Abstract
The utility model discloses a novel automobile safety air bag, including air -bags, gas generator and air current guide housing, in air current guide housing locates air -bags, air current guide housing is the flexible fabric of U -shaped, air current guide housing go up distribute have with the gas outlet of air -bags intercommunication, gas generator locates the middle part in air current guide housing's U -shaped chamber, air current guide housing's edge and air -bags's inner wall are sewed up, the region that air -bags links to each other with air current guide housing both ends is equipped with the threadiness gas vent. The utility model discloses both ends at air current guide housing directly set up the threadiness gas vent, when gas pressure is enough big in air -bags, and in the produced gas of gas generator no longer can enter into air -bags, but direct discharge of threadiness gas vent that struts through the pressurized. The utility model adopts the above structure can ensure that the air -bags internal pressure can not be too high, produce secondary damage to the human body when avoiding popping out, buffering effect obtains guaranteeing.
Description
Technical field
The utility model relates to a kind of Novel automobile safety airbag.
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.
In order to ensure that air bag can be filled up, all can preset abundant gas generant in gas generator and guaranteeing to produce abundant gas.Due to when accident occurs by cause influences such as car body distortion, the space of airbag deployment is difficult to be guaranteed, partial picture lower gasbag is even merely able to the half size being deployed into design volume value, in the case, if all gas that gas generator produces all is filled in gasbag, gasbag internal pressure can be caused excessive, do not have due buffering effect.
Utility model content
For above technical matters, the utility model provides a kind of Novel automobile safety airbag, and this air bag can overcome the excessive problem of inflation pressure, and buffering effect is guaranteed.
The technical scheme that the utility model adopts for its technical matters of solution is:
A kind of Novel automobile safety airbag, comprise gasbag, gas generator and air-flow guide housing, air-flow guide housing is located in gasbag, described air-flow guide housing is U-shaped flexible fabric, air-flow guide housing is distributed with the air extractor duct be communicated with gasbag, gas generator is located at the middle part in the U-shaped chamber of air-flow guide housing, and the edge of air-flow guide housing and the inwall of gasbag are sewed up, and the region that gasbag is connected with air-flow guide housing two ends is provided with wire exhausr port.
As preferred embodiment, the two ends of described wire exhausr port are expanded into circular port.
As preferred embodiment, described wire exhausr port is made by stamping-out.
The beneficial effects of the utility model are: the utility model directly arranges wire exhausr port at the two ends of air-flow guide housing, when gaseous tension in gasbag is enough large, the gas that gas generator produces no longer can enter in gasbag, but is directly discharged by the wire exhausr port that pressurized struts.The utility model adopts said structure can guarantee that gasbag internal pressure can not be too high, avoids producing passive safety to human body when ejecting, and buffering effect is guaranteed.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present utility model.
Accompanying drawing illustrates: 1-gasbag, 2-gas generator, 3-air-flow guide housing, 4-air extractor duct, 5-wire exhausr port.
Detailed description of the invention
With reference to Fig. 1, a kind of Novel automobile safety airbag disclosed in the utility model comprises gasbag 1, gas generator 2 and air-flow guide housing 3.Can a large amount of gas of instantaneous generation after gas generator 2 starts, gas channeling cover 3, for carrying 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.
Air-flow guide housing 3 of the present utility model is U-shaped flexible fabric, air-flow guide housing 3 is distributed with the air extractor duct 4 be communicated with gasbag 1, gas generator 2 is located at the middle part in the U-shaped chamber of air-flow guide housing 3, the edge of air-flow guide housing 3 and the inwall of gasbag 1 are sewed up, and the region that gasbag 1 is connected with air-flow guide housing 3 two ends is provided with wire exhausr port 5.During work, when the pressure of gasbag 1 does not reach, wire exhausr port 5 entirety keeps sealing, and most of gas that now gas generator 2 produces all can enter in gasbag 1 from the air extractor duct 4 air-flow guide housing 3.When gasbag 1 internal pressure is enough large, wire exhausr port 5 can be backed down, and now gas can directly be discharged from wire exhausr port 5, no longer enters in gasbag 1.This structure guarantees that gasbag 1 pressure can not affect buffer action because pressure is excessive.
During concrete enforcement, wire exhausr port 5 can be obtained by the mode of stamping-out.In addition, the two ends of wire exhausr port 5 can be expanded into circular port, and this circular port can play the effect preventing wire exhausr port 5 from tearing, increasing the edge length of exhaust.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
