RU220122U1 - AIR CUSHION FOR SEAT - Google Patents

Abstract

The utility model relates to cushions placed on the seat of a chair, armchair, or stool. The technical result is the ability to massage the buttocks while the user is sitting, especially when sitting at a computer, when a change in body position is not required during work, reducing congestion in the gluteal region, increasing productivity by reducing the frequency of warm-up, and also reducing the suffering of users for due to the use of air bags during long flights or traveling in a sitting position, where there is no opportunity to stand up and warm up. The technical result is achieved by the fact that an air cushion containing air chambers (located in the landing part above the base of the seat), a controller with valves (made with the ability to control the level of inflation of the air chambers), a pump, a system of air channels, is characterized by the fact that the air chambers can be made in the form of elongated or other geometric shapes (round, elliptical, etc.) and connected into inflatable sections, with the chambers of one section interspersed with the chambers of another section. The number of sections can be two, three or more. The air spring can be rectangular, rounded or round in shape, with a width of at least 200 and no more than 1200 mm, and a depth of at least 200 and no more than 1200 mm. The air spring compressor can be powered by batteries, a power bank, or USB power from the on-board power supply of a car or aircraft.

Description

The utility model relates to cushions placed on the seat of a chair, armchair, or stool.

Known for "Inflatable mattress and air supply with switching valve" US 5243721 [2], containing: a plurality of inflatable sections under a flexible shell; a pump, a plurality of switching valves, each switching valve being connected to at least one of said inflatable sections.

The disadvantage of the known solution is the impossibility of placing this product on a chair, a chair for massaging the buttocks while a person is sitting, and this product cannot be taken with you on the road for use on the go.

The closest to the claimed technical solution is “VEHICLE SEAT” RU 2697175 [1], containing: air chambers located in the landing part above the cushion material above the base of the seat; a controller with valves configured to individually control the inflation level of each of the air chambers between uninflated, partially inflated and fully inflated levels, an inflation system comprising a pump and a plurality of target air bypass channels.

The known device allows a person to sit.

The disadvantages of the method include the impossibility of using it in everyday life, for example, when working sedentarily at a computer, the impossibility of local massage of the sciatic area to eliminate congestion in it, leading to the need to get up frequently to warm up.

The technical result is obtaining the possibility of massaging the buttocks while the user is sitting, especially when sitting at a computer, when no change in body position is required during work, reducing congestion in the gluteal region, increasing productivity by reducing the frequency of warm-up, as well as reducing the suffering of users due to the use of air bags during long flights or traveling in a sitting position, where there is no opportunity to stand up and warm up.

The technical result is achieved by the fact that a pneumatic cushion for a seat containing air chambers (located in the landing part above the base of the seat), a controller with valves (made with the ability to control the level of inflation of the air chambers), a pneumatic pump, a system of air channels, is characterized by that the air chambers are made elongated and connected into inflatable sections through a system of air channels, and the chambers of one section are interspersed with the chambers of another section, while each section is pneumatically connected to its own valve at the outlet, which are controlled by a controller, to allow alternate inflation and deflation of the chambers, creating a pressure wave, with all valves at the inlet connected to the outlet of the air pump.

Implementation

The figure shows an example of a fragment of a pneumatic circuit, a proposed air spring with three sections, where:

1 – chambers of the first section;

2 – chambers of the second section;

3 – chambers of the third section;

4 - valve of the first section;

5 – valve of the second section;

6 – valve of the third section;

7 – pneumatic pump;

8 – air channel system.

The device operates as follows.

The chambers of the first section 1 are pneumatically connected to the output of the valve of the first section 4. The chambers of the second section 2 are pneumatically connected to the output of the valve of the first section 5. The chambers of the third section 3 are pneumatically connected to the output of the valve of the first section 6. The inputs of all valves are connected to the output of the pneumatic pump 7. Input The pump is connected to an air intake (not shown), which can serve as the inlet of an air pump. The release of air from the chambers can be done either using exhaust valves (not shown) or using uncontrolled throttling - the release of air from the chambers, for example, using air-permeable materials for the chambers, or by installing a diaphragm (hole) in the chamber itself or in the air system channels, which can be used as flexible tubes. The valves are controlled by a controller (not shown) according to a given algorithm. For example, the controller can alternately turn on the valves, creating a “wave” of pressure, massaging the lower part of the buttocks, creating additional blood flow into them, or pump some chambers to the maximum for a certain period of time, thereby creating a load on a certain area of the gluteal muscles, then pump up other chambers, and deflate the previous ones, thus moving the load to another area of the gluteal muscles, thereby creating a massage effect and the possibility of a more uniform blood supply to the entire buttock area.

The number of sections can be two, three or more, which will allow you to select optimal conditions for the consumer.

The air spring can be rectangular, rounded or round in shape, with a width of at least 200 and no more than 1200 mm, and a depth of at least 200 and no more than 1200 mm. On a pillow smaller than the specified dimensions, the effectiveness will decrease due to incomplete coverage of the gluteal part of the seated person. A pillow of elongated shapes and sizes will be convenient for use in the back seat of a car for several users. The air bag compressor can be powered by batteries, a power bank, or USB power from the on-board power supply of a car or airplane, thanks to which the air bag can be taken with you on the road just like inflatable tourist neck pillows. Compressors of similar types can be seen in automatic blood pressure monitors.

The technical result of obtaining the possibility of massaging the buttocks while the user is sitting is achieved by the compactness and versatility, as well as the mobility of the device, applied to the user’s existing seat, for example, a chair, armchair or stool. Gaining the option of massage increases productivity by reducing the frequency of warm-ups and reduces congestion in the user's gluteal region.

Industrial applicability. The device can be manufactured using known technologies.
