A vehicle braking arrangement includes a braking plate connected to a vehicle by a link arrangement. The braking plate is movable from a rest position to a braking position where contact is made with the ground, and includes a sealing rim arranged to at least partially contact the ground such that an at least partly enclosed volume is formed. The vehicle braking arrangement includes a low pressure container connected to the volume via a valve assembly. Air pressure in the low pressure container is below the air pressure of ambient air in the rest position of the braking plate. The valve assembly is arranged to be opened when the braking plate is in the braking position such that the pressure is lowered in the volume and the braking plate is pressed against the ground by a conferred pressure difference between air outside the volume and air in the volume.

Vehicle low pressure brake arrangement

A vehicle seat has a back-rest () carrying a head-rest (). A mechanism is provided to move the head-rest () forwardly relative to the back-rest () in response to a rear impact situation. An element () is operatively located between the head-rest () and the mechanism () which is adapted to yield when exposed to a force in excess of a predetermined force. Thus the force that can be applied by the head-rest () to a head () of an occupant of the seat, is limited to be a maximum of 200 Newtons, with the preferred value being 100 Newtons.

A mechanism is provided for lowering the height of the front part of a motor vehicle. A radar sensor is provided to sense the proximity of an adjacent vehicle. A signal is passed to a control unit which responds when a potential accident situation is detected. An output passes to a valve unit which is actuated to permit gas from an inflatable element to escape through a nozzle. As the gas escapes the element reduces in length, and a lowering housing element connected to a wheel of a vehicle moves upwardly into an upper housing element which is fixed to part 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.
