Sealing unit for a hollow profile of a car body

摘要

The unit has frames (2) comprising side walls (3) extended in a direction of a longitudinal axis of a hollow profile (10). The side walls of the frames are arranged in such a manner that the side walls correspond to a form of a cross section of the hollow profile. The side walls are provided with a wall seal for sealing of the frames in an inner wall of the hollow profile. Movable sealing components (6, 7) of space sections are designed as a throttle plate, for sealing the space sections in the direction of the longitudinal axis of the hollow profile.
