IMPACT DETECTION STRUCTURE, IMPACT DETECTION SYSTEM AND METHOD, AND OCCUPANT PROTECTION SYSTEM AND METHOD

摘要

The side impact detection system (12) includes a two-stage load transmitting structure (22) that transmits to a floor tunnel, in which a side impact-detecting G sensor is provided, load caused by a side impact at a predetermined impact speed Vp in two stages having a predetermined time lag in such a manner that the load transmitted or the rate of change in the load differs between the first-stage load transmission and the second-stage load transmission.
