  • Patent number: 5528783
    Abstract: A device for the positioning and support of the head or the head and torso of a person in a supine or reclined position. This device consists of a wedge shaped inflatable air bladder, a source of pressurized air, and air hose and valves for the controlled inflation and deflation of the air bladder. The air bladder is preferably constructed of heavy duty rubber or other resilient material and has joints of soft rubber or other soft resilient material along the front and back edges of the base, along the apex, and along the middle of the back wall of the air bladder, to provide for the predictable and compact folding of the air bladder in deflation. There is also a sheet of resilient material extending forward from the base of the air bladder, upon which the user's weight is superimposed during use, thereby preventing the device from slipping away from the user.

  • Patent number: 5497520
    Abstract: An inflatable support for selectively supporting a persons's feet and legs comprises an air bag having a semi-tubular top panel, an essentially flat bottom panel, and side panels that are "hinged" together at collapse joints in a manner to fold together to permit the top panel to collapse downwardly against the bottom panel. The side panels fold inwardly toward one another in an accordion-like fashion to permit essentially full collapse of the foot and leg support to a thickness of only that of the combined thicknesses of rubber material, of which the support is constructed. A remote compressed air source communicates with an inflation valve to inflate the foot and leg support, and a second deflation valve exhausts the pressurized air within the air bag to atmosphere. A remote control unit permits the user to activate the inflation and deflation valves to inflate/deflate the air bag to raise/lower the user's feet and legs as desired.
