Flexible bellows for protecting e.g. steering gear-box, of motor vehicle, has pipe projected from peripheral delimiting wall of bodies and extended towards interior of bellows, where pipe and bodies are formed as single piece

摘要

The bellows (1) has tubular bodies (3A-3C) opened at each one of their ends. The bodies are made of thermoplastic material by molding or blowing of a preform. The bodies have a through pipe (2) for communicating an interior volume of the bodies with the exterior. The pipe is projected from a peripheral delimiting wall (4) of the bodies. The pipe and the bodies are formed as a single piece. The pipe is extended towards interior of the bellows. An independent claim is also included for a method for fabricating flexible bellows.
