Abstract
The invention relates to an air cell device that can control airflow direction, comprising a module bracket that is provided with an air generator and an air bag, the air bag is provided with a drawstring, a piece of cloth is arranged in the air bag along the vertical direction, one end of the drawstring is connected with the cloth, the other end is fixed on the root of the air bag, the middle of the front of the air bag is connected with the cloth by lacerable sewing thread or adhesive tape. The air cell device has the advantages as follows: the device has simple structure and can realize that two sides of the air bag are expanded firstly, and then the middle part is expanded, thus controlling the expanding speed of the middle in the front of the air bag, reducing momentary impact on a passenger in the expanding process of the air bag and avoiding the damage to the passenger in the initial stage of expanding; the device can provide protection for the passenger of normal sitting posture after complete expansion, the vehicle structure does not need to be changed, the device is compatible with the current safety air cell system, high protection property can be realized only by the current igniting circuit, and the device can satisfy higher and higher demands of consumers on passive safety .
Description
Technical field
The present invention relates to a kind of air bag device that is provided on the automobile, particularly a kind of airbag apparatus of airflow direction controllable air.
Background technology
Common safety air bag can go out very big energy in abrupt release in the starting stage of launching, and can produce very high impulsive force to the occupant.If the occupant is at the stages of deployment contact air bag of air bag, very high air bag impulsive force can cause the occupant to come to harm.Therefore, the common safety air bag protection that can not suit for the forward less occupant of sitting posture even can cause extra injury.In order to address this problem; the protection that realization suits to different occupants and produced intelligent safety air bag; intelligent safety air bag need rely on various occupant sensors that the occupant is judged; and then the control air bag launches with different conditions; so intelligent bag structure complexity; involve great expense, installation and maintenance inconvenience, and body structure had specific (special) requirements.
Summary of the invention
The objective of the invention is to solve the problems referred to above that prior art exists; provide a kind of simple in structure; the development rate of may command airbag; reduce in the airbag deployment process instant impact to the occupant; the nearer occupant of air bag that avoids adjusting the distance damages, simultaneously the airbag apparatus of the airflow direction controllable air that also can effectively protect the occupant of normal sitting position.
The present invention is achieved in that it has a module carrier, on module carrier, be provided with gas generator and airbag, in airbag, be provided with drawstring, its special character is: vertically be provided with the cloth sheet in airbag, described drawstring one end is connected on the cloth sheet, the other end is fixed on the airbag root, but airbag forward, central part and cloth sheet are connected by thread line or adhesive tape of tear seam.
The airbag apparatus of above-mentioned airflow direction controllable air, drawstring are connected an end and are positioned at cloth sheet middle part with the cloth sheet.
The airbag apparatus of above-mentioned airflow direction controllable air, the upper and lower edge of described cloth sheet is affixed with airbag inner top and bottom respectively, launches with control airbag both sides in advance.
The airbag apparatus of above-mentioned airflow direction controllable air, the edge of described cloth sheet respectively with airbag in around affixed, be respectively equipped with deflation hole in the both sides of cloth sheet, launch with control airbag both sides in advance.
Advantage of the present invention is: simple in structure, cost is low, the direction of air-flow when launching by the control airbag, can realize the expansion earlier of airbag both sides, centre portion launches again, thereby the development rate of control airbag anteriomedial position reduces in the airbag deployment process instant impact to the occupant, thereby avoids air bag launching adjust the distance nearer occupant's injury of starting stage; Also can provide protection after launching fully to the occupant of normal sitting position; this device need not vehicle structure is changed; and compatible mutually with current air bag system, only use current ignition circuit can realize higher protective value, can satisfy customer's requirement more and more higher to passive security.

Among the figure: 1-airbag, 2-cloth sheet, 201-sewing thread, 3-drawstring, 4-gas generator, 5-module carrier, 6-occupant.
The specific embodiment
As Fig. 1-shown in Figure 4, the present invention has a module carrier 5, on module carrier 5, be fixed with gas generator 4 and airbag 1, in airbag 1, be provided with one or more drawstring 3, in airbag 1 middle part vertically (promptly with the perpendicular or subvertical direction of the expansion direction of airbag 1) be provided with cloth sheet 2.Captive joint by sewing thread with the bottom with airbag 1 inner top respectively in the upper and lower edge of cloth sheet 2, described drawstring 3 one ends are connected cloth sheet 2 middle parts, drawstring 3 other ends are fixed on airbag 1 root, but airbag 1 forward, central part and cloth sheet 2 are connected (also can pass through adhesive tape bonding herein) by the tear seam line 201 of threading.
When collision happens, gas generator 4 charges into gas in the airbag 1, at the 1 expansion initial stage of airbag, air-flow flows into the front end both sides of airbag 1 between the both sides of the edge of cloth sheet 2 and airbag 1, line 201 can not be torn but tear seam is threaded, what cloth sheet 2 and drawstring 3 can be controlled airbag 1 middle part is shaped as inner concavity (as shown in Figure 1), and the development rate that makes airbag 1 middle part is slow around relatively, alleviates the close occupant's 6 of 1 pair of sitting posture of airbag direct impact; Along with airbag 1 internal pressure increases gradually, sewing thread 201 to be torn, cloth sheet 2 loosens the constraint to airbag 1 middle part, and airbag 1 middle part begins to be expanded to net shape (as shown in Figure 2), thereby realizes the protection to normal occupant.
As Fig. 5-shown in Figure 8, the edge of described cloth sheet 2 respectively with airbag 1 in around affixed by sewing thread, be respectively equipped with deflation hole 202 in the both sides of cloth sheet 2.At the 1 expansion initial stage of airbag, air-flow is through the front end both sides of the both sides of cloth sheet 2 deflation hole 202 inflow airbags 1, and other is with embodiment 1.
