Patent FR-2535953-A1 (FR)
Title: Sealed watertight slide fastener
Inventor: APEL ALOYS
IPC: A44B19/32
Filed: 1983-10-12
Abstract: The lower slide fastener chain and upper slide fastener chain are each connected by vulcanised-in left and right sealing  strips (10). In the open position the slide fastener links (5,6) occupy a predetermined inclined position, the sealing strips (9,10) are relaxed and adjoin the links and the stitching seam (7,8) with the support tapes (3,4) adjoin the reverse sides (13) of the links. The sealing strips are greater in volume than the hollow space formed between the chains of links when the latter are closed and brought into the horizontal position.  This ensures that when the slide fastener is closed, the sealing strips are fully tensioned, proving an effective water and gas tight seal withstanding high dynamic pressure and strain.
