Fastening device for a heat shield and method to produce the same

机译:隔热罩的紧固装置及其制造方法

摘要

A heat shield for shielding of hot areas of a combustion engine. The heat shield has at least one metal sheet layer with a first and a second surface. The at least one metal sheet layer has at least one passage opening for the passage of a fastening element. The layer also has a sleeve which passes through the passage opening. The heat shield further has a decoupling element from flexible material arranged between a circumferential edge of the passage opening and the sleeve. The decoupling element and the sleeve each have a) an annular shank area, which penetrates the passage opening, b) a first collar, which on the first surface extends radially outward relative to the circumferential edge of the passage opening, and c) a second collar, which extends adjacent to the second surface radially outward relative to the circumferential edge of the passage opening.
