Abstract
A kind of frontal airbags structure, including upper bag sheet and lower bag sheet, it is characterized in that: the upper bag sheet is sutured with lower bag sheet periphery by high-strength nylon sewing thread, on the basis of airbag outer edge line, it is offset inward sewing reduction nylon wire in the circular trace of 50-100mm distance, form first of airbag weakened line, on the basis of first of airbag weakened line, sewing reduction nylon wire in the circular trace of 50-100mm distance is deviated inwardly, form second airbag weakened line, similarly, on the basis of second airbag weakened line, deviate sewing reduction nylon wire in the circular trace of 50-100mmm distance inwardly again, form third road airbag weakened line.The present invention will not make too fast being full of of air bag reduce the risk that dummy's face is directly impacted by air bag in place, and then effectively protect the head of driver；Meanwhile this airbag with weakened line form can replace the pulling belt structure of traditional frontal airbags, the cost for not only reducing the sewing difficulty of air bag, and reducing airbag itself.
Description
Technical field
The present invention relates to a kind of safe automobile air bag more particularly to frontal airbag structures.
Background technique
In order to reduce the injury that driver is subject to when head-on crash occurs for automobile, automobile is equipped with frontal airbag.
Traditional frontal airbag receives the signal detonation of sensor when head-on crash occurs for vehicle, and air bag can be first to driver side
To expansion, simultaneously because the effect of contraction by drawstring, so that air bag presentation circle or polygon after expansion, and this air bag
Structure can be in the very short time since air bag itself only leans on the constraint of drawstring in driver's range direction disk more recently condition
It inside expands in place, can have the risk that air bag directly impacts driver's face, and then damage to the head of driver.
Summary of the invention
The present invention be directed to the above problems, and provide a kind of frontal airbag structure, which compensates for existing front
Deficiency in airbag technology reduces the risk of driver head's damage.
The technical scheme is that
A kind of frontal airbags structure, including upper bag sheet and lower bag sheet, are characterized in that: the upper bag sheet and lower bag sheet week
Side is sutured by high-strength nylon sewing thread, on the basis of airbag outer edge line, is offset inward the circle of 50-100mm distance
Sewing reduction nylon wire, forms first of airbag weakened line, on the basis of first of airbag weakened line, inside lateral deviation on shape track
Sewing reduction nylon wire in the circular trace of 50-100mm distance is moved, second airbag weakened line is formed, similarly, with second gas
On the basis of bag weakened line, then sewing reduction nylon wire in the circular trace of offset 50-100mmm distance inwardly, form third road
Airbag weakened line.
Further, first of airbag weakened line, second airbag weakened line and third road airbag weakened line is inclined
Moving distance is respectively 50-70mm.
Further, first of airbag weakened line, second airbag weakened line and third road airbag weakened line is inclined
Shifting is equidistant.
Further, the intensity of the high-strength nylon sewing thread is 103-107N, and the intensity of the weakened line is 21N-
25N。
The beneficial effects of the present invention are:
When head-on crash occurs for vehicle, gas is filled with airbag, airbag by the frontal airbag igniting, generator
Three airbag weakened line can be torn step by step inside-out, will not thus make air bag is too fast to be full of in place, reduce dummy
The risk that face is directly impacted by air bag, and then effectively protect the head of driver；Meanwhile it is this linear with weakening
The airbag of formula can replace the pulling belt structure of traditional frontal airbags, not only reduce the sewing difficulty of air bag, and reduce gas
The cost of bag itself.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of corresponding embodiment 1 of the present invention；
Fig. 2 is Fig. 1 left view；
Fig. 3 is the structural schematic diagram of this hair corresponding embodiment 2
In figure: 1. high-strength nylon sewing threads, 2. generators, 3. first of airbag weakened line, the reduction of 4. second airbags
Line, 5. third road airbag weakened line, 6. airbags upper piece, 7. airbag bottom sheet.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples:
Embodiment 1
As depicted in figs. 1 and 2, air bag of the invention is stitched by round airbag upper piece 6 and airbag bottom sheet 7 by high-strength nylon
Line 1 of threading sutures, and generator 2 is arranged at 7 center of airbag bottom sheet.On the basis of airbag outer edge line, it is offset inward 50-
Sewing reduction nylon wire, forms first of airbag weakened line 3, with first in the circular trace of 100mm distance (offset distance d1)
On the basis of road airbag weakened line, sewing reduction nylon in the circular trace of 50-100mm distance (offset distance d2) is deviated inwardly
Line, formed second airbag weakened line 4, similarly, on the basis of second airbag weakened line, then inwardly offset 50-100mm away from
Sewing reduction nylon wire, forms third road airbag weakened line 5 in circular trace from (offset distance d3).The high-strength nylon
The intensity of sewing thread is 103-107N, and the intensity of the reduction nylon wire is 21-25N
Further, first of airbag weakened line, second airbag weakened line and third road airbag weakened line is inclined
Moving distance d1, d2 and d3 is respectively 50-70mm.
Further, first of airbag weakened line, second airbag weakened line and third road airbag weakened line is inclined
Shifting is equidistant and is 60mm.
Further, the intensity of the high-strength nylon sewing thread is 105N, and the intensity of the reduction nylon wire is 23N.
When head-on crash occurs for vehicle, gas is filled in airbag by air bag ignition, generator 2, due to there is three airbags
The presence of weakened line, airbag can be inside-out step by step by third road airbag weakened line 5, second airbag weakened line 4, third road gas
Bag weakened line 3 is torn, and will not thus make air bag is too fast to be full of in place, reduces dummy's face directly by air bag impact
Risk, and then effectively protect the head of driver.
Implement Li 2
As shown in figure 3, air bag of the invention passes through high-strength nylon sewing thread by polygon airbag upper piece 6 and airbag bottom sheet
1 sutures, and the present embodiment is octagon.On the basis of eight shape inscribed circles, reduction of sewing in the circular trace that is offset inward
Nylon wire forms first of airbag weakened line 3, other same as Example 1.
