(EN) The invention relates to a fender system with a spring-mounted fender which can be extended in the direction of the shock. It is the purpose of the invention to propose such a system which saves space and offers absolute damage protection for the vehicle even at high impact speeds. The principle of the invention is that the fender is suitably extended before or during the occurrence of the hazardous situation. Improvements in the system concern producing a progressive damping characteristic and providing a suitable drive for quick extension and reliable retraction of the fender.
