Abstract

The impact absorbing support for a car seat has a pneumatic bellows(5) mounted inside the squab(1) to compress with the suspension movements. The bellows is fitted with flow restriction valves so that sudden impacts are supported. The bellows provide a soft suspension with a firm support for impact forces, without the seat occupant dipping out of the safety belt. The bellows is mounted centrally under the seat, with the larger fold structure at the front edge of the seat.
