Abstract

A hose arrangement for a motor vehicle may include a flexible elongated bellows including a plurality of radially orientated pleats and two axial longitudinal ends. The hose arrangement may also include at least one reinforcement rib which, on an outside, is coupled to a pleat tip of a respective pleat of the plurality of pleats in a material-bonded manner via two-component injection moulding. The at least one reinforcement rib may engage about the respective pleat in a circumferential direction. The at least one reinforcement rib may have at least two rib segments disposed following one another in the circumferential direction. Each of the at least two rib segments may radially cover the pleat tip by a segment angle of 30° to 310° in the circumferential direction.
