Embodiment 1

[0028] The airbag device disclosed in this embodiment can simultaneously protect the driver and the front passenger from the front. The airbag device is embedded in the front end of the roof, and has a gas generator (not shown in the figure) and an airbag detail 100 .

[0029] see figure 2 and image 3 , the air bag assembly is folded in a reciprocating folding manner ( figure 2 ) or folded in a winding manner ( image 3 ) is placed at the front end of the canopy, and can be deployed downward after inflating, and placed in front of the driver and front passengers to simultaneously protect the driver and front passengers (see Figure 4 and Figure 5 ). There is only one gas generator, which can be placed on the roof, A-pillar, or other appropriate locations. When installed on the roof, the airbag unit frees up space for the steering wheel and instrument panel.

[0030] see figure 1 , the airbag assembly 100 has an inflator 110, the inflator is sewn from the first airba...

Embodiment 2

[0034] see Figure 6 , 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

[0036] 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 connected together, wherein one inflatable 110 is used to protect the driver from the front, and the other inflatable 120 is used to protect the front from the front. Rows of occupants; the air bag assembly 100a of each row in the back is embedded in the roof, and is arranged on the front side of each row of occupants, and has inflatables 110a, 120a, 130a corresponding to the number of occupants in each row, for simultaneous Protect every rear occupant from the front.

Abstract

The invention discloses a safety air bag device, which is embedded into the top of a vehicle and is provided with an air generator and an air bag component, wherein the air bag component is provided with an air inlet and one or more air filled objects; the air inlet is connected with the air generator and is communicated with each air filled object through an independent air inlet channel; and the independent air inlet channels are communicated with one another. The invention innovatively provides a concept for protecting a driver and passengers in a front row and every passenger in a back row from a front face by using the safety air bag device, so that the function of protecting each passenger of the conventional digital audio broadcasting (DAB) and primary application block (PAB) are realized, or / and passengers in the back row are better protected. When the device is compared with the conventional air bag, one or more groups of air bag parts are reduced and a module structure is simplified and integrated, so that weight is reduced, cost is lowered and the utilization spaces of a steering wheel and an instrument desk are expanded.

Description

technical field [0001] The invention relates to the technical field of automobile safety airbags, in particular to an airbag device which simultaneously protects the driver and front row passengers from the front, or simultaneously protects the rear row passengers from the front. Background technique [0002] With the improvement of automobile safety performance requirements, airbags to protect the driver and front-seat passengers have become standard configurations. For example, the airbag DAB used to protect the driver is installed in the steering wheel, and the airbag PAB used to protect the occupant is installed on the instrument panel. Because the driver's side and the passenger's side used on the current motor vehicle are all single air bag structures, each adopts a separate gas generator to inflate. Generally speaking, the airbags on the driver's side and the passenger's side generally cover more complex parts, such as: door cover, airbag fixing container, generator,...
