## Abstract

A body stopper for a vehicle includes stopper members secured to frame members of the vehicle, and gussets secured to a floor panel at the bottom of the vehicle cabin. Each gusset has its upper surface secured to the floor panel at a position corresponding to a seat cross member and its side surface secured to a side sill under a door of the body. Each gusset is formed to provide a closed cross section in cooperation with the floor panel. Stopper members are welded to the frame members at positions in front of the gussets, and each stopper member is formed to provide a closed cross section in cooperation with the associated frame member. A rearward impact to the front face of the vehicle is quickly transmitted from the frame members to the body due to reliable engagement between the gussets and the stopper members. The gussets used as elements of the body stopper also increase the rigidity of the body.

## Claims

### Claim 1

A body stopper structure for a vehicle including a pair of frame members extending in the lengthwise direction of the vehicle, a body supported on the frame members, a floor panel forming a floor of the body, a seat cross member provided on the floor panel and adapted to be positioned under front seats in a cabin of the vehicle, and side sills extending along both sides of the floor panel, said body stopper structure comprising:
a plurality of gussets, each gusset secured both to a lower surface of the floor panel and to one of the side sills at a position corresponding to the seat cross member on the floor panel, and each gusset configured to have a closed cross section in cooperation with the floor panel; and
a plurality of stopper members each stopper member secured to one of the frame members at a distance from the front end of one of the gussets, and each stopper member configured to have a closed cross section in cooperation with the associated frame member.
