Abstract

The invention discloses an armrest synchronous lifting link mechanism which comprises a backrest, a seat frame, an armrest, a rotating shaft and a link device, wherein the link device comprises a rotating part, a fixed part and a connecting part; the fixed part is fixedly arranged on the seat frame; the rotating shaft sleeves the backrest; one end of the rotating part sleeves the rotating shaft and the other end is arranged on the fixed part; the backrest is connected to the seat frame by virtue of the rotating part; the armrest sleeves the rotating shaft; and one end of the connecting part is connected to the armrest and the other end is connected to the fixed part. According to the armrest synchronous lifting link mechanism disclosed by the invention, the armrest lifts when the backrest is rotated, and under the action of the link device, the armrest is constantly parallel with the seat frame; so that, the link mechanism is convenient in using.

Description

technical field [0001] The invention belongs to a main part of a seat, in particular to an armrest synchronous lifting linkage mechanism. Background technique [0002] Most of the existing seat armrests are fixedly installed on the seat frame, so that the armrest is always parallel to the seat frame, that is, parallel to the horizontal plane, which is convenient for the placement of the user's hands. However, when the backrest tilts backward and downward, the upper body of the human body is driven to tilt backward, and the distance between the hands and the armrest is far away. At this time, the user's hands are difficult to place on the armrest, which is inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide an armrest synchronous lifting linkage mechanism, which can solve at least one of the above problems. [0004] According to one aspect of the present invention, an armrest synchronous lifting linkage mechanism is pro...
