Description

Folding chair

Technical Field

The utility model relates to the field of seats, in particular to a folding chair.

Background

The folding chair has the characteristics of portability and foldability, is convenient to carry and saves space, and is widely applied to various public places or is convenient to carry as an outdoor chair. The common folding chairs comprise a chair frame and chair cloth connected with the chair frame, the chair frame can be folded integrally, a backrest is also arranged in a plurality of folding chairs, and a backrest rod and backrest cloth which can be unfolded and folded simultaneously are added in the chair frame.

In many folding chairs in the prior art, the folding chair comprises a folding chair frame which is arranged in front of two upright backrest pipes, and the folding chair has the defects that the backrest pipes are straight rods, and the straight backrest of the folding chair cannot well support the waist of a person because the spine of the human body is curved, and can not realize certain leaning action according to the use requirement in sitting. Therefore, the folding chair is convenient to fold, but is uncomfortable to use, and cannot enable a human body to have good rest and relax. Therefore, there is a folding chair in which the backrest bar is formed to be inclined backward, but the backrest bar is merely a straight bar structure inclined backward, such as a folding chair of the backrest of chinese patent application No. 99237796.X, and the folding chair also needs to position the inclined backrest upright.

Therefore, many folding chairs or beach chairs use a back bar that is inclined rearward, and the back of the back bar is generally required to be connected to a rear leg bar that is inclined forward to support the back bar, such as a beach chair frame of chinese patent application No. 200920138004.0. For the folding chair, the backrest rod piece is still only a straight rod, and the upper part serving as the backrest is only parallel to the lower supporting leg part, so that a certain inclination is required to be kept, and therefore, the elevation angle of the backrest is fixed to be a certain angle, so that comfortable leaning cannot be achieved, and the folding chair is poor in seating comfort. The backrest rod is a straight rod which is inclined backwards, and when the folding chair is folded, the rod piece is possibly not compact enough after being folded, and the volume is enlarged. Furthermore, the front side of the seat is only provided with a pair of crossed struts, so that the structural stability is poor, when a user rises from the seat, the center of the seat is easy to incline forwards, and the user can fall forwards, so that potential safety hazards are caused.
