PROBLEM TO BE SOLVED: To provide a collision detecting means capable of detecting the collision of a pedestrian against the bumper of a vehicle. SOLUTION: This collision detecting means is provided with a backboard 1, chamber members 2 demarcating a chamber space 20, and pressure sensors 3, and it detects the collision based on a change in the pressure of the chamber space 20. A plurality of the chamber members 2, 2, 2, having the pressure sensors 3 respectively are arranged side by side in the width direction of the vehicle. In this collision detecting means, the collapse characteristics of the chamber members 2 are adjusted to control the pressure change due to the deformation of the chamber members 2. Thus, the collision detecting means superior in detection accuracy is achieved. COPYRIGHT: (C)2008,JPO&INPIT
