Description

Apparatus for Adjusting Shape of Seat}

The present invention relates to a sheet shape adjusting device.

Modern people spend a lot of time sitting on chairs, so it is important to sit with the correct posture for the health of the spine and lower back. The structure of the chair consists of legs, a seat that touches the buttocks of the body, and a backrest that is connected to the seat and supports the waist. The legs of the chair are manufactured to be adjustable in various sizes to suit the individual user's height or sitting height. The backrest of the chair is also made of an elastic material or is made to fit the individual user's waist through a deformable structure. However, in the case of most seat boards sold on the market, the size and shape of the seat where the buttocks of the individual user's body parts come into contact are fixed at a constant level.

The body structures of users who use chairs are all different, and in particular, the size and shape of the buttocks are different. As a result, a problem arose in which individual users had to adjust their body structure to the predetermined size of the seat when sitting on a chair. In this process, when an individual user sat on a chair, problems such as poor posture and bending of the spine and waist occurred. there was.

To solve this problem, Republic of Korea Patent Publication No. 10-1706126 is an invention related to a seat for posture correction, which has the feature of providing a customized seat to each user by allowing the seat to move forward, backward, left, and right. Begin. However, since only a configuration for moving two seat plates is disclosed, there is a problem in that there is a limitation in adapting the seat plate to the user's body structure.
