Abstract

A device for actuating a safety device, in particular a roll bar in a motor vehicle. The device includes a first sensor which is actuated when a vehicle acceleration exceeding a predetermined limiting value occurs and which generates a switch signal for a release device to activate the roll bar. The device also includes second and third sensors which control switches when both at least one wheel suspension is fully extended and the vehicle is tilted about either a longitudinal or transverse axis, so as to actuate the safety device during even relatively slow overturns.
