a vehicle-body structure includes rear-portion crush cans that perform compressive deformation when a first predetermined load is applied, and front-portion crush cans that perform compressive deformation when a second predetermined load smaller than the first predetermined load is applied. A front portion of a bonnet is positioned on a vehicle rear side of front portions of the rear-portion crush cans.

Vehicle-body structure that supresses damage from a collision

To suppress deformation of a vehicle cabin by efficiently absorbing an impact load obliquely from a vehicle front side, a vehicle-body front structure includes an upper-side cross member, a lower-side cross member, upper-side impact absorption members that support respective ones of both vehicle-width-direction sides of the upper-side cross member, and lower-side impact absorption members that support respective ones of both vehicle-width-direction sides of the lower-side cross member. The upper-side impact absorption members and the lower-side impact absorption members are each positioned farther on a vehicle-width-direction outer side at a position farther on a vehicle front side.

Vehicle-body front structure that suppresses deformation of a vehicle cabin

There are provided an outer panel, an inner panel, a second reinforcement provided in the main closed-cross section and cooperates with the outer panel to form a sub closed-cross section extending longitudinally, a bead portion formed at a portion of the inner panel which is located at a position corresponding to the second reinforcement, and configured to be a starting point causing bending of a front side frame toward the second reinforcement when a collision load is applied in a vehicle collision, and a second attaching member provided at a position located on a front-end side of the front side frame relatively to the second reinforcement and configured to make the second reinforcement crushable in a bending direction in the vehicle collision. The second attaching member comprises a knot-shaped member provided inside the main closed-cross section.

Frame structure for 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.

Vehicle-body structure of vehicle

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.

Lower vehicle-body structure of vehicle

A door trim covers a door body of a side door. An article storage portion is provided at a lower portion of the door trim. A seat is provided beside the side door so that the seat and the side door are overlapped when viewed from a vehicle side. A side airbag device includes an airbag which inflates beside the seat with gas supplied from an inflator at a vehicle side crash and protects chest and waist portions of a passenger. A recess is provided at the door trim. The recess is concaved toward a vehicle outside at an upper portion of the door trim above the article storage portion. A covering member which restrains the airbag from coming into the recess is provided at the door trim so as to cover almost half of the recess.

Interior structure of vehicle

A side airbag device provided at a seat back of a seat, comprises an airbag including a chest-abdomen protection portion to protect a chest and abdomen of an occupant seated and a waist protection portion to protect a waist of the occupant, and an inflator to supply gas to the airbag for an inflation at a vehicle side crash or a vehicle turnover, wherein the portions are partitioned by a partition portion that at least extends substantially rearward from an front edge of the airbag, and a recess is provided at an upper portion of the chest-abdomen protection portion. Accordingly, a whole part of side body including the chest, abdomen and waist can be properly protected regardless of the body size of the occupant, even for the occupant having the relatively small body size.
