The invention relates to an elastic swing seat with an adjustable backrest angle, which comprises an elastic steel plate, a backrest and a tripod, the backrest is provided with a backing plate, at least one elastic steel plate is fixed on the back of the backing plate, the backing At least one stopper fixedly connected to the elastic steel plate is arranged below the board, and at least one backrest angle adjustment mechanism connects the lower end of the elastic steel plate with the stand column, and the adjustment of the backrest angle is realized by the backrest angle adjustment mechanism. The present invention can realize the elastic swing of the chair back by arranging the elastic steel plate at the back lining plate of the backrest; and a backrest angle adjustment mechanism is arranged between the elastic steel plate and the stand column, and the inclination angle position of the backrest can be realized through the backrest angle adjustment mechanism Arbitrary adjustment of the backrest, so that the backrest is positioned at the adjusted angle position and can be swung in this position. In addition, the elastic swing seat has a simple structure and is easy to install.
Description
technical field [0001] The invention relates to a seat, in particular to an elastically swinging seat with a backrest. Background technique [0002] In order to improve the comfort of the seat, the seat back in the seat is usually provided in a form that can elastically swing. At present, the elastic swinging device of the backrest used in the seat with elastically swingable seat in public places is generally composed of a back connecting plate, a pressure plate, a spring steel, a lower connecting plate, and the bolts, nuts, washers, etc. used to connect these parts. The structure of the parts is relatively complicated, the installation is relatively troublesome, the production cost is relatively high, and the performance is relatively unstable. In order to solve the problems existing in the prior art, Patent Bulletin No. CN208064895U discloses a seat back elastic swing device, a backing plate is arranged in the seat back, an elastic steel plate is arranged behind the backi...
