Title:
VEHICULAR COLLISION-SENSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/147546
Kind Code:
A1
Abstract:
This vehicular collision-sensing device has: a bumper absorber (2) positioned forward of a bumper reinforcement (9) within a bumper (7) of a vehicle; a detection tube member (3) having a hollow part (3a) formed in the interior thereof which is mounted in a groove (2c) that is formed in the bumper absorber and extends in the lateral direction; and a pressure sensor (4) for detecting the pressure inside the hollow part of the detection tube member. The vehicular collision sensing device senses collisions of objects with the bumper on the basis of the pressure detection results by the pressure sensor. The detection tube member is mounted in the groove part in a manner such that a first distance (La) from the front surface (2a) of the bumper absorber to the detection tube member differs by position in the lateral direction, and a second distance (Lb) from the rear surface (2b) of the bumper absorber to the detection tube member differs by position in the lateral direction.
