[1] Field

[2] The present invention relates to a cushion body adjusting system, which is most suitable for use in a cushion body such as a seat, a massage device, a bedding product, etc., and is provided with at least two sets of airbag sets overlapping each other in the cushion body, and the cushion body can pass The air bag group changes when inflating and exhausting, so that the pad body is in a state of supporting, massaging, and sliding of the convex portion.

[3]

[4] In order to improve the comfort of the cushion body during the cushioning, the prior art embeds at least one set of mechanical push rods or cam devices in the cushion body to adjust the curvature of the cushion body to change the curvature of the cushion body. It is suitable for the user's demand state, for example: When used in the back cushion body of the car seat, the curvature of the back seat of the car seat can be changed to adjust the lumbar effect of the user's demand.

[5] The above-mentioned technique of embedding a mechanical push rod or cam device in the pad body occupies considerable space for installation, and also causes uneven pressure on the surface of the pad body, making the pad holder relatively uncomfortable, even in a car. When colliding, it will cause improper concentration pressure on the occupants and is not safe to use. Therefore, the technique of arranging a plurality of air bag groups in the cushion body and adjusting the curvature of the surface of the cushion body by the increase of the airbag group has become a mainstream of the present and the future due to an appropriate cushioning effect.

[6] However, the application of the air bag group's anti-shock technology is to use its air bag group to form a soft confined space, and to control the air bag group to charge and deflate, and to carry out its anti-lift effect. Change; however, when the pressure of the soft confined space is greater, the air bag will become more and more bulging, and will become closer to a spherical shape, causing a particularly convex part of the pad; especially when the air bags are When the adjacent setting or the close arrangement is convex, a distinct relative recessed area is created between the two air pockets.

[7] Therefore, when a plurality of air bag sets are provided in one pad body, if the user needs to obtain a support portion or a part to be massaged, just in the recessed area, the pad body is often disposed. Each air bag group cannot exert its supporting or massaging effect, and even allows the user to feel the segmented and discontinuous supporting effect; in view of this, the inventor provides a pad body adjusting system to enable the pad body to be presented. Better support, massage and adjustment results.

[8] ^"Cai Rong [9] The technical problem to be solved by the present invention is to provide a cushion body adjusting system, which is provided with at least two sets of air bag sets overlapping each other in the cushion body, and supplies air to a main air passage by using at least one air pump. Each air bag group is connected to the main air passage through an air passage, and each air passage is provided with a control valve for opening and closing the air passage, and the operation of the air pump and the control valve is controlled by at least one controller .

[10] According to this, in addition to the effect that each air bag group can generate support for the pad body after inflation, the alternating body of the air venting and the inflation of the air can be used to make the pad body have a massage effect; The two groups of airbags overlapping each other may exhibit at least one state of exhaust gas reduction and inflation, and no recessed area is formed between the stacked airbag groups, so that the surface of the cushion body can be raised. The state of the slip.

[11] In addition, a safety relief valve can be further disposed on the main airway. When the internal airway pressure is too large, the safety relief valve can perform a safe pressure relief operation. In addition, a pressure detection can be set on the main airway. The measuring unit detects the internal pressure of the main airway; in addition, a pressure detecting unit can be arranged on each airway to detect the internal pressure of the airway, which is beneficial to the controller for each air bag. The precise control of the group's inflation and exhaust is even beneficial for the controller to record the degree of inflation of each air bag set.

[12] Compared with the prior art, the present invention adjusts the curvature of the pad body through the air bag group, and can accurately change the curvature of the pad body through pressure control, and between the air bag and the air bag. There will be no obvious recessed area, which will make the user's comfort when padding more. Secondly, with the pressure dispersion effect of the cushion body itself, the airbag can be rendered on the surface of the cushion body when it is filled and deflated. The curvature of the arc is more uniform and gentle and ergonomic; in addition, the support and massage effect of the cushion body can be more precise and comfortable, and when the two groups of airbags overlapping each other are reduced in exhaust gas and the other is inflated When it is swollen, the surface of the pad body can be seen to be in a state of slippage of the convex part, instead of increasing the distance and the distance, the touch and the comfort are improved, and the overall texture of the pad body is indirectly improved.
