Abstract

A flexible, resilient sealing strip for motor vehicle doors, comprises a U-shaped gripping portion (2) enabling the strip to be fixed on a projecting part of the door, and a tubular sealing portion (4) of a cellular elastomer co-extensive with the gripping portion (2) along the length of the strip such that when in use, the sealing portion (4) is compressed between the door and the frame providing a tight seal. The sealing portion (4) is reinforced at those portions of the sealing strip which correspond with corner portions of the door, by a moulded insert (16) of compact elastomer, inserted and moulded into a slit formed in the tubular sealing portion by making a slit in the tubular sealing portion (4) corresponding to a corner part of a door and inserting a metallic insert (8) of arcuate and flared out shape, into the tubular sealing portion (4). The sealing strip (4) equipped with the insert (8) is then introduced into an injection mould (10,11,12) where it acts as a core for the injection of a compact elastomer lip (16). The sealing strip is then removed from the injection mould (10, 11, 12), the insert (8) extracted from it and the free edge of the compact elastomer lip (16) is sealed to the opposite portion of the tubular sealing portion (4) to reconstitute the latter.
