Abstract

Information data and energy are transmitted from a central control to control modules through a bus system in an occupant protection system including occupant protection devices such as airbags. In order to avoid overloading the protection system due to an immediate recharging of an energy storage member after that member triggers an occupant protection device, such recharging is suppressed or interrupted, preferably until a reset command signal is received by the respective control module from the central control.
