Description
Technical field
The utility model relates to a kind of air bag device being provided on automobile, relates in particular to a kind of classification and launches side air bag device.
Background technology
Side air bag device is arranged in automotive seat, prevents that passenger's chest, belly are subject to the shock of hard thing in outside invader or car, for example car door in automobile side impact accident.In the time bumping, side air bag device can be inflated by gas filled device in airbag, makes side air bag launch and cover belly, chest completely from seat, protection passenger's belly, chest.
Existing side air bag is to be made up of airbag, inflatable component and the drawstring or the line of weakness that are fixed on airbag edge.In the time that producer is given vent to anger, due to the corresponding airbag internal upper part of generator exports, therefore airbag upper position is first full of, is full of after bottom and midway location, the pressure on airbag top increases gradually thereupon, the hardness on airbag top is also increasing, the antagonistic force that passenger's neck, head are subject to is increased, easily passenger's neck and head are damaged.
Utility model content
The classification that the purpose of this utility model is to provide a kind of adjustable airbag internal pressure and gas flow launches side air bag device; this side air bag device can be avoided due to the excessive passenger's of the hurting neck of airbag internal upper part pressure, head; and under the prerequisite of first-stage generator; realize the effect of multiple development, thus can more effective protection occupant.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of classification launches side air bag device, comprise airbag main leaf, the doubling of airbag main leaf is sewed up and is formed airbag, in airbag, be provided with gas generator, airbag is provided with deflation hole, its special character is: described gas generator outside is arranged with shunting pad, shunting pad is sewed up and is fixed on described airbag main leaf, the skin of shunting pad and internal layer are respectively small one and large one two-layer pieces of cloth of doubling, two-layer pieces of cloth and described airbag main leaf are equipped with gas generator mounting hole and the producer screw perforation of coincidence corresponding to the position of described gas generator, little pieces of cloth surrounding in two-layer pieces of cloth is sewed up completely, large pieces of cloth one side in two-layer pieces of cloth is alignd and sews up with described little pieces of cloth, the other end extends little pieces of cloth outside and local stitching forms upper air extractor duct and lower air extractor duct, upper air extractor duct length is less than lower air extractor duct, described large pieces of cloth and little pieces of cloth middle part are equipped with can be broken through and break through by gas the cross tear line that after-opening is greater than described upper air extractor duct and lower air extractor duct.
Described large pieces of cloth, little pieces of cloth periphery are sewed up with described airbag main leaf respectively.
The gas generator mounting hole of described large pieces of cloth, little pieces of cloth and described airbag main leaf and producer screw perforation are around sewed up.
The beneficial effects of the utility model are: because corresponding gas generator place in airbag is provided with shunting pad, the gaseous tension of discharging in the time that gas generator detonates is very big, cross tear line on little pieces of cloth can be torn rapidly, airbag can reach the expanded position of design, and then the cross tear line on large pieces of cloth is torn, airbag just can arrive airbag upper, middle and lower by gas distribution by this project organization, and can according to designer's wish allow gas first arrive airbag in, bottom, then to top; Because the throughput size of cross tear line after tearing is greater than upper and lower air extractor duct, therefore be filled with the gas multiple pressure power at airbag middle part by cross tear line large, airbag middle part is first full of, giving vent to anger of two ends is young, after few pressure of giving vent to anger is little, be full of, belly, chest that can more effective protection passenger be avoided like this under improper sitting posture due to the excessive passenger's of the hurting neck of airbag upper pressure, head; Also can, to the passenger of improper sitting posture or because collision movement provides protection to passenger's neck in this region, increase the protection effect of side air bag to human body simultaneously.

Detailed description of the invention
With reference to the accompanying drawings the utility model is described in further detail below.
As Figure 1-Figure 4, classification described in the utility model embodiment launches side air bag device, comprise airbag main leaf 101, 101 doublings of airbag main leaf are sewed up and are formed airbag 1, in airbag 1, be provided with gas generator 2, airbag 1 is provided with deflation hole 102, described gas generator 2 outsides are arranged with shunting pad 3, the skin of shunting pad 3 and internal layer are respectively small one and large one two-layer pieces of cloth of doubling, two-layer pieces of cloth and described airbag main leaf 101 are equipped with gas generator mounting hole 8 and the producer screw perforation 9 of coincidence corresponding to the position of described gas generator 2, the gas generator mounting hole 8 of two-layer pieces of cloth and described airbag main leaf 101 and producer screw perforation 9 are around sewed up, two-layer pieces of cloth are sewed up with described airbag main leaf 101 respectively, little pieces of cloth 301 surroundings in two-layer pieces of cloth are sewed up completely, align and sew up with described little pieces of cloth 301 in large pieces of cloth 302 one end in two-layer pieces of cloth, the other end extends little pieces of cloth 301 outsides and local stitching forms upper air extractor duct 4 and lower air extractor duct 5, upper air extractor duct 4 is less than lower air extractor duct 5, described little pieces of cloth 301 and large pieces of cloth 302 middle parts are equipped with can be broken through and break through by gas little pieces of cloth cross tear line 6 and the large pieces of cloth cross tear line 7 that after-opening is greater than described upper air extractor duct 4 and lower air extractor duct 5.
As shown in Figure 5, in the time that gas generator 2 detonates, the gas of discharge enters in little pieces of cloth 301.Under gaseous tension effect, the little pieces of cloth 301 rapid aerificatioies in inner space, reach after certain pressure, and little pieces of cloth cross tear line 6 is torn rapidly (first order 1st), and gas enters into large pieces of cloth 302 by little pieces of cloth cross tear line 6 places of tearing.In large pieces of cloth 302, it not enclosure space, leave respectively air extractor duct 4 and lower air extractor duct 5, first gas flows out a small amount of gas by upper air extractor duct 4 and lower air extractor duct 5, because aeration speed is higher than the speed several times of giving vent to anger, so under gaseous tension effect, large pieces of cloth cross tear line 7 can be torn to (second stage 2nd), then tear place by upper air extractor duct 4, lower air extractor duct 5 and large pieces of cloth cross tear line 7 gas distribution is arrived to airbag 1 upper, middle and lower (third stage 3rd), airbag 1 can launch according to the mode of design like this.Because lower air extractor duct 5 and large pieces of cloth cross tear line 7 throughput after tearing is greater than upper air extractor duct 4; therefore by lower air extractor duct 5 is many with the gas that large pieces of cloth cross tear line 7 is filled with airbag 1 middle part and bottom, pressure is large; airbag 1 middle part and bottom are first full of; upper air extractor duct 4 is little; give vent to anger less, pressure is full of after little; like this can be more effective protection passenger's belly, chest, also can avoid improper sitting posture occupant due to the airbag excessive passenger's of the hurting neck of 1 upper pressure and head simultaneously.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
