  • Patent number: 6623832
    Abstract: A sealing strip, such as for fitting to the frame of a door opening in a motor vehicle body, comprises a longitudinally extending channel-shaped mounting portion incorporating a channel-shaped reinforcing carrier. The hollow tubular longitudinally extending sealing portion is attached to the outside of the mounting portion. When such a strip is bent to follow curves in the door frame, the increased tension in the mounting portion at the curves can cause the sealing portion to move inwardly of the curve so as partially the bridge across the curve. In order to avoid this, the sealing strip, and particularly the mounting portion are longitudinally compressed at positions corresponding to the positions where curves are to be formed in the strip. This local longitudinal compression helps to maintain the sealing portion in its correct attitude.

    Abstract: A sealing strip, such as for fitting to the frame of a door opening in a motor vehicle body, comprises a longitudinally extending channel-shaped mounting portion (8) incorporating a channel-shaped reinforcing carrier (20). A hollow tubular longitudinally extending sealing portion (10) is attached to the outside of the mounting portion (8). When such a strip is bent to follow curves in the door frame, the increased tension in the mounting portion (8) at the curves may cause the sealing portion (10) to move inwardly of the curve into the position shown in the dotted line In order to avoid this, the sealing strip, and particularly the mounting portion (8), is longitudinally compressed at positions corresponding to the positions where curves are to be formed in the strip. This local longitudinal compression helps to maintain the sealing portion (10) in its correct attitude.
