SEALING DEVICE BETWEEN A PARTITION AND A FITTING SET IN FRONT OF AN OPENING FORMED IN THE PARTITION

摘要

The invention concerns a sealing device between a element (1) partitioning two separate zones (A, B) and a specific fitting (2) set in front of an opening (3) provided in the partition (1) against one of its faces housing a soundproof lining (4) so as to communicate said zones (A, B) mutually through the fitting (2) via a sealing joint. The invention is characterised in that said sealing joint is formed by the extension (4a) of the soundproof lining (4) itself, extending towards the peripheral edges (3b) delimiting the opening (3) of the partition (1) and by such value as to enable an integral peripheral contact with a peripheral zone (2a) of the fitting (2) to be installed. The invention is useful for fixing an air treatment unit on a firewall separating the engine compartment from the passenger compartment in a motor vehicle.
