Collapsible automotive trim panel boss

摘要

An automotive door interior assembly has an interior door trim panel with a plurality of bosses extending therefrom having sections of varying wall thickness for allowing energy absorption through columnar deformation of the bosses. The bosses comprise conically shaped, hollow pedestals having a first end attached to the trim panel, a second truncated end opposite the first end, a wall connecting the first end and the second end, and an inner surface on the wall having at least one groove thereon. Connectors on the second truncated end of the bosses attach the trim panel to receiving apertures in the inner door panel.
