STARTING GEAR FOR OCCUPANT PROTECTION APPARATUS

摘要

A starting gear for occupant protection apparatus, comprising angular velocity or acceleration sensor (11) for detection of the behavior of vehicle; arithmetic processing sections (131, 132) for performing two or more varieties of arithmetical operations being different in subtraction quantity as to physical quantity based on an output from the sensor (11); comparison section (133) for comparing the absolute values of respective outputs from the arithmetic processing sections (131, 132) with each other; selection section (134) for selecting the output value from arithmetic processing sections (131, 132) providing the minimum absolute value; and judgment section (135) for judging whether starting of the occupant protection apparatus is needed or not on the basis of the selected output value.
