Flexing frame applied to seat unit and seat unit

Abstract

The invention discloses a flexing frame applied to a seat unit and the seat unit, and belongs to the technical field of furniture. The flexing frame comprises a fixed bottom bar, a front supporting bar, a back supporting bar, a cushion plate, a backrest plate, at least one foot stool couch and a foot stool assembly, wherein the front supporting bar and the back supporting bar rotate in a vertical plane, the cushion plate and the backrest plate are arranged at the top of the front supporting bar and the top of the back supporting bar and are connected, and the foot stool assembly is used for stretching and retracting the at least one foot stool couch; the bottom end of the front supporting bar is hinged at the front end of the bottom bar, the bottom end of the back supporting bar is hinged at the back part of the bottom bar, the top end of the front supporting bar is hinged with the foot stool assembly, the top end of the back supporting bar is connected with the back end of the cushion plate through a first connecting rod, and a first transmission part and a second transmission part which are mutually matched are respectively arranged at the back end of the cushion plate and the top end of the back supporting bar. The flexing frame applied to the seat unit and the seat unit, which are provided by the invention, have the advantages that the whole structure is simple, components are a few, the mounting efficiency is high, and the production costs are effectively reduced; mutually matched driving tooth and driven tooth are arranged between the cushion plate and the back supporting bar, so that the whole device runs smoothly and stably, and the use stability is great.

Description

technical field [0001] The present invention relates generally to sports upholstered furniture for supporting the body of a user in a substantially sitting-stand position, including recliners, armchairs, sofas, couple seats, modular furniture, theater seats, traditional chairs, and Chairs with movable seats, these pieces of furniture are generally referred to herein as "seating units"; Seat unit with telescoping frame.

Problems solved by technology

[0004] But generally speaking, the structure of these seat units is different in complexity, but if a more comfortable sitting feeling is required during exercise, a relatively complicated linkage mechanism is required to give this function; this makes the structure of the seat unit more complex. Complex, bulky and heavy, low position accuracy, high production cost, and inconvenient to carry
