Abstract:

An adjustable bed is shown having an adjustable frame which supports an articulated mattress. The frame mounts a single motor which lifts a first adjustable section thereof through a threaded drive shaft. A push linkage connects from the first adjustable section of the frame back to the frame itself where a conversion plate connects the push linkage to a pull linkage. The pull linkage connects to a second adjustable section of the frame. The single motor thus raises the first adjustable section and, through the linkage, the second adjustable section.
