Abstract: A mattress including: a support surface to support a user; a mattress main body that constitutes the support surface; at least one pressure sensor having a flexible sheet shape to detect a pressure acting on the support surface; a support surface cover positioned with respect to the mattress main body and arranged so as to cover the support surface; and at least one positioning member provided to the support surface cover to permit a movement of the pressure sensor with respect to the support surface cover in a planar direction while limiting an amount of the movement of the pressure sensor with respect to the support surface cover in the planar direction such that the pressure sensor is positioned on the support surface by the positioning member.

Abstract: A mattress including: substrates configured to support a human body; and a plurality of cells arranged on an upper face of each substrate, the cells including respective fluid chambers. The substrates are divided from each other at a location corresponding to a folding part provided to a portion of a bed in a length direction thereof such that cell units are constituted by the respective substrates and the cells arranged thereon. The cell units are disposed such that the cell units are adjacent to each other with the folding part interposed therebetween. A connecting body is disposed between the cell units such that the connecting body straddles the cell units and is supported by the cells of the cell units.

Abstract: A mattress including a plurality of cells aligned and disposed on a body pressure working surface of a substrate that supports a human body; and a pressure control member that changes a height of each cell by adjusting a pressure in a fluid chamber formed within the cell. The cells are configured such that as the each cell is inflated by fluid supplied to the fluid chamber within the cell, the height of the each cell increases and a width dimension of the each cell in a direction of alignment decreases, and that peripheral portions of adjacent cells in the direction of alignment are overlapped with each other prior to cell inflation.

Abstract: The objective of the present invention is to provide: a cushion cell with a new structure which is designed to disperse stresses when the cushion cell is in an inflated state such that excellent durability is achieved and in which a large support area for the human body can be obtained with excellent space efficiency relative to a square shaped space for disposal in an inflated state; and a cushion body with a new structure using the same. The cushion cell is formed with a fluid chamber inside and the height of the cushion cell can be changed by adjusting the pressure in the fluid chamber. The planar shape of the cushion cell in a deflated state is a square shape, and each side part has a curved shape protruding outwards.

Abstract: The objective of the present invention is to provide a mattress including a plurality of cells provided on a body pressure working surface of a substrate that supports a human body, and a pressure control means that changes a setting of a height of each cell by adjusting a pressure in a fluid chamber formed within the cell. An elastic cushion layer is provided on a body pressure working surface of the cells, and a constricted portion is formed in a middle in the height of the each cell so that the body pressure working surface of the cell is allowed to tilt following deformation of the cushion layer as a result of the cells' precession-deformation at the constricted portion.

Abstract: The object of the present invention is to provide a mattress of a novel structure that can quickly perform dispersion of a body pressure acting part of a user, and can reduce discomfort felt by the user when doing a cell internal pressure switching operation, as well as a control method thereof. The present invention is provided with: a grouping step for, on the basis of a body pressure applied to each of a plurality of cells, dividing the plurality of cells into groups; a target internal pressure setting step for setting a target internal pressure of the cells for each group divided at the grouping step; and an internal pressure adjusting step for interconnecting the cells in each group and adjusting the internal pressure of the cells to the internal pressure set in the target internal pressure setting step.
