Abstract

The invention relates to the technical field of frameworks of sofas, in particular to a back lying type folding sofa frame. The back lying type folding sofa frame comprises an underframe, a transmission rod, a driving device and two folding telescopic mechanisms; the driving device is connected to the underframe; an output end of the driving device is hinged to the transmission rod; the two folding telescopic mechanisms are correspondingly arranged at the two ends of the transmission rod and symmetrically arranged; the driving device is used for driving the transmission rod to rotate and/or move, so that the two folding telescopic mechanisms extend or retract; and the folding telescopic mechanisms comprise connecting plates, leg telescopic components, leg bearing frames, connecting components, back telescopic components and back bearing frames. The back lying type folding sofa frame provided by the invention has the advantages that the leg bearing frames are upturned to a higher position and the back bearing frames are closer to the ground to provide a perfect fitting and supporting for the whole body of a person when the back lying type folding sofa frame is in a lying state; thegravity force of the person is uniformly dispersed to each part of the sofa frame, so that the person enjoys a zero-gravity state to enable the body to be further relaxed conveniently.

Description

technical field [0001] The invention relates to the technical field of sofa skeletons, in particular to a back-flat folding sofa frame. Background technique [0002] With the gradual improvement of people's living standards, electric sofas, as a kind of life enjoyment, have increasingly entered the homes of ordinary people. Compared with traditional sofas, electric sofas are more comfortable and functional due to their unique , is more and more loved and respected by people. The traditional electric sofa cannot be completely in the zero-gravity state when it is in the lying position, that is, the leg support frame is not high enough, and the back is not close enough to the ground to allow people to relax further. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a flat-back folding sofa frame. When the back-flat folding sofa frame is in a lying position, the leg support brackets are tilted higher, and the back sup...
