ABSTRACT:
By providing position control means cooperatively associated with a support pad with said control means being constructed for arcuately moving the support pad in response to activation by the user, with the position control means and pad peripherally surrounded by a cover, a unique, portable, self-contained, unitary, movably adjustable support assembly is attained whereby individuals are able to position the support pad in any desired location or on any surface while also being able to automatically raise and/or lower the support pad to any position for comfort and support. In the preferred embodiment, the movably adjustable support assembly is constructed with expandable shroud means integrally connected with the cover in association with the position control means for expanding in response to the arcuate movement of the position control means while being automatically retracted into a folded configuration when the control means are returned to its original position. In addition, the present invention incorporates a single air flow control assembly which is capable of directly controlling two separate and independent movably adjustable support assemblies, each of which employ separate control means. In this way, individuals with queen or king sized beds are able to employ two separate and independent movably adjustable support assemblies on the single bed for separate and independent control, while employing a single air flow control assembly.
