Movable Seats TRIZ Cases

A nested rail layout houses the gearbox, rack, and pinion inside the seat track to prevent floor debris from causing power-adjustment failure.

A tilting link and sliding bracket increase seat-to-luggage-box clearance, enabling stable fold, relax, and backward relax modes.

A movable rear seat bottom and folding seat back create a flat storage surface while preserving passenger seating when needed.

A modular moving component and simple connecting interfaces enable headrest height adjustment while reducing seat assembly space and disassembly complexity.

Spring-preloaded slides and a toothed rack compensate wear and tolerances to keep vehicle seat adjustment smooth, quiet, and play-free.

A motor-driven linkage moves a seat portion through retracted, intermediate, and extended positions to add leg support without a bulky adjuster.

A single seat handle uses directional actuation to unlock backrest recline and operate another adjustment lock, reducing control clutter.

A lever switch triggers an actuator to pull the recliner cable, cutting user force while keeping seatback angle adjustment semiautomatic.

Multiple through-holes and a cap-based interface let seat track fittings switch seat pitch in half-inch increments with less part replacement.

A lever-driven support element expands backrest head adjustment beyond typical limits while keeping shoulder support and headrest positioning flexible.

A five-joint seat kinematics with a spindle linear drive expands recline range while acting as a crash compression strut to reduce spine loads.

A sliding, pivoting high latch lets a rear seat back recline, slouch, and fold flat despite limited space behind the seat.

Vertical stacking of lift, swivel, gear, and brake modules frees floor space while enabling accurate seat height adjustment and rotation.

Spring-preloaded conical projections lock upper and lower seat rails, removing play for quieter operation and higher load bearing.

A pressure tongue and rotating block lock the seat slider within the rail, reducing module space, parts, and installation complexity.

A guided angle reference member keeps the seatback detection point stable during seat tilting, preventing recline sensing errors and false restraint activation.

A motor and gear-linked seat raises the front leg, reclines the seatback, and deploys lower leg support for more ergonomic stationary comfort.

Dual eccentrics with wedge segments remove gear-sprocket backlash in a vehicle seat joint fitting while supporting higher loads in less space.

A linked rotating board and support arm enable one-action entry assistance stowage while damping motion to prevent unintended rotation and finger trapping.

Oblique multi-part engagement slots stabilize screw contact in electric slide rails, reducing positioning error, noise, and harness load.

A shift restrictor and spring-biased engagement member keep a sliding rail locked during vehicle bounce without excessive engagement force.

A stepped gear housing adds axial worm gear support to absorb and direct crash loads, improving seat adjuster rigidity and load capacity.

A locking arm switches between fixed and movable seatback rotation states, while a fluid-filled chamber resists compression for controlled comfort.

An electronic controller disables the seat switch outside park to prevent unintended seat movement while preserving third-row access when parked.

Sensors detect operator body size and weight to auto-adjust seat position, recline, height, and steering angle for better comfort and less fatigue.

A bar-shaped biasing member simplifies upper-rail assembly while maintaining lock position and enabling reliable seat slide release.

A hinge-mounted sub-seatback layout enables forward- and rear-facing seating, bed mode, and tip-up access with fewer parts and lower seat weight.

A track-guided rear seat support switches between passenger use and forward or rear cargo space while locking securely for stability.

A lever, cable, and spring linkage folds, tilts, and slides a vehicle seat in one action, cutting lock complexity, weight, and cost.

A vertically displaceable footrest increases seat-to-footrest distance as the seat rises, improving posture stability and eye height.

A constrained link and interlocked folding, tilting, and sliding units simplify vehicular seat walk-in motion while cutting locking complexity and cost.

A cam-locked seat track unlocks for sliding and supports manual or powered seat repositioning to free cabin space for passengers or cargo.

Rotating seat bases and foldable leg supports add stationary cargo-space seating while preserving floor area through sidewall stowage.

A motor-driven linkage lifts the rear seat cushion front edge for comfort adjustment and pre-collision passenger restraint.

A sliding connector engages pre-mounted floor attachments to secure a long vehicle seat rail where central screw access is limited.

A nested rail and downward-facing rack shield the seat drive from floor debris, preserving smooth power adjustment and reliability.

A flanged, offset seat link controls rear-collision backward tilt while reducing load on the sector gear and limiting gear damage.

Dynamic pinch thresholds tied to backrest angle improve seat motor pinch detection accuracy and reduce false stops.

Two-direction pressing forms a tubular seat adjuster lever without cutting, reducing production steps while preserving a closed, stronger end surface.

Cable tension retracts a tapered locking pin through pulleys to reduce post-lock seat movement while keeping swivel release easy.

A variable-section mobile flange cuts forging blank size and weight while preserving gear strength and durability in seat recliners.

A rearward hinge axis and rear coupling let the seat tilt forward while keeping under-seat space smaller and reducing step-in risk.

Coordinated X- and Z-locking lets a vehicle fixture stay secure on the guide rail yet release and remove easily with fewer actuators.

A seat position sensor triggers automatic seatback restoration at a preset slide point, preventing unintended deployment and simplifying entry.

A centralized controller calculates seat interference coordinates to prevent collisions and coordinate motion across multiple vehicle seats.

A telescopic seat lift raises grocery scooter users up to 24 inches, helping them reach upper shelves independently while staying secured.

Driver-state checks govern seat repositioning during manual and automatic control transfer to avoid spills, laptop contact, and rear-seat disturbance.

A spring-biased gearbox keeps the seat rail drive wheel meshed with the gear rack despite tolerance stack-up, dimensional variation, and road vibration.

An electric lateral drive wheel and spring-loaded rolling elements automate seat travel while absorbing rail channel variation for quieter, steadier motion.

A semicircular rack with special-shaped end teeth enables compact 0-180° seat rotation while preventing over-rotation and wire harness breakage.
