Description
Technical field
The present invention relates to vehicle safety device technical field more particularly to a kind of automobile side safety air curtain device and its
Production method.
Background technique
Safe automobile air bag includes frontal airbags and side air bag, and the working principle of safe automobile air bag is, in running car
In the process, sensing system analyzes these information by control device constantly to control device transmission speed change information
Judgement controls dress if the acceleration surveyed, velocity variable or other indexs are more than that predetermined value is really collided
Set and issue ignition order or sensor to gas generator and directly control igniting, occur explosive reaction after igniting, generation gas or
Compressed gas in air accumulator is released full of collision airbag.When occupant and airbag contact, is compressed by airbag and absorb collision
Energy achievees the purpose that protect occupant.
Side safe air curtain would generally be arranged in the lateral roof of vehicle, to have percussion in side collision or when overturning etc.
When protect occupant, this safe air curtain, which mainly has, folds the gentle body generator of bag body, when encountering side impact, gas generator
Gas is produced, bag body expansion protection occupant is folded.But existing side safe air curtain has the disadvantage in that in 1) side safe air curtain often
Containing a plurality of curved suture, round on-inflatable area is often contained in the both ends or one end of curved suture, for larger covering occupant protection
Region, this circle on-inflatable area generally requires diameter to should not exceed 50mm, but this round on-inflatable area is located at car steering
Room and back court position when in case of traffic accident, if head part just collides with this region, inevitably go out
Existing danger, and during side curtain airbag expansion, become region of stress concentration around this round on-inflatable area, is also easy to happen and tears
The phenomenon that strutting is split, and then gas leakage leads to the reduction of gas curtain protective value；2) structure for the side curtain airbag that different automobile types are used is different,
Internal gas-filled protective region needs to be customized according to different automobile types, and the versatility of structure design is poor, makes production efficiency
It reduces.
To sum up, a kind of simple and stable structure is designed, crash protection region is larger, the versatile side curtain airbag of structure design
Device is traditional side curtain airbag area for improvement.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of automobile side safety air curtain devices, mainly solve
The problem of traditional side curtain airbag crash protection region is limited and structural instability, it is therefore intended that, by design it is a kind of have it is new
Suture texture side airbag air curtain device, whole suture texture simple and stable increases the protection zone of side collision,
No non-inflatable area influences the adjustment of design protection range, and its suture way is not influenced by vehicle different configuration shape, is mentioned
High structure versatility.
To achieve the above object, the technical solution adopted by the present invention to solve the technical problems is: the automobile side peace
Full air curtain device, which is characterized in that setting is in car body two sides, including airbag ontology and connection pieces of cloth, the airbag body interior
For inflating cavity, the connection cloth on piece is arranged venthole, sutures after the connection pieces of cloth annular closure with the airbag ontology
The inflating cavity is set to form the primary and secondary cavity structure being connected together.
Further, the airbag ontology includes main pieces of cloth I and main pieces of cloth II, II edge of the main pieces of cloth I and main pieces of cloth
It is stitched together, the setting open at one end of the airbag ontology, and the opening connects gas generator.
Further, notch section, the edge seal seam of the notch section are provided on the main pieces of cloth I or main pieces of cloth II
It closes, and the side of the notch section and automotive seat is oppositely arranged.
Further, the inflating cavity includes the receiving positioned at the accommodating cavity I of driver's compartment and positioned at heel row occupant area
Cavity II is connected between the accommodating cavity I and accommodating cavity II by filling channel.
Further, the accommodating cavity I is arranged between automobile A column and B column, and the accommodating cavity II is arranged in automobile
Between B column and C column.
Further, the accommodating cavity I is arranged between automobile A column and B column, and the accommodating cavity II includes by filling
The connected two chambers in gas channel, described two chambers are separately positioned between automobile B-column and C column, between automotive C column and D column.
Further, the connection pieces of cloth include rectangle pieces of cloth, and the rectangular cloth on piece is evenly equipped with multiple ventholes, described
The upper and lower ends of rectangle pieces of cloth are respectively arranged with bar shaped sawtooth, and the bar shaped sawtooth is after the folding of its root and in airbag ontology
Parietal suture closes.
Further, the width of the rectangle pieces of cloth is set as 80mm~100mm.
Further, the connection pieces of cloth are provided with multiple, and are located in the accommodating cavity I and accommodating cavity II, institute
It states and is sewn on airbag ontology after being closed between the connection pieces of cloth in accommodating cavity I or accommodating cavity II.
A kind of production method of the automobile side safety air curtain device, which comprises the following steps:
1) it cuts base fabric and obtains main pieces of cloth I, main pieces of cloth II and connection pieces of cloth, and cut out in the upper and lower ends of connection pieces of cloth
Bar shaped sawtooth cuts venthole at the middle part of connection pieces of cloth；
2) the bar shaped sawtooth that will connect the upper and lower ends of pieces of cloth folds, after being closed multiple connection pieces of cloth annulars from inside to outside
It is sewn between main pieces of cloth I and main pieces of cloth II；
3) it will be sutured after the positioning of the edge of main pieces of cloth I and main pieces of cloth II, and reserve the opening connecting with gas generator.
The beneficial effects of the present invention are:
