Description
Technical field
The utility model relates to the technical field of the seat, in particular to a kind of ergonomics 3D waist support net chair.
Background technique
Ergonomics 3D waist support net chair good gas permeability and relaxes as a product indispensable in office furniture
Appropriateness, obtains liking for the majority of consumers.Ergonomics 3D waist support net chair is coming into vogue so far at the end of the 20th century, technique and material
Material has very big breakthrough, due to the particularity of ergonomics 3D waist support net chair material and technique, leads to ergonomics in the market
3D waist support net chair is high-end and the price of low side differs greatly, comfort level also big difference.How to simplify technique, improves comfort level
Problem is in the urgent need to address.
For example existing net chair makes that human body waist can be pushed up as far as possible in the middle part of the chair back, has to improve waist comfort level
Setting slide Lumbar, some improves chassis so that waist can be pushed up when human body reclining always, but these all cost compared with
Height, structure is complicated；Some carries out structural improvement to back frame, so that back frame waist designs for lordosis, stretching tight the screen cloth set in back frame can
To form the Lumbar of a lordosis, this spline structure is relatively simple, and top waist effect can be realized by the change of shape, but is used
Such moulding, due to the strain problem of screen cloth, screen cloth can be very loose among back frame, can thus reduce the bullet of screen cloth Lumbar
Property, top waist effect can give a discount, play reaction, screen cloth among back frame such as be made to be also at tensional state, need to be carried out by technique
Improvement, but this will increase complex degree of structure and cost.
