Movable Seats TRIZ Cases

Fluid chambers automatically counter seat tilt in slanted vehicles, helping maintain neutral spinal alignment and reduce back strain.

A manually disengageable coupling lets a vehicle seat reach an easy-entry position when the electric drive fails, without added mechanism complexity.

Offset locking structures on both seat rail sides prevent tooth-on-web positions, enabling fast crash locking and stronger safety compliance.

Cam-actuated lock members and spring bias create a compact slide rail lock with multi-point slot engagement for stronger, more reliable locking.

A latch, elastic element, and movable rear hinge axis let the seat retract for rear access without overloading the slideway if the actuator fails.

A cam-track latch lets a vehicle seat switch between locked and easy-entry positions without electronics, improving reliability and access.

Fixing the motor and screw assembly to the slider keeps the screw aligned with the rail, enabling smoother seat travel with less noise and rattling.

Collision signals trigger brushless seat actuators to rapidly reposition occupants away from intrusion zones and reduce injury risk.

A friction ring on the seat drive output creates a torque threshold that masks reducer play and reduces noticeable seat movement changes.

A mode-switching seat slide layout enables a rearward relaxing position while limiting unsafe operation and reducing rail deflection and motor load.

A switchable detent lets occupants manually reposition a powered vehicle seat when motor actuation is unavailable, improving emergency egress.

A sliding element cuts friction at the seat fitting to control backrest displacement during crash overload and reduce occupant acceleration.

An electromechanical latch and track adjuster automates seat return from easy-entry to locked position, reducing manual effort and speeding motion.

A two-stage seat rail drive spreads transmission along the vehicle floor to enable long travel, flat-floor interiors, and crash-resistant seating.

A vertically adjustable seatback uses shifting frame components and geared locking to fit different torso lengths and improve shoulder and lumbar support.

Monitored seat temperature can override a recline request and keep the seat in a safe sitting position when crash safety is at risk.

Sensors detect reclined occupant posture and adjust seat back and base angles to reduce lap-belt abdomen loading during crashes.

A slip-fit encapsulating ring lets a seat recliner reach precise clearance, maintain torsional friction, and block debris and fluid ingress.

Dedicated longitudinal power feeders let multiple sliding vehicle seats share long rails while keeping seat electrical components reliably powered.

Deformable rings between the seat pedestal and track absorb crash energy, limiting seat travel during sudden deceleration.

During vehicle turns, the seat cushion and seat back pivot together to reduce torso-pelvis mismatch, driver discomfort, and fatigue.

Two spring-biased blocking members brace a vehicle seat slide rail to lock at unlimited positions, then separate for smooth release.

A mediated gas spring layout helps a tumble seat rotate into stowage while preventing slide rail distortion and preserving smooth rail movement.

A single latch and auxiliary lever hold a vehicle seat backrest at two angles while cutting part count and locking complexity.

Sequential seat-actuator feedback warns occupants of upcoming acceleration or deceleration, improving comfort and reducing motion sickness.

Pivoting paired cover elements snap over-centre above the seat rail to block dirt and liquids without seal deformation or poor load support.

A rail-integrated receiving profile guides seat adjustment cables with low friction, preventing damage and rattling over long travel paths.

An upward-moving lock pin avoids floor panel interference, preserves EV battery mounting space, and simplifies seat rail assembly.

A rocker arm, linear actuator, and connecting rod lift a vehicle seat vertically while minimizing horizontal displacement and re-adjustment time.

An aligned guide and actuator adjust seat belt position in tight vehicle space while transmitting crash loads effectively.

A passive rocker-and-tie-rod linkage synchronizes backrest frame ends to prevent torsion under asymmetric force and reduce seat wear.

Elastic support and an inserted force element keep seat rails evenly spaced for smooth sliding while reducing vibration, noise, and sticking.

A pivoting spring-biased stopper blocks seat encroachment while letting a second seat move close on the same track.

Two-stage sensor feedback pre-adjusts and fine-tunes vehicle seats to cut manual setup time, distraction, and comfort mismatch.

A linked support and board rotation lets a vehicle entry aid switch between horizontal use and upright storage in one simple motion.

A belt-driven rail with pulley and pressing members replaces screws and wires to cut noise, weight, and size while supporting long seat travel.

Multiple spring-biased locks engage fixed rail holes to remove seat rail play, cutting BSR noise and repeated impact damage.

A pivoting seat frame and ground support leg let the chair swing outside the vehicle, reducing entry and exit strain for disabled users.

Resistance, RFID, or NFC sensing identifies a vehicle seat's installed position accurately, cutting installation time and alignment errors.

A person model and interior-element kinematics predict uncomfortable postures during motorized vehicle interior adjustment and reshape the path.

A load member and lateral side elements create a direct seat-to-floor load path that limits rail deformation during vehicle impacts.

Movable and fixed deflecting rollers keep a seat adjustment cable under tension, preventing slack, rattling, twisting, and breakage.

Guide pins and brackets let a vehicle seat recline, slide, and tip up without separate recliner parts, cutting weight, cost, and assembly effort.

Limits seat movement time while driving to prevent accidental adjustment and keep the driver's foot in contact with the pedals.

A block-shaped bushing directly fixed to the recliner plate supports the hinge pin while cutting seat support mass, size, and assembly complexity.

An inverted gear below dual toothed belts protects the seat rail drive from debris while adding damping for stable long-travel adjustment.

Automatic seat posture and position adjustment matches the selected in-vehicle display area to reduce effort and improve video viewing comfort.

A single rail-and-link seat mechanism replaces separate walk-in, relaxation, and full-flat folding parts to cut cost, weight, and assembly labor.

A pinned two-member seat track stud allows roll and pivot motion to cut seat leg preload and protect the track during pitch and roll testing.

A cam lever and memory plate cut seat track friction while restoring the seat accurately from easy-entry to the saved position.
