The driver's cab (1) on a HGV (Heavy Goods Vehicle 10) has frangible mountings (1.1,1.2) on its underside attached to the chassis frame (3). A cable (5.2) is attached (8.2) to the front or bottom of the cab. The cable passes over a pulley (6) on the front of the chassis frame and is connected (7.2) to a tension spring (5.1). If the cab impacts on a vehicle (9) in front, it is driven backwards on the chassis in a controlled fashion to reduce the shock loading on the driver. |
