Description

Human engineering sofa capable of being adjusted in multiple sections Technical Field The invention belongs to the technical field of sofas, and particularly relates to an ergonomic sofa capable of being adjusted in multiple sections. Background The traditional sofa design adopts fixed knot to construct more, and its back angle, handrail height and foot rest position are not adjustable, are difficult to adapt to different body type user's demand. When the sofa with a fixed angle is used for a long time, the waist, the neck and the legs of a user are easy to be tired due to uneven pressure distribution, and even muscle strain or spinal deformation is caused. The existing adjustable sofa can realize partial function adjustment through a manual knob or a mechanical connecting rod, but is complex to operate and cannot realize multistage fine control. In terms of function expansibility, the conventional sofa lacks a support expansion design in a lying mode. When a user needs to lie down for rest, the fixed structure of the armrests and the backrest limits the stretching space, and the whole body relaxation requirement cannot be met. For this purpose we propose an ergonomic sofa that can be adjusted in multiple sections.
