Abstract: At the time of head-on collision of a vehicle, an intermediate portion of a subframe 6 is folded and deformed downwardly into a form of L-shape, an engine body 8 is moved downward, a radiator core upper rail 11 is rearwardly deformed and moved, a collision load is input to an upper portion of the engine body 8 through a rod 10, and the engine body 8 is rotated rearward around a connecting member 9. With this, a distance of a shortest portion between the engine body 8 and a dash panel 3 is increased, and a crushing stroke of the engine room 1 is increased.

Abstract: A side structure is provided to restrict the rotation of a seat when a side impact is exerted on a vehicle body. In order to reinforce the passenger's seat 7 in a vehicle's width direction, the side structure includes a load-direction converting member 24 arranged in the passenger's seat 7 to extend in the vehicle's width direction. A center pillar 1 has an engagement member 25 attached to an inner pillar member 12. When a side impact is applied on the vehicle body, the engagement member 25 engages with an outermost end 24a of the member 24 to prevent the passenger's seat from rotating.

Abstract: A vehicle body structure is provided to ensure a sufficient space in a passenger's room of a vehicle and bear an impact load inputted to the vehicle's part higher than a floor tunnel. The vehicle body structure includes a center pillar 1, a front door, a rear door, a floor panel 4 arranged at the bottom of the passenger's room, a floor tunnel 5 formed to project upward at the center of the floor panel 4 of the vehicle's width direction and also extend in the fore-and-aft direction of the vehicle body, and a passenger's seat 7 arranged on the floor panel 4. The structure further includes a load-direction converting member 28 for transmitting the impact load toward the floor tunnel 5. The load-direction converting member 28 is formed with a lower frame 21a of a seat back frame 21 as the framework of the passenger's seat 7.
