Description
Technical field
The utility model relates to automotive safety technical field, specifically a kind of open airbag housing.
Background technology
Seat side airbag is the inside cavity that is accommodated in vehicle seat back foaming, and is connected on seat back-rest framework side adapter plate by fastener.Seat side airbag for the protection of with reduce occupant side to the degree that is hurt in traffic accident.In the time that vehicle ECU receives the acceleration signal from sensor, by automatic decision, if meet the quick-fried condition of point, will provide ignition signal, and trigger the gas generator in air bag module, safety air bag fast aeration is deployed into vehicle interior.
The common design of side airbag module comprises dust boot or housing and the gas generator of folding airbag, outer parcel, gas generator is directly installed or is installed to by support in the cavity of back of seat side stay bearing plate and foaming, and folding airbag is wrapped in gas generator outside and is wrapped in by outer field dust boot or housing.On the dust boot of plastic material or housing, have the suture of tearing of intentional reduction, object is in the time that gas generator is inflated air bag, reduction tear suture energy rate tear initiation, make airbag launch put in place according to the direction of design.
At present, the air bag of this class design all adopts Soft Roll air bag or entirely wraps duricrust air bag.Soft Roll air bag is to adopt nonwoven fabrics to be wrapped in the outside of airbag, and nonwoven fabrics is for fixing airbag bag type and dustproof.Adopt this design, seat need to increase the guide frame of pocket type, and the effect of the guide frame of pocket type is to lead for airbag deployment.Full bag duricrust air bag is to adopt plastic casing to be wrapped in outside airbag, and plastic casing is for fixing airbag bag type, dustproof and guiding.Adopt this design, seat can not do the guide frame of pocket type, also can reach good appearance effect being assembled to A face after seat, but its mounting structure is more complicated, produces the risk point losing efficacy more, as positions such as buckle, hinge, tear lines.
If German patent is the air bag patent of DE102005033677 (A1), be entirely to wrap the seat of duricrust airbag matching with guiding bag, this design is to wrap up and fixation balloon by full bag hard shell body upper and lower and that front and back are all sealed.Upon deployment, be by the line of weakness of full bag hard shell body tear, the guiding of guiding bag is helped air bag and is immediately launched accurately to put in place in hinge upset and housing and seat.The advantage of this design is stable and reliable for performance, but more, the seat of risk point that the structure of air bag is more complicated, exploitation was lost efficacy with special air bag protective bag, assembly technology is more loaded down with trivial details, cost is high.
Therefore, in order to simplify airbag housing structure, reduce failure rate in exploitation, improve efficiency of research and development and reduce seat cost and improve the operability of assembling, need to design a kind of simple in structure, dependable performance and be easy to mate the open airbag housing of seat.

Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described further.
Embodiment 1
Referring to Fig. 1 and Fig. 2, enclosure body in this example is three open architectures 1 of front end, three openings in top and bottom, air bag module is made up of enclosure body and the airbag bag type fixation adhesive tape 12 of gas generator 4, airbag 5, three open architectures 1, the rear end of three open architectures 1 is provided with hinge 11, in three open architectures 1, be provided with airbag 5 and producer 4, with bolts between three open architectures 1 and airbag 5, bolt is that producer 4 carries.The outside of airbag 5 is provided with airbag bag type fixation adhesive tape 12.
Fig. 3 is that seat 3 assembles three side schematic views after open architecture air bag module, and air bag module is fixed in the module die cavity that the foaming 32 of seat 3 reserves.
In Fig. 4, can see between enclosure body and the adapter plate 31 of seat 3 and adopt the bolt 41 on producer 4 to be connected, bolt 41 through after airbag 5, enclosure body and adapter plate 31, is fastenedly connected with nut successively.
Referring to Fig. 5 and Fig. 6, in the time that safety air bag is worked, 4, producer is fought and is outwards discharged a large amount of high temperature and high pressure gas, is full of airbag 5.After airbag 5 inflations, expanding volume increases, strut the enclosure body of airbag bag type fixation adhesive tape 12 and three open architectures 1, the enclosure body of three open architectures 1 is stressed and flips to the outside along hinge 11, lead to the outside that is deployed in of airbag 5, the airbag 5 after inflation puts in place from the passage expansion forming between the enclosure body of three open architectures 1 opened and the foaming 32 of seat 3.
This example, in airbag 5 expansion processes, is wrapped duricrust air bag to foaming 32 ram ratios of seat 3 large entirely, can reduce by following two kinds of modes but impact:
Mode one: in the cavity that the foaming 32 of seat 3 is mated with side air bag module, on the path of launching at airbag 5, foam 32 use nonwoven fabrics or felt are strengthened, also can be by increase one deck guiding cloth in surface cover, intercept thereby form one deck between 32 cavitys in air bag module and foaming, 32 in airbag 5 expansion processes, be subject to excessive impact and break to ensure that the smooth expansion of airbag 5 puts in place also to prevent from foaming.
Mode two: airbag 5 adopts the outwards folding mode of turnover, and the path while guiding airbag 5 to launch is first to seat 3 sides, to avoid the direct impact of the front end foaming 32 to three open architectures 1.
Embodiment 2
Referring to Fig. 7 and Fig. 8, enclosure body in this example is two open architectures 2 of two openings in front top and bottom, air bag module is made up of the enclosure body of gas generator 4, airbag 5, two open architectures 2, the top and bottom of two open architectures 2 are provided with hatch frame, the rear end of two open architectures 2 is provided with hinge 21, the front end of two open architectures 2 adopts buckle 22 or adhesive tape to fix, bag type after buckle 22 or adhesive tape are folding for fixing airbag 5, the front end side of two open architectures 2 is provided with line of weakness 23.
Fig. 9 is that seat 3 assembles two side schematic views after open architecture air bag module, and air bag module is fixed in the module die cavity that the foaming 32 of seat 3 reserves.
In Figure 10, can see between enclosure body and the adapter plate 31 of seat 3 and adopt the bolt 41 on producer 4 to be connected, bolt 41 through after airbag 5, enclosure body and adapter plate 31, is fastenedly connected with nut successively.
Referring to Figure 11 and Figure 12, in the time that safety air bag is worked, 4, producer is fought and is outwards discharged a large amount of high temperature and high pressure gas, is full of airbag 5.After airbag 5 inflations, expanding volume increases, strut the enclosure body of two open architectures 2, the buckle 22 or the side line of weakness 23 that after the enclosure body of two open architectures 2 is stressed, deliberately design reduction along front end are opened, and flip to the outside along hinge 21, lead to the outside that is deployed in of airbag 5, the airbag 5 after inflation puts in place from the passage expansion forming between the enclosure body of two open architectures 2 opened and the foaming 32 of seat 3.
This example is in airbag 5 expansion processes, the impact of the foaming 32 to seat 3 is similar with full bag duricrust air bag, between the front end of airbag 5 and the foaming 32 of seat 3, have enclosure body to intercept, avoided airbag 5 after inflation to foaming 32 direct impact, can reduce to foam 32 cracked risks.
The material of the utility model middle shell body is thermoplastic elastomer (s) TPO, makes by injection moulding or expressing technique, lightweight, volume is little, cost is low.
