Abstract

The utility model discloses a double backrest of an air-permeable seat, which not only realizes good air permeability, but also considers the comfort when a human body takes a seat. Two backrest shafts are symmetrically arranged on a combined backrest bracket, wherein each backrest comprises a bottom plate layer, an inner coating layer and an outer coating layer; the whole bottom plate layer is similar to a rectangle, the periphery of the bottom plate layer is slightly warped forward and is concave gradually to the center, and the middle part thereof is provided with two rows of air vents along the vertical direction; the inner coating layer is made of three-dimensional high-density, high-elasticity soft materials, wherein the elasticity of the outer layer is excellent, the elasticity of the inner layer takes the second place, and the size and the shape of the inner coating layer are same as that of the bottom plate layer; and the outer coating layer is made of mesh fabrics, wraps the inner coating layer tightly, and is attached at the front of the bottom plate layer. The double backrest of an air-permeable seat can be widely applied to the double-back seats of different occasions, such as aircraft seats, car seats, office seats and the like.

Description

The two backrests of gas permeability seat

Technical field

The utility model relates to a kind of seat component, and more particularly, it relates to a kind of two backrests of seat of gas permeability.

Background technology

Each backrest in two backrests of the backrest of traditional Chinese chair or existing two back of the body seats, mostly be greatly and paste the typing sponge on the wooden floor, with leather or cloth wooden floor is become an integral body with the typing sponge wrapping, such backrest people's back is leaned on up and can be felt soft, but shortage gas permeability, if under the environment temperature condition with higher, can feel very sultry above leaning against for a long time, extremely uncomfortable.

At the problems referred to above that traditional Chinese chair exists, the someone has made some and has improved, and has improved the gas permeability of backrest.Chinese patent 03261188.9 discloses a kind of seat structure of improvement, on the wooden floor of backrest and the sponge of finalizing the design, all offer most air-vents, although have the function of gas permeability, but owing to contact direct perforate on the typing sponge of (centre have only one deck breathe freely cloth) with human body back, human body may not feel well, although the air-vent on the typing sponge evenly distributes simultaneously, but need to guarantee certain spacing between the Kong Yukong, the gas channel that the human body back heat distributes distributes and is inhomogeneous, and permeability is unsatisfactory.

The utility model content

The purpose of this utility model is to provide a kind of gas permeability seat two backrests, at the deficiency on the prior art, has not only realized air permeability and good, more considers the comfortableness when human body takes a seat.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

The two backrests of a kind of gas permeability seat, two backrest axial symmetry are installed on the back bracket that combines, each backrest wherein all comprises backplane level, internal coated layer and outer covering layer, described backplane level is whole for being similar to rectangle, littlely on every side stick up forward, gradually to central concave, two row's air-vents are vertically offered in the position, intermediate portion, described internal coated layer is that the highly dense high-elastic soft material of two-layer 3D is made, and its ectomesoderm elasticity is splendid, and nexine elasticity is taken second place, size and shape is identical with described backplane level, described outer covering layer is made for the screen cloth material, and described internal coated layer is tightly wrapped, and is attached to the front of described backplane level.

Described backplane level is that plank, carbon fibre material or plastics are made, and air-vent is rule or irregular geometry on it.

Compared with prior art, the advantage that the two backrests of gas permeability seat of the present utility model are had is, because internal coated layer is that the highly dense high-elastic soft material of 3D is made, ventilative duct is evenly distributed on it, the gas channel that the human body back heat distributes distributes and also becomes relatively even, flow resistance reduces, adding the back makes internal coated layer that local mild compression distortion take place to the external force effect of backrest, change its internal cavity volume, quicken hot-fluid gas flow speed in it, further improved ventilative radiating condition.Because directly the highly dense high-elastic soft material elasticity of outer 3D that contacts with human body back is splendid, the surface is evenly smooth, has also increased the comfortableness when human body takes a seat simultaneously.The two backrests of this gas permeability seat can be widely used on two back of the body seats of different occasions such as aircraft seat, automotive seat and office seating.

Among the figure: highly dense high-elastic soft material 22 outer covering layer screen cloths 3 one of them backrest 4 another backrest 5 backrest bracing or strutting arrangements 6 back bracket 7 of the backplane level 1 air-vent 11 internal coated layer internal layer 3D outer 3D of highly dense high-elastic soft material 21 internal coated layers

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

Fig. 1 is the perspective exploded view of one of them backrest of the present utility model.From figure, can clearly find out, one of them backrest 4 of the two backrests of gas permeability seat of the present utility model comprises: highly dense high-elastic soft material 22 of highly dense high-elastic soft material 21 of the internal layer 3D of backplane level 1, internal coated layer and outer 3D and outer covering layer screen cloth 3 etc., this backrest 4 is whole for being similar to rectangle, wherein backplane level 1 is made for plank, carbon fibre material or plastics, littlely on every side stick up forward, gradually to central concave, two row's air-vents 11 are vertically offered in the position, intermediate portion, and air-vent 11 is rule or irregular geometry; The outer 3D of internal coated layer is highly dense, and high-elastic soft material 22 elasticity are splendid, and internal layer 3D is highly dense, and high-elastic soft material 21 takes second place, and their size and shape is identical with backplane level 1; Outer covering layer screen cloth 3 tightly wraps highly dense high-elastic soft material 21 of internal coated layer internal layer 3D and the highly dense high-elastic soft material 22 of outer 3D, is attached to the front of backplane level 1.

Fig. 2 and Fig. 3 are forward directions of the present utility model and back to the assembling schematic perspective view.As can be seen from the figure, constitute a backrest according to the assembling mode of above-mentioned building block to one of them backrest 4 of the present utility model among Fig. 1, and the global shape of another backrest 5 and this backrest 4 are axisymmetric shape.One of them backrest 4 and another backrest 5 also are to be symmetry axis with the central vertical shaft, be installed on the back bracket 7 by two backrest bracing or strutting arrangements 6, two backrest bracing or strutting arrangements 6 and the link position of one of them backrest 4 and another backrest 5 will be avoided the air-vent 11 on the backplane level 1.

The utility model provides a kind of gas permeability seat two backrests, has adopted the highly dense high-elastic soft material of 3D, has not only realized air permeability and good, more considers the comfortableness when human body takes a seat.The two backrests of this gas permeability seat can be widely used on two back of the body seats of different occasions such as aircraft seat, automotive seat and office seating.
