  • Safety latches for side rails and back rests of hospital stretchers
    Patent number: 4584728
    Abstract: The frame of the litter top has side rails swingably connected to the sides of the frame, and a head and back rest pivoted transversely of the frame at one end. Spring pressed latches between the side rails and the frame and between the back rest and the frame have release members which are accessible and operable only from the exterior of the litter, and which cannot be actuated when pressure is applied by the patient against the inside of the rails or the top of the back rest; thus preventing accidental or unattended lowering of these parts.
