Restraint system especially for an occupant of a vehicle

A restraint system for occupants of a vehicle, said restraint system comprising

• at least one restraint device (R1, R2, . . . , Rk) for holding-back or restraining at least one occupant of said vehicle;
• at least one seat position sensor (SPS1, SPS2, . . . , SPSm), said at least one seat position sensor including means for determining a change in a seat position of said at least one occupant of said vehicle;
• at least one precrash sensor (PCS1, PCS2, . . . , PCSn) for generating at least one precrash signal indicative of an incipient collision;
• and
• a control unit (SE) including
• means for forming a first criterion for tripping said at least one restraint device if a rate of change of said seat position of said at least one occupant exceeds a predetermined threshold;
• means for forming a second criterion for tripping said at least one restraint device if said at least one precrash sensor generates a precrash sensor signal indicative of said incipient collision;
• and
• means for tripping said at least one restraint device if and only if both of said tripping criteria are simultaneously satisfied and a braking datum is present.
