Fig. 4 is the schematic diagram of the air bag of one embodiment according to the present utility model.Fig. 5 is according to the utility model
One embodiment air bag schematic diagram in a state of use.Referring to Fig. 4 and Fig. 5 descriptions according to the utility model
Air bag 100.
In fig. 4 it is shown that the air bag 100 in unfolded state.Air bag 100 includes first to communicate with each other
Part 101 and Part II 102.
Figure 5 illustrates the schematic diagram of air bag 100 in a state of use.As shown in figure 5, overhead type air bag group
The right part 1010 of the Part I 101 of part is fixed on the top of vehicle, and the windshield and instrument board of vehicle are located at first
Divide 101 left side, occupant is located in the space that the right side of Part II 102 and the downside of Part I 101 are formed.
In addition, returning to Fig. 4, Part I 101 can be configured in the state of inflation along the gear of vehicle
Wind glass extends downwardly and the left part of Part I 101 1011 can be located between the instrument board and windshield of vehicle,
Part II 102 can be configured in the state of inflation from the left part 1011 of Part I 101 nearby towards multiplying
Member's extension.
As shown in figure 4, overhead type air-bag module according to the present utility model further includes air flow guide member 200, should
Air flow guide member 200 can be configured to elongated cylindrical component.Air flow guide member 200 can be arranged on air bag
The inner side of 100 Part I 101 and there is air inlet 201 and gas outlet 202, air inlet 201 can be arranged on air-flow
One end of guiding elements 200 and it is connected with gas generator, gas outlet 202 can be configured to guide in air-flow
Another end opposite with air inlet 201 of component 200.When being inflated to air bag 100, the flowing road of air-flow
Footpath is：Gas enters air flow guide member 200 by the air inlet 201 being connected with gas generator, next, gas passes through gas
The gas outlet 202 for flowing guiding elements 200 flows into Part I 101 and Part II 102 so that Part I 101 and second
102 are divided little by little to be unfolded.Part II 102 is in the deployed state to the offer protection such as the head of occupant, neck and thoracic cavity.
Therefore, the air flow guide member 200 of overhead type air-bag module according to the present utility model, which has, sends out gas
The effect that the gas that raw device produces guides.Specifically, when vehicle collides or is impacted, gas generator explosion
Caused gas flows into air flow guide member 200 first, and air flow guide member 200 in the deployed state will be along
Windshield extends downwardly, and the air flow guide member 200 under unfolded state has certain rigidity and hardness, therefore air-flow
Guiding elements 200 can drive Part I 101 to be opened up with air flow guide member 200 when along windshield drops down
Open, thus guide Part I 101 similarly along windshield drops down.Further, in Part I 101 along gear
After wind glass is fully deployed downwards, the left part 1011 of Part I 101 will be between windshield and instrument board.Cause
This, under the unfolded state of air bag 100, the left part between windshield and instrument board of Part I 101
1011 can have an effect with the right part 1010 being fixed in the top of vehicle as two fulcrums, thus stably at support
In unfolded state Part I 101 so that it is guaranteed that Part I 101 reliably works.
Therefore, overhead type air-bag module according to the present utility model is able to ensure that air bag edge in the deployed state
Windshield to extend downwardly.Therefore, the overhead type air-bag module of the utility model has higher reliability and safety
Property.
In the embodiment of overhead type air-bag module according to the present utility model as shown in Figure 4, air-flow guiding structure
Part 200 and air bag 100 can be configured to place's connection only near the air inlet 201 of air flow guide member 200 and
Remainder is kept completely separate.
The design that above-described embodiment according to the present utility model, air bag 100 and air flow guide member 200 are separated from each other
It is able to ensure that air bag 100 will not be subject to the relatively thump of gas while being subject to effectively to guide, thereby it is ensured that air bag
100 have longer service life.
Other preferred embodiment according to the present utility model, as shown in fig. 6, air flow guide member 200 ' and air bag
100 can also be arranged to common surface, i.e. the upper surface of air flow guide member 200 ' can be used as air bag at the same time
100 upper surface, the upper surface extend to the outlet of air flow guide member 200 ' from the air inlet of air flow guide member 200 '
Mouthful.Those skilled in the art according to the actual needs can also differently design above-mentioned common surface, for example, this is shared
Surface can only extend a part since the air inlet of air flow guide member, afterwards air bag and air flow guide member point
From.
Above preferred embodiment according to the present utility model, air bag and air flow guide member, which are arranged to have, to be shared
Surface can save material, reduce cost.
Preferred embodiment according to the present utility model, can be set to point to the glass that keeps out the wind by the gas outlet of gas generator
Glass so that the air inlet of air flow guide member is also directed to windshield.Thereby it is ensured that air flow guide member in the deployed state will
Extended downwardly along windshield, so that it is guaranteed that air bag is extended downwardly along windshield in the deployed state so that this
The overhead type air-bag module of utility model has higher reliability and security.
Preferred embodiment according to the present utility model, the length of air flow guide member can be configured to equal to less than first
Partial length, i.e. size of the air flow guide member on the direction extended along windshield exists equal to less than Part I
Size along on the direction of windshield extension.Thereby it is ensured that air flow guide member guiding air bag is in the deployed state
Extended downwardly along windshield so that the overhead type air-bag module of the utility model has higher reliability and safety
Property.
It will be appreciated by those skilled in the art that the air bag of overhead type air-bag module according to the present utility model
Part II be not limited to from state in inflation when extend towards occupant near the left part of Part I.Part II
It can also extend from the other parts of Part I towards occupant, such as extend from the center section of Part II towards occupant,
As long as Part II can effectively protect the offers such as the head of occupant, neck, thoracic cavity.
It will be appreciated by those skilled in the art that the air inlet of air flow guide member is not limited to be directed toward windshield.For example,
In the case of not limiting the air inlet of air flow guide member, as long as being designed to the shape and structure of air flow guide member, make
It can guiding elements guiding air bag extended downwardly in the deployed state along windshield.
As it was previously stated, although the exemplary embodiment of the utility model is illustrated by reference to attached drawing in explanation,
But the utility model is not limited to above-mentioned embodiment, the scope of protection of the utility model should by claims and its
Equivalents limit.
