Abstract
A restraint system, in particular for a motor vehicle, includes a restraint device, to be activated in at least two steps; a sensor unit for sensing activation-relevant vehicle and operating data; a control device for processing the activation-relevant vehicle and operating data; as well as an ignition unit for driving the actuators for activating the at least one restraining device. To increase the safety of such a restraining device, at least two independently switched ignition units are provided such that, when one ignition unit fails, the activation of the restraint device in at least one step is guaranteed by the other ignition unit.
