Patent Images
1. A collision detection apparatus, comprising:
- a support member which is fixed to side members of a vehicle;
an absorber which is arranged at a vehicle front side of the support member to define a space therebetween;
a chamber member defining therein a chamber space which is substantially sealed, the chamber member being arranged in the space defined between the support member and the absorber; and
a pressure detection member for detecting a pressure in the chamber space, whereina collision of the vehicle is detected based on a variation in the pressure of the chamber space.

Abstract
A collision detection apparatus has a support member which is fixed to side members of a vehicle, an absorber which is arranged at a vehicle front side of the support member to define a space therebetween, a chamber member defining therein a chamber space which is substantially sealed, and a pressure sensor for detecting a pressure in the chamber space. The chamber member is arranged in the space defined between the absorber and the support member. A collision of the vehicle is detected based on a variation in the pressure of the chamber space.

13. A collision detection apparatus, comprising:
-
a first support member which is fixed to side members of a vehicle; an absorber functioning as a second support member which is arranged at a vehicle front side of the first support member to define a space therebetween; wherein the absorber and the first support member construct a substantially cylinder shape having two ends, at least one of which is open; a chamber member defining therein a chamber space which is substantially sealed, the chamber member being arranged in the space defined between the first support member and the second support member, wherein the chamber member is inserted in the space between the absorber and the first support member through the one end; and a pressure detection member for detecting a pressure in the chamber space, wherein a collision of the vehicle is detected based on a variation in the pressure of the chamber space. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
