Abstract

The utility model discloses a safe air bag of an automobile. The safe air bag comprises an air bag body and a connection piece assembly arranged in the middle of the air bag body. The middle of the top of the connection piece assembly is provided with a circular air inlet, four installation holes are uniformly formed in the periphery of the air inlet, and a plurality of sealing pieces are uniformly distributed on the air inlet along the circumference of the air inlet. The sealing pieces are uniformly formed in the air inlet of the air bag body along the circumference of the air inlet and are bent towards the inside of the air bag body in installation, the problem that after a gas generator is lit, produced high-temperature gas leaks towards the bottom of the air bag is effectively avoided, safe and quick inflating of the safe air bag is guaranteed, and reliability of the safe air bag is improved.

Description

A kind of safe automobile air bag
Technical field
The utility model relates to a kind of safe automobile air bag, belongs to the automotive safety technical field.
Background technology
At present; safety air bag all is installed on many automobiles; when automobile crashes; when control system of safety air bag detects impulsive force above setting value; squib circuit in the safety air bag computer demand working inflation element; light the ignition media in the squib; flame point of ignition fire powder and gas generant; produce a large amount of gases, in the time in 0.03~0.04 second, be about to airbag and be full of, airbag is sharply expanded; break through inside of automotive decorative cover plate drum to chaufeur and occupant; make chaufeur and occupant's bodily protection on gassiness airbag, buffering is emitted the gas in the airbag again subsequently to chaufeur and occupant's impact.
Present safety air bag generally is divided into airbag and connecting strap assembly, and generally be to install and fix by four mounting holes around the circular admission port at connecting strap assembly middle part, connecting strap assembly around the admission port is four circular arc seal strips to the extension of the admission port center of circle, and the position of sealing sheet is relative with mounting hole; Gas generator is fixed on the airbag outside, and is close together with it.In use, because gas generator can produce a large amount of high temperature and high pressure gas after igniting, when inflating in from admission port to airbag, because airbag is subjected to bigger pulling force, make that the suffered pulling force in airbag side that is installed between flameproof enclosure and the gas generator is excessive, break away from the installation site, form a bigger gap.During inflation, bottom deflation phenomenon occurs, cause the airbag inflation not exclusively and can't rapid expanding, make the protective value of airbag descend, threaten the life security of passenger and chaufeur.
The utility model content
The purpose of this utility model is: a kind of safe automobile air bag is provided, because the poorly sealed bottom deflation phenomenon that occurs, causes airbag aeration incomplete and can't rapid expanding to solve the conventional security air bag, make the problem of protective value decline of safety air bag.
The technical solution of the utility model:
A kind of safe automobile air bag, it comprises airbag, is arranged in the connecting strap assembly at airbag middle part, described connecting strap assembly top middle portion offers circular admission port, evenly is furnished with four mounting holes around this admission port, and wherein: described admission port upper edge circumference evenly is provided with some seal strips.
Preferably, described seal strip is circular arc.
Preferably, described seal strip has eight.
The beneficial effects of the utility model are:
Compared with prior art; the safe automobile air bag that the utility model provides; in the airbag admission port, along circumference some seal strips are set evenly; during installation with seal strip to the airbag internal bend; when inflation; the high temperature that produces when utilizing the gas generator action; melt these seal strips; between flameproof enclosure and gas generator, form the seal ring of a fusing; the protection airbag is not pulled, and prevents that effectively gas generator from lighting the huge pulling force that the back produces airbag and causing airbag and flameproof enclosure to pull, and makes high-temperature gas pull the external leakage problem; guarantee the inflation fast and safely of safety air bag, promoted the protective value of safety air bag.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is admission port of the present utility model place enlarged drawing;
Fig. 4 is coupled condition scheme drawing of the present utility model;
Fig. 5 is dotted portion enlarged drawing among Fig. 4;
Among the figure: 1-airbag, 2-connecting strap assembly, 3-mounting hole, 4-admission port, 5-seal strip, 6-gas generator, 7-flameproof enclosure.
The specific embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is further described, but that desired protection domain is not limited to is described.
As shown in Figure 1, 2, the reliable safe automobile air bag that the utility model provides, it comprises airbag 1, is arranged in the connecting strap assembly 2 at airbag 1 middle part, described connecting strap assembly 2 top middle portion offer circular admission port 4, evenly be furnished with four mounting holes 3 around this admission port 4, wherein: described admission port 4 upper edge circumference evenly are provided with some seal strips 5, melt to seal when the high temperature by sealing sheet 5, prevent the bottom deflation problem of high-temperature gas.
As shown in Figure 3, described seal strip 5 is circular arc, also possesses strong sealing property when saving material, prevents the high-temperature gas problem that becomes flat from the bottom when action.
Described seal strip 5 has eight, and is adjacent nearer between each seal strip 5, further the lift-off seal performance.
Embodiment: shown in Fig. 4,5, when the safe automobile air bag that the utility model provides is installed, earlier that airbag 1 is folding, make itself and connecting strap assembly 2 near, when gas generator 6 is installed, seal strip 5 to airbag 1 internal bend, is being installed whole air-bag module by bolt and mounting hole 3 and fixed.In use; ignition device starts; the high-temperature gas that gas generator 6 produces is inflated in airbag 1 by admission port 4; high-temperature gas is with seal strip 5 partial meltings of bending; form the seal ring of a fusing between flameproof enclosure 7 and gas generator 6, protection airbag 1 is not pulled, and prevents that effectively gas generator 6 from lighting high-temperature gas that the back produces in the problem of the place of pulling leakage; guaranteed the expansion safely and fast of airbag 1, made it have normal protective value.
