A sliding driving member links headrest height and side wing unfolding, simplifying child seat adjustment for different body sizes.

A motorized headrest uses sensors and controller feedback to align an occupant's head with vehicle loudspeakers for better listening.

A non-linear vibration isolator between headrest structures creates quasi-zero stiffness to cut seat vibration transfer and improve comfort.

A bulging center and hollow cushion section protect the user's head while cutting headrest component count and manufacturing cost.

A hollow cushion with a central bulging surface improves head protection in work vehicle headrests while cutting part count and manufacturing cost.

A two-stage reclining seat and stowable headrest-pillow create a flat camping surface while avoiding separate headrest storage.

A single driving member links headrest height and side wing unfolding, simplifying child car seat fit adjustment for different body sizes.

A strip plate locks the headrest cover into an insert opening, removing the outer cover while preserving appearance and simplifying molding.

A two-step headrest release unlocks the safety lock first, preventing accidental height adjustment in child support devices.

An extendable neck support cushion locks in position to give vehicle occupants adjustable neck support while staying compact when retracted.

Sliding and spring-clamped side pillows adapt to different head deflections while keeping seat headrest adjustment practical and secure.

A plastic headrest with longitudinal rib chambers cuts mass while preserving load-bearing strength, comfort, and safety in vehicle seats.

A closed wave-profile cushion support holds the head in place during impact while absorbing force with a lightweight, robust structure.

Spring-clip friction hinges let headrest side panels pivot and hold position, improving occupant fit, comfort, and impact support.

Integrated locking, guide rail, and front/rear modules enable one-handed four-direction headrest adjustment while concealing exposed mechanics.

Air pockets fine-tune vehicle headrest wing frame angles, replacing complex mechanisms with precise pneumatic support and comfort.

Deployable fingers, movable legs, and a locking mechanism let a vehicle holder securely fit and retain electronic devices of varying sizes.

A tension spring and pivot link keep a powered head restraint moving smoothly while reducing guide-gap vibration, noise, and tolerance issues.

A motor-driven lead screw moves only the front headrest section, enabling fine vertical adjustment with lower power use and better neck protection.

A polyurethane film coated in the mold creates a smooth, robust seat cushion surface while keeping recycled foam or fiber padding low cost.

A movable latch element follows headrest rod rotation to prevent disengagement on impact and keep the rod securely positioned.

Cutting teeth into the headrest tube end and pressing them inward forms a chamfer in one pass while preventing swelling and diameter change.

A motor-driven slider and rotation link replace gap-prone X-links to deliver accurate headrest positioning with lower noise and steadier support.

A removable forehead mount stabilizes the head on the spine for comfortable upright rest without strapping the user to the seat.

Long-range wireless power lets vehicle seats move freely while obstacle detection interrupts transmission to protect passengers.

Occipital bone support from the sides and obliquely upward stabilizes head motion during acceleration without complex active seat mechanisms.

A pivoting tooth-and-spring mechanism lets a vehicle headrest adjust and lock securely without hard-to-reach release buttons.

A sliding linkage lets the seat move into storage without jamming nearby parts while still allowing seatback angle adjustment.

A safety lock and press-pull sequence keep a child seat headrest locked during height adjustment, reducing accidental release.

A cover injection point placed away from the tension member helps headrest foam fill evenly, preventing hard spots and member damage.

A retractable front end and rotary base let the seat turn sideways for easier child access without colliding with the vehicle door.

Mesh covering and internal openings improve rear passenger forward visibility while preserving headrest comfort, rigidity, and impact absorption.
