Abstract
The invention relates to a safety system for motor-vehicle occupants, in particular a restraint system, such as an airbag, belt tighteners, etc., which has at least one tripping sensor that exhibits a response time, one processing unit, and one final firing stage for activating the safety system. To protect against spurious tripping, an inhibiting circuit (21) is proposed, which is triggered by the processing unit (2). It cancels an interlock of the final firing stage (5) only after an interlocking enable time (t.sub.v) has elapsed, whereby the interlocking enable time (t.sub.v) is shorter than the response time (t.sub.a) of the tripping sensor (1).
Claims22
A safety system for controlling a motor-vehicle restraint system, comprising:
- at least one tripping sensor which exhibits a response time;
- at least one processing unit coupled to the tripping sensor;
- at least one final firing stage for activating the restraint system;
- and
- an inhibiting circuit controllable by the processing unit, wherein the inhibiting circuit cancels an interlock of the final firing stage only after an interlocking enable time has elapsed, the interlocking enable time being shorter than the response time of the tripping sensor.
A system for controlling a restraint device in a motor vehicle, comprising:
- a firing stage for activating the restraint device;
- a sensor having a response time;
- means for interlocking the firing state to prevent an activation of the restraint device;
- an inhibiting circuit for canceling an interlock of the firing stage within a predetermined period of time shorter than the response time of the sensor;
- and
- a processing unit coupled to an output of the sensor for controlling the inhibiting circuit and triggering the firing stage.
