Passive safety device release assembly for motor vehicle occupant - has acceleration pick=ups with sensitivity axes directed to detect angle of frontal impact and supplying evaluating circuit

摘要

The release device for a pressure safety restraint in a vehicle uses at least two acceleration sensors, each inserted in a respective measuring channel with an integrator and a threshold circuit. A logic module evaluates the signal characteristic and the signal flank characteritic to allow the integration constants of the integrators (14,15) to be varied and allow the evaluated range to be increased. ADVANTAGE - Allows adaptation to different vehicles.
