Description

  The present invention relates to a seat for seating in which a user does not feel tired even if he / she spends a long time in a sitting position.

  Normally, when a person sits on a chair or the like and raises the upper body, the entire upper body is loaded near the buttocks, particularly in the vicinity of the left and right sciatic bones. This is because, in the sitting posture, the state where the load is concentrated and applied to the muscles around the pelvis continues, and the blood flow in the vicinity of the left and right sciatic bones is obstructed to accumulate waste products. In addition, when the user sits on a chair or the like, the user is forced to wake up the upper body for a long time, which places a burden on the lower back, so that the muscles in the vicinity of the lower back become stiff and cause back pain. On the other hand, humans can promote blood circulation by floating their buttocks in the sitting position or exercising by standing up and turning their hips, and also reduce fatigue due to sitting position by relaxing muscle stiffness. Has been reduced or eliminated.

  For this reason, if an operation such as lifting the buttocks while driving a car that continuously takes a sitting posture is performed, safe driving is hindered, and it is troublesome to stop and move the waist. Similarly, performing such movements and exercises during office work in which the sitting posture is continuously taken decreases work efficiency.

  Furthermore, disabled persons or elderly people who are forced to live in wheelchairs cannot change their position to promote blood circulation while sitting on a wheelchair or furniture chair, etc. There is also a problem that it occurs.

  The following are conventionally provided as seats or cushions for laying on a seating surface of a chair or the like against such accumulation of fatigue due to such a sitting posture.

  For example, a pelvic cushion that has a backrest portion and a seating portion, sandwiches the buttocks by a pair of side frames built in the seating portion, and tightens the pelvis by the pair of side frames, thereby correcting the pelvis. (Patent Document 1).

  In addition, a pair of airbags are built in the cushion body on which the user's buttocks are placed, and the pair of airbags are inflated and contracted, so that the user can sit without repeating the operation of standing or sitting. There has been provided a pelvic correction device that can effectively solve the stiff muscles as they are, and can effectively correct the distorted pelvis (Patent Document 2).
