<P>PROBLEM TO BE SOLVED: To provide a collision detection structure capable of differing the load transmission mode to an acceleration detection unit between a case of a collision and other cases, and to provide an occupant protection system having the collision detection structure to adequately protect an occupant. <P>SOLUTION: A side impact detection system 10 has a two-stage load transmitting structure 22 that transmits to a floor tunnel, in which a side impact-detecting G sensor is provided, the load caused by a side impact at a predetermined impact speed Vp in first and second stages having a predetermined time lag in such a manner that the load or the rate of the load change differs between the first-stage load transmission and the second-stage load transmission. <P>COPYRIGHT: (C)2010,JPO&INPIT |
