Abstract
Mounting assemblies can be used to attach an inflatable curtain airbag to a vehicle structure. Mounting assemblies can include a mounting member, a connecting member, and an optional wrapper. The connecting member is attached to the mounting member and the airbag via stitching, which can be categorized according to the primary direction of stress that may be placed on the stitching during airbag deployment. Stitching in shear is stronger than otherwise identical stitching in peel; however, a preferred method of packaging a curtain airbag results in a b-rolled airbag that can not be attached to the connecting member with shear stitching alone. Peel stitching alone may not be strong enough to retain an occupant within the vehicle during a rollover event. As such, a combination of a folded connecting member, shear stitching, and peel stitching allows a b-roll airbag to meet occupant ejection mitigation requirements.
