Description

A breathable cushion

technical field

The invention belongs to the field of seat accessories, and in particular relates to a breathable cushion.

Background technique

The sofa seats on the market are soft and comfortable, but sitting on them for a long time will cause the user's buttocks to feel uncomfortable due to the airtightness. lesion.

Cars are very popular at present, and in developed cities and towns, there are basically one or several cars per household, and going out by car is also a part of life. Although most cars are equipped with air conditioners, due to the limitation of space, the ventilation at the bottom of the seat and the back is still insufficient. After sitting for a long time, the buttocks and back of the passengers will be hot and sweaty.

With the continuous improvement of transportation hubs, the distance people travel has become longer and the frequency of travel has become higher. Long-distance buses, ordinary trains, high-speed trains and high-speed rails have become the means of transportation that people often take. The sweat and discomfort caused by the airtight cushion.

Drivers of various vehicles basically sit at work, not only the waist is prone to fatigue, the seat cushions are not breathable, but the buttocks are also tortured.

To sum up, the seats and cushions in the prior art are not breathable enough, so that the user's buttocks are kept in a stuffy and wet situation for a long time, which makes the user feel uncomfortable. In severe cases, the skin of the buttocks may suffer from lesions.

Contents of the invention

Purpose of the invention: to solve the problems of airtight seat cushions and low user comfort in the prior art.

In order to solve the above problems, the present invention designs a breathable cushion, which has good air permeability, simple structure, strong practicability and high comfort. Its technical scheme is as follows:

The invention relates to a breathable cushion, which comprises a top layer, a bottom layer, a spring, a movable support structure and an air bag structure.

The top layer has a breathable structure corresponding to the air outlet of the airbag. When the internal volume of the airbag changes and the gas is ejected or inhaled, the gas on the upper and lower surfaces of the top layer is promoted to circulate more, and the air permeability of the cushion is improved.

The bottom layer, located at the bottom of the breathable cushion, is used to support the movable support structure, spring and air bag structure.

The spring is located between the top layer and the bottom layer, and is at least connected to one of the top layer, the bottom layer, the movable supporting structure and the airbag structure. When the distance between the top layer and the bottom layer changes, the spring is subjected to a force, driving the top layer and the bottom layer to return to the state of the minimum distance of the spring force.

The movable supporting structure is located between the top layer and the bottom layer, and is at least connected with one of the top layer, the bottom layer, the spring and the air bag structure. Its shape can be a point-shaped support shape, so that the top layer and the bottom layer can approach or move away from each other in areas other than the support points; Away; it can also be a cross-shaped support shape, so that the top layer and the bottom layer can be close to or far away from each other in the gap area of the cross support lines. Movable support and as optional structure, non-essential structure of the present invention.

The airbag structure is located between the top layer and the bottom layer, and is connected with at least one of the top layer, the bottom layer, the spring and the movable supporting structure. The airbag structure includes an airbag air outlet corresponding to the top-layer breathable structure. When the internal volume of the airbag structure changes and the gas is ejected or inhaled, the gas flow near the top layer is increased, so that the user feels that the buttocks are ventilated and the comfort level is improved. .

When the distance between the top layer and the bottom layer becomes smaller, the internal volume of the airbag structure becomes smaller, and the gas stored inside is squeezed out from the outlet of the airbag; when the distance between the top layer and the bottom layer becomes larger, the internal volume of the airbag structure becomes larger, and the airbag structure Inhale gas inside.

The working principle of the air-permeable cushion of the present invention: the user sits on the cushion of the present invention and shakes, so that the distance between the top layer and the bottom layer changes, and the internal volume of the airbag structure changes between two states of becoming larger and smaller, making the airbag structure The gas is sprayed or inhaled near the top layer, which promotes the flow of gas near the top layer and improves the air permeability of the cushion.

When the present invention is used on fixed seats such as offices, as long as the user shakes the seat cushion once in a while, the buttocks can be ventilated. When used on cars or other vehicles, because the vehicle itself is in the process of shaking, it is not necessary for the user to actively shake the seat cushion. If the user actively shakes it again, it will be more conducive to ventilation and improve the comfort of the user.

The present invention can select part of the structure and implement it on the seat, so that the seat has the ventilating function of the seat cushion of the present invention.

The structure of the air-permeable cushion of the present invention is also suitable for back cushions and mattresses.

To sum up, the present invention has a simple structure, effectively improves the ventilation of the seat cushion, has strong practicability and high comfort, and is suitable for use on various seats.
