A flexible channel-shaped strip structure (5), such as a sealing strip for sealing around a door opening in a motor vehicle body, has a channel-shaped gripping portion (6) for grippingly engaging a flange running around the door opening. The gripping portion (6) supports a sealing portion (8) around the frame of the opening which is sealingly compressed by the closing door. The gripping portion (6) comprises plastomer or elastomer material (14) in which is embedded a resilient reinforcing carrier (12). A first part (14A,14B), only, of the extruded material (14) is of cellular form so as to undergo a reduction in volume when compressed, and the remainder of the extruded material (14) is non-cellular so that it undergoes substantially no reduction in volume when compressed. The extra-compressible cellular material (14A,14B) is so positioned within the channel shape as to facilitate longitudinal bending of the strip around a bend, the extra compressibility of cellular material (14A,14B) facilitating this bending. <IMAGE> |
