ABSTRACT:
A rolling-type bellows for vehicular pneumatic cushioning systems. In the installed state, support surfaces of the bellows that are adjacent to the end beads thereof are supported against vehicle parts that are movable relative to one another; the axial width of the support surfaces can vary. In the region of the annular support surfaces, the bellows are provided with raised interval axial ribs, which enhance the buckle-free continuous movement of the rolling folds, and reduces wear of the walls of the bellows.
