Description
Technical field
The present invention is about safe automobile air bag, especially with regard to the airbag structure providing occupant's front protecting.
Background technology
Safe automobile air bag is widely used among Hyundai Motor, to provide personnel protection.The process of its work is:
Collision scenario or similar dangerous time, sensor sensing motion change information on vehicle body and send excitation information to
The gas generating unit connected, and be inflated providing occupant with soft protection to air bag by it.Generally can be according to gas
Capsule is retrained and is provided the direction difference of protection, air bag is divided into frontal airbags and installing side airbag, such as, is arranged on direction
Dish neutralizes the frontal airbags providing the protection of face, chest positive restraint in mounting seat automobile instrument panel, and installs present
On chair or car door in order to provide chest, hip and the installing side airbag of head side confining guard.
Being determined by the main movement direction of vehicle body and the hip joint structure of human body, human body generally has relatively in front
The direction of big displacement, i.e. hip joint；And the displacement of side surface direction is less, although these less displacements are also to people
Body is extremely harmful.The biggest front displacement have impact on the frontal airbag of offer positive restraint protection accordingly
Structure.
For current frontal airbag opposite flank air bag, all there is bigger volume and thickness, with in order to just to buffer
The larger displacement in face also provides soft protection.But very important situation is: when human body frontal collisions to soft air bag,
Therefore the gas being positioned at air bag center will produce in surrounding due to the head impact by human body to moving around
Bigger gas pressure.The basic structure of frontal airbags the most of the prior art is to use the sewing of upper and lower two panels to form,
Concrete that is, use the front as head contact and carry out sewing as the reverse side back to human body and form, and stitching
Zygonema is located in the surrounding of air bag.The most in the above prior art, when human impact's air bag, gas will be from center
Collect and formed bigger local gas pressure to the surrounding with stitching thread, and have the anxiety causing sewing thread to rupture.
Meanwhile, this area there is also the technological improvement trend reducing cost, alleviating air bag total quality, and use
The textile material of lighter weight will make the increased risk that above-mentioned sewing thread ruptures, and is therefore also required to provide a kind of new
Airbag structure also can use the light-dutyest textile material without being destroyed by gas pressure.
Summary of the invention
The main purpose of this creation is to provide a kind of novel airbag structure, particularly frontal airbags, and it can bear
Keep complete from the shock impulse force of occupant, particularly avoid the surrounding at this air bag that breakage occurs；This is novel simultaneously
Airbag structure can use and be suitable for use with light-dutyer textile material, to reach to alleviate weight, reduce the purpose of cost；
It addition, the gasbag structure in the present invention also should have simple in construction, manufacture and feature easy for installation, with full
Foot utilizes on a large scale.
A kind of safe automobile air bag is provided for this present invention, it is characterised in that: it is made up of single piece of fabric material, described
The both ends of textile material relative to center ring around, and vertically by described both ends sew up to form barrel shape body, described bucket
The sidewall that cincture bucket wall is described air bag of type body, the first terminal surface of described barrel shape body becomes described air bag after closing
Front, the second terminal surface of described barrel shape body is all the gas generator of described airbag aeration and is connected.
Use the safe automobile air bag of said structure, particularly apply at the frontal airbags providing human body front protecting, its
Owing to not having sewing thread structure in the peripheral direction of air bag, therefore, when air bag is by human body frontal impact compressed gas
During body, airbag structure can't be destroyed by the pressure along air bag surrounding outward expansion, thus keeps the profile of air bag
Structure is to provide protection.Simultaneously because its profile is reliable, the air bag of this structure can also use light-duty textile material,
Such as, employing nylon66 fiber, the fabric of fiber number 235Dtex, the most cost-effective, it is more beneficial for the need of light-duty design
Want.

Detailed description of the invention
Refer to the stereoscopic mechanism schematic diagram of the air bag shown in Fig. 1, a kind of safe automobile air bag that the present invention provides,
It is made up of single piece of fabric material 1, the both ends of described textile material 1 relative to center ring around, and vertically by described
Both ends are sewed up to form barrel shape body, the sidewall that cincture bucket wall is described air bag of described barrel shape body, described barrel shape body
First terminal surface 11 becomes the front of described air bag after closing, and the second terminal surface 12 of described barrel shape body is all described
The gas generator (not shown) of airbag aeration is connected.
Using the safe automobile air bag of said structure, owing to it is made up of the textile material of monolithic, it is the most existing
Biplate suture texture structure has simple in construction, processing quality is easy to control and ensures.Its axial along described barrel shape body simultaneously
Having the sidewall sections 10 of overlap on direction, the sidewall sections of described overlap is then sewed up by sewing thread, on realizing
The air bag being made up barrel shape body structure of single piece of fabric material 1 stated.
Safe automobile air bag in the present invention, particularly apply provide human body front protecting frontal airbags, its due to
Not sewing thread structure, the sewing thread of lap the most in axial direction, its sewing in the peripheral direction of air bag
The direction of line is illustrated in figure 2 direction radially, axial sewing thread in the prior art of its relative double-sheet arrangement, can
To resist bigger expanding radial force.Therefore, when air bag is by human body frontal impact compressed gas, along air bag four
Airbag structure can't be destroyed by the pressure of all outward expansion, thus keeps the contour structures of air bag to provide protection.
Simultaneously because its contour structures is reliable, the air bag of this structure also achieves and can use light-duty textile material system
The purpose made, for example with nylon66 fiber, the fabric of fiber number 235Dtex.The most cost-effective, it is more beneficial for lightness
The needs of design.
In an embodiment as illustrated in figure 3, the closing of described first terminal surface 11 can use multiple sealing technique,
Preferably it is sewed up to be formed through sewing thread 110 and closes.Meanwhile, for convenience of sewing thread 110 described in actually used effect
It is positioned at inside described air bag.
As in Figure 1 and Figure 2 shown in the direction of arrow, there is at described first terminal surface 11 first indent of relative air bag
Part 111, described first female parts 111 forms closing with the first terminal surface 11 through sewing thread 110 stitching, so that
Obtain the cross section less than described air bag center of the cross section at the first terminal surface.Preferably, described first female parts
It is a pair region positioned opposite on described first terminal surface.This female parts is relative to the first terminal surface 11 as shown in Figure 2
Positioned opposite.
Fig. 4 is the cross sectional representation of the second terminal surface in this creation, as shown in Figure 4, at described second terminal surface 12
There is uniform second female parts 121, so that the gas that described second terminal surface 12 is all described airbag aeration is sent out
Raw device (not shown) is in mating connection.In the side schematic view of the disclosed air bag of Fig. 3, can
To be clearly seen that, the rear end of whole air bag, i.e. gradually narrow near the second terminal surface 12 end, and formed on air bag
Fold 120, described second terminal surface 12 then forms the size that same gas generator (not shown) is in mating connection.
