Abstract
The utility model belongs to the technical field of passive safety device technique and specifically relates to a curtain formula air bag's skirt form air guide device, including air guide mechanism and protection mechanism, protection mechanism makes up in the inboard of air guide mechanism, and air guide mechanism is the toper, and the protection mechanism middle part is equipped with skirt form fold structures, and protection mechanism's lower part is equipped with the opening, and protection mechanism's shape is matchd with gas generator's shape. Compared with the prior art, the utility model, comprise through the sewing independent air guide mechanism and protection mechanism, air guide mechanism is the toper space that single air guide cloth piece fifty percent discount formed, and protection mechanism protection cloth piece curls and forms, the protection mechanism middle part is equipped with skirt form fold structures, and protection mechanism has reduced the direct impact power that air guide mechanism received the gas generator air current, has avoided air guide cloth piece or suture and air current direct contact to avoided the disrumpent feelings condition of sewing thread or base cloth to take place.
Description
Technical field
The utility model relates to passive safety feature technical field, specifically a kind of skirt gas operated device of curtain air bag.
Background technology
The effect of curtain air bag is: when automobile generation side collision, for occupant provides necessary protection.Because the gas filled device of curtain air bag is usually less, cannot ensure that each position of curtain type gas bag is inflated simultaneously, so usually carry out air guide when gas generator is given vent to anger.
Existing gas operated device has metal conduit, and gas generator gas is inflated to pouch by the air gate of metal conduit.But metal conduit cost is higher, so a large amount of pouch pieces of cloth that adopt are sewn into air guide mechanism at present, but because pouch pieces of cloth ability to bear is far below metal conduit, so the pieces of cloth of air guide mechanism or suture may be destroyed.
Therefore, the skirt gas operated device designing a kind of curtain air bag that the pieces of cloth of air guide mechanism or suture can be avoided to be destroyed is needed.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of skirt gas operated device of the curtain air bag that the pieces of cloth of air guide mechanism or suture can be avoided to be destroyed.
In order to achieve the above object; the utility model is a kind of skirt gas operated device of curtain air bag; comprise air guide mechanism and protection mechanism; it is characterized in that: protection mechanism makes the inner side in air guide mechanism; air guide mechanism is tapered; be provided with skirt pleated structure in the middle part of protection mechanism, the bottom of protection mechanism is provided with opening, the shape of protection mechanism and the form fit of gas generator.
Described air guide mechanism is folded to form cone space by air guide pieces of cloth.
By protecting, pieces of cloth are curling to be formed described protection mechanism, protects the arranged on left and right sides limit of pieces of cloth overlapping and adopts suture to fix.
In described protection mechanism, gas generator is installed.
Described air guide mechanism is fixed on curtain air bag.
The utility model compared with the existing technology; by independently air guide mechanism and protection mechanism are consisted of sewing; air guide mechanism is the cone space that single air guide pieces of cloth are folded to form; pieces of cloth are curling forms in protection mechanism protection; skirt pleated structure is provided with in the middle part of protection mechanism; protection mechanism reduces the direct impulsive force that air guide mechanism is subject to gas generator air-flow, avoids air guide pieces of cloth or suture directly contacts with air-flow, thus avoids sewing thread or the disrumpent feelings situation of base cloth occurs.

Detailed description of the invention
Now by reference to the accompanying drawings the utility model is described further.
See Fig. 1-Fig. 3, the utility model is a kind of convolution gas operated device of curtain air bag, comprises air guide mechanism and protection mechanism.Air guide mechanism 2 is fixed on curtain air bag 1.Protection mechanism 3 makes the inner side in air guide mechanism 2, is provided with gas generator 4 in protection mechanism 3.
See Fig. 8, air guide mechanism 2 is tapered, and air guide mechanism 2 is folded to form cone space by air guide pieces of cloth 7.
See Fig. 4-7, be provided with skirt pleated structure 6 in the middle part of protection mechanism 3, the bottom of protection mechanism 3 is provided with opening, and protection mechanism 3 is formed by protection pieces of cloth 5 convolution.Protect the arranged on left and right sides limit of pieces of cloth 5 overlapping and adopt suture to fix.The shape of protection mechanism 3 and the form fit of gas generator 4.Be provided with the forced airflow that protection mechanism 3 available buffer of skirt pleated structure 6 is instantaneous, and air-flow is imported air guide mechanism 2.
It is quick-fried that the utility model works as gas generator 4; air-flow first can surge protection mechanism 3; protection mechanism 3 keeps out the instantaneous energy of gas generator 4 quick-fried generations; air-flow flows into air guide mechanism 2 through protection mechanism lower openings place afterwards; enter in curtain air bag 1 through air guide mechanism about 2 two outlets, be full of gas curtain.
