Movable Seats TRIZ Cases
- Vehicle Seat Rail Mechanism for Rotational Entry
A vehicle seat rail mechanism uses a spring unit to rotate the seat shell toward the door opening, resolving entry stability trade-offs via memory devices.
- Vehicle Seat Adjustment Mechanism with Overlapping Electric Drives
Overlapping electric drives reduce installation volume while enabling precise longitudinal and rotational seat adjustments.
- Motor Vehicle Seat Rail Guide Accident Force Absorption
A longitudinal rail guide uses a deformable free edge to increase locking security during vehicle seat operation.
- Vehicle Seat Leaf Spring Four-Bar Linkage Kinematics
Replacing pneumatic springs with a mechanical leaf spring reduces device complexity while maintaining reliable backrest support stability.
- Seat Recliner Interlock Mechanism for Full-Forward and Fold-Flat Locking
A seat recliner interlock mechanism uses a biased lock plate to secure the seatback in full-forward or fold-flat positions via a single handle.
- RFID-Based Automatic Seat Adjustment System
A seat adjustment system uses RFID readers and pressure sensors to detect user presence and retrieve stored position data, eliminating manual intervention.
- Fixed Structure Seat Slouch Adjustment Mechanism
A vehicle seat uses sliding members and pivotable connections to enable unconventional slouch adjustments.
- Vehicle Seat Positioning System with Proximity Control
A vehicle seat positioning system uses occupancy and proximity sensors to command seat movement away from adjacent seats when distance falls below a threshold.
- Vehicle Seat Link Rotation Limiting via Dual Limiter Segmentation
Segmented front and rear limiters maintain rotation control on the seat link member, preventing deformation-induced loss of stability during vehicle collisions.
- Curved Rail Guide for Simultaneous Seat Height and Tilt Adjustment
A curved rail guide system moves a vehicle seat along a circular arc path to provide integrated height and tilt adjustments.
- Vehicle Seat Pumping Device Return Spring Design
A vehicle seat pumping device uses a ring-shaped return spring that changes diameter to rotate the handle lever.
- Seat Support Mechanism With Torsion Bar Vibration Absorption
Torsion bars extend across the cushion frame width to absorb vibrations, maintaining consistent elasticity regardless of lifter height adjustments.
- Vehicle Seat Recliner Merging Control and Input Members
Merging control and input members eliminates retaining rings, reducing component count and assembly tolerance in vehicle seat recliners.
- Vehicle Seat Shaft Axial Locking Design
Flared shaft ends prevent pull-out during rear-end collisions, maintaining stability without adding complexity.
- Seat Travel Limiter Nut with Elastic Segmentation
Segmented nut portions with varying elasticity differentiate driver and passenger seat travel ranges without adding limit stops.
- Recessed Seat Track End Cap Sensor Detection
Segmenting the end cap into a main body and a recessed wall resolves interference with the seat position sensor, ensuring accurate detection range.
- Dual Roller Rail Assembly NVH Reduction
Segmented rollers on a common axle minimize noise and vibration in vehicle seating assemblies without secondary axles.
- Integrated ECU HMI Unit Thermal Management via Side Shield Heat Sink
An integrated electronic control unit and human machine interface share a common printed circuit board within a vehicle seat side shield.
- Vehicle Seat Lifter Friction Cam Switching Mechanism
A vehicle seat lifter uses a rotating cam to switch a clutch portion between friction-suppression and friction-on states.
- Elliptical Bushing Pivot Pin for Smooth Seat Back Rotation
An elliptical bushing mediates a pivot pin within a mounting bracket to enable smooth rotational movement of a vehicle seat back.
- Movable Vehicle Seat Cushion Rotates to Expose Storage
A movable seat cushion rotates and translates to expose underlying storage areas for rear passengers.
- Vehicular Seat Slide Spring Locking Mechanism
Integrated spring locking portion eliminates complex assembly steps by combining positioning and fastening functions within the seat slide mechanism.
- Vehicle Seat Backrest Sliding Guide for Lateral Displacement
A vehicle seat backrest upper part moves laterally via a sliding guide device to provide torso support.
- Vehicle Seat Suspension Device with Inverted Rocker Movement
An inverted rocker mechanism moves the upper suspension part backward during deflection, relieving harmful loads on knee joints and the back.
- Vehicle Seat Rear-Entry Mechanism with Track Overslide Lock
A vehicle seat mechanism uses a pivot cam to activate a track overslide actuator for forward sliding.
