Embodiment Construction

[0022] Refer figure 1 with figure 2 The window 8 is defined by the remainder portion of the substantially the same window profile 9 relative to the cover 7, and the window profile 9 is hoisted over its entire length through the pre-cutting portion 10. The pre-cutting portion is typically formed in most of the thickness of the cover 7. Therefore, when the window 8 is completely separated from the remainder of the cover 7. The baffle 4 is defined by the baffle profile 5 relative to the transmit channel 3. For example, the baffle profile 5 is basically rectangular. On one side of the baffle 4, the baffle 4 is fixed to the remainder of the transmitting passage 3 through the hinge portion 6, more specifically Figure 4 It can be seen in it. On the remainder of the baffle profile 5, the pre-cutting portion separates the baffle 4 to the remainder of the transmitting passage 3. This is more specifically image 3 It can be seen in it. Therefore, during the expansion, the baffle 4 is perpendi...

Abstract

The invention provides an airbag system (1) comprising: a launch channel (3) comprising a baffle (4) and a hinge (6) between the baffle (4) and the rest of the launch channel (3) ); and a cover (7) comprising a window (8) defined by a window profile (9) weakened by a pre-cut portion (10); wherein the emission channel (3) is fastened to the cover (7 ) and the baffle (4) is positioned in cooperation with the window (8), and wherein the fastening of the emission channel (3) to the cover (7) is performed using friction welding, the system (1) also includes a protection device, the protection device The pre-cut (10) can be protected from excess material produced by the welding operation at the rib (14) closest to the pre-cut (10).

Description

Technical field [0001] The present invention relates to a safe airbag system. Such systems are conventionally used in a known manner for motor vehicles to enhance the safety of the ride. Background technique [0002] In known ways, such as Figure 1 to 2 As shown in the present, the airbag system includes an inflatable bag 2 that can be inflated using a gas generator including a firework device after detecting a collision. When the airbag 2 is inserted outside its housing, it forms a damping pad between the wall and the passenger. The air bag 2 is stored in the housing located behind the wall. The transmit channel 3 is at least partially surrounding the balloon 2 and guides the airbag 2 when the airbag 2 is expanded. The transmit channel 3 covers a visual outer surface that forms a wall and provides a cover 7 of its aesthetic finish. In order to allow the airbag 2 to pass through the wall, the cover 7 includes a window 8 defined by the window profile 9. In order to make the window...
