摘要

#CMT# #/CMT# The system has a case comprising tabs (20) connected to the case and extending parallel with respect to each other. The tabs are connected to a corresponding edge of a flap (12) engaged across a slot in order to retain the edge between the tabs, where the tabs and the flap are made of thermosetting or thermoplastic material. The tabs are molded with the case. One of the tabs includes an extension forming a projection with same thickness as that of a lateral wall of the case. The projection fills a space between ends of the tabs and an outer surface of the wall. #CMT#USE : #/CMT# System for fixing a flap of air extractor of motor vehicle on a case of the extractor that escapes air from inside a passenger compartment of the vehicle towards outside. #CMT#ADVANTAGE : #/CMT# The system fixes the flap to the case by inserting the edge of the flap in the slot, in an easy and rapid manner, without utilizing an additional mounting piece. The projection fills a space between ends of the tabs and an outer surface of the wall to ensure perfect sealing of the air extractor at the wall of the case, with good cladding of the flap on the case and by avoiding the presence of folds when the flap is of large dimensions. The flap possesses good resistance to failure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a detailed enlarged view of a fixing system after fixing a flap to a case. 12 : Flap 16 : Walls 17 : Fins 20 : Tabs #CMT#POLYMERS : #/CMT# The tabs and the flap are made of thermoplastic or thermosetting material such as ethylene propylene diene M-class rubber (EPDM).
