    Car airbag cushion device
    The present invention relates to an automobile airbag cushioning device, and more particularly, a vehicle has a crash accident and explosives are exploded and gas is supplied to the cushion from an inflator, but is sequentially supplied and expanded to the body of a driver or a passenger. The present invention relates to an automobile airbag cushion device that does not overdo it.
    In general, the airbag of the car serves to greatly reduce the injury of the human body by acting as a collision to the vehicle to alleviate the impact of a solid object in the room to the human body, such as the driver, and swells quickly during the collision of the vehicle By rising cushioning device.
    The vehicle airbag system comprises a sensor for detecting a collision state of the vehicle, a control module for receiving the information of the sensor and determining the operation of the airbag, and an airbag module for operating the airbag by receiving the signal of the control module. The airbag module has a built-in cushion device connected to the inflator installed in the center of the steering wheel and serves to fill the air.
    1 is a view schematically showing a vehicle airbag cushion device according to the prior art.
    Although the airbag cushion device 10 has been mentioned above, the airbag cushion device 10 is inflated by an inflator applied from an inflator (not shown) to mitigate an impact applied to a driver or the like.
    The cushion device 10 is composed of two chambers 12 and 14, one of which is connected to the inflator to form a gas inlet 16 to which an inflation gas is applied.
    Each of the chambers 12 and 14 forms a diaphragm 18 and vent holes 20 and 22 are formed at left and right sides of the diaphragm 18 to vent the gas transmitted from the gas inlet 16. Dispensing is through holes 20 and 22.
    However, in the conventional cushion device, the gas supplied from the inflator operated by the collision of the vehicle is transferred to the diaphragm 18 as it is through the gas inlet 16 and the second through the vent holes 20 and 22. Since the gas pressure is supplied to the chamber 14, the gas pressure supplied by the inflator is directly transmitted to the body of the driver or the like to cause injury.
    An object of the present invention is to solve the above problems, the vehicle is crashed due to the gunpowder is exploded by the gas supplied to the cushion from the inflator (inflator) but is supplied sequentially to expand the driver or passengers body An object of the present invention is to provide a vehicle airbag cushioning device that does not provide a vehicle.
    The present invention to achieve the above object, the first chamber is connected to the inflator of the vehicle airbag system; A pocket formed at a gas inlet of the first chamber to form a diaphragm having a vent hole in the front thereof and formed by opening an upper diaphragm; Bubbles concavely formed in one direction in a direction in which the diaphragm of the pocket is opened; And a second chamber formed by dividing the first chamber connected from the bubble and the diaphragm forming a vent hole.
    1 is a view schematically showing a vehicle airbag cushion device according to the prior art,
    Figure 2 schematically shows a vehicle airbag cushion device according to an embodiment of the present invention.

    Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, in which the technical constitution and operational effects as an exemplary embodiment can effectively achieve the object of the present invention.
    2 is a view schematically showing a vehicle airbag cushion device according to an embodiment of the present invention.
    The airbag cushion device 100 of the vehicle 100 includes a first chamber 102 and a second chamber 104 as in the related art, and the first chamber 102 and the second chamber 104 are vent holes 103 and 103 '. It is divided into a diaphragm 105 formed.
    However, the first chamber 102 does not directly introduce the gas exploded from the inflator into the second chamber 104.
    In other words, the first chamber 102 forms a pocket 114 at the inlet 110 to achieve primary gas circulation, and forms a bubble 116 to achieve secondary gas circulation.
    The pocket 114 forms a diaphragm 120 to be distinguished from other parts of the first chamber 102, but the diaphragm 120 forms a vent hole 122, and is opened in an upward direction and in one direction. A gas flow diverting point 124 for switching the gas flow is formed.
    The bubble 116 is formed to be concave in the direction toward which the gas flow turning point 124 that the diaphragm 120 rotates forms a gas inlet inside the diaphragm 120, and the opposite side forms a gas outlet.
    Therefore, the gas flow is not discharged directly into the first chamber 102 due to the diaphragm 120, the gas entering the pocket 114 in the inlet 110, a part of the first chamber through the vent hole 122 ( 102 is discharged into the first chamber 102 through the bubble 116 to the opposite outlet through the gas flow transition point 124 of the diaphragm.
    The gas flowing out into the first chamber 102 circulates through the first chamber 102 and flows out into the second chamber 104 through the vent holes 103 and 103 ′ of the diaphragm 105 to expand.
    According to a preferred embodiment of the present invention, when a collision accident occurs in the vehicle, the sensor detects this and explodes the gunpowder, and the inflator discharges the compressed gas into the first chamber. The first chamber is filled with gas that enters through the vent hole in the diaphragm of the pocket or with gas that circulates the bubble.
    As described above, the vehicle airbag cushioning device of the present invention, the vehicle is crashed due to an accident, gunpowder is exploded and gas is supplied to the cushion from the inflator, but is supplied sequentially to inflate the body of the driver or passengers It is effective to avoid giving.
