Document Type and Number:
Japanese Patent JP6706112
Kind Code:
B2
Abstract:
The invention provides a fluid cell type mattress and a control method thereof. The fluid cell type mattress can realize a supporting surface which can accurately and better handle the distribution of a user's body pressure in a novel and simple structure. The fluid cell type mattress (10) is provided with a unit set (48) which is constituted by a plurality of units (30). The fluid chambers of the plurality of units (30) that constitute the unit set (48) are mutually communicated through an intra-set through channel (46), and the intra-set through channel (46) is provided thereon with first valves (50) which manage the on and off of the fluid chambers (32) of the plurality of units (30) which constitute the unit set (48). On the other hand, a plurality of unit sets (48) are provided, and an inter-set through channel (84) which connect the plurality of unit sets (48) is connected to respective first valve (50) of the plurality of unit sets, such that the through resistance of the intra-set through channel (46) is smaller than the through resistance of a drain side flow path (94) which is constituted by including the inter-set through channel.
