Abstract
The present invention discloses tube type air bag which aims to provide the tube type air bag which has the advantage of few air consumption and can be quickly and effectively inflated and expanded according to predeterminate positions. The present invention is characterized in that the present invention is a truss which is composed of hollow air tubes, one or more than one air filling openings are arranged on the truss, and air pressure diaphragms are arranged on the connecting points of the longitudinal air tubes and the transversal air tubes of each layer of the truss.
Description
Technical field:
The present invention relates to a kind of air bag, be specifically related to the structural development of air bag, be specially adapted to vehicle driver and crew are protected.
Background technology:
At present, air bag system is more and more used in auto trade as a kind of restraint device of protection driver and crew head.The air cushion that present safety air bag all adopts the airbag inflation to form a softness plays buffering energy-absorbing function, to reduce the injury to driver and crew.Crashing, when being necessary to start safety air bag, producing a large amount of gases by gas generator airbag is inflated, making its protective cover that expands into a softness, buffering is to the collision impact of human body.In order to obtain the better protect effect, the volume of airbag generally can not be too little, and for the airbag of driver side, its volume is generally 30～60L, and the airbag of driver and crew's side is then wanted about 60～150L.Conventional balloon generally all is first inflation, and air bag is gone out after expansion and launched, and like this, when inflation, make rapid aerification of airbag and expansion fully, and not only required gas flow is big, and the direction that airbag launches is not easy control.And because the aeration speed of air bag is very fast, the huge impulsive force forward that produces when air bag begins to expand probably damages human body, especially the human body of offing normal is damaged.
Summary of the invention:
Technical matters to be solved by this invention is to overcome the defective that above-mentioned prior art exists, provide a kind of gas consumption few, can be fast and effeciently by the inflating expanded tubular type air bag in preset bearing.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of tubular type air bag, it is characterized in that it is a truss of being made up of hollow tracheae, described truss is provided with one or more than one inflation inlet, is provided with the air pressure diaphragm in every layer of vertical tracheae of described truss and horizontal tracheae junction.
As a further improvement on the present invention, described truss is to be formed by connecting by two layers or more horizontal tracheae and vertical tracheae of being supported between per two layers of horizontal tracheae.
Described truss can be square or polygonal truss.Described square truss be by be upper and lower layer that matrix pattern arranges laterally tracheae and be supported in upper and lower layer laterally the vertically arranged vertical tracheae that is between the tracheae be formed by connecting, inflation inlet is offered in the bottom of the horizontal tracheae of lower floor.Described vertical tracheae can be five, a center that is arranged at matrix pattern, all the other four four jiaos of being symmetrically arranged in matrix pattern.Described vertical tracheae can be more than five, and symmetry is distributed in upper and lower layer laterally between the tracheae.
Described truss also can be circle or oval truss.Described circle or oval truss are circular or oval laterally tracheae and be supported in and be vertically arranged vertical tracheae between per two layers and be formed by connecting by upper, middle and lower-ranking, and inflation inlet is offered in the bottom of the horizontal tracheae of lower floor.Described vertical tracheae is provided with more than three or three for every layer, be distributed in, the horizontal tracheae in middle level and in, between the horizontal tracheae of lower floor.
Compared with prior art, air bag of the present invention adopts the tubular type truss structure, inflates used tolerance than airbag and significantly reduces, and can adopt less gas to reach the inflation effect of common airbag, and can launch by predetermined direction.The present invention is arranged in the vehicle, can reduce driver and crew's damage that collision, secondary collision cause effectively or avoid secondary collision, and when having significantly reduced airbag inflation to the injury of human body, improve the protectiveness of air bag device.

The specific embodiment:
Shown in Fig. 1,2,3,6, tubular type air bag of the present invention, it is a truss 1 of being made up of hollow tracheae, truss 1 is provided with one or more inflation inlet 2, every layer of vertical tracheae at described truss is provided with air pressure diaphragm 3 with horizontal tracheae junction, can bear gaseous tension in various degree, the inflation direction of control truss 1.Truss 1 can be formed by connecting by two layers or more horizontal tracheae and the vertical tracheae that is supported between per two layers of horizontal tracheae, can be square, polygon, circle or oval.
Fig. 1,3,4,5 shows the tubular type air bag of square truss structure, be by be upper and lower layer that matrix pattern arranges laterally tracheae 12,13 and be supported in upper and lower layer laterally the vertically arranged vertical tracheae 11 that is between the tracheae 12,13 be formed by connecting, vertically tracheae 11 is five, a center that is arranged at matrix pattern, all the other four four jiaos of being symmetrically arranged in matrix pattern.Vertically tracheae 11 also can be set to more than five, and symmetry is distributed in upper and lower layer laterally between the tracheae.Inflation inlet 2 is arranged at lower floor horizontal tracheae 13 bottoms.
Fig. 2,6,7,8 shows another embodiment of the present invention, is the tubular type air bag of circular truss structure, is by the circular laterally tracheae 12,14,13 of upper, middle and lower-ranking and is supported in and is vertically arranged vertical tracheae 11 between per two layers and is formed by connecting; Vertically tracheae 11 every layer can be provided with more than three or three, be distributed in, the horizontal tracheae 12,14 in middle level and in, between the horizontal tracheae 14,13 of lower floor, four of this example employings.Inflation inlet 2 is arranged at lower floor horizontal tracheae 13 bottoms.Present embodiment has better folding property at mode of operation not.
Principle of work of the present invention is: inflation inlet 2 of the present invention joins with the air extractor duct of gas generator, the gas that gas generator produces is via the inflation inlet 2 that is positioned at truss 1 bottom, at first the horizontal tracheae 13 of truss 1 bottom is inflated, when pressure surpasses the bearing pressure of air pressure diaphragm 3, gas breaks through other tracheae inflations of 3 pairs of truss 1 of air pressure diaphragm, finishes until whole truss 1 inflation.The present invention is arranged in the vehicle, when bumping, can effectively protect driver and crew.
The present invention also can be used as the air bag of other purposes.
The present invention also can set out pore on truss 1 top cross tracheae 12, can put on the air to connected other gas filled devices, is combined to form an air bag with high-low pressure combined type.Be used for the protection of driver and crew in the vehicle; connect an airbag again at truss 1 top; can reach the inflation effect of common safety air bag with less gas; and make truss and airbag have two kinds of different rigidity; make and have lower rigidity with the contacted buffer air bag of human body; the impulsive force that during with airbag inflation human body is produced is become the shock absorbing of present low-pressure gas by the moment impact of conventional balloon inner high voltage gas; to the injury of human body, improve the defencive function of air bag device when having significantly reduced airbag inflation.
