Description

Cushion adjustment system {A MATTRESS ADJUSTING SYSTEM}

TECHNICAL FIELD The present invention relates to a cushion adjusting system, and more particularly, to a cushion suitable for use in a chair, massage facility, bedding product, etc., wherein at least two sets of overlapping airbag sets are installed in the cushion, and the cushion supplements the airbag set. And the effect of supporting the cushion according to the changes generated during the air discharge, the massage effect can be obtained, the cushion surface is protruded as a whole can be made to move in a sliding manner.

In the prior art, the cushion arc type is controlled by adjusting the degree of deflection of the cushion by using at least one set of mechanical push rods or protruding wheel mechanisms in the cushion to improve the comfort when leaning on the cushion. The degree of warpage was modified to meet the needs of the user. For example, in the case of the cushion applied to the back of the car seat, by using the seat cushion, such as the car seat to adjust the degree of bending to the shape desired by the user to create the most comfortable state when leaning back.

Among the above-mentioned cushions, the technique of using a mechanical pusher or a protruding wheel device requires a very large installation space, and also has a problem that pressure is not applied uniformly to the cushion surface, which makes the user very uncomfortable. In the event of an accident, even when the car hits the vehicle, pressure is applied to the occupant, causing safety problems.Therefore, a plurality of airbag sets are installed in the cushion to adjust the degree of deflection of the cushion surface by reducing and expanding the airbag set. Has been developed and used. Since these technologies have a moderate buffering effect, they can be said to be the most used techniques now and in the future. However, the reduction and expansion techniques of the airbag set described above form a soft sealed space using the airbag set, and then supplement or discharge air to the space to adjust the strength of the cushion. However, when the pressure in the flexible sealed space is excessively large, the airbag is gradually inflated and deformed into a spherical shape, resulting in a problem that the local part of the cushion is exceptionally inflated and pops out. In particular, when the airbags are inflated while being installed adjacent to each other or very close to each other, a very distinct depression appears between the two airbags.

As a result, when a plurality of airbag sets are installed in one cushion, each airbag set installed in the cushion normally supports and massages when a body part to be leaned or a body part to be massaged corresponds to the recessed part. It could not be exerted, and even if the user is separated seriously enough to feel such a depression. Based on the disadvantages of the conventional structure described above, the inventors have provided a new cushion adjustment system that can further improve the support and massage effect of the cushion.

SUMMARY OF THE INVENTION The main object of the present invention is to provide a cushion adjusting device for solving the above problems, wherein at least two sets of overlapping airbag sets are installed on the cushion, and at least one air supplement pump is used to supplement the air. It is equipped with a main air pipe, each air bag set is connected to the main air pipe through the sub air pipes, on each of the sub air pipes to install a control valve for opening and closing the corresponding sub air pipes, the air The supplementary pump and control valve are controlled by at least one controller.

Through this structure, each air bag set supports the cushion after the air replenishment, and at the same time, the reduction effect during the air discharge and the expansion action during the air replenishment are alternately generated to obtain a massage effect. Because of the superimposed configuration, when one set is in a reduced state and the other is in an inflated state, it is possible to make the cushion surface protrude overall and move in a sliding manner.

In addition, a safety back pressure valve is further installed on the main air pipe so that the safety back pressure valve safely acts as a back pressure when the pressure in the main air pipe is excessively large. In addition, a pressure sensing unit is further installed on the main air pipe to sense the pressure in the main air pipe. In addition, a pressure sensing unit is also installed on each sub air pipe to sense the pressure in the sub air pipe. The pressure sensing unit allows the controller to more accurately perform the air replenishment and azeotrope operations for each air bag set and further allows the controller to record the air replenishment status of each air bag set.

Compared with the prior art, the present invention is to adjust the degree of arc type bending of the cushion by using the air bag set, and also to change the degree of arc type bending of the cushion more precisely through the pressure control, thereby the air bag and the air bag No depressions are created in between, improving comfort when the user leans on the cushion. In addition, according to the pressure dispersion effect of the cushion itself, when the airbags are replenished and discharged, the arc-shaped deflection of the airbag surface is uniformly deformed to conform to ergonomics. In addition, the cushion's support and massage effect can be more precise and comfortable. In addition, one of the two sets of overlapping airbags is reduced by air discharge, and when the other set is inflated with an airfill, the cushion surface can be protruded and moved in a sliding manner. This improves the feel and comfort of use in a different way than conventional two airbag sets installed at regular intervals inflating each other and indirectly improves the overall texture of the cushion.
