Abstract
An energy supply device for an occupant protection system is described, including an ignition energy supply device and a back-up supply device, the ignition energy supply device including an ignition energy store, which is chargeable via a first charge circuit from a first system voltage to a reserve voltage, the ignition energy store being suitable for providing a high ignition energy in the range of 0.1 kW to 2.5 kW for at least one restraint means for a short time period of 0.5 ms to 2 ms. The back-up supply device includes a back-up energy store, which is chargeable via a second charge circuit from a system voltage to a back-up voltage, the back-up energy store having an energy density value higher than the ignition energy store by a factor of 10 to 50 and being suitable for providing the supply energy in the range of 1 W to 10 W for the passenger protection system in the event of a supply interruption for a predefined time period of at least 5 s.
