VEHICLE SEAT SUSPENSION Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: invention relates to seats of vehicles, namely, to suspensions of seats of locomotive drivers operating under conditions of high vibrations. Proposed suspension of seat contains telescopically coupled guides connected with base and skeleton of seat cushion, elastic member installed between guides, shaped cam engaging with contact members provided with rollers, and adjusting device in form of screw pair. Suspension is provided with bracket installed inside guides, roller pairs installed between telescopic guides at ends, flexible supports to provide protection in horizontal plane and made in form of base movably resting of rod. Contact members are made in form of elastic cantilever rods whose other are press-fitted into ring, cantilever rods being installed on bracket by means of ring and elastic member. Guide is connected with base by means of threaded joint, thus forming above- indicated screw pair playing the part of suspension adjuster to suit weight of operator checked by coincidence of mark on outer surface of guide and indicator of suspension base. EFFECT: improved efficiency of spatial vibration of suspension. 3 dwg
