Abstract: An improved waterbed having a waterbed mattress and a bed protecting cover with airbag protecting sides. The waterbed mattress has a plurality of internal, transverse partitions welded by high-frequency heat sealing, arranged at intervals in single or double rows, with water openings. When the water is filled and the air is inflated, the partitions buffer the water forces to increase the stability and maintain the bed mattress firm, straight and in shape. The level of compressing force towards the waterbed mattress can be changed by increasing or decreasing the air pressure in the airbag protecting sides to adjust the softness and hardness of the waterbed mattress.

Abstract: Fluid-filled, flexible-walled chambers in a variety of shapes are embraceably fitted with elastic loops or girths whereby the overall resiliency and cushioning ability of the chambers is improved. The expanded versatility of the resilient chambers makes possible improved designs of airbed and waterbed mattresses, and of toys, sports and safety equipment.A method for controlling and improving the impact between automobile safety airbags and auto passengers is made possible through the incorporation of elastic girths in the design of the airbag.

Abstract: An improvement for a water bed includes a pair of water bed mattresses housed in a bed cover. There is a heat insulating foam or air bag sandwiched between the two water bed mattresses. Each water bed mattress has a plurality of transverse partitions to reduce water vibration and turbulence therein. The disclosed structure has the advantage of not only improving the stability, but also lengthening the durability of the water bed mattress. A plurality of longitudinal air tubes run through the transverse partitions and communicate with an air bag for providing a desired softness of the water bed mattresses to suit an individual user's requirements. Moreover, the disclosed water bed mattress is able to support a user's back bone comfortably, and minimize the quantity of water used for the mattress to reduce its weight.

Abstract: A plurality of flexible enclosures are disposed within an article of furniture. The enclosures are positioned to receive the weight of a person resting on the furniture. The enclosures contain a liquid such as water therein. A plurality of electric coils are positioned within the furniture. Each electric coil is within a water-resistant cover, and each cover is positioned adjacent to one of the enclosures. The coils are electrically connected to a controller for changing heat output from the coils, and the coils are electrically connectable to a power source. A water-resistant liner is positioned generally beneath the enclosures. Cushioning material is positioned generally beneath the liner. Foam padding is positioned generally above the enclosures.

Abstract: A water bag for a water bed, including a hollow shell dividing into two inflating chambers at two oposite ends and a plurality of transverse water chambers between the inflating chambers, and a plurality of air bags longitudinally mounted in the transverse water chambers in parallel and respectively connected between the inflating chambers.

Abstract: An air bed includes first and second air-tight enclosures disposed side by side in a first plane. Each of the first and second air-tight enclosures is independently inflatable and has substantially the same length and width, the first and second air-tight enclosures together having a first cross-sectional area in the first plane. An inflatable foundation is disposed below the first and second air-tight enclosures in a second plane substantially parallel to the first plane. The inflatable foundation has a cross-sectional area in the second plane at least as great as the first cross-sectional area. The inflatable foundation is independently inflatable with respect to the first and second air-tight enclosures. The first and second air-tight enclosures and the inflatable foundation are secured together by a circumferential belt, with the first and second air-tight enclosures fixed in place with respect to the inflatable foundation.

Abstract: A multi-layered pad primarily intended to prevent and treat decubitus ulcers. The pad includes at least first and second layers with the first layer being a bladder made up of separate, discrete pouches containing a viscous fluid. The second layer underlies the fluid bladder layer and is a pillared one of upstanding columns cut in a piece of foam. Each individual pouch is mechanically attached atop its underlying foam column. The attaching arrangement includes a connecting sheet of plastic film wherein the sheet is secured to the pouch and has a central opening in it that goes over and receives the top or head section of the column. The connecting sheet at its opening is received in a slit in the column's wall portion to further help maintain the pouch in place atop its column.

Abstract: A water bed in accordance with the present invention comprises a water bed base and a plurality of water bed mattresses. The water bed base defines a number of container chambers into which an equivalent number of water bed mattresses are respectively removably inserted. Each container chamber is sealed and thus advantageously prevents any of the water bed mattresses which may be leaking water from leaking water outside of the water bed base. Further, the leaking water bed mattress, because it is removably inserted into the water bed base, may be individually replaced. Also, the water bed mattress has a plurality of air and water chambers, some having fluid baffles to restrict the free flow of fluids. Further, the water bed base has several air chambers. These chambers maintain the shape of the water bed while providing a regulator and an absorbing means of the pressure inside the water bed. Thus, user comfort is maximized.

Abstract: A cushion unit is provided which is elastically compression-deformable on load. A case is stacked on the upper surface of the cushion unit. The case has an upper surface and lower surface with a receiving section open relative to the upper surface. A water bag is formed of a flexible water-proof sheet and containing a liquid. The stacked cushion unit and case are covered with an outer layer unit.

Abstract: A tube for a waterbed includes a generally cylindrical tube body having a top, a bottom, and a pair of side walls extending from the top to the bottom. The tube body defines a longitudinal axis of the tube. First and second tube ends in combination with the tube body form a watertight enclosure. A fill valve is provided through which the watertight enclosure may be at least partially filled with water. Metering walls are disposed in the watertight enclosure generally transverse to the longitudinal axis of the tube, each pair of metering walls defining a tube section therebetween. The metering walls extend across the tube body from one side to the other and are sealed to each side wall. The metering walls have a top portion that is spaced from the top of the tube body to permit the metered flow of water from one tube section to another. They may also have a bottom portion that is spaced from the bottom of the tube body.

Abstract: The subject matter of the invention is a medical mattress comprising a flexible tubular envelope (1) open at two ends, divided into a central section (3a, 3b) open at both ends and flanked, on either side, by an area forming a border (4a, 4b; 5a, 5b) open at both ends, with two sets of foam elements (8) being insertable in the border sections (4a, 4b; 5a, 5b) and two small water mattresses (7a, 7b) being insertable in the central section (3a, 3b). The elements (7a, 7b, 8) are arranged substantially symmetrical to the transversal center line (T) of the envelope, while the edges (15) facing the water mattresses (7a, 7b) have a concavity forming a central basin (16). An opening (17) formed in the upper wall (1a) of the envelope (1), in the central portion of said basin (16), is connected to one at least flexible tube for discharging body waste and soiled fluids. A device (14) is provided for supplying water to one and/or the other of the two water mattresses (7a, 7b) at a regulated temperature and rate/pressure.
