Movable Seats TRIZ Cases

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

A three-part pivoting seat switches between forward and rearward facing without disassembly while preserving leg space, lumbar support, and comfort.

Filters repeated walk-in switch signals during seat movement so unintended return is ignored and passenger injury risk is reduced.

When a seatback reclines, linked armrest sliding keeps a preset gap stable, improving occupant comfort and preventing narrow or wide spacing.

Occupant force and sensor feedback release a self-locking floating seat, enabling motor-assisted positioning without manual unlocking.

A crank-driven cam unlocks the seat track for manual or powered movement, balancing stable locking with flexible sitting-to-standing repositioning.

A crash-triggered seat rail unlocks a fastening member so a deformation element absorbs impact energy and slows seat travel.

Movable backrests and a height-adjustable table turn passenger benches into a flat, accessible luggage area with higher storage volume.

Occupant-aware seat path control slows, shortens, or cancels seat movement to prevent interference with nearby passengers.

A rope-actuated seat rail release lets users adjust a vehicle seat longitudinally while upright, avoiding awkward bending below the cushion.

A rotatable second-row center seat shifts between mounting points to clear rear carrier travel and improve luggage loading convenience.

A single-motor rack-and-gear seat lift adjusts height and movement direction while improving support stability and impact load distribution.

An auto-centering gearbox coupling lets vehicle seats quickly attach to a powered rail and self-align for smooth repositioning.

Sliding rails, linkages, and lifting brackets fold and stow a third-row seat to free cargo space without cushion compression or awkward gaps.

A modular scissors-frame seat spring uses deformable rigid foam and rotatable links to cushion longitudinal motion with less friction and maintenance.

Preloaded spring-assisted pivot links let a vehicle bench seat shift forward or rearward with less bulk, weight, and effort.

A swivel stop and base plate vary seat rotation by fore-aft position, keeping vehicle controls reachable while allowing rearward viewing.

A clevis-and-pulley pull strap cuts the force needed to release a vehicle seat recline mechanism while simplifying bulky lever hardware.

When the operator leaves, presence sensing triggers automatic seat fore-aft or height adjustment to ease heavy-duty vehicle entry and exit.

A crash-responsive blocking element stops uncontrolled seat lowering by locking the guide path, reducing submarining risk without hindering normal folding.

A mechanical linkage deploys the lower leg support as the seat reclines and rises, improving comfort without separate manual adjustment.

A rotating anchorage keeps the child seat top tether aligned on swivel vehicle seats, preventing belt twist and preserving stable mounting.

Rail-mounted seats with actuators and occupancy sensing enable on-demand cabin layout changes for comfort, social use, child care, or cargo.

A detachable gearbox and latch interface lets vehicle seats keep power sliding adjustment while remaining easy to remove and reconfigure.

Angled through-fasteners in the seat rail surround the gear housing to absorb crash loads in double shear and keep the seat attached.

A spring-biased locking pawl with two receptacles lets a vehicle seat backrest lock securely at two inclination settings.

Longitudinally crowned worm gearing localizes tooth contact to cut seat adjuster noise, vibration, and misalignment sensitivity.

Two seat rails linked by transverse struts absorb longitudinal and lateral loads, cutting support complexity and manufacturing cost.

Dynamic seat-state and environment sensing adjusts active suspension to improve vibration isolation and avoid interior collisions.

Magnetic locking powered through the rail simplifies vehicle seat or console sliders, cutting structure height, wiring complexity, and space use.

Dual actuator link arms split frontal collision loads across both seat sides, preserving compact size and a wide inclination range.

A conical spiral gear and planetary gearbox cuts seat adjuster height while preserving anti-back drive and long-travel rack-and-pinion motion.

Phase-shifted propulsion elements engage a seat-adjustment rack to deliver compact, low-play, quiet linear motion without extra gear units.

A cam-linked side frame folds the headrest during seat movement, reducing mechanism complexity and avoiding occupant obstruction.

A detachable rear seat uses latch, striker, and sliding-locking mounts to form an adjustable hammock-like rest that improves body pressure distribution.

Tapered shaft and lock tooth faces, loaded by a wave washer, remove seat slide play to cut rattling, wear, and noise.

A four-bar linkage lets a rail end cap absorb opening-to-edge tolerance variation, reducing play and improving seat adjuster assembly.

A reinforced open-end gear holder fits inside the seat rail to simplify bottom-up assembly and prevent travel noise in motorized seat adjusters.

A central dual-gear recliner merges seatback and cushion drivers to cut weight and enable back table, leg rest, and large-angle seat modes.

Sloped rail groove ends let the seat lock transition smoothly, preventing partial fixation, noise, and vibration during sliding.

A memory seat track stores the chosen fore-aft position, enables easy-entry sliding, and returns the seat automatically without readjustment.
