In some embodiments, a mounting plate for mounting an inflatable curtain airbag assembly to a vehicle may comprise a plate having a stiffness greater than a stiffness of a tab of an inflatable curtain airbag assembly to which it is attached. An opening may be formed in the plate, the opening being configured to receive a first fastener therethrough. A second fastener, such as a non-threaded fastener, may be fixedly and/or integrally coupled with the plate and may extend from one side of the plate. ## Claims ### Claim 1 An inflatable curtain airbag assembly, comprising: an airbag module comprising an inflatable curtain airbag cushion; and a mounting plate configured to couple the airbag module within a vehicle, wherein the mounting plate comprises: at least one opening; and a non-threaded fastener extending from one side of the mounting plate, wherein the non-threaded fastener comprises a self-holding, insertable retaining device configured to hold the inflatable curtain airbag cushion in place temporarily without any additional fasteners or coupling features, and wherein the non-threaded fastener comprises an integral extension of the mounting plate; and a mounting tab extending from the airbag module, wherein the mounting plate is coupled to the mounting tab, wherein the mounting plate has a greater stiffness than the mounting tab, wherein the mounting plate is sewn to the mounting tab, wherein the mounting plate comprises a plurality of adjacent openings, and wherein the mounting plate is sewn to the mounting tab with the mounting tab positioned behind the plurality of adjacent openings. ### Claim 2 (depends on 1) The inflatable curtain airbag assembly of claim 1, wherein the mounting tab comprises a fabric mounting tab. ### Claim 3 (depends on 1) The inflatable curtain airbag assembly of claim 1 wherein the mounting plate is sewn to the mounting tab along a line extending along and in between at least a subset of the plurality of adjacent openings. ### Claim 4 (depends on 1) The inflatable curtain airbag assembly of claim 1, wherein the at least one opening comprises an at least substantially centrally positioned opening configured to receive a bolt therethrough to permanently mount the airbag module to the vehicle. ### Claim 5 (depends on 4) The inflatable curtain airbag assembly of claim 4, wherein the at least one opening further comprises the plurality of adjacent openings extending about at least a portion of a periphery of the at least substantially centrally positioned opening, and wherein the mounting plate is sewn to a portion of the airbag module along a line extending along and in between at least a subset of the plurality of adjacent openings. ### Claim 6 (depends on 4) The inflatable curtain airbag assembly of claim 4, further comprising a washer coupled with the bolt, wherein the non-threaded fastener is spaced apart from the at least substantially centrally positioned opening to allow for a portion of the washer to be positioned between the non-threaded fastener and the at least substantially centrally positioned opening without overlapping with the non-threaded fastener. ### Claim 7 (depends on 1) The inflatable curtain airbag assembly of claim 1, wherein the non-threaded fastener comprises a resilient pushpin, and wherein the pushpin is integrally formed as part of the mounting plate. ### Claim 8 (depends on 1) The inflatable curtain airbag assembly of claim 1, wherein the non-threaded fastener comprises a circular shape in cross-section, at least in part. ### Claim 9 (depends on 8) The inflatable curtain airbag assembly of claim 8, wherein the non-threaded fastener comprises a pushpin, and wherein at least a portion of the pushpin is resiliently flexible such that the pushpin is configured to allow for partial deformation thereof as the pushpin extends through an opening of a vehicle and resume an initial shape of the pushpin after extending through the opening to temporarily affix the inflatable curtain airbag assembly to the vehicle during assembly. ### Claim 10 (depends on 9) The inflatable curtain airbag assembly of claim 9, wherein the pushpin comprises a plurality of resiliently flexible, concentric flaps. ### Claim 11 (depends on 10) The inflatable curtain airbag assembly of claim 10, wherein the plurality of flaps comprises a first set of adjacent semi-circular flaps and a second set of adjacent semi-circular flaps, wherein the first set of flaps is spaced apart from the second set of flaps by opposing slits. ### Claim 12 A method for mounting an inflatable curtain airbag module within a vehicle, the method comprising the steps of: aligning a first opening of a stiffener piece of the inflatable curtain airbag module with a first opening of a vehicle; inserting a first fastener into a second opening of the vehicle, wherein the first fastener is fixedly coupled with the stiffener piece, wherein the first fastener is non-threaded, wherein the first fastener is configured to hold the inflatable curtain airbag module in place temporarily without any additional fasteners or coupling features, and wherein the first fastener comprises a set of concentric flaps configured to resiliently deform; and inserting a second fastener into the first opening of the stiffener piece and into the first opening of the vehicle to mount the inflatable curtain airbag module to the vehicle; and sewing the stiffener piece to a fabric tab of the inflatable curtain airbag module. ### Claim 13 (depends on 12) The method of claim 12, wherein the stiffener piece comprises a plurality of adjacent openings extending about the first opening of the stiffener piece, and wherein the step of sewing the stiffener piece to the fabric tab comprises sewing the stiffener piece to the fabric tab along portions of the stiffener piece extending between adjacent openings of the plurality of adjacent openings. ### Claim 14 (depends on 12) The method of claim 12, wherein the first fastener comprises a resilient pushpin, and wherein the step of inserting a first fastener into a second opening of the vehicle comprises pushing the resilient pushpin into the second opening of the vehicle. ### Claim 15 (depends on 14) The method of claim 14, wherein the second fastener comprises a threaded bolt, and wherein the step of inserting a second fastener into the first opening of the stiffener piece and into the first opening of the vehicle to mount the inflatable curtain airbag module to the vehicle comprises inserting the threaded bolt through a washer, through the first opening of the stiffener piece, and through the first opening of the vehicle. ### Claim 16 (depends on 12) The method of claim 12, wherein the first fastener comprises an integral extension of the stiffener piece.
