摘要： A vehicle seat including a seatback, and headrest including a shell member. A release mechanism is mounted to the shell member. The release mechanism selectively locks the headrest relative to the seatback. An actuator system extends between the seatback and the headrest. The actuator system includes a sleeve having a first end fixedly connected relative to the seatback, a second end fixedly connected relative to the headrest shell, and an intermediate portion defining a longitudinal length of the sleeve, and a cable extending through the sleeve. The cable has a first end section arranged in the seatback and a second end section coupled to the release mechanism. The longitudinal length of the sleeve includes a first dimension when the seatback is in an upright position and the longitudinal length has a second, longer dimension, when the seatback is in a folded configuration.

摘要： A turnable headrest includes a headrest body and a headrest rod. The headrest body is wrapped around and hinged to a horizontal rod of the headrest rod, and two vertical rods of the headrest rod are inserted into a seat. The turnable headrest further includes a fixed tooth, a torsion spring, a rotary tooth, and a reset tension spring. A headrest body locking portion, a headrest body rotary tooth portion, and a turned headrest body locking portion are disposed on the fixed tooth. A rotary tooth portion is disposed on the rotary tooth. When the rotary tooth portion is mated with the headrest body locking portion on the fixed tooth, the headrest body is locked at an initial use position. When the rotary tooth portion is mated with the headrest body rotary tooth portion on the fixed tooth, the headrest body is at a turnable position. When the rotary tooth portion is mated with the turned headrest body locking portion on the fixed tooth, the headrest body is locked at a flat position. The turnable headrest has advantages such as a strong self-locking ability, a small quantity of parts, a simple structure, and low costs.

摘要： This disclosure generally relates to a headrest assembly, seat, and a method of use. In the disclosure, a head restraint is moveable from an upright position to a folded position by movement of either the push-button or a lever. The disclosed arrangement provides two ways to fold a head restraint, and can further be integrated with another assembly, such as a seat back folding assembly. The disclosed arrangement is further configured to resist vibration, leading to a tighter, more stable design, which provides increased customer satisfaction.

摘要： An improvement to foldable headrests remote actuators by providing a tube mounted spring compensator to facilitate movement between a stowage position and an operating position. The spring compensator is inserted concentrically within the hollow tubes that support the adjustable headrests to boost or compensate for the lack of force routinely experienced under cold weather use or aging of materials. The spring compensator is positioned inside the headrest support tube to help pull the cable up through the seat when the seat and headrest are returned from a stowage position to a passenger seating position. The spring compensator inside the headrest support tube allows the use of a smaller torsion spring in the headrest and reduces the stress on the components in the mechanism.

摘要： An automotive head restraint apparatus includes a housing having a padded and upholstered exterior, the housing being rotatable about a lateral support tube that supports a lock plate having a lobe extending radially with a detent slot extending therein. A latch finger extends from a pivotable lock lever plate to releasably engage in the detent slot to latch the housing in the deployed position. A pull rod is secured to the lock lever plate, and is connected to a release lever arm at its other end. A shape memory alloy (SMA) wire loop is passed about a drive pulley that is supported by a reciprocally translatable slide. A drive arm extends from the slide to impinge on the release lever and raise the pull rod when the SMA wire loop is energized and contracted, thereby releasing the latch finger to rotate the housing to the retracted position.

摘要： A headrest assembly includes a pivot pin rotatably coupled to a support structure. A pivot member extends outward from a headrest body and is coupled to the pivot pin. A lock assembly is disposed about the pivot pin and is operable between a disengaged condition and an engaged condition. In the engaged condition, rotation of the pivot pin relative to the support structure is generally prevented. A pulley wheel is operable to rotate about the pivot pin from a first position to a second position to prompt the lock assembly to enter the disengaged condition.

摘要： Provided is a simple and compact headrest support device. The headrest support device (20) comprises a support member (22) coupled to a frame (2) of a seatback (1), and a headrest pillar structure including a pillar base portion (25) extending laterally and supported by the support member so as to be rotatable around an axial line of the pillar base portion, and a pair of pillar main body portions (26) extending substantially vertically from the pillar base portion substantially in parallel to each other in a laterally spaced apart relationship and connected to a headrest (24), wherein the support member is coupled to the frame at at least one coupling portion (34) disposed between the two pillar main body portions in front view in a headrest upright condition where the headrest is positioned above the seatback.
