Abstract

A vehicle body side structure includes: a side sill extending in a longitudinal direction of a vehicle at a side bottom of the vehicle and having a recess sagging inward in a width direction of the vehicle; a door being hollow, having a door bottom portion disposed so as to overlap the side sill when seen from a side, and being arranged at an outer side of the side sill in the width direction; and a force transferring member having a projection protruding inward in the width direction, being disposed in a hollow interior of the door bottom portion, and being configured to transfer force acting inward in the width direction to the side sill.

First claim

The invention claimed is:

1. A vehicle body side structure comprising:
a side sill extending in a longitudinal direction of a vehicle at a side bottom of the vehicle and having a recess extending in the longitudinal direction of the vehicle and sagging inward in a width direction of the vehicle and extending in the longitudinal direction;
a door being hollow, having a door bottom portion disposed so as to overlap the side sill when seen from a side, and being arranged at an outer side of the side sill in the width direction; and
a force transferring member having a projection protruding inward in the width direction, being disposed in a hollow interior of the door bottom portion, and being configured to transfer force acting inward in the width direction to the side sill,
wherein the recess receives the projection upon a side collision of the vehicle.

2. The vehicle body side structure according to claim 1 , wherein:
the side sill has a side face portion formed into a sheet shape on an outer side of the side sill in the width direction; and
the force transferring member is disposed so as to overlap the side face portion when seen from the side.

3. The vehicle body side structure according to claim 1 , wherein a vertical length of the projection is set shorter than a vertical length of the recess.

4. The vehicle body side structure according to claim 2 , wherein a vertical length of the projection is set shorter than a vertical length of the recess.

5. The vehicle body side structure according to claim 1 , wherein the projection is disposed below the recess.

6. The vehicle body side structure according to claim 2 , wherein the projection is disposed below the recess.

7. The vehicle body side structure according to claim 3 , wherein the projection is disposed below the recess.

8. The vehicle body side structure according to claim 1 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.

9. The vehicle body side structure according to claim 2 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.

10. The vehicle body side structure according to claim 3 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.

11. The vehicle body side structure according to claim 5 , wherein:
the side sill is bound together with a cross member extending in the width direction; and
the force transferring member is disposed so as to overlap the cross member when seen from the side.

12. The vehicle body side structure according to claim 1 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.

13. The vehicle body side structure according to claim 2 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.

14. The vehicle body side structure according to claim 3 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.

15. The vehicle body side structure according to claim 5 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.

16. The vehicle body side structure according to claim 8 , wherein the force transferring member extends between a rear end of the door bottom portion and a position at a front side of a seat installed in the vehicle.

17. The vehicle body side structure according to claim 1 , wherein the force transferring member forms a closed section in the hollow interior of the door bottom portion.

18. The vehicle body side structure according to claim 1 , wherein the force transferring member comprises a resin material formed by foam molding.

19. The vehicle body side structure according to claim 1 , wherein the force transferring member comprises a steel formed by bending.

20. The vehicle body side structure according to claim 1 , wherein the force transferring member is a solid member.
