Abstract
A kind ofly to use on a vehicle; the Double-cavity safety air bag device of driver and crew's safety can be protected when meeting with a street accident; be made up of impact microphone, gas filled device, two-chamber safety air bag and auxiliary device, it is characterized in that: two-chamber safety air bag is made up of main chamber and secondary chamber.Impact microphone is connected with gas filled device, and gas filled device is connected with main chamber, has air bag interlayer between main chamber and secondary chamber, and air bag interlayer has multiple through hole.When vehicle is subject to hard hit, impact microphone sends signal control gas filled device to main chamber fast aeration, and the gas in main chamber is inflated secondary chamber by the through hole on air bag interlayer.In air bag expansion phase, the pressure in secondary chamber is lower than the pressure in main chamber, and driver and crew are first met in the secondary chamber that air pressure is low, forms a soft infrabar buffer zone, alleviate the impulsive force of air bag to human body between driver and crew and the high main chamber of air pressure.
Description
Art
The present invention relates to and a kind ofly to use on a vehicle, the safety air bag safety device for motor vehicle of driver and crew's safety can be protected when meeting with a street accident, being especially used on automobile.
Background technology
At present, known air bag system for vehicle is linked in sequence by impact microphone, gas filled device, safety air bag and auxiliary device and forms.When vehicle is subject to hard hit; impact microphone sends signal; the gas filled device of safety air bag is to safety air bag fast aeration; and at aerification in a flash; a neonychium is formed to human body; when driver and crew are due to effect of inertia impact forward or to side impact, safety air bag plays the effect of buffering shock-absorbing, the personal safety of protection driver and crew.But the moment collided, the health of passenger will lean forward, and now air bag is just in expansion phase, and driver or passenger may run into air bag.Air bag kinetic energy in expansion phase is large, similarly is the rigid body in a motion, can injures and the driver of its collision or passenger.The power reducing air inflator system makes air bag speed of expansion slow down; the driver that health can be protected short and passenger; if but automobile collides when high-speed cruising; the driver of all statures and passenger lean forward all at a high speed; because air bag fails to expand into enough large; driver or passenger collide on bearing circle, gauge panel or Windshield possibly, thus come to harm, and the slow air bag of speed of expansion can not protect driver or passenger effectively.China Patent Publication No. CN1205956A; publication date on January 27th, 1999; invention and created name is composite high-pressure and low-pressure safety air bag device; that application discloses the device that a kind of surface portion contacted with driver and crew after former airbag aeration installs an additional balloon additional; when being collided, inflation pump is directly to former airbag aeration, and inflation pump is inflated additional balloon by a decompression layer simultaneously; additional balloon forms a buffer zone between Primordial Qi capsule and human body, to protect driver and crew.Weak point is for adding additional balloon and decompression layer, and complex structure, makes difficulty, and the pressure of additional balloon is not easy to control.
Summary of the invention
Under the prerequisite not reducing air bag speed of expansion, in order to realize reducing impulsive force to people when air bag expands, and air bag device structure simple, be easy to manufacture.The invention provides a kind of Double-cavity safety air bag device; even if do not reducing speed of expansion; when not reducing bag volume; this safety air bag also can reduce the impulsive force of air bag to human body greatly when air bag expands; improve its security protection to driver and crew, and simple, the secondary cavity pressure of structure easily controls.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Double-cavity safety air bag device, is made up of impact microphone, gas filled device, two-chamber safety air bag and auxiliary device.Two-chamber safety air bag is made up of main chamber and secondary chamber.There is air bag interlayer between the main chamber of two-chamber safety air bag and secondary chamber, air bag interlayer has multiple through hole.When vehicle is subject to hard hit, impact microphone sends signal control gas filled device to main chamber fast aeration, and the gas in main chamber is inflated secondary chamber by the through hole on air bag interlayer.In air bag expansion phase, the pressure in secondary chamber is lower than the pressure in main chamber, and driver and crew are first met in the secondary chamber that air pressure is low, forms a soft infrabar buffer zone, alleviate impulsive force between driver and crew and the high main chamber of air pressure.The quantity of through hole on adjustment air bag interlayer and the height of the size in aperture and adjustable secondary chamber air pressure.
The beneficial effect of patent of the present invention is: no matter vehicle is for fast state or lower-speed state; when vehicle is subject to clashing into; two-chamber safety air bag effectively can reduce the impact to driver and crew, and protection chaufeur or passenger can not come to harm, and simple, the secondary cavity pressure of structure easily controls.

Detailed description of the invention
Structure and the principle of work of Double-cavity safety air bag device are described for bearing circle safety air bag below.
In the drawings, two-chamber safety air bag (3) is made up of main chamber (5) and secondary chamber (9), main chamber (5) is connected with gas filled device (2), gas filled device (2) is connected with impact microphone (1), contact with human body after secondary chamber (9) inflation, have air bag interlayer (7) between main chamber (5) and secondary chamber (9), air bag interlayer (7) has multiple through hole (8).
Fig. 1, two-chamber safety air bag (3) overlays in bearing circle (4).
Fig. 2, gas filled device (2) is to main chamber (5) inflation, and the gas in main chamber (5) is inflated secondary chamber (9) by through hole (8).In gas replenishment process, the air pressure in secondary chamber (9) is lower than the air pressure in main chamber (5).
Fig. 3, when people's bench over and two-chamber safety air bag (3) collide, hypobaric secondary chamber (9) forms a soft buffer zone between human body and anticyclonic main chamber (5), human body first bumps against with hypobaric secondary chamber (9), alleviates impulsive force.
Regulate the height of the pressure in the number of through hole and the size in aperture and adjustable secondary chamber on air bag interlayer.
Claims (1)
