Abstract

A safety system for a vehicle is provided, which comprises signalling means associated with a seat of the vehicle for emitting an optically detectable signal carrying information related to the seat and detecting means for remotely detecting the optically detectable signal and for providing a corresponding signal to a control unit.

Claims

1. A safety system for a vehicle comprising a sensing device associated with a vehicle seat, said sensing device for detecting a status related to said vehicle seat;

signalling means associated with said vehicle seat, said signalling means being responsive to said sensing device for emitting an optically detectable signal carrying information related to the status detected by said sensing device; and

detecting means arranged for remotely detecting said optically detectable signal and for providing a corresponding signal to a control unit.

2. A safety system according to claim 1, wherein said sensing device is chosen from a group comprising seat belt buckle detector, passenger presence detector, child restraint system detector and folded-seat detector, said information being related to a status detected by said sensing device.

3. A safety system according to claim 1, wherein said detecting means comprises a camera which is arranged within said vehicle so that a field of vision of said camera covers a region containing said signalling means.

4. A safety system according to claim 1, wherein said detecting means comprises a photoelectric cell or a photodiode.

5. A safety system according to claim 1, wherein said signalling means comprises a light emitting device.

6. A safety system according to claim 1, further comprising additional detecting means associated with said seat and additional signalling means arranged within said vehicle, so as to enable bi-directional communication.

7. A safety system according to claim 6, wherein the operation of said signalling means is initiated by a signal emitted by said additional signalling means and received by said additional detecting means.

8. A safety system according to claim 1, wherein said signalling means is powered by collecting light energy.
