a sensor unit for sensing activation-relevant operating data and providing the activation-relevant operating data to the control
device; and
at least two independently switched ignition units coupled with the control device and to each of the at least two restraint
devices, wherein the at least two independently switched ignition units are operably configured such that, if one ignition
units fails, activation of each of the at least two restraint devices in at least one stage is performed by the other ignition
unit, wherein
each of the at least two ignition units includes two ignition end stages, the two ignition end stages of each of the at least
