Assembly with trim cover for housing an inflatable airbag

An assembly of the invention includes a two-section trim cover for covering a component of a vehicle. The outer surfaces of the trim sections are secured to each other thereby forming a plain seam, with margin portions of the trim cover folded inward of the outer surfaces. The assembly further includes a two-section cavity liner for directing the force of the inflatable airbag in a direction toward the plain seam. To prevent the margin portions of the trim cover from blocking the plain seam, the margin portions of the trim cover are secured to the liner sections. The margin portions of the trim cover are, however, secured to the liner sections without substantial penetration through the outer surfaces of the trim cover. For this reason, the assembly offers an aesthetically pleasing housing for an inflatable airbag as the stitching is substantially hidden from a vantage facing the outer surfaces of the trim cover.
