  • Rigid backbone enhancement for extruded profiles
    Patent number: 5437124
    Abstract: A weatherseal includes a supporting carrier, a body of elastomeric material formed on the carrier, a layer of decorative material disposed on a surface of the body, and a backbone of longitudinally incompressible material disposed between the decorative layer and the carrier for reducing wrinkling of the decorative layer when the weatherstrip is bent on a radius with the decorative layer inside. Another strip disposed adjacent to an irregular carrier eliminates irregularities from the surface of a thin portion of the elastomeric body and improves the appearance of the weatherseal.
