Abstract
The invention discloses a buffer type automobile airbag which comprises an airbag body, a gas generator and an airflow guide bag, wherein the airflow guide bag is arranged in the airbag body, and the gas generator is arranged in the airbag body and wrapped by the airflow guide bag; the airflow guide bag is formed by splicing multiple woven cloth blocks, and the adjacent woven cloth blocks are closely connected through tearable suture threads; the edge of the airflow guide bag is sutured on the inner wall of the airbag body through the tearable suture threads, and air holes are not formed in the airflow guide bag. The working process of the buffer type automobile airbag is as follows: gas is diffused from a point into a small body and then diffused from the small body into a big body. The process has a good buffer effect on the pressure of gas, the gas is more uniform when being diffused from the airflow guide bag to the airbag body, and the protection effect of the airbag is good.
Description
Technical field
The present invention relates to a kind of safe automobile air bag, be specifically related to a kind of buffer type 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; gasbag 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.
Gas generator can produce a large amount of gas when starting at short notice, and the gas produced can be concentrated from the actively little air extractor duct ejection of an individuality, and the gas of ejection is diffused in the great gasbag of volume again.This gas is extremely rambunctious from point to the diffusion process of body, and the phenomenon that air bag inflation pressure generally can be caused uneven occurs.Current mode arranges airflow guiding device to carry out the guiding of gas, and these guide piecees realize work by vent.The guide frame of this passage guiding does not solve the uneven problem of inflation pressure completely.
Summary of the invention
For above technical matters, the invention provides a kind of Novel automobile safety airbag, it serves good buffer action to the high pressure gas that gas generator produces, and guarantees that air bag inflation pressure is even.
The technical scheme that the present invention adopts for its technical matters of solution is:
A kind of buffer type automobile safety 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 spliced by polylith block of weaving cotton cloth, adjacent weaves cotton cloth by lacerable suture compact siro spinning technology between block, and the edge of air-flow guiding bag on the inwall of gasbag, air-flow guiding bag is not provided with pore by not lacerable suture.
As preferred embodiment, each block of weaving cotton cloth is provided with the locking cloth be connected on gasbag inwall.
The invention has the beneficial effects as follows: when gas generator of the present invention starts, its gas produced is introduced in air-flow guiding bag, air-flow guiding bag is made to be filled up expansion, when pressure acquires a certain degree, the suture breaks of weaving cotton cloth between block of air-flow guiding bag, now air-flow guiding bag decomposes, and inner gas is diffused in gasbag again.Therefore the process of work of the present invention is that gas is diffused in corpusculum from point; be diffused into substantially from corpusculum again; this process can play good buffering to the pressure of gas, can be more even when gas is diffused into gasbag from air-flow guiding bag, guarantees that the protected effect of air bag is better.
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, and 3-air-flow guiding bag, 4-weaves cotton cloth block.
Detailed description of the invention
With reference to Fig. 1, a kind of buffer type automobile safety air bag disclosed by the invention 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.
The maximum feature of the present invention is, air-flow guiding bag 3 is spliced by polylith block 4 of weaving cotton cloth, adjacent weaves cotton cloth by lacerable suture compact siro spinning technology between block 4, and the edge of air-flow guiding bag 3 on the inwall of gasbag 1, air-flow guiding bag 3 is not provided with pore by not lacerable suture.Owing to not being provided with pore, therefore air-flow guiding bag 3 is a hermetically-sealed construction when initial.When gas generator 2 starts, gas can first be filled in air-flow guiding bag 3, can not enter in gasbag 1.When air-flow guiding bag 3 inflation to a certain extent time, the suture of weaving cotton cloth between block 4 of air-flow guiding bag 3 can rupture, and now air-flow guiding bag 3 entirety is decomposed, and air-flow is transferred in gasbag 1 from air-flow guiding bag 3.Above-mentioned whole process is that gas is diffused in corpusculum from point; be diffused into substantially from corpusculum again; this process can play good buffering to the pressure of gas, can be more even when gas is diffused into gasbag 1 from air-flow guiding bag 3, guarantees that the protected effect of air bag is better.
Block 4 of weaving cotton cloth after decomposing to prevent air-flow guiding bag 3 disperses to impact on gasbag 1 and causes gasbag 1 damaged, and each block 4 of weaving cotton cloth preferably can be provided with the locking cloth be connected on gasbag 1 inwall.Or as shown in the illustrated embodiment of fig. 1, each block 4 of weaving cotton cloth is set to petal-shaped structure, forms hemisphere after block 4 of weaving cotton cloth combines, the bottom of each block 4 of weaving cotton cloth can with gasbag 1 be closely connected avoid decomposing after disperse.
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.
Claims (2)
1. a buffer type automobile safety 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 spliced by polylith block of weaving cotton cloth, adjacent weaves cotton cloth by lacerable suture compact siro spinning technology between block, and the edge of air-flow guiding bag on the inwall of gasbag, air-flow guiding bag is not provided with pore by not lacerable suture.
