Methods for making an airbag mounting bracket for use with an attachment component of an associated airbag cushion are provided. An opening in a mounting bracket precursor formed of a bracket precursor material is extruded. A rounded surface of the bracket precursor material adjacent the extruded opening is formed. The mounting bracket precursor with the rounded surface is subsequently finalized to form the airbag cushion mounting bracket, wherein the extruded opening provides an airbag attachment engagement opening for passage of the attachment component and the rounded surface provides a load bearing surface of increased area for the attachment component. Also provided are corresponding or associated airbag mounting brackets.
