Description

Pad adjustment system

technical field

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

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.

The aforementioned technology of embedding mechanical push rods or cam devices in the cushion body takes up a lot of installation space, and also causes the problem of uneven pressure on the surface of the cushion body, which makes the cushioner quite uncomfortable, and even collides with the car When it is used, it will generate undue concentrated pressure on the occupant, which is quite unsafe to use. Therefore, the technique of arranging a plurality of airbag groups in the cushion body and adjusting the curvature of the surface of the cushion body by the expansion and contraction of the airbag groups is the mainstream at present and in the future because of its proper cushioning effect.

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 protruding when arranged close to each other, an obvious relative concave area will be produced between the two air pockets.

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.

Contents of the invention

The main purpose of the present invention is to provide a cushion adjustment system, which is to set at least two groups of overlapping airbags in the cushion, and supply air to a main airway with at least one inflatable pump, each airbag The group is connected with the main airway through an airway, and each airway is provided with a control valve for opening and closing the bronchial airway, and the operation of the aforementioned inflatable pump and control valve is controlled by at least one controller.

According to this, in addition to making each airbag group produce the effect of supporting the cushion body after inflation, the cushion body can also have a massage effect by using the alternation of exhaust gas shrinkage and inflation expansion; and the two groups can also be mutually The stacked air bag groups can at least show a state of shrinking when exhausted and expanding when inflated. At this time, there will be no recessed areas between the stacked air bag groups, so that the surface of the cushion body can show convex parts to slide appearance.

In addition, a safety pressure relief valve can be further installed on the main airway. When the internal pressure of the main airway is too high, the safety pressure relief valve can perform the action of safe pressure relief; in addition, a pressure detection unit can also be set on the main airway. Detect the internal pressure of the main airway; in addition, a pressure detection unit can also be installed on each airway to detect the internal pressure of the bronchial airway, so as to facilitate the controller to inflate and exhaust each air bag group. It is even beneficial for the controller to record the inflation degree of each airbag group.

Compared with the prior art, the present invention adjusts the curvature of the cushion body through the airbag group, and can precisely change the curvature of the cushion body through pressure control, and there is no gap between the airbags and the airbags. The obvious concave area improves the comfort of the user when leaning on it; secondly, with the pressure dispersion effect of the cushion itself, it can make the curvature of the surface of the cushion when the air bags are inflated and deflated. It is relatively uniform and gentle and conforms to ergonomics; moreover, it can make the support and massage effect of the cushion body more precise and comfortable. , allowing the surface of the pad to show the appearance of sliding of the raised parts, instead of rising and falling at a certain distance, which not only improves the touch and comfort during use, but also indirectly improves the overall texture of the pad.
