SYSTEM ZUR BEFESTIGUNG VON ISOLIERMATTEN AUF EINER TRÄGERSTRUKTUR |
摘要 |
A barrier wall (20) separating a passenger compartment from an engine compartment of a motor vehicle has an acoustical barrier assembly (10) mounted thereto. The acoustical barrier assembly (10) includes a sound barrier layer (12) of a molded construction and sound dampening characteristics. At least one fastener (28) is integrally molded as a single piece with the sound barrier layer (12). The fastener (28) includes a plurality of outer spacer ribs (30) that project laterally from a tube (32) and space an inner surface (24) of the sound barrier layer (12) away from the barrier wall (20). A circumferentially extending flange head (34) is integral with the tube (32) and includes a first frusto-conical section (36) and a second inverse frusto-conical section (38). The annular bases of the first and second sections (36, 38) are integrally formed together while a lower end of the second section (38) is integrally formed with the tube (32), such that insertion of the flange head (34) through a barrier wall aperture (46) requires less force than removal of the flange head therefrom. |
