Having Uniform Firmness, Changeable By User Patents (Class 5/697)
  • Patent number: 9119479
    Abstract: The present invention provides a body support assembly comprising a layer having a passage, a pump positioned to create a flow of fluid through the passage, a sensor that detects a parameter and produces a signal, and a controller coupled to the sensor and programmed to control the flow of fluid based on the signal. Preferably, the layer comprises visco-elastic foam. In one embodiment, the parameter corresponds with a firmness of the layer (e.g., a temperature of the layer). A heat exchanger can be used to alter (e.g., heat or cool) a temperature of the fluid. The present invention further provides a method of controlling a firmness of a body support comprising sensing a sensed value of a parameter (e.g., temperature) of the body support, establishing a desired value of the parameter, comparing the sensed parameter to the desired value, and adjusting the parameter.

  • Patent number: 7127763
    Abstract: Safety features for a crib mattress are described. One safety feature is designed to maintain airflow to a fan inlet despite the fan inlet being blocked by a mattress sheet. Another safety feature removes obstructions to airflow within the mattress so that air is dispersed more uniformly across the sleep surface which is formed by a taut sheet of fabric. Yet another safety feature is designed to help retain a fitted sheet on a mattress and make it difficult for the sheet to be inadvertently pulled off the mattress.

  • Patent number: 5857232
    Abstract: The present invention provides a safety device and a method to counter a potential cause of Sudden Infant Death Syndrome. A frame, fit to the dimensions of a crib or bassinet is equipped with an air permeable material that allows for the free flow of fresh air to an infant's mouth and offsets any exhaled carbon dioxide that lingers by the infant's air passages. The material is of a particular elasticity that an infant's weight does not cause the material to collapse on itself, thereby keeping the supply of fresh air retained in the material in place.
