Abstract
Disclosed is a means and method for attaching an automotive lighting lens to the housing of an automotive lighting assembly while a structural adhesive cures. An automotive lighting assembly has a recessed hollow portion dimensioned to enclose one or more light fixtures and an open end with a peripheral edge. Formed around the periphery of the housing is a sealing groove and a plurality of engaging openings adjacent the groove. The engaging openings have a plurality of protuberances projecting into the opening, the protuberances providing a reduced area of clearance within the engaging opening. A covering lens has an exterior edge and a flange dimensioned to extend into and mate with the sealing groove formed around the edge of the lens. A plurality of projections are formed on the lens and positioned to coincide and mate with the engaging openings and dimensioned to have a cross section that causes the projections to engage the protuberances to produce frictional engagement and retention when the projections are inserted into the engaging openings. A curable adhesive is positioned within the sealing groove. When the lens is pressed onto the housing, the flange mates with the groov…
