Abstract: An automobile vehicle compartment includes an octagonal frame having side sills that extend in the vehicle body fore-and-aft direction, a dashboard lower cross member and middle cross member that extend in the vehicle width direction, and four inclined members, and it is therefore possible to ensure that there is sufficient rigidity both for a collision load from the vehicle body fore-and-aft direction and from the side of the vehicle body, thereby minimizing deformation of the vehicle compartment. Furthermore, since front side frames and a front bumper beam form a U-shaped frame that curves in a U-shape toward the vehicle body fore-and-aft direction in front of the vehicle compartment, it is possible by crushing of the high rigidity U-shaped frame to absorb effectively a collision load from the vehicle body fore-and-aft direction, including an offset collision, thereby preventing more effectively deformation of the vehicle compartment.

Abstract: Overlapping section (81) is constructed by positioning an inner side wall portion (78) of an outer impact absorbing section (63) closer to a longitudinal centerline (48) of a vehicle body than an outer side wall (33, 103) of a front side frame (11, 12; 91), so that a collision impact load can be transmitted to the outer side wall portion by way of the overlapping section.

Thus, an airbag-deploying acceleration threshold value Gs is set within a range between an acceleration level when the inner impact absorbing section (62) alone is deformed by impact energy and an acceleration level when the inner and outer impact absorbing sections (62, 63) are deformed.
