An opening portion is formed at a specified portion of a roof gusset which covers part of a panel joint portion from below. A pair of center-pillar side joint portions is provided at an outward end portion of the roof gusset, which is joined to a center pillar directly or via another panel member. A pair of first high-rigidity portions is provided at specified portions of the roof gusset which overlap the opening portion in a vehicle width direction and overlap the center-pillar joint portions in the vehicle longitudinal direction, respectively. A second high-rigidity portion is provided at an inward end portion of the roof gusset to extend in the vehicle longitudinal direction.

Upper vehicle-body structure of vehicle

A center pillar includes a first reinforcement panel which is arranged between an outer panel and an inner panel, comprises a bottom wall portion, both-side vertical wall portions extending in a vehicle width direction from the bottom wall portion, and both-side flange portions, and has a cross section formed in substantially a hat shape. A second reinforcement panel comprising a bottom wall portion and both-side vertical wall portions and having a cross section formed in substantially a U shape is arranged inside the first reinforcement panel. The second reinforcement panel is joined to the first reinforcement panel such that only the bottom wall portion and one of the both-side vertical wall portions are joined to the bottom wall portion and one of the both-side vertical wall portions, respectively.

Vehicle-body side portion 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.

Side airbag device

A ring portion of a steering wheel is disposed to be inclined relative to a vertical direction with an inclined angle between 40 and 90 degrees, when viewed from a vehicle width direction, and a bag portion has a larger configuration than the ring portion so as to cover over the ring portion when an airbag inflation is completed. Accordingly, there can be provided the steering wheel equipped with the so-called donut type of airbag portion of a airbag device that can perform its advantages fully and thereby improve the driver's protection.

Steering wheel equipped with airbag device

In a vehicle seat system equipped with an active headrest mechanism () and a lumbar support (), a load-receiving part () of the active headrest mechanism () is positioned behind the lumbar support () as viewed from front of the seat. The vehicle seat system is arranged so that when a specified amount or more of load is applied from front of the seat to a lumbar support plate () of the lumbar support (), one end part of a plate support member () supporting the lumbar support plate () exits from an insertion hole () provided at a side frame () to disengage from a seatback frame (), and the disengaged end part of the plate support member () then abuts on the load-receiving part ().
