Problems solved by technology

[0006] However, further studies have found that when there is no occupant on the passenger side of the airbag, after the airbag is opened, the inflatable on the driver's side is pressed by the driver's body, and the gas in it will rush into the inflatable on the passenger's side, causing The air volume of the inflatable on the driver's side decreases and the pressure drops, which cannot effectively protect the driver. However, the air volume in the inflatable on the passenger's side

Embodiment 1

[0034] The airbag device disclosed in this embodiment has a plurality of inflatables, which can simultaneously protect the driver and the front passenger from the front. Bag assembly 100 .

[0035] see figure 1 , the air bag assembly 100 has two inflatables 110, 120 and a gas distribution chamber 200, an air inlet 130 is arranged on the air bag assembly 100, the gas distribution chamber 200 communicates with the air inlet 130, and the air inlet 130 is directly connected to the gas generator, of course, it can also be connected to the gas generator through the gas guiding device. The whole air bag assembly sewing process can be like this: first adopt the first gas distribution chamber bag sheet (not shown in the figure) and the second gas distribution chamber bag sheet (not shown in the figure) to sew the gas distribution chamber 200 . All sewing is carried out on a flat surface, which is easy to operate, convenient to control, and simple in process. Then the gas distribution

Embodiment 2

[0041] see Figure 9 , the safety airbag device is embedded in the front side of each rear passenger in the roof, and the airbag assembly 100a has two or three inflatables, wherein each inflatable is used to protect each rear passenger from the front, said The volume ratio of each air bag is the same. All the other structures are with embodiment 1.

Embodiment 3

[0043] see Figure 7 , the airbag device is embedded in the roof, and the airbag components are arranged at intervals. The first vent bag assembly 100 is arranged at the front end of the roof, and has two inflatables 110, 120 and a gas distribution chamber 200 connected together, wherein one inflatable 110 is used to protect the driver from the front, and the other inflatable 120 Used to protect the front occupants from the front. The gas distribution chamber 200 is provided with two distribution outlet channels 210, 220, the distribution outlet channels 210, 220 are in a constricted state relative to the gas distribution chamber 200, the gas distribution channel 210 extends into the inflatable object 110 and connects with the inflatable object 110 is internally penetrated. The gas distribution channel 220 extends into the inflatable 120 and communicates with the inside of the inflatable 120 .

[0044] The air bag modules 100a of each row in the back are embedded in the roof,

Abstract

The invention discloses an air bag restraint device with a plurality of inflating matters, which is embedded on the top of a vehicle and is provided with an air generator and an air bag assembly, wherein the air bag assembly is provided with an air inlet and one or more inflating matters, the air inlet is connected with the air generation, the air bag assembly also comprises an air distribution chamber communicated with the air inlet, a plurality of distribution air outlet channels are arranged on the air distribution chamber, each distribution air outlet channel is in a necking state relative to the air distribution chamber, and the air distribution air outlet channels extend into the corresponding inflating matters and are communicated with the insides of the inflating matters. By using difference of internal and external pressures of the distribution air outlet channels, the distribution air outlet channels are opened and closed, and further the purpose of controlling the air quantity and the pressure inside each inflating matter in an air bag restraint device with the plurality of inflating matters is achieved to ensure that each inflating matter can play a better protection role, and the possibility of explosion of the inflating maters is fundamentally avoided.
