Abstract
A restraint system is disclosed which with high reliability trips one or more restraint devices, if in a collision there is the risk of injury to vehicle occupants. This restraint system is equipped with at least one seat position senor (SPS1, SPS2, . . . , SPSm), with which a change in the seat position of at least one vehicle occupant can be ascertained, and a control unit (SE) forms a first criterion for tripping one or more restraint devices (R1, R2, . . . , Rk) if the rate of change of the seat position exceeds a predeterminable threshold. The control unit (SE) forms a second criterion for tripping one or more restraint devices (R1, R2, . . . , Rk) if one or more precrash sensors (PCS1, PCS2, . . . , PCSn) signal an incipient collision. The control unit (SE) does not cause the tripping of one or more restraint devices (R1, R2, . . . , Rk) unless both tripping criteria are satisfied and also a braking datum (BI), advantageously generated by a brake light switch, is present.
