  • Patent number: 6908133
    Abstract: A safety stop member which consists of an L-shaped member, plural fasteners for fastening a first leg of the L to the floor surface, a second leg of the L being oriented in an upstanding relation relative to the first leg and to the floor surface and configured so that the upstanding second leg will interfere with and engage a safety bar on an emergency cot only when the safety bar is positioned adjacent a juncture between the first and second legs. An outwardly facing side of the second leg is oriented generally flush with an edge of the access opening so that when the emergency cot extends outwardly from the access opening in the cargo area and the safety bar engages the second leg, the base on the emergency cot will be sufficiently spaced outwardly of an outermost facing surface of a step bumper on the emergency vehicle to facilitate an unobstructed deployment of the base to the deployed position thereof.
