Abstract
A surface foot section is provided for a bed which includes a base frame and an articulating deck coupled to the base frame. The articulating deck includes a generally planar foot deck section and is movable from a bed configuration to a chair configuration. A foot section control module is provided to deflate the surface foot section when the articulating deck is in the chair configuration and to inflate the surface foot section when the articulating deck is in the bed configuration. The surface foot section includes a first air bladder configured to collapse in a first direction generally parallel to the foot deck section when the first air bladder is deflated, and a second air bladder located adjacent the first air bladder. The second air bladder is configured to collapse in a second direction normal to the foot deck section when the second air bladder is deflated so that the surface foot section has a substantially reduced thickness and a substantially reduced length when the first and second bladders are deflated.
