A body structure includes: a bumper beam extending in the vehicle width direction; a pair of front side frames separated from each other in the vehicle width direction; and a pair of bumper beam extensions provided between respective front ends of the pair of front side frames and the bumper beam. The bumper beam is connected to the pair of bumper beam extensions at positions lower than respective upper walls of the pair of front side frames; and each of front portions of the pair of bumper beam extensions includes a connection portion to which a rear wall of the bumper beam is connected, and an extension portion provided above the connection portion and extending toward the vehicle front above the bumper beam.

Vehicle body structure

The vehicle collision decision apparatus has first acceleration detectors and a second acceleration detector for detecting an acceleration of the vehicle in a longitudinal direction, and third acceleration detectors for detecting an acceleration of the vehicle in a transverse direction thereof. When the vehicle is involved in an offset collision, the front airbags of the vehicle are activated based on accelerations detected by the first acceleration detectors and the second acceleration detector. Thereafter, the curtain airbags of the vehicle are reliably activated.

Vehicle collision decision apparatus

Overlapping section () is constructed by positioning an inner side wall portion () of an outer impact absorbing section () closer to a longitudinal centerline () of a vehicle body than an outer side wall () of a front side frame (), so that a collision impact load can be transmitted to the outer side wall portion by way of the overlapping section. Inner impact absorbing section () projects forward by a greater length than an outer impact absorbing section (). Thus, an airbag-deploying acceleration threshold value Gs is set within a range between an acceleration level when the inner impact absorbing section () alone is deformed by impact energy and an acceleration level when the inner and outer impact absorbing sections () are deformed.

Vehicle front body structure

A sensor setup structure includes a pair of front side frames that are provided on vehicle widthwise opposite sides of a vehicle front part, and extended along a vehicle lengthwise direction, a pair of upper members that are provided to the vehicle widthwise outsides from these front side frames, and extended from respective front pillars on vehicle widthwise opposite sides downwards to the front, a joining frame that joins in the vehicle widthwise direction between the vicinity of front ends of these upper members and the front side frames on the same sides in the vehicle widthwise direction, and satellite sensors of an airbag apparatus which, in plan view, are setup in positions that are to the vehicle widthwise insides from vehicle widthwise outer surfaces of the respective upper members, and are to the vehicle widthwise outsides from vehicle widthwise outer surfaces of the respective front side frames.
