Seat air cushion

Abstract

The utility model relates to an air cushion applied to chairs, armchairs and stools. The air cushion has the advantages that when a user sits, especially when the user needs to sit for a long time, under the condition that the body posture does not need to be changed, the air cushion can massage the buttocks of the user, muscle tension of the buttock area is relieved, the user does not need to frequently get up to move, and therefore working efficiency is improved, and when the user needs to sit for a long time in long-distance flight or travel, the user can feel comfortable when sitting for a long time. The air cushion can reduce discomfort caused by the fact that a user cannot stand or stretch. The technical effect is achieved in that the air cushion comprises an air chamber (a seat part located above the seat base), a valve and a controller (capable of controlling the inflation degree of the air chamber), an air pump and an air pipeline system, the air chamber can be made into a long and thin shape or other geometrical shapes (round, oval and the like), the air chamber is connected to form an inflation section, and the inflation section is connected to the valve and the controller. And the air chambers of one inflating section and the air chambers of the other inflating section are arranged in a penetrating manner.

Description

Technical Field

[0001] The utility model relates to an air cushion applied to a chair, an armchair and a stool. Background Art

[0002] The known solution US5243721 [2] "Inflatable cushion and air supply device with switch valve" comprises: a plurality of inflatable segments under a flexible outer cover; a pump; a plurality of switch valves, each of which is connected to at least one of the inflatable segments.

[0003] A disadvantage of the known solution is that it is not possible to place the product on a chair in order to massage the buttocks while a person is sitting, nor is it possible to carry the product for use while travelling.

[0004] The technical solution closest to the one for which protection is sought is RU2697175 [1] “Vehicle seat”, which comprises: an air chamber, the seat part located on the cushion material above the seat base; a valve and a controller that can individually control the inflation level of each air chamber (not inflated, partially inflated, fully inflated); and a bypass air intake system, including a pump and multiple air bypass lines.

[0005] The device allows a person to sit down.

[0006] The device has the following disadvantages: it cannot be used in daily life. For example, when sitting in front of a computer, it is impossible to perform local massage on the buttocks area to relieve muscle tension in the buttocks area, resulting in the need to frequently get up and move the body. Utility Model Content

[0007] The technical effect of the utility model is that when the user is sitting, especially when the user can only sit for a long time and cannot stand up and move, such as taking a long ride on an airplane or a train, the air cushion can massage the buttocks without changing the body posture, thereby relieving muscle tension in the buttocks area and eliminating the need to frequently get up and move, thereby improving work efficiency. In addition, when the user needs to sit for a long time during a long-distance flight or trip, the air cushion can reduce the discomfort caused by the user's inability to stand up or stretch, and the air cushion is also portable and can be carried and used during travel.

[0008] The technical effect is achieved in the following way: the air cushion includes an air chamber (located in the seat part above the seat base), a valve and a controller (which can control the inflation degree of the air chamber), an air pump, and an air pipe system, characterized in that the air chamber is elongated and connected into inflation sections through an air pipe system, and the air chamber of one inflation section is arranged alternately with the air chamber of another inflation section, wherein each inflation section is pneumatically connected to its corresponding valve outlet, and the valve is controlled by a controller so as to alternately inflate and deflate the air chamber, thereby generating a pressure wave, and the inlets of all valves are connected to the outlet of the air pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 An air cushion pneumatic circuit with three inflatable sections is shown by way of example, wherein:

[0010] 1- first inflation section air chamber;

[0011] 2- Second inflation section air chamber;

[0012] 3- the third inflation section air chamber;

[0013] 4- First inflation section valve;

[0014] 5- Second inflation section valve;

[0015] 6-the third inflation section valve;

[0016] 7- Air pump;

[0017] 8- Air duct system. DETAILED DESCRIPTION

[0018] Here's how the air cushion works.

[0019] like Figure 1 As shown, the first inflatable section air chamber 1 is pneumatically connected to the outlet of the first inflatable section valve 4. The second inflatable section air chamber 2 is pneumatically connected to the outlet of the second inflatable section valve 5. The third inflatable section air chamber 3 is pneumatically connected to the outlet of the third inflatable section valve 6. The inlets of all valves are connected to the outlet of the air pump 7. The inlet of the air pump is connected to the air inlet (not shown), and the air inlet can be used as the inlet of the air pump. Air can be discharged from the air chamber through an exhaust valve (not shown) or an uncontrolled throttling method. For example, the air chamber material uses a breathable material, or a diaphragm (hole) is set in the air chamber or the air channel system (which can be a hose) to discharge air. The valve is controlled by a controller (not shown) according to a preset algorithm. For example, the controller can alternately open the valves to generate pressure "waves" to massage the lower buttocks and promote blood flow in the buttocks, or pump as much air as possible into certain air chambers within a certain period of time to put pressure on certain areas of the gluteal muscles, and then pump air into other air chambers, and deflate the air chambers that were previously pumped with air to transfer pressure to other areas of the gluteal muscles, thereby producing a massage effect, promoting blood flow in the buttocks area, and achieving a relaxing and soothing effect.

[0020] The number of the inflation sections can be two, three or more, so that consumers can choose the best solution according to specific circumstances.

[0021] The air cushion can be made into a rectangular, oval or circular shape, with a width of not less than 200 mm and not more than 1200 mm, and a length of not less than 200 mm and not more than 1200 mm. If the seat cushion is smaller than the above size, it will not completely cover the buttocks of the person when sitting, resulting in a reduced massage effect. The air cushion with a slender shape and meeting the size requirements can be conveniently placed on the back seat of a car for use by multiple passengers. The air compressor (i.e., air pump) of the air cushion can be powered by a battery, a power bank, a car USB power supply, or an aircraft USB power supply, so the air cushion can be carried with an inflatable neck pillow for convenient use during travel. The air compressor of the air cushion is similar to the air compressor in an automatic pressure gauge. This air compressor is small in size and easy to carry. The air cushion can be made of a thin and tough rubber material, which makes it easy to fold the air cushion after deflation and put it in a backpack or travel bag for carrying and use. The air chamber is slender, which can enhance the massage effect and also make the air cushion easy to fold and carry. For example, the air chamber may be an elongated rectangle, and the ratio of the length to the width of the air chamber is not less than 10:1. Preferably, the length-to-width ratio of the air chamber is 20:1.

[0022] The air cushion has a compact structure and a wide range of uses. It can be flexibly installed on the user's existing seats (such as chairs, armchairs or stools), thereby achieving the technical effect of massaging the buttocks of the user while sitting. With the massage function, the user can reduce the frequency of getting up and activities, relieve muscle tension in the buttocks area of ​​the user, and thus improve work efficiency.

[0023] Industrial Applicability: The air cushion can be manufactured using known techniques.
