Dashboard aeraulic cross-member for motor vehicle, has sleeve shaped interface device extending through opening in channel of beam and having joint made of deformable material, where channel has duct with another opening defined by mouth

摘要

The cross-member has a beam (12) forming a channel (13) along the length of the beam, where the channel has an opening (14) on one of its side faces. The channel has a duct (15), made of a rigid insulating material, with an opening defined by a mouth located opposite the opening (14). The duct opening is slightly smaller than the opening (14), and is located inside the channel. A sleeve shaped interface device (16) extends through the opening (14) and has a joint made of deformable material.
