摘要

A sensor 10 for activating a passenger restraint system 140 in a motor vehicle includes a housing 12 with a passage 14 for defining a path of movement, and an inertial element 18 moving in that path. A mechanical member 18 (or a magnetic member 134) is used to bias the inertial element 16 (or 118) toward a preset position. The preset position is defined by a presetting member 22 which is adjustable so that the accelerometer is responsive to crashes with a tolerance of +/- 0.5 m/s. As the inertial element moves away from the preset position in a crash, it closes an electrical contact 18 and 20 for deploying the passenger restraint system.
