ABSTRACT:
An insulation part (1) for acoustic insulation or sound absorption and preferably to serve as moisture barrier, which can be arranged in a hollow space (6) created by an outer wall (4) and an inner wall (3) of an automobile door (2), said insulation part being profiled and having a basis of foam and a continuously, approximately constant thin cross section as compared with the space between the inner surfaces of the outer wall (4) and the inner wall (3). In this connection, in order to obtain a simple but effective development, a bead (7) of substantially U-shape in cross section, developed, in particular, on the edge side and leads to a supporting of the single-layer insulation part on the inner surfaces of both the inner and the outer wall, is provided, a freely swingable section (13) of the insulation part (1) extending between two such bead formations (7, 8, etc.) which rest against both inner surfaces.
