MODULE FOR DETECTING VEHICULAR CRASH AND A VEHICULAR AIRBAG DEPLOYING SYSTEM COMPRISING THE SAME

摘要

A vehicle crash detection module and a vehicle airbag inflation system having the same are provided to allow a driver to quickly recognize vehicle crash by sequentially detecting stress wave transmitted through a frame member of a vehicle in the case of a collision. A vehicle crash detection module comprises a load member being in contact with a frame member of a vehicle, a plurality of sensors, a housing and a bias member(140). The sensors are mounted on the load member lengthwise along the load member to detect stress wave transferred through the load member. The housing supports the load member and is mounted on the frame member so that one end of the load member is in contact with the frame member at one end of the housing. The bias member is disposed between the other end of the load member of the other end of the housing to bias the load member toward the frame member. The load member includes a first load(221) and a second load(222). The sensor includes a first sensor(131) and a second sensor(132).
