By housing the motor and spindle drive inside the headrest, this case cuts backrest installation space while keeping powered adjustment force.

A non-circular hinge pin engagement part locks the biasing member without a slit, preserving shaft strength and freeing space for added components.

Dual worm wheels and eccentric fulcrum support cut backlash and whirling vibration while keeping seat back rotation smooth and lockup reliable.

A continuous cross-weld secures the connecting plate to the movable profile, simplifying assembly while improving flange rigidity and shape retention.

A horizontal motor-driven linkage lets theater seats recline on sloped floors while staying compact and keeping under-seat space clear for cleaning.

A slideable deck and toothed arms let one chair back pad move forward or backward to match different user figures and sitting postures.

A three-joint seat tilt linkage and catch elements simplify adjustment while improving crash load transfer and reducing seat weight.

A powered recliner shifts the seat back forward during motion, maintaining wall clearance and preventing rear contact in all positions.

Tapered end teeth and an inclined tooth plane help a seat recliner release ratchet meshing more smoothly while preserving locking strength.

A center-of-gravity-aligned seat lock lets users adjust and lock seat angle by body balance without standing up.

A telescopic cross-linking mechanism shifts the chair backrest forward or backward to support children at different growth stages.

A release finger and spring-loaded clutch let a vehicle seat backrest switch from fine inclination adjustment to rapid repositioning.

A rotatable, sliding seat lets recumbent stepper users match leg reach and transfer more easily while preventing unsafe track release.

An asymmetric lock-member layout and cam holding mechanism keep seat recliner locks fully disengaged, preventing half-locked operation.

Multiple pawls, teeth, and a cam disc lock or release seat-back rotation to give precise recline adjustment with a compact mechanism.

A dual-axis recliner, rivet, and latch arrangement lets the seat back fold smoothly while staying secure for better space management.

A radial flange keeps the reclining operating shaft aligned, preventing tilt under spring force and lowering the force needed to unlock.

A cam through-hole and matching spacer cylinder simplify reclining mechanism assembly by removing burring and press-fitting steps.

A screw-and-gear lift mechanism lets a booster seat change height as children grow, maintaining proper seat belt fit without replacement.

A screw-and-gear lift mechanism lets one booster seat adjust with child growth to keep the seat belt properly positioned.

An occupant-sensing cable-drive head restraint deploys for head support and retracts when the seat is empty to preserve rear visibility.

Radial and arcuate slots guide coupling pieces to deliver smooth, balanced chair tilting in slim seating without bulky locking mechanisms.

A floor-sliding front link lets a rear seat recline or stand upright, improving comfort, access, and storage in compact vehicles.
