Abstract: A multi-purpose patient support and transport apparatus is provided which includes a Trendelenburg mechanism and a novel guard rail assembly. The Trendelenburg mechanism is actuated by turning a handle in one direction. This allows a penumatic spring connected between the seat and backrest assemblies to be fully contracted, thereby moving the backrest assembly to a Trendelenburg position. When the handle is turned in the opposite direction, the backrest may also be rotated downwardly, but is precluded from moving beyond the reclining position by a stop member which prevents the pneumatic spring shaft from moving entirely within the spring casing. The guard rail is mounted to the frame of the apparatus by a pair of pivot arms extending at an oblique angle with respect to the plane of the rail. This allows the rail to be stored under the frame when in the lowered position.

Abstract: A multi-purpose chair/stretcher assembly is disclosed which includes seat, backrest and leg supporting assemblies, the backrest and leg supporting assemblies both being pivotably mounted to the seat assembly. A pair of telescoping linkage assemblies connect the backrest and leg supporting assemblies so that the pivotal movement of one with respect to the other causes both to rotate in the same direction if restricted from telescoping. If this linkage assembly is allowed to telescope, the backrest assembly may be moved independently of the leg supporting assembly. A second linkage assembly connects the leg supporting assembly with the seat assembly. This second linkage assembly, while extendable and contractable, may be locked in a rigid configuration so that the leg supporting assembly may be held in a fixed position with respect to the seat assembly.
