Embodiment 1

[0026] see figure 1 , a kind of air bag that is used for passenger side safety air bag, and it has the first air chamber 200 of motor vehicle instrument panel IP100 side and the second air chamber 300 of personnel side, the conduit part (not shown in the figure) One end of the pipe is sewn on the position of the air inlet hole 211 of the first air chamber 200, the other end of the conduit part is surrounded on the gas generator (not shown in the figure), and the first air chamber 200 is deployed on the side of the vehicle instrument panel IP100 , the second air chamber 300 is deployed on the side of the person, and the first air chamber 200 and the second air chamber 300 communicate with each other through the vent hole 400 . The two ends of the outer drawstring 500 are sewn together with the first air chamber 200 and the second air chamber 300 respectively, in the form of an outer drawstring to stabilize and limit the opening shape and position of the airbag. The second air ...

Embodiment 2

[0032] see Figure 4 and Figure 5 , This embodiment is suitable for installing on the motor vehicle dashboard IP100 whose angle between the vertical line 600 and the horizontal plane 700 of the motor vehicle dashboard IP100 (door cover mounting surface) is 70° Figure 5 It can be seen from the figure that the air inlet hole 211 on the first air chamber panel I 210 is located off-center of the first air chamber panel I 210 . All the other parts are the same as in Example 1.

Embodiment 3

[0034] see Figure 6 and Figure 7 , This embodiment is suitable for installing on the motor vehicle dashboard IP100 whose angle between the vertical line 600 and the horizontal plane 700 of the motor vehicle dashboard IP100 (door cover mounting surface) is 60° Figure 7 It can be seen from the figure that the air inlet hole 211 on the first air chamber panel I 210 is located in a position that is more (compared with Example 2) off the center of the first air chamber panel I 210. All the other parts are the same as in Example 1.

[0035] It can be concluded from the above embodiments that the air inlet hole 211 gradually deviates from the center of the first air chamber panel I 210 as the angle α between the vertical line 600 and the horizontal plane 700 of the vehicle instrument panel IP100 (door cover mounting surface) becomes smaller . see Figure 8 .

[0036] It can be concluded from the above examples that the larger the ratio of the diameter of the vent hole 400 to th...

Abstract

The invention discloses an air bag used for a copilot side safety air bag, which is provided with a first air chamber on the side of a body and a second air chamber on the side of personnel which are communicated through vent holes; the first air chamber is formed by sewing a first air chamber cut piece I and a first air chamber cut piece II, the first air chamber cut piece I is provided with air inlet holes, and the first air chamber cut piece II is provided with vent holes I; the second air chamber is formed by sewing a second air chamber cut piece I and a second air chamber cut piece II, the second air chamber cut piece I is provided with vent holes II, and the vent holes I and the vent holes II have the same size and are sewed together to form the vent holes; and the air inlet holes gradually deviate from the center of the first air chamber cut piece I along with lessening an included angle alpha between the vertical line of a door cover mounting plane and a horizontal plane. The air bag can be filled fully without needing air generator with large output power to achieve the same effect with a conventional large output generator large capacity air bag, and can effectively protect passengers when motor vehicles collide.

Description

Technical field: [0001] The present invention relates to an airbag used for protecting personnel when a person collides with an object such as a motor vehicle, in particular to an airbag with a plurality of air chambers arranged in a collision direction, so that the gas generator with low power can also The air bag can be sufficient and meet the protection performance requirements. Background technique: [0002] The single-cavity PAB airbag has a large design volume, and the sewing process is complicated. It needs to be used with a high-power gas generator, and it has poor durability when used in different cars. [0003] As an airbag in which a plurality of airbags are arranged in a row in the collision direction, JP-A-2001-334895 describes an airbag for pedestrian protection in which smaller inner airbags are arranged up and down along the front surface of a motor vehicle. The lower part in the outer airbag which inflates largely. Due to the small volume of the inner air ...
