Abstract

A superposed double air bag back cushion belongs to human living articles. The back cushion is made by two big plastic films and one plastic film which are thermally bonded, and is characterized in that the back cushion is formed by two air bags with different sizes, which are tightly attached to each other and not ventilated with each other, and the section plane are in two shapes of trapezoid and horn viewing laterally. The back cushion has the advantages that the upper part of the big air bag is added with one small air bag, the air bags are inflated separately, and the effect of high-low soft-hardness at different positions of the same back cushion is generated. The small air bag directly contacting the skin of a human body is inflated less to be soft and comfort, and the use value of products is greatly improved under the condition of less increase of material cost.

Description

Two air bag back cushions that size is folded mutually

Technical field:

The utility model is a kind of two air bags of size to be incorporated into the folded mutually two air bag back cushions of size of one, genus mankind life article.

Background technology:

The air cushion of prior art all is with air-locked PVC flocked film, the monomer air bag back cushion that forms through hot press with high frequency hot pressing, the height of back cushion removes 2 by the distance between back cushion width or the two hot pressing lines and takes advantage of 3.14 and calculate, and its soft durometer is decided by the inflation saturation degree of back cushion.Nearer as the hot pressing line between back cushion, the height of back cushion is just low; Otherwise back cushion is just high; The inflation saturation degree of same back cushion is higher, and back cushion is just hard, otherwise back cushion is just soft.That is to say, because whole back cushion is a gasbag, the not variation of its height soft or hard at each position.But people still wish to have a kind of air cushion in the different height soft or hard effect of different parts generation, in actual use to satisfy people's different needs.

Summary of the invention:

For solving the deficiencies in the prior art, the purpose of this utility model is exactly that a kind of folded mutually air cushion of size in the different height soft or hard effect of different parts generation will be provided, to satisfy people's different needs.The object of the present invention is achieved like this: the utility model is made into by two big one three little plastic sheeting heat seals and it is characterized by small one and large one, two gasbags are close to the air cushion of not exchanging information again together, on air vesicle, echo a ballonet, big ballonet respectively has charge valve, can be separate, by the saturation degree of control inflation, regulate different height soft durometer.Normally the air vesicle sufficient gas makes it harder, as the moulding and the support of air cushion; The ballonet inflation makes it softer more after a little while, and when being close to skin, soft feel is comfortable.Two of its feature is that side-looking is that a ringlet is pasting the trapezoidal of a great circle when the center of ballonet at air vesicle; When the inner ring position of ballonet at air vesicle, side-looking is partial dihedral that there is a ringlet inboard of great circle.As the U-shaped inflatable packer, the ballonet of its inner ring is directly to contact human skin, so softer ballonet can allow the people feel more comfortable.

Can know from the foregoing invention content, the utility model has the advantages that: only increased a ballonet on the top of air vesicle, separate inflation just makes the different parts on same back cushion produce different height soft or hard effects.Particularly directly contact the interior few inflation of ballonet of human skin, make it soft comfortable, under the situation that seldom increases material cost, obviously improved the use value of product.

Description of drawings:

The ballonet that Fig. 1 provides for the utility model is in the front schematic view at center.

The ballonet that Fig. 2 provides for the utility model is at the side at center cut-away view.

The ballonet that Fig. 3 provides for the utility model is in the front schematic view of inner ring.

The ballonet that Fig. 4 provides for the utility model is at the side of inner ring cut-away view.

Specific embodiments:

Referring to accompanying drawing 1-4, air vesicle 1, ballonet 2, square inflatable packer 3, ringlet 4, great circle 5, U-shaped inflatable packer 6, ballonet 7, air vesicle 8, great circle 9, ringlet 10.

Referring to accompanying drawing 1-2, the utility model is made into an air vesicle 1 and a ballonet 2 by two big one three little plastic sheeting heat seals, two air bags are close to the square inflatable packer 3 of not exchanging information again together, ballonet 2 is attached to the center on the air vesicle 1, and side-looking is that a ringlet 4 is pasting the trapezoidal of a great circle 5.Air vesicle 1 and ballonet 2 separate inflations respectively with different inflation saturation degrees, are regulated two height soft durometer that air bag is different.During use, normally with the gas abundance of air vesicle 1, making air vesicle 1 moulding, solid the gas of ballonet 2 is inadequate as supporting, and makes it soft, when being close to the skin of human body in the hope of comfortable.This bar, the different parts on same air cushion has reached the effect of different soft and hard.

Referring to accompanying drawing 3-4, this is a kind of U-shaped inflatable packer 6 that is enclosed within on the human body neck neck, because the skin of neck neck only contacts the inner ring of back cushion 6, so ballonet 8 is the inner ring positions at air vesicle 7, its side-looking is that the inboard of great circle 9 has a ringlet 10 to be partial dihedral.Air vesicle 7 and ballonet 8 also are independent separately inflations, in the hope of the softness of ballonet 8.

Above-mentioned most preferred embodiment of the present utility model is described, in not exceeding invention scope of the present utility model, still can make amendment to content of the present utility model, as the profile of back cushion being changed into circle, waist shape, heart, C shape, or change the air filler of ballonet bag into cool glue cold water, just become a cool pad of combined type that nice and cool effect is arranged etc., still in invention scope of the present utility model.

Claims

1, the folded mutually two air bag back cushions of a kind of size are made by two big one three little plastic sheeting heat seals, and it is characterized in that: be close to together by two gasbags that vary in size of not exchanging information, the section side-looking has two kinds of trapezoidal and partial dihedrals.

2, according to claim 1 pair of air bag back cushion is characterized in that: when the section side-looking was trapezoidal back cushion, ballonet (1) was folded mutually in the center of air vesicle (2), and side-looking is the trapezium structure that a ringlet (4) is pasting a great circle (5).

3, according to claim 1 pair of air bag back cushion is characterized in that: the section side-looking is when leaning on the back cushion of dihedral, and ballonet (7) is folded mutually in the inner ring position of air vesicle (8), and side-looking is partial angular structure that there is a ringlet (10) inboard of great circle (9).
