ABSTRACT:
A safety seat installed in a motor vehicle includes a safety belt, a movable seat and sensors. The movable seat is supported on pipe rails by ball rollers and is locked by a locking device controlled by electromagnetic force. The sensor has two metal elements which are separated from each other. When the motor vehicle collides with an obstruction the two metal elements contact each other and close an electric circuit whereby the locking device will release the seat under the action of an electromagnetic force. The seat is forced to move backward by the action of compressed springs, to prevent the driver and/or passenger on the front seat from being injured by damaging objects penetrating into the cab and/or the front seat.
