Problems solved by technology

[0004] However, the backrest mechanism described in Patent Document 1 is a structure in which the angle of the seat portion is fixed and only the backrest is laid down. The seat portion protrudes forward a lot, which increases the occupied area of ​​the chair as a whole. The problem of unusable space
In addition, since the position of the shoulders on the backrest is changed when the backrest is erected and laid down, when it is used in a massage chair, even if the position of the shoulder to be massaged is adjusted, the angle of laying down will change accordingly. offset problem

Abstract

The chair comprises: a chair body having a seat surface part and the backrest part and a support part for supporting the chair body, and the reclining mechanism which moves the backrest part forward simultaneously with the backward falling in a state where an angle between the seat surface part and the backrest part is fixed constant is arranged between the support part and the chair body. To provide a chair having a reclining mechanism, by which an occupancy area is reduced as much as possible, while preventing the backward protrusion of a backrest part in the case of reclining and the contact position with a body such as shoulders is not changed.

Description

technical field [0001] The present invention relates to chairs suitable for massage chairs and the like, in particular to a backrest mechanism. Background technique [0002] In conventional chairs having a backrest mechanism, when the backrest is laid down, the backrest protrudes farther back than when the backrest is upright. Therefore, when placing the backrest close to the wall, it is necessary to anticipate the state in which the backrest is reclined and set a distance from the wall. [0003] In order to prevent such a backrest protruding backward, Patent Document 1 proposes to slide the lower part of the backrest and the seat part forward along the bracket when the backrest is laid down. [0004] However, the backrest mechanism described in Patent Document 1 is a structure in which the angle of the seat portion is fixed and only the backrest is laid down. The seat portion protrudes forward a lot, which increases the occupied area of ​​the chair as a whole. The problem...
