Description

Chair back cushion

Technical field

The utility model belongs to daily living article field, relates in particular to a kind of Chair back cushion.

Background technology

Existing Chair back cushion, is generally divided into two kinds of warming-type and cold-type yellow (clear)s: the back cushion radiating effect of warming-type is bad, and gas permeability is poor, easily breed bacteria; The back cushion of cold-type yellow (clear) only can use in summer, and sweat is easily residual, uses very uncomfortable.In addition, as the personnel of the special occupation such as student, driver, need long-term seating, itself is just easily tired, if seat is uncomfortable, that back leans on is nonelastic, do not meet human physilogical characteristic, more easily aggravates dependence personnel's fatigue.

Utility model content

For addressing the above problem, the utility model provides the Chair back cushion of a kind of good permeability, comfortable, easy to clean, is applicable to the long-term personnel that keep sitting posture such as clerk, student and long-distance car driver.

Chair back cushion described in the utility model, comprises the 3D scrim layer and the air cushion that be arranged in parallel, and the one or both sides of 3D scrim layer are provided with nylon suede band, and air cushion is provided with the nylon of working in coordination with described nylon suede band and hooks band.

When use, air cushion and 3D scrim layer are bonded together by velcro, 3D scrim layer directly contacts people's back, adhesive multilayered air cushion or 3D scrim layer as required, increase gas permeability and comfortableness, the 3D scrim layer of contact human body back can be used two sides to be all provided with the structure of nylon suede band, can change as required back and lean on face, and nylon suede band contact people's back, can not scratch clothes; When cleaning, velcro is opened and can be realized separating of 3D scrim layer and air cushion, after separating, directly clean.

Air cushion comprises independently air bag of the edge sealing of inverted U and two: air bag A and air bag B, air bag A is positioned at inverted U edge sealing blind end, air bag B is positioned at the openend of inverted U edge sealing, and the external boundary of inverted U edge sealing and air cushion forms an enclosed cavity, passes through flanging interval, border between air bag A and air bag B.

Preferably, border flanging is V-arrangement.

Preferably, air bag A is fan-shaped.

Preferably, air bag B is M type.

The below of air bag A and air bag B is equipped with charge valve.

Air cushion adopts this structural design to meet human physilogical characteristic, air bag B is that waist leans on position, suit the feature of backbone, give backbone to support, fatigue-relieving, air bag A is positioned at shoulder, air cushion and 3D scrim layer good springiness, comfortable flexible when dependence, lean on for a long time indefatigability, can manually inflate as required, in the time not using, also can gas be bled off and be deposited by charge valve simultaneously.

Preferably, the nylon on air cushion hooks to be with and is arranged on described inverted U enclosed cavity.

Preferably, 3D scrim layer adopts bound edge material bound edge, and nylon suede band is arranged on bound edge.

Compared with prior art, the utility model has the advantages that:

1,3D scrim layer good permeability, is difficult for producing peculiar smell and breed bacteria, clean hygiene;

2,3D scrim layer good springiness, can increase comfort when use, and the structure of air cushion meets ergonomic designs, and long-term dependence also can ensure comfortableness, indefatigability;

3, between 3D scrim layer and air cushion, connect by velcro, convenient disassembly, is convenient to change 3D scrim layer or air cushion, is convenient to clean;

4, air cushion is connected by velcro with 3D scrim layer, and simple in structure, production cost is low;

5, can apply and multiple occasion, be particularly useful for needing the long-term personnel that keep sitting posture, as student, the personnel etc. that drive over a long distance, when use, directly back cushion is placed on the chair back side, easy to use.
