ABSTRACT:
An adjustable bed allowing the knee portion to automatically rise upon the elevating of the head portion. Alternately, when desired, the knee may remain flat while the head of the bed elevates. The mechanism elevating the knee connects to the structure which effecuates the raising of the head. This mechanism occupies one position when the knee accompanies the head portion in rising and a second position when the knee remains flat. Conveniently, this mechanism consists of a cam connected to the member elevating the head portion. The cam occupies a position where it contacts a cam follower on the knee portion of the bed when the knee rises and a second position where it does not contact the cam follower for the instance where the knee remains flat. These two positions of the cam may have rotational or translational separation from each other.
