Description

Structure for fixing curtain air bag The present invention relates to a curtain airbag fixing structure that improves the assembly of an airbag by improving the mounting structure of the airbag cushion. Under normal circumstances, the airbag cushion remains folded within the airbag housing; however, when a sensor detects a vehicle collision, gas is rapidly supplied to the cushion via an inflator to instantly deploy the cushion, thereby protecting the occupants from the impact. Recently, in addition to airbags in front of the driver and passenger seats, side airbags that deploy from the sides of the seats to prepare for side collisions, as well as curtain airbags that extend along the windows, are becoming increasingly common. Meanwhile, the curtain airbag is equipped with an airbag cushion extending along the front and rear rows, and an inflator is installed to supply gas inside the airbag cushion. In addition, mounting tabs are partially fixed along the longitudinal direction of the airbag cushion, and by fixing each mounting tab to the vehicle body, the airbag cushion is secured to the vehicle body. However, since the mounting tab was fixed to the airbag cushion by sewing, there was a problem of increased manufacturing costs due to the need for multiple sewing operations to maintain the durability of the sewn part. Furthermore, since the mounting tab is made of a soft fabric material, sagging occurs due to the load of the airbag module even when the mounting tab is bolted to the vehicle body. Consequently, it becomes difficult to maintain the bolt's assembly torque, leading to a problem where the cushion's assembly performance is degraded. The matters described above as background technology are intended only to enhance understanding of the background of the present invention and should not be construed as an acknowledgment that they constitute prior art already known to those skilled in the art.
