In this VW camper, a private customer was looking for a solution to create a sleeping space for an additional person. The problem was that the space in the vehicle was already so limited that the solution required a special idea. In the end, the customer's idea was to install a fold-down bed in the ceiling space directly above the driver's cab. The retraction system for raising and lowering the bed was a rope guide. Since a pulley system always requires a winch, the customer asked us for plain bearings to absorb the tractive force, enabling easy raising and lowering while remaining compact enough to fit into the tight installation space.
