Mat body adjusting system

Abstract

The invention relates to a mat regulating system which is mainly provided with at least two groups of air bag groups that are mutually jointed with each other in a mat body; and at least one charge pumping feeds air to a main air passage; each air bag group is connected with the main air passage through a branch air passage, and each branch air passage is provided with a control valve used for opening and closing the branch air passage; the running of the charge pumping and the control valve is controlled by at least one controller; besides the function of leading each air bag group to support the mat body after the air bag group is charged, the mat body can also have the effect of massage by utilizing the alternation of exhaust shrinkage and charge inflation; in addition, when the two groups of air bag groups that are mutually jointed are in the state of exhaust shrinkage and charge inflation, the surface of the mat body takes on the state of slippage of the position of protuberance.

Description

technical field [0001] The invention relates to a cushion adjustment system, which is most suitable for cushions such as seats, massage equipment, bedding products, etc., and at least two sets of overlapping airbags are arranged in the cushion to penetrate through the airbags. Changes occur when inflated and exhausted, so that the cushion body presents the state of support, massage and sliding of the raised parts. Background technique [0002] In order to improve the comfort of the cushion body when leaning on it, in the prior art, at least one set of mechanical push rods or cam devices are embedded in the cushion body to adjust the curvature of the cushion body, so that the curvature of the cushion body can be changed. For example, if it is used in the back cushion of a car seat, the curvature of the back cushion of the car seat can be changed to adjust the lumbar effect required by the user. [0003] The aforementioned technology of embedding mechanical push rods or cam d...

Problems solved by technology

[0004] However, the application of the air bag group deflation technology is to use its air bag group to form a soft airtight space, and to control the inflation and deflation of the air bag group, so as to change its deflation effect; but , when the pressure in the soft airtight space is higher, the airbags will become more and more inflated, and will become closer to a spherical shape, resulting in a particularly bulging situation in the cushion body; especially when the airbags are adjacently arranged Or when it is set close to the convex, it will produce an obvious relative concave area between the two air pockets

[0005] Therefore, when a plurality of air bag groups are arranged in a pad body, if the user needs to obtain support or the part to be massaged is just located in the recessed area, the air bags set in the pad body will often be affected. group, can not exert its support or massage effect, and even make the user feel the segmented and discontinuous support effect; Excellent support, massage and adjustment effect
