In a system having a control unit for triggering a restraint system for
vehicles, and having a status acquisition device, such as a seat
occupation device, from which a data record describing the presence or
the non-presence of the condition is transmitted to the control device,
upon a defined stimulation signal from the control unit to the status
acquisition device the latter transmits a second data record to the
control unit, which corresponds to the type characteristics and the type
data. Thereby, type data are able to be recorded even in the case of a
status acquisition device installed in an obstructed way in a motor
vehicle.
