Detailed Description

Examples

Referring to fig. 1 to 3, the present embodiment provides a support pad with adjustable softness and hardness, which includes a sealed bag 1 suitable for being filled with fluid, wherein an inner cavity is formed in the sealed bag 1; a plurality of partition plates 6 are arranged in the sealed bag, the plurality of partition plates 6 are suitable for dividing the inner cavity into a plurality of sub-units, and a support body 7 made of porous materials is arranged in each sub-unit; the support pad is configured to be adjustable between at least a first hardness formed by the support body only when not filled with the fluid, a second hardness formed by the fluid and the support body together after being filled with the first set amount of the fluid, and a third hardness formed by the fluid only after being filled with the second set amount of the fluid;

wherein the first hardness is less than a second hardness, which is less than a third hardness;

wherein the second set amount is greater than the first set amount.

In this embodiment, the sealed bag 1 can be an air bag of a massage chair, which can be divided into an upper layer 11 and a lower layer 12, and the upper layer 11 and the lower layer 12 are connected in a sealing manner. Be provided with air cock 2 on the sealing bag 1, air cock 2 is used for being connected with trachea 5, and pump body 4 or pneumatic valve 3 are connected to through trachea 5 on the air cock 2 of sealing bag 1. In this embodiment, the gas filled in the sealing bag 1 is taken as an example for explanation. The pump body 4 can use an air pump to inflate the sealed bag 1 so as to perform height adjustment on the sealed bag 1, wherein an air valve 3 is arranged to control air discharge in the sealed bag 1. The gas valve 3 and the pump body 4 are both of the prior art and are not described in detail herein.

The partition boards 6 can be made of TPU (thermoplastic polyurethane) or 240D oxford cloth with TPU attached to the two sides, the partition boards 6 are fixed on the upper layer 11 and the lower layer 12 of the sealing bag 1 in a voltage welding machine mode, the partition boards 6 are distributed in a staggered mode, the height can be set according to actual conditions, and a cavity for accommodating the supporting body 7 is formed between every two adjacent partition boards 6; the cavities may be irregular or square, and the present embodiment is not limited in particular. In the preferred embodiment, the baffles 6 are uniformly distributed to form uniform square or circular cavities, thereby improving the user experience when sitting down. Of course, the material of the partition board 6 is not limited to the TPU material; the fixing mode is not limited to the voltage welding mode, and the specific fixing mode can be selected according to the adopted materials. It should be noted that the shape and thickness of the partition 6 are not particularly limited herein.

The support body 7 can use porous materials such as sponge and foaming materials, is filled in a subunit cavity enclosed by the partition plates 6 and is limited by the subunit, so that when the sealing bag 1 is filled with gas, the support body 7 cannot move randomly in the sealing bag 1, and the human body can be caused to be deviated after sitting on the cushion. Of course, the support body 7 is not limited to the listed ranges, and other materials with the same properties are also within the scope of the present invention.

The utility model discloses in, the fluid can adopt gas or liquid, works as when the fluid is gaseous, then pump body 4 adopts the air pump, works as when the fluid is liquid, then pump body 4 can adopt the liquid pump.

The utility model discloses a theory of operation does:

the amount of fluid in the sealed bag 1 is controlled by the pump body 4. In an initial state: the sealing bag 1 is not filled with fluid, no pressure exists in the sealing bag 1 at the moment, the support body 7 in the bag plays a supporting role, the hardness is moderate, and the supporting pad is in a first hardness state at the moment.

A cushion softening process: the air pump works to fill a first set amount of fluid to gradually increase the pressure in the sealed bag 1, and after a certain pressure is reached, the air pressure in the bag plays a supporting role, and the product is in a softer state (similar to a water bed). I.e. the support pad is in the second hardness state

The cushion hardening process: the air pump works, the fluid with the second set amount is filled, the sealing bag 1 is filled with air, the partition plate 6 in the bag can pull the bulged surface at the moment, the bulged height of the cushion is consistent after the cushion is filled with air, the horizontal supporting effect is achieved, and the product is in a harder state at the moment. I.e. the support pad is now in the third hardness state.

Cushion softness and hardness keeping process: when the hardness is adjusted to a proper position, the air valve 3 is closed, and the pressure in the bag is kept stable;

the specific values of the first set amount of fluid and the second set amount of fluid are set as the case may be, but the second set amount is greater than the first set amount so that the third hardness is greater than the second hardness, which is greater than the first hardness. Through crisscross baffle 6 and the supporter 7 of laminating each other in the cushion, make the cushion inflate the back and swell highly unified, let the cushion keep the optimum user state of people. The states are from soft to hard, and the hardness can be adjusted according to the requirements of each person.

The embodiment of the utility model provides a still provide a car seat, car seat is including the aforesaid the supporting pad, through this supporting pad for car seat can carry out the regulation of soft or hard degree.

The utility model discloses the cushion can extensively be applicable to mattress, sofa pad and car seat etc. can also arrange or range upon range of through with this air cushion to constitute bigger or thicker cushion combination. Various means can be used for sealing the fluid filling in the bag 1, improving the applicability, while various materials or combinations of materials can be used for the baffle 6 and the support 7. Through the utility model discloses, can adjust the height and the hardness of air cushion to make the air cushion highly uniform after aerifing, can also make cervical vertebra, lumbar vertebrae no longer incline, alleviate the health dead weight and to vertebra, muscle, microvasculature and nervous system's pressure, play the nursing effect to the backbone, can alleviate fatigue well, improve the physiological function that promotes the human body, it is useful to the people, and can improve user experience and feel.

It should be understood that: above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
