Beneficial effect of the present invention is, safety air bag of the present invention, and when automobile bumps, gas generator can make the first gasbag launch fully rapidly, and when OOP occupant contacts with safety air bag, the first gasbag can provide actv. protection to OOP occupant.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification sheets, and for above and other purpose of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.
The accompanying drawing explanation
Fig. 1 is the structural representation of the safety air bag of one embodiment of the invention.
concrete the present embodiment
Reach for further setting forth the present invention technological means and the effect that predetermined goal of the invention is taked, below in conjunction with accompanying drawing and preferred embodiment, to concrete the present embodiment of the present invention, structure, feature and effect thereof, be described in detail as follows.
Fig. 1 is the structural representation of the safety air bag of one embodiment of the invention.Please refer to Fig. 1, safety air bag of the present invention comprises the first gasbag 1, the second gasbag 2, gas generator 3 and air bag erecting frame 4.Wherein, the volume of the first gasbag 1 (while referring to aerification, lower with) is less than the volume of the second gasbag 2, and the volume ratio of the volume of the first gasbag 1 and the second gasbag 2 is as be between 1:3～1:3.5.The first gasbag 1 is contained in the second gasbag 2.Gas generator 3 is communicated with the inflation end of the first gasbag 1, and gas generator 3 is positioned at the outside of the second gasbag 2.The second gasbag 2 is fixed on air bag erecting frame 4 hermetically, and the first gasbag 1 is fixed on air bag erecting frame 4 or the second gasbag 2 hermetically.Gas generator 3 is fixed on air bag erecting frame 4.Air bag erecting frame 4 is for being installed on safety air bag in automobile.
In the present embodiment, the first gasbag 1 is provided with a plurality of first row pores 11, so that the first gasbag 1 is communicated with the second gasbag 2.For the ease of understanding, the state ejected with safety air bag after auto against describes, and after safety air bag ejects, the face over against the driver and passenger on the first gasbag 1 is upper surface, the face relative with upper surface is lower surface, and the face that connects upper surface and lower surface is periphery.A plurality of first row pores 11 are arranged at lower surface or periphery and the not close steering wheel rim of the first gasbag 1.In other words, after auto against, safety air bag ejects and is against the driver and passenger above, and first row pore 11 is arranged at the position away from driver and passenger and steering wheel rim of the first gasbag 1.A plurality of first row pores 11 are arranged at lower surface or the periphery of the first gasbag 1, after can avoiding the driver and passenger and safety air bag contacting, a plurality of first row pores 11 are blocked, and cause a plurality of first row pores 11 of the first gasbag 1 can not be to the second gasbag 2 exhausts.In the illustrated embodiment, a plurality of first row pores 11 are arranged on the periphery of the first gasbag 1, and arrange around the circumferential space of the first gasbag 1.
In the present embodiment, the second gasbag 2 is provided with second row pore 21.The quantity of second row pore 21 is for example one or two.For the ease of understanding, the state ejected with safety air bag after auto against describes, and after safety air bag ejects, the face over against the driver and passenger on the second gasbag 2 is upper surface, the face relative with upper surface is lower surface, and the face that connects upper surface and lower surface is periphery.Second row pore 21 is opened in lower surface or periphery and the not close steering wheel rim of the second gasbag 2.In other words, after auto against, safety air bag ejects and is against the driver and passenger above, and second row pore 21 is arranged at the position away from driver and passenger and steering wheel rim of the second gasbag 2.Second row pore 21 is arranged at lower surface or the periphery of the second gasbag 2, after can avoiding the driver and passenger and safety air bag contacting, second row pore 21 is blocked, and causes outwards exhaust of second row pore 21.In the illustrated embodiment, second row pore 21 is arranged on the periphery of the second gasbag 2.The aperture of first row pore 11 is greater than the aperture of second row pore 21, and preferably, in the present embodiment, the aperture ratio of second row pore 21 and first row pore 11 is for example between 1:1.5～1:2.
In the present embodiment, be provided with gunpowder in gas generator 3.
In the present embodiment, air bag erecting frame 4 is for being installed on safety air bag in automobile.
When the driver and passenger meets with a street accident by bus, safety air bag can be received the ignition order transmitted from electronic control unit (electronic control unit, ECU), gas generator 3 igniting, gunpowder explosion in gas generator 3, and produce gas rapidly to the first gasbag 1 inflation.The volume of the first gasbag 1 is little, can very fast aerification.After the first gasbag 1 aerification, the first gasbag 1 is by 11 pairs of the second gasbag 2 inflations of a plurality of first row pores.Safety air bag of the present invention is for normal occupant; when normal occupant contacts with safety airbag; the second gasbag 2 fully launches after first row pore 11 inflations on the first gasbag 1; normal occupant is with after the second gasbag 2 contacts; the second row pore 21 that compresses the second gasbag 2 and be arranged on the second gasbag 2 starts exhaust, can carry out the actv. protection to normal occupant.Be understandable that; the aperture of the aperture ratio second row pore 21 of first row pore 11 is large; in the time of can avoiding normal occupant to contact with the second gasbag 2; gas in the second gasbag 2 is excessively discharged; make the elastic effect variation of the second gasbag 2, can not play to normal occupant the effect of effective protection.Safety air bag of the present invention is for OOP occupant; when OOP occupant contacts with safety air bag; the second gasbag 2 does not launch fully; OOP occupant is with after the second gasbag 2 contacts; compress the second gasbag 2 and contact with the first gasbag 1; and aerification the expansion fully of the first gasbag 1, therefore the first gasbag 1 can provide effective protection to OOP occupant.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
