Abstract

The utility model discloses structures of a back cushion and a headrest, both of which are formed by combining a surface substrate and a back front substrate made of flexible and elastic materials; the combined surface of the two substrates is a depressed space; and a plurality of solid convex bodies are arranged on the upper half section of the depressed space; and a flow channel and through breather holes are arranged between two solid convex bodies; while the lower half section of the depressed space is hollow and is the inside-concave convex body of an inside-concave air chamber; while one side of the inside-concave air chamber is provided with a shallow cutting slot; when the two substrates are combined together to form the back cushion for a user to lie on, the contact pressure of the upper half of the body can be born by different support forces generated inside the two substrates; moreover, reactive thrust generated in the air chamber is used for protecting a back skeleton and different deformation forces of the air chamber are used for forming a human engineering shape to prevent muscles from generating aching pains due to excessive deformation; then the design of the air chamber and the breather holes can timely radiate the heat of the human body through the flow channel and the breather holes surrounding the convex body. The structures of the back cushion and the headrest have the effects of simultaneously realizing pressure dispersing, ventilation, uniform support and protection.

Description

The structure of a kind of back pad and headrest

Technical field

The utility model relates to the structure of a kind of back pad and headrest.

Background technology

Press, the design of general relevant back pad its outer be emphasize with state-of-the-art special substance made,, comfortable function performance ventilative to have.But examine the back pad content that is sold on the market at present,, do the variation in moulding of style afterwards again in appearance still based on the material of foam of different soft and hard degree and so on; Yet the foam of this use is because its inner density is to be identical relation, therefore toward back pad by after touching a period of time, just can feel more by more tired, reason promptly be human body back loosen toward back pad touch by the time, its gravity above the waist just toward back pad move, especially the lower back position bear burdens bigger, this moment as preceding the above the back pad structural design to consider not be under the so thorough situation so that just take place not only not allow the user produce and eliminate tired, as to loosen health " more by more tiring out " phenomenon.So not only can cause the injury of its muscle of back accumulating over a long period, even also can cause original entopic skeleton to produce all of deformation and other related property gradually and ache and pathology.

Therefore, the applicant must propose the utility model.

Summary of the invention

The purpose of this utility model is to provide the structure of a kind of back pad and headrest, and the defective that it can overcome existing structure makes the user avoid occurring the phenomenon of " more by more tiring out ".

For achieving the above object, the utility model discloses the structure of a kind of back pad and headrest, is to make front base material and back side base material to constitute back pad and headrest pasting in conjunction with the back mutually with two soft elastic materials; Faying face at front base material and back side base material is respectively equipped with dented space, it is characterized in that:

On front base material and base material upper semisection position, the back side, be shaped on a plurality of solid convex bodys, and between two solid convex bodys, be provided with circulation road and be the air-vent of penetration state; And the base material lower semisection is made as the indent convex body that hollows out shape and be the indent air chamber overleaf, and be provided with shallow profile groove in indent air chamber one side, and then be provided with circulation road between two indent convex bodys, the front of the front base material of whole back pad and headrest is designed to the concave arc moulding of streamline.

Pass through said structure; the structure of back pad of the present utility model and headrest utilizes a plurality of solid convex body in the base material of two sides to produce different support force designs down with the indent convex body; think and bear pressing of the health upper part of the body; and then can avoid muscle to produce the injury of aching because of excessive deformation by the ergonomics external form that the recoil strength that air chamber produced protects the different deformation power of back shell and air chamber to form; and the design of air chamber and air-vent; the circulation road and the air-vent that then in time human body hot gas are followed the convex body periphery dissipate to row, have to reach dispersive pressure simultaneously; ventilative; the even effect that supports and protect.

When the two sides base material is being when being integrated as one, the solid convex body of front base material is the indent air chamber top periphery of the solid convex body of base material and indent convex body overleaf that bridges just, think that producing elastic reaction absorbs and cushion the weight person who is born this moment simultaneously, the shallow profile groove that indent air chamber one side is provided with has the effect of releasing loose power and hot gas;

Be the circulation road design that communicates between a plurality of convex bodys that in the dented space of two sides base material, are provided with, and the air-vent that is provided with penetration state between each convex body of base material place, two sides in the circulation road, the effect that the hot gas that the energy reinforcement produces human body sheds to row, with the ventilative effect of tool, on the headrest front, be made as the concave arc moulding of streamline, more docile to cooperate the human body head curve.

The specific embodiment

At first, please cooperate shown in the detailed description of consulting Fig. 1, Fig. 2, Fig. 3: the structure of a kind of back pad of the present utility model and headrest, be the front base material 1 made with two soft elastic materials and back side base material 2 think paste mutually in conjunction with after formation back pad and headrest; Faying face at the two sides base material is respectively equipped with dented space, and is shaped on a plurality of solid convex bodys 11,21 on front base material 1 and back side base material 2 upper semisection positions, and then is provided with circulation road 12,22 and is the air-vent 13 of penetration state between two solid convex bodys 11,21; Base material 2 lower semisections then are made as the indent convex body 23 that hollows out shape and be indent air chamber 24 overleaf, and are provided with shallow profile groove 25 in indent air chamber 24 1 sides, and then are provided with circulation road 26 between two indent convex bodys 23; Solid again convex body 11 and indent convex body 21,23 can be changed to the relative moulding of difformity and size, and the front base material 1 of whole back pad and headrest positive and can be designed to the concave arc moulding of streamline thought to cooperate the human body back of the body, nose curve and form docile touching by use.

When the user lies when pressing doing, because the two sides base material is being when being integrated as one, the solid convex body 11 of front base material 1 is the indent air chamber 24 top peripheries (as Fig. 4, Fig. 5, Fig. 6, Fig. 7) of base material 2 solid convex bodys 21 and indent convex body 24 overleaf that bridge just, thinks that producing elastic reaction absorbs simultaneously and cushion the weight person (as Fig. 8, Fig. 9) who is born at this moment; Thus; can utilize a plurality of solid convex body 11 and indent convex body 21 in this two sides base material; 23 produce the design of different support forces down; think and bear pressing of the health upper part of the body; and protect the ergonomics external form of the different deformation power formation of back shell and indent air chamber 24 by the recoil strength that indent air chamber 24 is produced; think and avoid muscle to produce the injury of aching because of excessive deformation; and the shallow profile groove 25 of indent air chamber 24 and the design of air-vent 13; then in time human body hot gas is followed each convex body 11; 21; the circulation road 12 of 23 peripheries; 22; 26 and air-vent 13 dissipate to row, have and reach dispersive pressure simultaneously; ventilative; the even effect that supports and protect.
