Description

  The present invention relates to a chair, and more particularly, to a seat portion of a chair including an airbag and a backrest thereof, which includes an airbag, supports a waist and a buttock, and corrects a posture.

  Currently, products such as cushions that support a specific part of the human body, support the body, and adjust the body shape are commercially available. In addition, a plurality of techniques have been patent-applied for such techniques. These products, or related technologies, are designed with an emphasis on whether the appearance is ergonomic or not. Furthermore, with this as a requirement, the shape of the seat is made to be a shape along a specific part of the human body, for example, the buttock, in order to closely contact the specific part of the human body such as the buttock. For this reason, when a user hangs on a chair for a long time, the pressure which a buttocks receives is distributed to a seat part, and the effect of adjusting a user's body shape including parts, such as a buttocks, is achieved.

  However, although the conventional technique described above achieves the effect of distributing the pressure and adjusting the body shape by matching the seat to the shape of the buttock, it has at least the following drawbacks. That is, the conventional technique achieves the effect of distributing pressure and adjusting the body shape by a structure suitable for ergonomics, but cannot perform local adjustment according to the individual needs of the user. Therefore, the effect of pressure dispersion is limited. As an ideal design, it is necessary to be able to adjust to the shape of its own buttock according to the needs of the individual user, and the most preferable effect of pressure dispersion can be achieved by such adjustment.

  In addition, the conventional technique is only in close contact with a specific part such as a buttocks, for example, and lacks a supporting force. When a large pressure is applied to the buttocks of the human body, a deformation that can support this occurs. For this reason, the conventional technique is not preferable in that it supports a specific part of the human body and adjusts the body shape.

In addition, when the pressure is simply distributed only to the buttocks and the body shape is adjusted, the purpose of correcting the posture and adjusting the body shape can be achieved only by extending the back and hanging it on the seat. However, the waist is not designed to correct posture. Generally, when the user sits on the seat for a long time, the user leans on the backrest and tries to reduce the burden on the waist. However, in general chairs including the above-described conventional technology, a special design for the backrest and ergonomics is not made. For this reason, even if a special design is applied to the seat, the posture becomes worse and the original effect is lost.

  Furthermore, as described above, when the user leans on the backrest, the seat easily shifts forward. When the seat is displaced forward, the posture is further deteriorated, and the result is the opposite of the expected effect of the main body to correct the body shape and correct the posture. For this reason, the position of the seat portion must always be adjusted. Therefore, it is preferable that the seat back is provided with a backrest having an effect of adjusting the posture. With such a structure, it is possible to prevent the seat portion from being displaced and the resulting poor posture.

  Therefore, it can not be said that the conventional chair with the effect of supporting a specific part of the human body, supporting the body, adjusting the body shape and correcting the posture has yet reached the ideal range, Improvement is desired.

  An object of the present invention is to provide a seat portion and a backrest that supports the buttocks, has the effect of adjusting the body shape, and has the preferable effect of correcting the posture.

  Therefore, as a result of intensive studies in view of the prior art, the inventor has at least one air bag and at least one lower connecting pipe at one end and at least one end at one end. A seat back and a backrest provided at one end of the seat portion where the lower connection tube is provided. The seat portion and the backrest are inserted into the upper connection tube. The present invention has been completed on the basis of such knowledge, and that the deficiency of the conventional technique can be improved by the seat portion formed by connecting the two and the backrest thereof.

  This device will be specifically described below. The seat portion including the airbag disclosed in claim 1 and the backrest thereof include at least one airbag, and at least one lower connecting pipe at one end and at least one end. A seat back and a backrest provided at one end of the seat portion where the lower connection tube is provided. The seat portion and the backrest are inserted into the upper connection tube. And connected.

  According to a second aspect of the present invention, the seat portion including the airbag and the backrest thereof have a plurality of engaging holes formed in the upper connecting pipe in the first aspect, and the lower connecting pipe is fixed to the lower connecting pipe. An engaging means comprising a hollow fixed tube, an elastic body provided in the fixed tube, and an engaging ball is provided, and the engaging ball is elastically elastic, and a part of the spherical surface is connected to the fixed tube. When the height of the backrest is adjusted by providing the protruding portion of the engaging ball in the state protruding from the lower connecting pipe and engaging the engaging hole of the upper connecting pipe, the lower connecting pipe and the The upper connecting pipe is configured to be locked.

  The seat portion including the airbag and the backrest thereof according to claim 3 are provided with an elastic body for assisting the gas to be injected into the airbag according to claim 1 and maintaining the shape of the airbag. A valve body is provided through a gas flow pipe, and the opening and closing of the valve body is controlled to control the injection or discharge of gas into the airbag, so that the airbag has a predetermined altitude. And the shape is fixed.
