  • Patent number: 11155190
    Abstract: A vehicle seat heater is provided in a vehicle seat. This vehicle seat heater includes a first heat generator, second heat generator, and controller. The first heat generator is disposed in a first area of the vehicle seat supporting an occupant. The second heat generator is disposed in a second area not being in contact with the occupant or being less pressed by the occupant than the first area is. The controller controls current application to the first heat generator in a manner such that a heating temperature zone of the first heat generator is a direct heat transfer temperature zone close to a body temperature of the occupant, and also controls current application to the second heat generator in a manner such that a heating temperature zone of the second heat generator is a radiation heat transfer temperature zone.

    Abstract: An apparatus for suspending bedclothing which comprises a rectangular cross frame, four supporting posts extending downwardly from corners of the rectangular cross frame, a pair of wires from the cross frame, grasping members connected to one ends of the chains, a pair of rods disposed in the underside of the bedclothes whereby the bedclothing hangs by the chains for relieving the occupant from the weight of the bedclothing and treating various regions of the body of the occupant on the bed. In addition, the occupant of the bed can used light emitting members which may operate as a sauna, and TV and video cassette sets supported by the supporting post thereof.

  • Patent number: 4867230
    Abstract: A convection blanket for warming persons lying thereon. The preferred embodiment has four layers, two outer insulating layers, and two inner layers of metallic foil. The inner metallic layers minimize heat loss across the length of the blanket. A unique pattern of pinholes in the top layers allows a larger volume of warm air to exit the blanket at the end opposite the air supply hose. All layers are stitched intermittently to avoid distension of the blanket, without defining clear channels, assuring uniform distribution of air within the blanket.

  • Patent number: 4559656
    Abstract: A bed uniformly distributes the weight of a bed-ridden patient to minimize the occurrence of bedsores. The bed comprises a frame and a plurality of support assemblies mounted on the frame. Each support assembly comprises a plurality of elongate support slats extending transversely of the fore-aft direction, and a pair of transversely spaced lever modules carrying opposite ends of the slats. Each lever module comprises a plurality of levers which are so mounted as to be swung in response to the downward action of heavier portions of the patient, whereupon opposite ends of the levers swing upwardly to transfer some of that weight to the lighter portions of the patient's body. The levers disposed on one side of the bed are rotatable relative to the corresponding levers on the opposite side of the bed, whereby the support slats may assume positions inclined relative to horizontal and thereby maintain a greater degree of contact with the patient.

  • Patent number: 4525884
    Abstract: This invention relates to sun beds. In the described embodiment the bed has an elongate base (1) which is generally flat but has a rim (2) of inverted U-form. The base (1) is covered by a dome (4). The base (1) has a frame with a plurality of vents (11), while the dome has a vent formed in a blister (9). The vents are positioned such that solar action generates convection currents which will draw air in through the base vents as hot air escapes through the dome vent.

  • Patent number: 4491721
    Abstract: An electric bed heating device for attachment to the understructure of a bed for supplying heat to a sleeper includes an electric heating element mounted below a metallic plate thermally insulated on its upper side and having a lower face shaped to radially downwardly direct heat. In one embodiment the heating element is directly supported by vertical fins extending downwardly and radially outwardly from the lower face of the plate with the fins and heating element being exposed. In another arrangement a serially slit lower metallic plate is spaced below the first mentioned plate to allow flow of air therebetween. The lower plate supports an electric heating element in the path of the air flow. The slits in the lower plate form offset air inlet and outlet openings. The plates are aligned and attached to the bed structure by a central fastener binding the plates together. The upper face of the lower plate is roughened and blackened to enhance heat absorption.

  • Patent number: 4468825
    Abstract: A system for removing oxygen from and around hospital beds for reducing the fire danger. A manifold having a plurality of sections is connected to and is supported from the frame. The sections are connected together by flexible joints and include a connection for attachment to an exhaust. A first plurality of suction tubes is connected to the manifold with their ends positioned adjacent the mattress for removing oxygen from and around the mattress. A second plurality of suction tubes is connected to the manifold and extend downwardly for removing oxygen from beneath the bed. Suction cups may be connected to the ends of the first suction tubes positioned adjacent the mattress. The suction cups are positioned adjacent the sides and the bottom of the mattress and are supported from the frame and springs.

  • Patent number: 4455472
    Abstract: A bed heater with two spaced, perforated, non-metallic plates between which there is arranged spaced loops of an insulated cover-type resistance heating fuse wire. At least some side area between the plates is open allowing lateral movement of air to prevent overheating. Power is supplied through a parallel SCR and diode circuit controlled by an R-C circuit including a temperature responsive resistor and a light responsive resistor.
