Abstract

An air mattress includes a supply unit, a first path, a second path, a first flow path part, a second flow path part, a bag part, a plurality of cells, and a pressure controller, the pressure controller performs control to set the pressure inside any one or more of the plurality of cells at the first pressure, when the user lies on the air mattress, the air circulates through at least a part of the bag part located above the cells, whose pressure is set at the second pressure or lower, out of the plurality of cells.

Claims12

Dependent claims

An air mattress comprising:

a supply unit which is configured to supply an air;
a first path and a second path which are supplied with the air from the supply unit;
a first flow path part and a second flow path part which are provided at both ends in a lateral direction and extend in a longitudinal direction, the first flow path part being supplied with the air from the supply unit via the first path, the second flow path part being supplied with the air via the first flow path part;
a bag part whose surface, pressed by a user at least when the user lies on the air mattress, is at least partially formed of a moisture-permeable sheet, which is supplied with the air from the first flow path part and causes the air to circulate at least in the lateral direction, and which is provided between the first flow path part and the second flow path part;
a plurality of cells which are arranged below the bag part at a position between one end and the other end thereof in the longitudinal direction, which extend in the lateral direction, and which are supplied with the air from the supply unit via the second path;
and
a pressure controller which is configured to control pressure inside the plurality of cells, wherein
the pressure inside the plurality of cells includes a first pressure and a second pressure or lower, the second pressure being lower than the first pressure,
among the plurality of cells, the pressure controller performs control to set the pressure inside any one or more of the plurality of cells at the first pressure, performs control to set the pressure inside the cells other than the cells, whose pressure is set at the first pressure, at the second pressure or lower and, among the plurality of cells, sequentially switches the cells between the cells set at the first pressure and the cells set at the second pressure or lower, and
when the user lies on the air mattress, the air circulates through at least a part of the bag part located above the cells, whose pressure is set at the second pressure or lower, out of the plurality of cells.
