Abstract

The invention relates to the field of functional sofas, in particular to a functional sofa stretching device with good supporting performance, which comprises a base, a sitting part, a backrest part, a leg supporting part, a driving part, a linkage assembly and a supporting assembly, the linkage assembly is used for driving the leg supporting part to rotate relative to the sitting part along with the driving of the driving part so as to form a sitting posture, a TV posture and a lying posture; the supporting assembly is connected with the base and the linkage assembly, the supporting assembly is a connecting rod mechanism, a limiting plate is arranged on one connecting rod of the supporting assembly, and a limiting structure used for supporting the supporting assembly in the sitting posture, the TV posture and the lying posture is arranged between the limiting plate and the base. When the sofa stretching device is in any one of the sitting posture, the TV posture and the lying posture, the end, close to the leg supporting part, of the sitting part can be supported by the limiting structure after force transmission through the linkage assembly and the supporting assembly, and therefore the problems that the end, close to the leg supporting part, of the sitting part is insufficient in supporting force and prone to sinking are solved. The stability of the sofa stretching device is improved.

Description

technical field

[0001] The present application relates to the field of functional sofas, in particular to a stretching device for a functional sofa with good support. Background technique

[0002] At present, functional sofas with adjustable posture are widely used. In the existing armrest landing link type functional iron frame, since the connection point between the entire seat and the base is close to the backrest, especially after the footrest is stretched, there is often insufficient support at the end of the seat near the footrest, which is easy to sinking problem. That is, the support for the pedal part is not enough.

[0003] With regard to the related technologies mentioned above, the inventor believes that there is a defect that the end of the seat part near the pedal part has insufficient support force and is easy to sink. Contents of the invention

[0004] In order to improve the stability of the stretching device,

[0005] A functional sofa stretching devi...
