Abstract: An air filtration system for a vehicle cab has an air recirculation circuit which includes an air recirculation blower arranged in an air recirculation channel system in order to draw air from the cab interior and to blow it back into the cab interior. An air recirculation filter is arranged in the air recirculation flow. In order to reliably avoid contamination of the cab interior during filter changes, the air recirculation filter is located in a portion of an outer wall of the cab roof behind a cover. The cover covers the air recirculation channel system hermetically from the cab exterior. When the cover is opened, the air recirculation filter is accessible from the outside.

Abstract: A shelf assembly is proposed which can be taken apart and which has shelves (1) and rods (2) disposed for supporting the shelves in a nearly horizontal position. Cables (3) are provided to tension the rods (2) with the shelves (1) to fix the position of the rods (2) with respect to each other and of the shelves (1) relative to the rods (2). In addition, an attachment device is provided for connecting the cables (3) to the rods (2) in a detachable manner.
