Abstract
The utility model relates to a safety belt of an anti-collision air bag for an automobile, comprising an air storage tank, a firing device, a guy cable mechanism, an air bag belt and a fixing seat. When the automobile collides, a braiding belt draws a pull ring in the firing device by using the impact gravity of a human body, a safety core is damaged, and two cams are driven to force a valve to open. Compressed air (CO<2>) expands rapidly and fills the air bag belt, the air bag belt is unfolded at the front part of the human body, and the purposes of cushioning and protecting are achieved. The utility model completely is a mechanical method, has the advantages of rapid triggering, simple structure, high reliability and low cost, can be used repeatedly for multiple times, and the reaction speed is 0.03 second. The utility model adopts the double safety of the air pressure and the safety core, adopts a speed overriding clutch mechanism, can not generate false actions under the conditions of the normal vibration and the normal action of the human body, and only acts under the condition of generating suddenly accidents.
Description
The utility model relates to drives and occupant's safety guard.
Vehicle is under steam in order to alleviate the human casualty accident that causes with crash-avoidance, prior art is to use the safety belt fixing human, safety has been improved a step, and tired bending turns forward but violent seismic inertia people knows from experience nature, also can cause the generation of casualty accident.Another kind of measure is that anti-collision air bag is installed, and is installed in the middle of the bearing circle front windshield below respectively, the place ahead, seat top, its shortcoming are to utilize the electric induction explosive blasting to produce gas, and child be wound the extruding death incident often generation, its complex structure involves great expense, and using once is subscription rate.
The utility model purpose is to provide a kind of prior art deficiency that remedies, simple in structure, volume is little, in light weight, cheap, easy for installation, collecting two kinds of functions is that one can be inflated nonexpondable anti-collision air bag safety belt again repeatedly.
The utility model is achieved in that air bottle and percussion lock sealing is fastening, is assembled on the permanent seat together, is fixed on seat one side air bag band and air inlet and chews percussion lock avris air extractor duct and seal fastening.The drag-line mechanism other fixed seating of braid two end portions opposite side top and below.The middle plug of braid is extracted belt body out and is protected human body during use, and plug inserts percussion lock top socket, simultaneously the air bag band is covered in braid, and hasp of its head fastens braid.Meet the preshoot of severe impact human body weight, utilize the braid pulling force to drive percussion lock and force cam rotation, back down spool, the air bag band expands in 0.03 second and is deployed in human body the place ahead, reaches the buffering purpose, forms a kind of anti-collision air bag safety belt.
Accompanying drawing 1 is an overall structure scheme drawing of the present utility model;
Accompanying drawing 2 is a percussion lock structural representation of the present utility model;
Accompanying drawing 3 is the structural representation after the utility model drag-line mechanism goes to cover.
Below in conjunction with accompanying drawing the utility model is described in detail again.
The utility model figure is lined with packing seal by air bottle (1) and percussion lock (2) faying face to use the Luo line fastening again, percussion lock avris air extractor duct (9) is chewed faying face lining packing seal with air bag band (4) air inlet and is used the Luo line fastening again, and the above-mentioned permanent seat (5) that all is combined in is fixed in seat one side.Its braid (15) two end portions of drag-line mechanism (3) are not fixed in seat opposite side two places up and down.Plug during use (16) is inserted mutually with socket (14), and air bag band (4) covers and is pasted on the braid (15).
Percussion lock (2) is made up of spring (6), valve body (7), spool (8), air extractor duct (9), draw ring (10), cam (11), hollow pivot pin (12), pull bar (13), socket (14) etc.Wherein (8) two faces of valve body (7) and spool are that sealed type contacts, and cam (11) utilizes moving its centre hole of joining of hollow pivot pin (12) the insurance core to be housed and to be hidden in draw ring (10) inboard with valve body (7), and pull bar (13) links to each other with socket (14).
Drag-line mechanism (3) is made up of braid (15), plug (16), spring (17), roller (18), housing (19), tape feed roller (20), clockwork spring (21) etc.Wherein roller (18) contacts with braid (15), spring (17), (19) faces of housing respectively, braid (15) one statures be fixed in (21) two of tape feed rollers (20), clockwork spring respectively with tape feed roller (20) internal diameter, housing (19) center fixation.
