Movable Seats TRIZ Cases
- Disc Recliner Backlash Reduction via Asymmetric Pawl Wedging
An asymmetric pawl wedges between guides via a cam mechanism, eliminating backlash without requiring tight manufacturing tolerances.
- Vehicle Seat Link Rotation Inhibition via Dual Contact Portions
A vehicle seat bracket uses two width-separated contact portions to restrict link rotation during a crash.
- Vehicle Seat Slide Rail Rotating Member for Lateral Load Management
A vehicle seat slide rail uses a rotating member to redirect lateral spring forces, preventing lower rail deformation and reducing flip-up effort.
- Vehicle Seat Guide Frame Reinforcing Profile Force Transfer
A lower guide frame reinforcing profile with an oblique portion diverts vertical suspension forces along the slide.
- Ceiling-Mounted Wheelchair Backrest With Rail Stowage
A ceiling-mounted backrest arrangement uses a parallel rail system to pivot and stow the support unit vertically within the vehicle roof structure.
- Vehicle Cargo Conveyor Using Seat Motor Gearbox
A vehicle cargo conveyor system uses a seat motor gearbox to drive transport when seats fold.
- Seat Pivot Mechanism Linkage Pin Retention
Asymmetric linkage tube geometry retains enlarged head pin, preventing disengagement during vehicle impacts.
- Vehicle Seat Longitudinal Adjuster Crash Load Transmission
A longitudinal adjuster uses a shoulder to jam a crossbar between rails, transmitting crash loads through the spindle nut.
- Electric Seat Motor Mounting via Linear Sliding Guide
Linear sliding guides constrain the motor position during assembly, eliminating complex three-dimensional bending processes.
- Vehicle Seat Recliner Locking Gear Anti-Deformation Design
Segmented locking gears engage internal gear rims via cam mechanisms to prevent gap formation and structural deformation under external loads.
- Multi-position Backrest Latch with Cam Blocking Element
Cam element acts on movable blocking element engaging locking pin, eliminating play from manufacturing tolerances and absorbing vehicle vibrations.
- Vehicle Seat Recliner Cam and Pawl Mechanism
A seat recliner cam rotates a pawl to release the seatback for dumping.
- Vehicle Seat Backrest Blocking Device for Crash Safety
A vehicle seat backrest uses a blocking device coupled to the fitting arrangement to secure the pivot axis.
- Vehicle Occupant Posture Control via Predictive Actuation
Predictive seat adjustment and muscle stimulation align occupant posture with vehicle motion, reducing motion sickness caused by delayed response.
- Vehicle Seat Longitudinal Adjuster Memory Device Extraction
Extracting the memory device from inside the seat rails preserves structural stability while a friction wheel enables precise positioning.
- Vehicle Seat Rail Memory Actuation via Nested Gear Mechanism
Nested gears and an actuating arm control seat rail locking elements at memory positions, resolving safety complexity trade-offs.
- Auxetic Adjustment Device for Vehicle Seat Positioning
Auxetic cell structure expands transversely to adjust vehicle seat components without complex mechanisms.
- Vehicle Seat Coupling Folding and Displacement to Prevent Collisions
A vehicle seat control mechanism couples folding and longitudinal displacement movements into a single coordinated action.
- Tip Slide Mechanism for Vehicle Seat Ingress Access
A tip slide mechanism moves a vehicle seat assembly along a curved path to facilitate forward positioning.
- Linear Latch with Spring-Biased Gear Rack for Seatback Adjustment
Segmented gear rack and pawls resolve complexity trade-offs, enabling seamless bi-directional seatback adjustment.
