Abstract
The utility model discloses an aerify reliable car air bag, including air -bags, gas generator and air current direction bag, in air -bags was located to air current direction bag, gas generator located in the air -bags and through air current direction bag parcel, air current direction bag is made for flexible fabric, and the sack edge of air current direction bag is sewed up on air -bags's inner wall, and bag end department of air current direction bag is equipped with the breach, is connected with the closing cap through lacerable suture on the breach, it has the blow vent to gather on air current direction bag and the closing cap. The utility model discloses an air current guide structure can split its guide effect of back and also can be kept with the division of predetermined mode when receiving too high gas shock power, ensures that air bag aerifys reliably.
Description
Technical field
The utility model relates to a kind of Novel automobile safety airbag, is specifically related to a kind of inflation failure-free safe automobile 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 produced to make gas generator is more uniformly filled in gasbag, generally all airflow guiding device can be provided with in current gasbag, these guide piecees are directly wrapped in outside gas generator, carry out water conservancy diversion by vent provided thereon to gas.When gas generator starts, its gas produced generally all can be concentrated from front ejection, and gas can be distributed to all directions and is passed in gasbag from each vent after spraying forward under the stop of guide piece under normal circumstances.But the gas production process of gas generator is a uncontrollable process, under partial picture, gas outwards can spray with the intensity exceeding expected value, can produce the impulsive force exceeding guide design intensity after gas touches guide piece makes guide piece damaged, integral structure after guide piece breakage is difficult to keep, when causing gas generator to start, guide piece lost efficacy, and have impact on the homogenous charge effect of air bag, gas replenishment process is no longer reliable.
Utility model content
For above technical matters, the utility model provides a kind of Novel automobile safety airbag, airflow guiding device in this air bag can divide in the mode preset when being subject to too high gas shock power, and after division, its directional tagging also can be maintained, and guarantees that airbag inflated is reliable.
The technical scheme that the utility model adopts for its technical matters of solution is:
A kind of inflation failure-free safe automobile air bag, comprise gasbag, gas generator and air-flow guiding bag, air-flow guiding bag is located in gasbag, gas generator to be located in gasbag and by air-flow guiding bag parcel, described air-flow guiding bag is that flexible fabric is made, and the sack edge of air-flow guiding bag is sutured on the inwall of gasbag, and the bag bottom of air-flow guiding bag is provided with breach, breach is connected with capping by lacerable suture, described air-flow guiding bag and capping are densely covered with vent.
As preferred embodiment, the density of described capping upper vent is greater than the density of described air-flow guiding bag upper vent.
The beneficial effects of the utility model are: air-flow guide frame structure under normal airflow is impacted of air-flow guiding bag of the present utility model and capping composition can keep complete, the suture that capping and air-flow lead between bag when being subject to excess pressure gas shock can be torn, capping can entirety come off, form the king-sized pore air feed of an area to flow through, after capping comes off, the structure integrity of air-flow guiding bag is unaffected, can continue normal work.As can be seen from above process, air-flow guide frame of the present utility model can divide in the mode preset when being subject to too high gas shock power, and after division, its directional tagging also can be maintained, and guarantees that airbag inflated is reliable.
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 guiding bag, 4-capping, 5-vent.
Detailed description of the invention
With reference to Fig. 1, the disclosed a kind of inflation failure-free safe automobile air bag of the utility model forms primarily of gasbag 1, gas generator 2 and air-flow guiding bag 3.Air-flow guiding bag 3 is located in gasbag 1, and gas generator 2 to be located in gasbag 1 and to be wrapped up by air-flow guiding bag 3.Air-flow guiding bag 3 is made for flexible fabric, the sack edge of air-flow guiding bag 3 is sutured on the inwall of gasbag 1, the bag bottom of air-flow guiding bag 3 is provided with breach, and breach is connected with capping 4 by lacerable suture, and air-flow guiding bag 3 and capping 4 are densely covered with vent 5.
Air-flow guiding bag 3 and capping 4 form air-flow guide frame of the present utility model, and after installing assembling, the air extractor duct of gas generator 2 facing to i.e. capping 4 place ejection at the bottom of the bag of air-flow guiding bag 3, thus can produce gas shock to this place.Impact downstream guide frame in normal airflow and can keep complete, now fraction can be passed in gasbag 1 from the vent 5 capping 4, and other positions that remainder is then distributed to air-flow guiding bag 3 are inflated to gasbag 1 by corresponding vent 5.This guide functions 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.
The suture that capping 4 and air-flow lead between bag 3 when being subject to excess pressure gas shock can be torn, capping 4 can entirety come off, form the king-sized pore air feed of an area to flow through, after capping 4 comes off, the structure integrity of air-flow guiding bag 3 is unaffected, can continue normal work.
During concrete enforcement, the density of capping 4 upper vent 5 can be set as the density being greater than air-flow guiding bag 3 upper vent 5, makes capping 4 can flow out more gas.
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 (2)
1. an inflation failure-free safe automobile air bag, comprise gasbag, gas generator and air-flow guiding bag, air-flow guiding bag is located in gasbag, gas generator to be located in gasbag and by air-flow guiding bag parcel, it is characterized in that: described air-flow guiding bag is that flexible fabric is made, the sack edge of air-flow guiding bag is sutured on the inwall of gasbag, the bag bottom of air-flow guiding bag is provided with breach, breach is connected with capping by lacerable suture, described air-flow guiding bag and capping are densely covered with vent.
