Seat Suspension Devices TRIZ Cases
- Air-Spring Vehicle Seat Damping With Pressure-Adaptive Hardness
Air spring pressure automatically adjusts seat damper hardness to match driver weight and road vibration, improving comfort and end-stop protection.
- Vehicle Seat Suspension Damping Control to Prevent Bottoming Out
Sensor-based damping control switches modes from normal to maximum damping when seat motion exceeds thresholds, reducing vibration and bottoming out.
- Active Suspension Attitude Control for Injured Occupant Support
Occupant condition data corrects active suspension attitude control to reduce resonance-frequency vibration and improve support during vehicle motion.
- Active Seat Suspension Using Prefiltered Road Data for Phase-Delay Control
Prefiltered road data lets the seat suspension anticipate high-frequency inputs while avoiding phase-delay issues on low-frequency hills and curves.
- Suspended Vehicle Seat Safe Mode for Unoccupied Operation
Occupancy sensing switches a suspended vehicle seat into a protective mode that locks position and raises damping to prevent suspension damage.
