<p>A mechanism is provided for lowering the height of the front part of a motor vehicle. A radar sensor (10) is provided to sense the proximity of an adjacent vehicle. A signal is passed to a control unit (11) which responds when a potential accident situation is detected. An output (12) passes to a valve unit (21) which is actuated to permit gas from an inflatable element (19) to escape through a nozzle (22). As the gas escapes the element (19) reduces in length, and a lower housing element (18) connected to a wheel (16) of a vehicle moves upwardly into an upper housing element (17) which is fixed to part (14) of the structure of the vehicle. Thus the front part of the vehicle is lowered so that the bumper on the vehicle is at an appropriate height.</p> |
