Abstract
A hospital bed is provided with a safety mechanism for preventing the upper frame from moving with respect to the lower frame when an object or person is wedged therebetween. The safety mechanism includes an elongate detection device such as an air-tight, flexible tube or a ribbon switch. It is mounted to one of the frames so that a person wedged between the frames will contact it prior to incurring serious injury. The detection device is connected to a switch which deactuates the bed raising/lowering motor.
