Abstract
Provided are an air cell device and an air mattress system thereof. The air cell device includes an air cell which has therein an upper connection segment and a lower connection segment. The upper connection segment and the lower connection segment each have a curved portion whereby the air cell is partitioned to become a multilayered air cell so as to mitigate air cell bending or air cell inversion, thereby improving the lying human being's comfort.
Claims11
An air cell device, comprising:
- an air cell, when inflated, including an air cell wall, two long sides defined by the air cell wall, two short sides defined by the air cell wall, and two height sides defined by the air cell wall, the air cell wall having a left air cell wall and a right air cell wall which are defined on two sides of the long sides, wherein the air cell has an upper connection segment and a lower connection segment which are formed by joining of the left air cell wall and the right air cell wall and extended along the long-side direction, wherein the upper connection segment and the lower connection segment each have at least one curved portion;
- and
- an air transfer unit in fluid communication with an inside of the air cell and an outside of the air cell to transfer air.
An air mattress system, comprising a plurality of air cell devices arranged along the lengthwise direction of the air mattress to at least support a lying human being's head region, shoulder regions, back region, buttock regions, thigh regions and leg regions, wherein the air cell devices each comprise:
- an air cell, when inflated, including an air cell wall, two long sides defined by the air cell wall, two short sides defined by the air cell wall, and two height sides defined by the air cell wall, the air cell wall having a left air cell wall and a right air cell wall which are defined on two sides of the long sides, the air cell having an upper connection segment and a lower connection segment which are formed by joining of the left air cell wall and the right air cell wall and extended along the long-side direction, wherein the upper connection segment and the lower connection segment each comprise a curved portion asymmetrically positioned;
- and
- an air transfer unit in fluid communication with an inside of the air cell and an outside of the air cell to transfer air,
- wherein deflation of part of the air cell devices is controlled to be independent of the other air cell devices.
