ABSTRACT:
An adjustable bed includes a patient operated linear positioner, a rail assembly and a leg lift mechanism. The patient operated linear positioner includes a subassembly with a bellcrank which pivots by a patient operated soft strap. When the strap is pulled, the bellcrank pushes a cable inward which, in turn, releases a positioner rod so that the bed may be adjusted. The side rail assembly includes a J-shaped attachment bar and an idler link which acts to move the side rail both upward and forward when the head section of the adjustable bed is raised. A bed side rail may be attached to a bed frame through the use of a unique attachment mechanism which requires no tools. A further aspect of the invention utilizes a scissors-type leg lifting mechanism for holding and controlling the rate of collapsing movement of the foot section of a bed mattress frame. The leg lifting mechanism includes a mechanical lock and gas piston subassembly.
