A triggering unit is disclosed for use in triggering a safety device in a motor vehicle to protect an occupant of the vehicle in an impact situation in which the vehicle impacts with an impacting object. The triggering unit is configured to actuate the safety device only for total stiffness between the vehicle and the impacting object exceeds a predetermined stiffness value. The unit incorporates a calculating arrangement to calculate stiffness from two or more sensed parameters.
