Abstract

The invention discloses an overall adjustable folding chair which comprises a chair frame, wherein a chair back is mounted on the chair frame, the bottom end of the chair back is connected with the chair surface, the left side and the right side of the chair frame are respectively connected with the lower part of the chair back through a first sliding pair, the sliding direction of the first sliding pair is tilted relative to the horizontal direction, a chair back support saddle is connected on the chair frame, the left side and the right side of the chair back support saddle are respectivelyconnected with the upper part of the chair back through a second sliding pair, the chair back and the chair surface slide in the fixed direction relative to the chair frame along the first sliding pair and the second sliding pair, and a positioning device used for regulating angles of the chair back and the chair surface relative to the chair frame is mounted on the chair back. The overall adjustable folding chair can simultaneously utilize the space in the front row and the back row when regulating the angle of the chair back, simultaneously regulate the angle of the chair surface along withthe chair back, ensure that the angle between the chair back and the chair surface is unchanged and further ensure the comfort of the seat.

Description

technical field [0001] The invention relates to a seat, in particular to an integrally adjustable foldable seat. Background technique [0002] At present, most of the angle-adjustable seats used in public transportation such as airplanes and trains, or public places such as movie theaters and theaters can only adjust the angle of the back of the seat. It is necessary to reserve a large space in the rear row, otherwise it will affect the normal use of the rear seats, and after the seat back is down, the angle between the seat back and the seat surface will increase, reducing the comfort of the seat . Therefore how to make full use of the space in front of the seat when adjusting the seat angle while ensuring the comfort of the seat is a technical problem that has not been solved by those skilled in the art. Contents of the invention [0003] The purpose of the present invention is to provide an integrally adjustable foldable seat, which can use the space of the front row...
