Patent number: 8037564Abstract: The air cells are attached detachably to the base members. By this, it is possible to set up the size or the arrangement of the air cells. For example, in a hospital, it is possible to change easily and inexpensively the air cells on a bed according to the patient's height, the body shape, the state, or the condition of affected part. Thus, it is exceedingly advantageous for dispersing the pressure added to the body.Type: GrantFiled: December 5, 2007Date of Patent: October 18, 2011Assignees: The Yokohama Rubber Co., Ltd., The University of TokyoInventors: Hajime Satoh, Hiromi Sanada

Publication number: 20090106905Abstract: There is realized a configuration in which, even when pressure is concentrated, the pressure can be adjusted based on accurate and precise detection of pressure distribution, thereby providing sleeping comfort. An air mattress device has a sensor that detects the distribution of pressure applied to an elastic sheet, by means of light emitting parts and light receiving parts of optical fibers uniformly distributed in the elastic sheet. Based on pressure distribution detected by the sensor, the air mattress device adjusts the amount of gas filled in an air mattress. The sensor can be disposed above the air mattress of the air mattress device.Type: ApplicationFiled: October 12, 2006Publication date: April 30, 2009Applicants: Nitta Corporation, The University of TokyoInventors: Shinya Ochi, Hiromi Sanada
