Abstract
The utility model discloses a car air bag through reinforced material design, including air -bags and gas generator, air -bags and gas generator intercommunication, air -bags adopt the elastic plastic material to make, and the surface on air -bags top is equipped with the enhancement piece, strengthen the periphery of piece and pass through strengthening band fixed connection in air -bags's bottom, strengthen piece and strengthening band and are fixed in air -bags on the surface through the mode that bonds. The utility model discloses can stereotype to the gasbag after expanding, the rigidity distribution among the gasbag deployment process is more even to increase air bag in aerifing deployment process with passenger's contact action area, reduce air bag and to passenger's impact, promote the safety protection effect of the positive air bag of driver to the passenger, the utility model discloses a reinforced material still has the effect of strengthening the gasbag bulk strength, the mode that enhancement piece and strengthening band adoption bonded is fixed and has also been ensured the simply convenient of manufacturing process.
Description
Technical field
The utility model relates to a kind of safe automobile air bag, is specifically related to a kind of safe automobile air bag of being shaped by reinforcement material.
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.
When gas generator starts, the gas produced can be concentrated from air extractor duct ejection, and the gas of ejection can first to the central aeration of air bag, and gas expands to periphery again and the periphery of air bag is launched.Therefore generally, there will be the phenomenon that air bag top is heaved completely, periphery does not also launch after airbag actuation, the air bag under this state can produce secondary damage to the head of chaufeur or passenger and neck.Current part air bag carries out moulding, this mode complex structure by the shape after the mode of design various piece volume, thickness struts air bag, makes difficulty.
Utility model content
For above technical matters, the utility model provides a kind of Novel automobile safety airbag, and it can control effectively to the shape after air bag struts, and structure is simple, easy to make.
The technical scheme that the utility model adopts for its technical matters of solution is:
A kind of safe automobile air bag of being shaped by reinforcement material, comprise gasbag and gas generator, gasbag is communicated with gas generator, gasbag adopts elastic plastic material to make, the outside face on described gasbag top is provided with reinforced sheet, the periphery of reinforced sheet is fixedly connected on the bottom of gasbag by some well-distributed stiffening bands, the another kind of elastic plastic material that described reinforced sheet and stiffening band adopt hardness to be greater than gasbag is made, and reinforced sheet and stiffening band are fixed on gasbag on the surface by bonding mode.
As preferred embodiment, the surface of described reinforced sheet and stiffening band is bonded with nonwoven fabric layer.
The beneficial effects of the utility model are: the reinforced sheet set by the utility model and stiffening band hardness ratio gasbag large, when gasbag inflation, reinforced sheet and stiffening band can limit the degrees of expansion of relevant position, particularly, the junction of air bag top and top and bottom is launched degree and can be controlled, gasbag is no longer preferential to launch from top, but evenly launch to surrounding, realize air bag sizing, this structure makes the Stiffness Distribution in airbag deployment process more even, thus increase safety air bag in inflating expanded process with the contact action area of occupant, reduce safety air bag to the impact of occupant, promote chaufeur frontal airbag to the safety protective effect of occupant, reinforcement material of the present utility model also has the effect strengthening air bag bulk strength, reinforced sheet and stiffening band adopt bonding mode to be fixed and also ensure that the simple and convenient of manufacturing process.
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-reinforced sheet, 4-stiffening band.
Detailed description of the invention
With reference to Fig. 1, disclosed in the utility model, a kind of safe automobile air bag of being shaped by reinforcement material mainly comprises gasbag 1 and gas generator 2, and gasbag 1 is communicated with gas generator 2, and gasbag 1 adopts elastic plastic material to make.The gas that gas generator 2 produces when starting enters in gasbag 1 and orders about gasbag 1 and expand.
After expanding to make gasbag 1, shape can realize sizing, and the utility model is provided with reinforced sheet 3 at the outside face on gasbag 1 top, and the periphery of reinforced sheet 3 is fixedly connected on the bottom of gasbag 1 by some well-distributed stiffening bands 4.As shown in the figure, reinforced sheet 3 is the schistose texture that an area is larger, and stiffening band 4 is list structure.The another kind of elastic plastic material that reinforced sheet 3 and stiffening band 4 adopt hardness to be greater than gasbag 1 is made, and reinforced sheet 3 and stiffening band 4 are fixed on gasbag 1 on the surface by bonding mode.One of them reason that gasbag 1, reinforced sheet 3 and stiffening band 4 adopt elastic plastic material to make be make mutually between that viscose glue can be adopted to carry out is bonding, guarantee flexibly easy to make.
Reinforced sheet 3 and stiffening band 4 hardness ratio gasbag 1 large, when gasbag 1 inflation, reinforced sheet 3 and stiffening band 4 can limit the degrees of expansion of relevant position, particularly, the junction of air bag top and top and bottom is launched degree and can be controlled, gasbag 1 is no longer preferential to launch from top, but evenly launch to surrounding, realize air bag sizing, this structure makes the Stiffness Distribution in airbag deployment process more even, thus increase safety air bag in inflating expanded process with the contact action area of occupant, reduce safety air bag to the impact of occupant, promote chaufeur frontal airbag to the safety protective effect of occupant.
During embody rule, in order to make the intensity of reinforced sheet 3 and stiffening band 4 more strengthen, the surface of reinforced sheet 3 and stiffening band 4 can be bonded with nonwoven fabric layer further.
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. a safe automobile air bag of being shaped by reinforcement material, comprise gasbag and gas generator, gasbag is communicated with gas generator, gasbag adopts elastic plastic material to make, it is characterized in that: the outside face on described gasbag top is provided with reinforced sheet, the periphery of reinforced sheet is fixedly connected on the bottom of gasbag by some well-distributed stiffening bands, the another kind of elastic plastic material that described reinforced sheet and stiffening band adopt hardness to be greater than gasbag is made, and reinforced sheet and stiffening band are fixed on gasbag on the surface by bonding mode.
