Abstract
The invention discloses a kind of high temperature resistant automobile safety air bag, comprise gasbag, gas generator and air bag inner bag, described air bag inner bag is located in gasbag, air bag inner bag is distributed with air extractor vent, the air extractor duct of gas generator extends in air bag inner bag, and the madial wall of described air bag inner bag is provided with black absorbing material layer.The present invention is provided with air bag inner bag, air bag inner side of liner is provided with black absorbing material layer, the High Temperature Gas cognition that gas generator produces when starting is introduced in air bag inner bag, the heat that gas comprises can be absorbed by black absorbing material layer, the gas temperature entered in gasbag from air extractor vent is reduced greatly, heats up too high and damaged after solving gasbag inflation or human body caused to the problem of secondary injury; Air bag inner bag of the present invention can also play the effect of air guide.
Description
Technical field
The present invention relates to a kind of safe automobile air bag, be specifically related to a kind of high temperature resistant automobile safety air bag.
Background technology
Air bag system is a kind of protection system of passive satety, it and seatbelt with the use of, actv. Anti-bumping protection can be provided for occupant.
When automobile crashes in the process of moving, various sensor response, electronic controller works then, controls gas generator and starts.Gas generator receives pilot gas propellant after signal; produce a large amount of gas; air bag is launched rapidly within the extremely short time; elastic air cushion is formed at the front portion of chaufeur or occupant, sidepiece or top; apparatus with shock absorbing; thus effectively protect human body head and chest, make it avoid injury or alleviate extent of injury.
The gas that gas generator produces is high-temperature gas, if these gases are directly filled with in gasbag, the temperature of gasbag can be made greatly to raise, and except causing gasbag breakage, also can produce secondary injury to the human body touched.The mode that the general air extractor duct place at gas generator arranges heat-proof device at present makes the gas temperature sprayed reduce, but the limited efficiency of this heat-proof device, and cost is higher.
Summary of the invention
For above technical matters, the invention provides a kind of Novel automobile safety airbag, structure is simple, can overcome the problem that temperature after gas inflated is too high, guarantee that human body can not be subject to secondary injury.
The technical scheme that the present invention adopts for its technical matters of solution is:
A kind of high temperature resistant automobile safety air bag, comprise gasbag, gas generator and air bag inner bag, described air bag inner bag is located in gasbag, air bag inner bag is distributed with air extractor vent, the air extractor duct of gas generator extends in air bag inner bag, and the madial wall of described air bag inner bag is provided with black absorbing material layer.
As preferred embodiment, described black absorbing material layer is arranged by the mode of spraying.
As preferred embodiment, the shape of described air bag inner bag is spherical.
As preferred embodiment, the maximum volume of described air bag inner bag is the 30%-50% of gasbag maximum volume.
The invention has the beneficial effects as follows: the present invention is provided with air bag inner bag, air bag inner side of liner is provided with black absorbing material layer, the High Temperature Gas cognition that gas generator produces when starting is introduced in air bag inner bag, the heat that gas comprises can be absorbed by black absorbing material layer, the gas temperature entered in gasbag from air extractor vent is reduced greatly, heats up too high and damaged after solving gasbag inflation or human body caused to the problem of secondary injury; Air bag inner bag of the present invention can also play the effect of air guide.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present invention.
Accompanying drawing illustrates: 1-gasbag, 2-gas generator, 3-air bag inner bag, 4-air extractor vent, 5-black absorbing material layer.
Detailed description of the invention
With reference to Fig. 1, a kind of high temperature resistant automobile safety air bag disclosed by the invention forms primarily of gasbag 1, gas generator 2 and air bag inner bag 3.Air bag inner bag 3 is located in gasbag 1, air bag inner bag 3 is distributed with air extractor vent 4, and the air extractor duct of gas generator 2 extends in air bag inner bag 3.When gas generator 2 starts, the gas produced is introduced in air bag inner bag 3, then is passed in gasbag 1 through air extractor vent 4.Therefore air bag inner bag 3 can carry out water conservancy diversion to gas, makes gas can be charged to the various piece of gasbag 1 equably, makes the gasbag after inflation 1 rigidity consistent, plays better protected effect.In order to reach good air guide effect, the structure of air bag inner bag 3 is generally set to spherical.In addition, the maximum volume of air bag inner bag 3 is generally set to the 30%-50% of gasbag 1 maximum volume.
As previously mentioned, the gas that gas generator 2 produces is introduced into air bag inner bag 3, in order to the heat comprised gas absorbs, guarantee that gas can not cause intensification to gasbag 1 after being filled into gasbag 1, the present invention is provided with black absorbing material layer 5 on the madial wall of air bag inner bag 3.The material realization that this black absorbing material layer 5 general heat-conducting effect is good, can be delivered to heat on material layer when gas touches this material layer rapidly.During concrete enforcement, black absorbing material layer 5 can be arranged by the mode of spraying.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
