Abstract
The invention discloses an improved chair. According to the invention, the chair comprises a backrest and a headrest arranged on the backrest. A slide bar is connected to the back of the headrest. A slide rail is arranged on the back side of the upper part of the backrest. A runner is arranged in the slide rail. The lower part of the slide bar is threaded in the runner, and the slide bar can slide up and down along the runner. The slide rail is provided with a locking mechanism for fixing the slide bar in the runner. A neck-rest is arranged on the backrest at the position below the headrest. The neck-rest is in a drum shape, and is rotatingly connected to the backrest. According to the invention, the headrest can slide up and down with the cooperation of the slide bar on the back of the headrest, the slide rail on the upper part on the back of the backrest, and the locking mechanism. An elastic steel sheet barb section is arranged on the top of the backrest, the headrest is subject to elastic deformation when a user rests on the headrest, such that the user is more comfortable. Also, the drum-shaped neck-rest is added, and is rotatingly connected to the backrest. When a user rests on the backrest, the neck receives natural massage, such that the user is more comfortable.
