Cover for a pressure relief valve assembly of a vehicle, a pressure relief valve assembly having such a cover, and a method for producing a corresponding cover

A cover for a pressure relief valve assembly of a vehicle,

• wherein
• the cover comprises a base body made of a sound-absorbing material which is uniform in terms of the material composition, wherein the base body is designed to be self-supporting and is connectable to an edge region of a pressure relief valve assembly;
• wherein the base body is a one-piece, monolithic base body and comprises side walls and a cover region, which together delimit a three-dimensional muffler space;
• wherein, during the production of the base body, the sound-absorbing material in an end region of the side walls opposite to the cover region and in a wall of the cover region has been compressed or otherwise compacted, at least partly or regionally such that at least one of the side walls and the wall of the cover region are configured with first segments having a first thickness and second segments having a second thickness that is less than the first thickness, wherein the first segments extend in a continuous manner from the one of the side walls and onto the cover region, wherein the second segments extend in a continuous manner from the one of the side walls and onto the cover region, such that the base body is configured with increased rigidity and/or strength in the end region.
