VEHICLE IMPACT DETECTION SYSTEM
First Claim
1. A vehicle impact detection system comprising:
- a pair of right and left side sills that form a closed cross section structure, extend in a vehicle front-rear direction, and are arranged parallel with a lower side part of a vehicle body;
a first cross member whose ends are joined to inner surfaces of the side sills in a vehicle-width direction;
a second cross member that is arranged behind the first cross member in the vehicle front-rear direction and whose ends are joined to inner surfaces of the side sills in the vehicle-width direction;
a floor tunnel extending in the vehicle front-rear direction and joined to the first and second cross members in a substantially central section in the vehicle-width direction;
a load-transmitting member that has a shape like an arch curved outwards in the vehicle width direction, is installed in each of the side sills, and is joined to the corresponding side sill from the inside of the side sill at positions corresponding to joining areas with the side sill and the first and second cross members;
a first impact detection element that is disposed near the joining areas with the side sill and the first and second cross members, and detects an impact from the outside in the vehicle-width direction; and
a second impact detection element that is disposed in the floor tunnel to be offset from the first impact detection element in the vehicle front-rear direction, and detects an impact from the outside in the vehicle-width direction.

Abstract
A side sill beam having a shape of an arch concave outwards in a vehicle-width direction is placed in a side sill, and includes first and second ends welded to joining areas with front and rear floor cross members, respectively. A first impact detection element that detects an impact from the outside in the vehicle-width direction is disposed near the joining areas of the side sill and the front or rear floor cross member, and a second impact detection element that detects an impact from the outside in the vehicle-width direction is disposed offset from the first impact detection element in a vehicle front-rear direction as viewed in the vehicle-width direction.
