Description
Technical field
The present invention relates to vehicle passive safety engineering device technique field, specifically a kind of overhead type airbag apparatus.
Background technique
In vehicle frontal collision traffic accident, air bag for copilot protection copilot occupant escapes injury.Copilot
Air bag protects occupant by the optimization of different shapes, volume, internal pressure and generator.Traditional air bag for copilot
It is supported by the reaction force of instrument board, and then provides protection for copilot occupant.
In head-on crash traffic accident, traditional air bag for copilot utilizes the support force constraint of copilot side instrument board
Occupant.So traditional 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, traditional air bag for copilot are not just available.
Therefore, it is necessary to design one kind can effectively constrain occupant under conditions of no fascia supports, there is self
The overhead type airbag apparatus of support function.
Summary of the invention
It can be in the condition of not fascia supports the purpose of the present invention is having overcome the deficiencies of the prior art and provide one kind
Under effectively constrain occupant, with self-sustained function overhead type airbag apparatus.
In order to achieve the above object, a kind of 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 mounted in roof of the vehicle, and folded airbag is placed in top
It sets in formula air bag module, the inside of airbag is equipped with interior drawstring, and the outside of airbag main leaf is equipped with two fixing points, the both ends of outer drawstring
It being separately fixed in 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 in crimp shape.
The outer drawstring is located at the bottom of airbag, and during air bag inflator, crimp shape forms vehicle body advance side
To tension, tension counteract windshield formation asymmetric support force and occupant's impact force.
The outer drawstring is located on the airbag main leaf towards occupant, and outer drawstring reduces upper and lower during airbag is unfolded
Oscillatory forces reduce the contact area of airbag and windshield, reduce the asymmetric support force of windshield formation, reduce
The torque that airbag is rotated to vehicle body direction of advance, during air bag inflator, crimp shape, which forms, is parallel to windshield side
To tension, the impact force that tension counteracts occupant's head and trunk travels forward and rotates.
The outer drawstring is located on the airbag main leaf towards windshield, during air bag inflator, with airbag pair
The energy-absorbing buffering of occupant's impact force, crimp shape are gradually compressed, and the airbag main leaf at crimp shape gradually connects with windshield
Touching, crimp shape form the tension for being parallel to windshield direction, and tension counteracts the decrement that crimp shape compression generates
Power.
The length of the outer drawstring is adjusted according to the angle and occupant space size of windshield.
The present invention compared with the existing technology, overhead type airbag apparatus pass through inside and outside drawstring under the action of, copilot side air bag
Expansion shape can be continual and steady, realizes self-sustained function, does not need to be supported from instrument board, get rid of instrument board and make
The influence of type design.The present invention adds outer drawstring on the outside of airbag, so that airbag is had not Tongfang by the outer drawstring of different location
To tension, generate the torque for resisting airbag rotation or control airbag and windshield contact position and area, it is not right to reduce
Claim support force.

Specific embodiment
The present invention is described further now in conjunction with attached drawing.
It when vehicle collides, is inflated from gas generator 4 to polyhedron airbag 8, airbag 8 is made to fill up copilot and wind
The space between glass 2 is kept off, occupant is protected.The design of airbag shape profile is true according to the upper trunk requirement of protection occupant
It is fixed.The front end of airbag 8 is contacted with windshield 2, and rear end is contacted with the head of occupant 6, neck, chest.Air bag absorbs occupant's impact energy
Amount length passes through interior 9 length adjustment of drawstring with occupant's contact position.
Since air bag moves to ceiling 5 from instrument board, instrument board is cancelled or is changed to expand driver leg space
Copilot side instrument 1,8 lower end of airbag can not be by contacting supporting and fixing for acquisition with instrument board.And the song of windshield 2
Face moulding forms it into left-right asymmetry support force.When the asymmetric support force and occupant's impact force of windshield 2 are made respectively
When front and rear portions for airbag 8, the torque for making airbag 8 around vehicle body direction of advance will form, the rotation of airbag 8 is caused to deviate protection
Position, so as to cause dummy's whiplash effect in experimentation.To solve the above-mentioned problems, the present invention installs on the outside of airbag 8
Outer drawstring 10.
Referring to 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 mounted in roof of the vehicle 5, and folded airbag 8 is placed in overhead type air bag module 3
Interior, the inside of airbag 8 is equipped with interior drawstring 9.Referring to Fig. 5, airbag is sewed by airbag main leaf 11 and airbag lateral plate 12.Airbag master
The outside of piece 11 is equipped with two fixing points, and the both ends of outer drawstring 10 are separately fixed in two fixing points, the length of outer drawstring 10
Less than the spacing of two fixing points, after airbag 8 is inflated, the airbag main leaf 11 of two fixing points is in crimp shape.
Referring to fig. 2, outer drawstring 10 is located at the bottom of airbag 8, and in 8 gas replenishment process of airbag, crimp shape is inside airbag
Except pressure, crimp shape also forms the tension F of vehicle body direction of advance, and tension F counteracts the asymmetry of the formation of windshield 2
Support force and occupant's impact force, reduce resulting turning moment, it is ensured that in automobile collision procedure, airbag 8 is without lateral
With the movement in vertical direction.The length of outer drawstring 10 is adjusted according to the angle and occupant space size of windshield 2.
Referring to Fig. 3, outer drawstring 10 is located on the airbag main leaf 11 towards occupant 6, and outer drawstring 10, which reduces airbag 8, to be unfolded
Power is swung up and down in journey, reduces the contact area of airbag 8 Yu windshield 2, reduces the asymmetry of the formation of windshield 2
Support force reduces the torque that airbag 8 is rotated to vehicle body direction of advance, and in 8 gas replenishment process of airbag, crimp shape is in airbag
Except portion's pressure, crimp shape also forms the tension F for being parallel to windshield direction, and tension F counteracts 6 head of occupant and body
The dry impact force for travelling forward and rotating reduces occupant injury.Simultaneously as reducing the impact force of occupant, further decrease
The torque for rotating airbag, it is ensured that in automobile collision procedure, airbag 8 is not lateral and vertical direction on movement, holding gas
Stabilization of the bag 8 in collision process.
Referring to fig. 4, outer drawstring 10 is located on the airbag main leaf 11 towards windshield 2, in 8 gas replenishment process of airbag, with
Energy-absorbing buffering of the airbag 8 to occupant's impact force, crimp shape gradually compressed, the airbag main leaf 11 at crimp shape gradually with
Windshield 2 contacts, and crimp shape forms the tension F for being parallel to windshield direction, and tension F counteracts crimp shape compression
The compression of generation is measured one's own ability.In this process, the airbag area contacted with windshield 2 gradually increases, and realizes to asymmetry
The control of support force, and then the torque for rotating airbag 8 is reduced, keep stabilization of the airbag 8 in automobile collision procedure.
