SUPPORT MEMBER, DETECTION UNIT, SIDE SURFACE COLLISION DETECTION SYSTEM, AND OCCUPANT RESTRAINT SYSTEM

摘要

An acceleration sensor (40R) for detecting a side surface collision which occurs in a vehicle is mounted on a beam (112) of a door via a support member (50). If a force due to a collision acts on the beam (112), this force is transmitted to the acceleration sensor (40R) after being damped by the support member (50). As a consequence of the above, even if the beam (112) moves at an acceleration exceeding the rated input of the acceleration sensor (40R), the acceleration of the acceleration sensor (40R) is constrained to a level not higher than the rated input. Therefore, the side surface collision can be detected with high accuracy without using a sensor having a high rated input.
