Description
Technical field
The present invention relates to vehicle passive safety device technique field, specifically a kind of overhead type airbag apparatus.
Background technology
In vehicle frontal collision vehicle accident, air bag for copilot protection copilot occupant escape injury.Copilot
Air bag protects occupant by the optimization of different shapes, volume, internal pressure and generator.Tradition air bag for copilot
The counteracting force relying on instrument board obtains and supports, and then provides protection for copilot occupant.
In head-on crash vehicle accident, tradition air bag for copilot utilizes the support force of copilot side instrument board to retrain
Occupant.So tradition air bag for copilot design depends on the surface profile of instrument board.
But, some vehicles for retention outside copilot's leg room and eliminate the setting of instrument board, for
Such vehicle, tradition air bag for copilot just cannot employ.
Accordingly, it would be desirable to design one can retrain occupant under conditions of not having fascia supports effectively, there is oneself
The overhead type airbag apparatus of support function.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of can not have the condition of fascia supports
Under effectively retrain occupant, there is the overhead type airbag apparatus of self-sustained function.
In order to achieve the above object, one overhead type airbag apparatus of the present invention, including gas generator and overhead type air bag
Module, it is characterised in that: gas generator and overhead type air bag module are arranged in roof of the vehicle, and the airbag after folding is placed in top
Putting in formula air bag module, the inside of airbag is provided with interior drawstring, and the outside of airbag main leaf is provided with two fixing points, the two ends of outer drawstring
Being separately fixed on two fixing points, the length of outer drawstring is less than the spacing of two fixing points, after air bag inflator, two fixing points
Airbag main leaf be crimp shape.
Described outer drawstring is positioned at the bottom of airbag, and during air bag inflator, crimp shape defines vehicle body advance side
To tension force, tension force counteract windshield formed asymmetric support force and occupant's impulsive force.
Described outer drawstring is positioned on the airbag main leaf of occupant, outer drawstring decrease airbag launch during upper and lower
Oscillatory forces, decreases the contact area of airbag and windshield, reduces the asymmetric support force that windshield is formed, reduces
The moment that airbag rotates to vehicle body direction of advance, during air bag inflator, crimp shape defines and is parallel to windshield side
To tension force, the impulsive force that tension force counteracts occupant's head and trunk travels forward and rotates.
Described outer drawstring is positioned on the airbag main leaf of windshield, during air bag inflator, along with airbag pair
The energy-absorbing buffering of occupant's impulsive force, crimp shape gradually compressed, and the airbag main leaf at crimp shape gradually connects with windshield
Touching, crimp shape defines the tension force being parallel to windshield direction, and tension force counteracts the decrement that crimp shape compression produces
Power.
The length of described outer drawstring is adjusted according to angle and the occupant space size of windshield.
The present invention compared with the existing technology, under the effect by inside and outside drawstring of the overhead type airbag apparatus, copilot side air bag
Expansion shape can be continual and steady, it is achieved self-sustained function, it is not necessary to obtains at instrument board and supports, and breaks away from instrument board and makes
The impact of type design.The present invention sets up outer drawstring outside airbag, makes airbag have not Tongfang by the outer drawstring of diverse location
To tension force, produce moment that opposing airbag rotates or control airbag and windshield contact position and area, it is the most right to reduce
Claim support force.

Detailed description of the invention
In conjunction with accompanying drawing, the present invention is described further.
When vehicle collides, gas generator 4 inflate to polyhedron airbag 8, make airbag 8 fill up copilot and wind
Space between gear glass 2, protects occupant.Airbag shape profile design is true according to the upper trunk requirement of protection occupant
Fixed.The front end of airbag 8 contacts with windshield 2, and the head of rear end and occupant 6, neck, chest contact.Air bag absorbs occupant's impact energy
Amount length and occupant's contact position are by interior drawstring 9 length adjustment.
Owing to air bag moves to ceiling 5 from instrument board, instrument board is cancelled or changes into expand driver leg space
Copilot side instrument 1, airbag 8 lower end by contacting the support obtained with instrument board and cannot be fixed.And the song of windshield 2
Face moulding forms it into left-right asymmetry support force.When asymmetric support force and occupant's impulsive force of windshield 2 are made respectively
When the front and rear portions of airbag 8, the moment making airbag 8 around vehicle body direction of advance can be formed, cause airbag 8 to rotate deviation protection
Position, thus cause headform whiplass in experimentation.In order to solve the problems referred to above, the present invention installs outside airbag 8
Outer drawstring 10.
Seeing Fig. 1, the present invention is a kind of overhead type airbag apparatus, including gas generator and overhead type air bag module.Gas
Body generator 4 and overhead type air bag module 3 are arranged in roof of the vehicle 5, and the airbag 8 after folding is placed in overhead type air bag module 3
In, the inside of airbag 8 is provided with interior drawstring 9.Seeing Fig. 5, airbag is sewed by airbag main leaf 11 and airbag lateral plate 12 and forms.Airbag master
The outside of sheet 11 is provided with two fixing points, and the two ends of outer drawstring 10 are separately fixed on two fixing points, the length of outer drawstring 10
Less than the spacing of two fixing points, after airbag 8 inflation, the airbag main leaf 11 of two fixing points is in crimp shape.
Seeing Fig. 2, outer drawstring 10 is positioned at the bottom of airbag 8, and in airbag 8 gas replenishment process, crimp shape is inside airbag
Outside pressure, crimp shape also form the tension force F of vehicle body direction of advance, and tension force F counteracts the asymmetric of windshield 2 formation
Support force and occupant's impulsive force, reduce consequent turning moment, it is ensured that in automobile collision procedure, and airbag 8 is the most lateral
With the motion in vertical direction.The length of outer drawstring 10 is adjusted according to angle and the occupant space size of windshield 2.
Seeing Fig. 3, outer drawstring 10 is positioned on the airbag main leaf 11 of occupant 6, and outer drawstring 10 decreases airbag 8 to launch
Swinging up and down power in journey, decrease the contact area of airbag 8 and windshield 2, reduce that windshield 2 formed is asymmetric
Support force, reduces the moment that airbag 8 rotates to vehicle body direction of advance, and in airbag 8 gas replenishment process, crimp shape is in airbag
Outside portion's pressure, crimp shape also form the tension force F being parallel to windshield direction, and tension force F counteracts occupant 6 head and body
The dry impulsive force travelling forward and rotating, reduces occupant injury.Simultaneously as decrease the impulsive force of occupant, reduce further
Making the moment that airbag rotates, it is ensured that in automobile collision procedure, airbag 8 does not has the motion laterally and in vertical direction, keeps gas
Bag 8 stablizing in collision process.
Seeing Fig. 4, outer drawstring 10 is positioned on the airbag main leaf 11 of windshield 2, in airbag 8 gas replenishment process, with
The airbag 8 energy-absorbing buffering to occupant's impulsive force, crimp shape is gradually compressed, the airbag main leaf 11 at crimp shape gradually with
Windshield 2 contacts, and crimp shape defines the tension force F being parallel to windshield direction, and tension force F counteracts crimp shape compression
The compression produced is measured one's own ability.In this process, the airbag area contacted with windshield 2 is gradually increased, it is achieved to asymmetric
The control of support force, and then reduce the moment making airbag 8 rotate, keep airbag 8 stablizing in automobile collision procedure.
