AIR MATTRESS
Document Type and Number:
WIPO Patent Application WO/2020/148930
Kind Code:
A1
Abstract:
An air mattress according to one embodiment comprises: an air cell part comprising air cells; and a control unit that controls the internal pressure of the air cells. When the internal pressure of the air cells satisfies a second condition after having satisfied a first condition, the control unit executes a first operation. The first condition includes: the internal pressure reaching a second value, which is lower than a first value, from the first value; the difference between the first value and the second value being at least a first threshold value; and the rate of change over time of the internal pressure from the first value to the second value being at least a second threshold value. The second condition includes: the internal pressure reaching a third value, which is lower than the second value, after having dropped from the first value to the second value; and the difference between the second value and the third value being at least a third threshold value. In the first operation, the control unit shifts the internal pressure towards the second value.
