Patent number: 10889680Abstract: A method of making flexible polyurethane foams mixes a polyol (a hydroxyl group containing compound) with a cesium and/or rubidium fluoride catalyst, and reacts such mixture with at least one isocyanate. The cesium and/or rubidium fluoride may be used as the sole catalyst, replacing the blowing and gelling catalysts, such as amines, and metallic catalysts, such as a tin catalyst. Or, the cesium and/or rubidium fluoride may be used as a catalyst promoter in combination with traditional amine blowing and gelling catalysts and tin catalysts. The resulting flexible polyurethane foams exhibit increased thermal conductivity and lower levels of volatile organic compound emissions.Type: GrantFiled: January 25, 2019Date of Patent: January 12, 2021Assignee: FXI, Inc.Inventors: Alex Sergey Ionkin, Arianna Lubomyra Watters

Patent number: 10477975Abstract: Body support systems such as mattresses include breathing layers that define internal air flow guides and form part of the structure for pressure redistribution. At least one air flow unit is coupled for fluid communication with the breathing layers so that heat and moisture may be drawn away from an uppermost comfort layer or body-supporting layer, through the breathing layers, and exhausted out of the body support system. Alternatively, air may be directed through permeable portions of the layers of the body support system to the uppermost layer, particularly at the torso supporting region.Type: GrantFiled: July 24, 2015Date of Patent: November 19, 2019Assignee: FXI, Inc.Inventors: Daniel V.

Patent number: 10154933Abstract: A compressible or retractable support (10, 80, 90, 100) is installed inside an air blower cavity (36) of a body support system (30), such as a medical mattress with forced air flow. The support is compressed or retracted within the cavity when the air blower (40) is inserted in the dynamic configuration of the body support system. The support rebounds to an uncompressed state to fill a greater portion of the air blower cavity when the air blower is removed to convert the body support system to a static configuration.Type: GrantFiled: February 5, 2016Date of Patent: December 18, 2018Assignee: FXI, Inc.Inventors: Marc J.

Patent number: 9950654Abstract: A method of making a headrest includes folding a first sheet of foam into a foam sleeve. The foam sleeve is slid over an internal core part of the headrest. The foam sleeve and the core part in turn are covered with an outermost cover. The cover is formed from (i) a first layer of material corresponding to a front face of the cover, (ii) a second sheet of foam having a periphery substantially the same shape as the first layer of material, affixed to a backside of the first layer, (iii) a second layer of the material corresponding to a rear face of the cover, and (iv) a third sheet of foam having a periphery substantially the same shape as the second layer of material, affixed to a backside of the second layer. The front and rear faces are joined together to form the cover.Type: GrantFiled: December 17, 2015Date of Patent: April 24, 2018Assignee: FXI, Inc.Inventors: Jose D. M. Contreras, Jovan Rafael Phillips

Patent number: 9392875Abstract: Body support systems include central cores having one or more internal air flow guides that form part of each system for pressure redistribution, and withdrawal of heat and moisture away from an uppermost comfort layer or body-supporting layer(s). During operation of the system, heat and/or moisture is directed from the uppermost comfort layer or body-supporting layer(s) into the central core portion of the body support system and out of the body support system. The internal air flow guide(s) are formed of cellular polymer material and are coupled to the uppermost comfort layer to form an air flow path.Type: GrantFiled: January 18, 2013Date of Patent: July 19, 2016Assignee: FXI, Inc.Inventor: Christopher S.
