Abstract

The invention discloses a multifunctional chair. The multifunctional chair comprises a base, a back connecting piece and a chair seat assembly, supporting rods extending upwards are arranged on the two sides of the rear end of the base respectively, and each supporting rod is rotationally provided with a back connecting piece. Seat supporting pieces are correspondingly arranged on the two sides of the rear end of the chair seat assembly, and the seat supporting pieces are rotationally connected to the back connecting piece so that the chair seat assembly and the back connecting piece can form linkage; a sliding guide mechanism is arranged between the front part of the chair seat assembly and the base and comprises an inclined guide groove formed in the chair seat assembly in the front-back direction and a guide block which is correspondingly arranged on the base and is in sliding fit in the inclined guide groove; from back to front, the inclined guide groove is inclined towards the front upper part; the back connecting piece rotates relative to the supporting rod and synchronously drives the seat supporting piece to rotate, and the chair seat assembly slides forwards relative to the base and is lifted upwards. According to the seat, the driving force applied to the back connecting piece when a user leans backwards and the restoring force for resetting of the seat assembly form a confrontation relationship, so that users with different weights feel comfortable when using the seat.

Description

technical field [0001] The invention relates to the field of seats, in particular to a multifunctional seat. Background technique [0002] As an important office tool in daily office life, office chairs are directly related to the quality of people's work and life. At present, the human-machine size matching relationship between the backrest and the seat surface of most office chairs on the market has not been studied carefully; when the user is reclining, the backrest of the seat, especially the lumbar support, is separated from the waist of the human body, and the two directly form a suspended gap, resulting in The seat loses support for the human waist in the reclined state, which is what we commonly call "running the waist". The lack of effective support for the human spine leads to many sedentary health problems; The size matching relationship between the human body and the machine has not been carefully considered. When the user is reclining, the buttocks and the seat...
