<p>Device for the detection of the presence of a driver at the driver's seat (1) in a vehicle, for a trip by land, sea or in the air, comprising at least one sensor (4) is described. It is characterised primarily in that this sensor (4) is arranged to measure continuously frequency and amplitude of the vibration of the driver's seat in both directions of the horizontal plane. The device comprises means (5) for the continuous registration of the damping, i.e., the amplitude, which damping forms an indication of the presence of a driver.</p> |
