Abstract
A circuit arrangement, attainable with simple switching means, for measuring decelerations of a vehicle that, caused by a braking operation occurring before a crash, lead to a change in the seat position of the vehicle occupants, comprises measuring the deceleration with an acceleration sensor (BS), which is designed to detect high decelerations occurring in a crash, and the presence of an amplifier (OP), which amplifies the output voltage (UO) of the sensor (BS), ascribed to low decelerations, so that the digital measurement signal (MS) derived from the amplified output voltage (UOV) by an analog/digital converter (AD) has adequately high resolution of the decelerations.
