Abstract: A support cushion for providing individualized heating and cooling to a user resting on the support cushion is provided. The support cushion includes a body supporting portion, a plurality of thermoelectric elements positioned and configured to selectively provide heating or cooling of the body supporting portion, and a heat dissipating portion that is comprised of a thermally-absorbent material and is operably connected to the thermoelectric elements. Methods of controlling a surface temperature of a support cushion are also provided.
Abstract: A body support assembly comprising a first layer (e.g., a visco-elastic foam) having a lower surface, and a second layer supporting the first layer and having an upper surface. One of the upper and lower surfaces is defined by a non-planar surface to define a plurality of passages. A fan is positioned to move air through the passages. Preferably, the non-planar surface comprises a plurality of protrusions (e.g., a convoluted surface). The body support can further comprise a sensor that detects a parameter and produces a signal, and a controller coupled to the sensor and programmed to control the fan. Multiple fans and sensors can be provided, and the controller can control the fans to provide different air flows through different locations of the body support assembly. A user interface can be coupled to the controller to allow selection of a desired parameter of the body support assembly.
Abstract: A body support assembly includes a layer including a visco-elastic foam, a heating element in thermal communication with the foam, a temperature sensor, such as a Peltier device, in thermal communication with the foam, and a controller coupled to the sensor and programmed to control the heating element based on input from the sensor, wherein the Peltier device is operable to heat and cool the foam.
Abstract: A body support assembly includes a body support having a head portion, a middle portion, and a foot portion. The body support assembly also includes a foundation underlying and supporting the body support proximate an edge of the body support at one of the head and foot portions, and a bracket coupled to the foundation and slideable between first and second positions at different distances with respect to the edge of the body support.
Abstract: A support cushion including a top surface, a bottom surface opposite top surface, a layer of flexible foam having plurality of cells defining a reticulated cellular structure, the reticulated cellular structure cells comprising a skeletal plurality of supports through which substantially open cell walls establish fluid communication between interior of the cell and interiors of adjacent cells, the layer of flexible foam having density no less than about 30 kg/m3 and no greater than about 175 kg/m3, and hardness of no less than about 20 N and no greater than about 150 N at 40% indentation force deflection measured at about 22 degrees Celsius, the layer of flexible foam comprising visco-elastic foam having at least one material property responsive to temperature change in range of 10-30° C., and layer of polyurethane foam located beneath layer of flexible foam, the layer of polyurethane foam having hardness of at least about 50 N.
