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.

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 pillar reinforcement of a center pillar comprises an upper part and a lower part with a boundary line of these parts being positioned below the middle level of the pillar reinforcement. The upper and lower parts respectively include side wall portions which extend along a vehicle side face and pairs of vertical wall portions which extend inwardly from front and rear end portions of the side wall portions. The pair of vertical wall portions of the lower part is slant relative to the vehicle width direction so that the distance between the vertical wall portions becomes wider toward the inward direction, and a slant angle of the pair of vertical wall portions of the lower part is greater than that of the vertical portions of the upper part.

Expansion of an air bag can be smoothly effected even in a small space by controlling the air bag in thickness and introduction of the gas for expansion, and the protection of an occupant can be rapidly implemented with a relatively small volume of the gas. An air bag device comprises a first air chamberfor protection of the chest or the waist of an occupant, a second air chamberfor protection of the head of the occupant, and a lower portion of the diffuser baginterposed therebetween for portioning out gas from an inflator, wherein the second air chamberhas a first tetherforming a gas passagefor guiding gas jetted from gas outlets of the lower portion of the diffuser baginto the second air chamberso as to go around the tether of a head protection region of an air bag, from the back side thereof toward the front side thereof, and has a second tetherfor forming a gap provided at the lower end of the first tetherin the vicinity of the gas outlets, for letting a portion of the gas escape into a front part of the second air chamber
