Abstract

The invention discloses a sofa extension support and a sofa. The sofa extension support comprises a base, extension assemblies and a seat frame, wherein the extension assemblies are connected with thebase; each extension assembly comprises a side plate, a leg mechanism and a support assembly, wherein the leg mechanism comprises a connecting rod assembly and a main foot rest piece which are connected by six connecting rods in a crossed mode, and the connecting rod assembly drives the main foot rest piece to stretch or retract; the seat frame is arranged on the side plates, and the height fromthe highest point of the seat frame to the ground is smaller than 28 cm. The extension length and height of the connecting rod assemblies are increased, the distance between the connecting rod assemblies and the ground is larger in the moving process, the distance between the seat frame and the ground is smaller, and comfort is higher after soft packing.

Description

technical field [0001] The invention relates to the technical field of functional sofa manufacturing, in particular to a sofa extension bracket and a sofa. Background technique [0002] Functional sofa refers to a multi-functional sofa, which can adjust the seat angle and headrest angle to meet the different needs of the body for different sofa angles at different times. Compared with sofas without functional seats, it is more humane. Even some rocking chair functional sofas can rock back and forth, which is very comfortable. At the same time, there can also be functional sofas or seats with massage, zero gravity, etc. that are of great benefit to health. [0003] In the sofa with an extension function, the legs realize the expansion and contraction of the leg rest assembly through a telescopic link mechanism. Generally, the extension range of the link mechanism is limited, and the footrest extends out from under the seat frame according to a relatively constant arc during ...
