ABSTRACT:
A compressive bumper assembly is disclosed for an electrically powered vehicle in which a bumper is resiliently supported in spaced relationship from the vehicle proper by means of a plurality of springs. The maximum displacement of the bumper from the vehicle is defined by means of inextensible members such as cables, chains or the like, which are secured to the bumper and to the vehicle. Levers are attached to the bumper at one end, the other ends having cam surfaces and being pivotally supported on the vehicle. Switches, electrically in series with the power supply for the vehicle, are provided with followers which are placed contiguously with the cam surfaces on the levers. The position of each follower determines the closed or open position of the associated switch. When the bumper comes in contact with personnel or any object, the bumper is compressed and the follower disciplined by the cam surface is displaced to open the proximate switch.
