Seatbelt safety device for vehicle, especially motor vehicle, has sensor that detects movement of inertial mass, passes corresponding signal to evaluation unit that determines degree of accident severity

摘要

The device (2) has an inertial mass (4) in an accommodation chamber movable relative to the vehicle body, especially under accident related braking deceleration, to activate at least one restraining system (9) in the vehicle interior. A sensor (6) detects movement of the inertial mass and passes a corresponding signal to an evaluation unit (7) that determines the degree of severity of the accident, upon which the activation decision depends.
