Motor vehicle with bodywork having openings closed by doors and flaps - has seal of flexible material with central cavity arranged between bodywork and opening assigned to each door and flap opening essentially along its periphery

摘要

The vehicle has a cavity (30) enclosed by walls (31) of a sealing gasket (3) forming at least one chamber sealed compared to the surroundings of the gasket. One of the walls at least is provided with a pressure fluid connection (32) opening and penetrating the gasket. A pressure fluid supply unit (40) communicates with the fluid connection, so that a pressure can be built up in the gasket chamber. The gasket is designed as a pressure tight cavity over its entire length. The cavity has several chambers acted on with pressure fluid independently from each other. ADVANTAGE - Reliable sealing of bodywork flaps and doors also at high speed.
