Problems solved by technology

Even if there are leisure chairs with the function of reclining the backrest in the existing market, the angle of reclining the backrest is very small. Their method is to open a gap at the back of the armrest, and use the gap where the backrest presses the armrest when it is tilted backward. Deformation provides a narrow space for the backrest to fall back, but the angle of the backrest of this leisure chair is very small

Embodiment Construction

[0062] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0063] First define the reference orientations of the components of the present invention. In the present invention, when the seat or seat is installed and used normally, the front of the seat is the front end and the front part, and the rear of the seat including the position of the backrest is the rear end and the rear part. .

[0064] Such as Figure 1 to Figure 9 A seat back and armrest synchronous linkage mechanism is shown, the mechanism includes a tray mechanism 1 , a backrest support 2 , a seat frame support 3 and a rear enclosing armrest 4 . The rear enclosing armrest 4 is generally used on sofa chairs or leisure chairs. It is different from traditional armrests in that the rear enclosing armrest 4 wraps the rear of the seat and the two sides of the seat from the rear of the seat to both sides. If there is no backrest,...

Abstract

The invention relates to a seat backrest and armrest synchronous linkage mechanism. The seat backrest and armrest synchronous linkage mechanism comprises a tray mechanism, a backrest bracket, a seat frame bracket and a rear surrounding-type armrest; the lower end of the backrest bracket is connected to the rear end of the tray mechanism, the seat frame bracket is mounted on the tray mechanism andmoves along with the shape change of the tray mechanism, the front end of the rear surrounding-type armrest is hinged to the two sides of the seat frame bracket separately, and armrest sliding grooveparts are mounted in the two sides of the rear end of the rear surrounding-type armrest and slidingly connected with the two sides of the lower end of the backrest bracket through an armrest rotatingshaft; when the backrest bracket inclines backwards around the armrest rotating shaft, the tray mechanism deforms, the front end of the seat frame bracket is upwarped under the function of the tray mechanism, and the front end of the rear surrounding-type armrest is driven to be upwarped simultaneously; meanwhile, the armrest rotating shaft slides in the armrest sliding groove parts to drive the rear end of the rear surrounding-type armrest to rotate backwards. Through the design, the rear portion of the rear surrounding-type armrest does not hinder the backward inclination of the backrest, and the defect that the backward inclination angle of seat backrests of the type on the market is small is broken through.

Description

technical field [0001] The invention belongs to the technical field of furniture, and in particular relates to a synchronous linkage mechanism of a seat back and an armrest and a seat. Background technique [0002] At present, a large part of the armrests of leisure chairs on the market are made into the style of rear enclosure. Most of the armrests are integrated with the backrest, and the backrest does not have the function of tilting up, which brings certain problems to the comfort of people. Even if there are leisure chairs with the function of reclining the backrest in the existing market, the angle of reclining the backrest is very small. Their method is to open a gap at the back of the armrest, and use the gap where the backrest presses the armrest when it is tilted backward. Deformation provides a small space for the backrest to fall backward, but the angle at which the backrest of this leisure chair falls is very small. Contents of the invention [0003] In order...
