<p>A vehicle seat (1) comprises a squab (3) and a backrest (2), with the backrest (2) being tiltable relative to the squab (3). A pulley wheel (21) is mounted to the backrest (2) and is connected to one end of an inner wire (22) of a Bowden cable (23). The Bowden cable (23) has an outer sheath (24) which is fixed relative to the squab (3). The other end of the inner wire (22) of the Bowden cable (23) is attached to an indicator element (26) and the indicator element (26) is moveable along a measurement unit (27). The measurement unit (27) is connected, via a processor (28), to a control unit (30) which controls an air-bag unit (29). If the backrest (2) is tilted rearwardly, the inner wire (22) is wound at least partly around the pulley wheel (21), pulling the indicator element (26) rearwardly along the measurement unit (27). The measurement unit (27) outputs a signal to the processor (28) and the processor (28) determines the distance between the backrest (2) and the air-bag unit (29) and provides a signal to the control unit (30) so that the control unit (30) may control the deployment of the air- bag unit (29) in dependence upon the distance between the backrest (2) and the air-bag unit (29).</p> |
