Description

Most two independent air chamber air bags

[technical field]

The utility model relates to the two independent air chamber air bags of a kind of majority, effectively reaches most two unidirectional aeration persons of independent air chamber.

[background technology]

Tradition air cushion or airbag all are used for protecting valuable electronic product; prevent that article from causing collision, shatter damage; air cushion or airbag are only with the big inflation area of a succession of ventilation of individual layer face as only; as long as causing sticker breaks and promptly loses the whole air cushion of effect and can't use; if then cause the gas problem of losing heart easily in two-way turnover mode inflatable and that lose heart; therefore; how when causing sticker and break, still can use and have the effect of anticollision, be the place of the technical difficulties of inventor institute desire solution.

[summary of the invention]

The main purpose of the utility model is to provide a kind of majority two independent air chamber air bags, it is characterized in that; One airbag, in have most two independent air chambers, be connected with L type air flue with the second air chamber front end air flue in this first air chamber; One L type air flue, an end is provided with a main gas port; The a pair of independent air chamber comprises a upper strata air chamber and lower floor's air chamber; One first admission port is positioned at the upper left side of upper strata air chamber one side; And one second admission port, be positioned at the lower right of lower floor's air chamber one side; One diaphragm is positioned in the middle of two independent air chambers; Film lobe on one, be to place the diaphragm top and extend to be connected to rear inside wall edge, there is the first admission port air inlet on two independent air chamber front ends upper left side, and to the inflation of upper strata air chamber, last film lobe pressurized is oppositely interior closely pastes effective prevention air inlet and the effect of losing heart mutually with diaphragm by last film lobe hole, left side; Film lobe once, be to place the diaphragm below and extend to be connected to rear inside wall edge, there is the second admission port air inlet simultaneously two independent air chamber front end lower rights, to lower floor's air chamber inflation, film lobe pressurized is oppositely interior on another closely pastes effective prevention air inlet and the effect of losing heart mutually with diaphragm by last film lobe hole, left side; One hole is positioned at film lobe left-hand portion on the diaphragm top; And a hole, be positioned at film lobe left-hand portion under the diaphragm below, all be the effect of unidirectional air inlet inlet.

The advantage of the utility model is: 1. each two independent air chamber is all separate single to air inlet and singlely independently finish in the airbag, and its gas only import but no export forms the independent separately air chamber that does not communicate.2. having L type air flue is blown into gas in each two independent air chamber.3. when upper strata air chamber and any fault of lower floor's air chamber, airbag still can continue to use unaffected.4. each two independent air chamber one side is extended with a convergence part and can tears excision arbitrarily not partly, further reaches the integraty of airbag use.5. airbag is connected the feasible expansion use of at least one continuous area size of extension with another airbag.

[specific embodiment]

See also Figure 1 and Figure 2, have most two independent air chambers 3 in the airbag 1 among the figure, gas enters via airbag 1 one end master gas ports 2 and forms a L type air flue 20, be extended with a convergence part 22 in L type air flue 20 1 sides, on convergence part 22, there is open-work 220 to be convenient to convergence part 22 is torn, first air chamber 10 on airbag 1 surface laterally links to each other with second air chamber 11 and second air chamber, 11 front ends have an interval air flue 100 to lead to mutually with L type air flue 20, via L type air flue 20 gas is blown in each two independent air chamber 3, this pair independent air chamber 3 is divided into individual independent stratum up and down, there is one first admission port 40 on air chamber 4 one side upper left sides in upper strata, and these lower floor's air chamber 5 front end lower rights have second admission port 50 to be declivity location on two independent air chambers, see also shown in Figure 3, there is a diaphragm 30 to form two independent air chambers up and down in the middle of wherein in this pair independent air chamber 3, diaphragm about in the of 30 on the both sides film lobe 31 all be connected to rear inside wall edge 300 with following film lobe 32, film lobe 31 left-hand portion have a hole 310 to be unidirectional air inlet inlet on diaphragm 30 tops, and film lobe 32 left-hand portion are provided with a hole 320 unidirectional air inlet inlets under these diaphragm 30 belows, when being blown into L type air flue 20, gas is full of each two independent air chamber 3 simultaneously, gas has the second admission port 50 pressurized inflation simultaneously by first admission port 40 and lower floor's air chamber 5 front end lower rights on upper strata air chamber 4 upper left sides simultaneously, gas is via first admission port, 40 air inlets on two independent air chambers 3 front end upper left sides, by hole, last film lobe 31 left side 310 upper strata air chamber 4 is inflated, last film lobe 31 pressurizeds are oppositely interior closely pastes effective prevention air inlet and the effect of losing heart mutually with diaphragm 30, there are 50 air inlets of second admission port simultaneously two independent air chamber 3 front end lower rights, by following hole, film lobe 32 left side 320 and to 5 inflations of lower floor's air chamber, film lobe 32 pressurizeds are closely pasted effective prevention air inlet mutually and are lost heart with diaphragm 30 in oppositely and act on another on.

See also shown in Figure 4ly, first air chamber 10 on airbag 1 surface among the figure is to be linked to each other by convergence part 21 with second air chamber 11, has open-work 210 to be convenient to excision is torn in convergence part 21 on convergence part 21, further reaches the integraty of airbag 1 use.

See also shown in Figure 5ly, airbag 1 side among the figure has a convergence part 22 to be connected with another airbag 6 to extend at least one continuous area size, this airbag 1 extendible prolongation is used.
