Abstract
The invention concerns a procedure for selectively connecting a status detection device--from a group of such devices based on different physical action principles, in particular belt buckle status detection, and seat occupation detection, within a passive safety system for motor vehicles, in particular an airbag system, and/or a belt pretensioning system,--to the signal input of a control unit, using a single wire connection, by causing the control unit to activate an appropriate current/voltage supply in accordance with the physical action principle, and by appropriately processing the signals generated by the status detection device, which signals will then be fed to the control unit for evaluation. Furthermore, an interface circuit is specified for implementing the procedure according to the invention.
