VENTILATING CROSS-MEMBER DUCT AND METHOD FOR MAKING A VENTILATING CROSS-MEMBER

摘要

The invention concerns a ventilating cross-member, and more precisely it concerns a method for making a ventilating cross-member comprising a metal beam (10) and a duct (16) designed to connect two openings (12, 14) between which it follows a winding path. The method includes making a beam (10) which delimits an enclosing volume for receiving the duct between the two openings (12, 14), making the duct (16) which is specifically reversibly deformable between a working state and a retracted inserting state, placing the duct (16) in its inserting state, inserting the duct (16) in the beam (10) through an opening (12, 14) thereof, and placing the duct (16) in its working state. The invention is applicable to motor vehicles.
