Seat cushion adjustment for vehicle seat - has mechanical drive providing movement between two extreme positions

摘要

The system is controlled in relation to a main adjustment. A separate adjustment is provided which establishes the run-out curve of the seat cushion adjustment within a limited adjustment range. The system has extreme positions coordinated with the main adjustment such that an over-shoot of the set outer adjustment position limits for the seat cushion adjustment is avoided. The control of the adjustment movements is achieved by a mechanical drive. ADVANTAGE - Provides a range of seating adjustment parameters, enabling an occupant to change posture and avoid fatigue.
