The present invention relates to a headrest for a vehicle, the headrest comprising: a fixed elevating unit installed at the top end of a seat backrest and capable of being raised; a fixing shaft fixed to the fixed elevating unit and extending in a horizontal direction; a moving frame installed on the fixing shaft and including a guide rail and an automatic power transfer unit, so as to move linearly forward and backward and rotate upward and downward; a coupling main body coupled in a state enclosing the moving frame, and moving together with the moving frame; and a manually operated unit enabling the moving frame to be manually adjusted on the coupling main body. The manually operated unit is characterized by including an operating switch for electrical control so as to be capable of controlling a current flowing to the automatic power transfer unit.

A headrest assembly according to an exemplary aspect of the present disclosure includes, among other things, a head restraint including a push-button and a lever rotatable by a pull cable. The head restraint is moveable from an upright position to a folded position by movement of the push-button or the lever. This disclosure also relates to a seat and a method of use.

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.

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.

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.

A seat assembly includes a five-bar linkage for moving the seat assembly between a plurality of positions in an automotive vehicle. A first link is rotatably coupled to a seat back at a second pivot point disposed coaxial to a first pivot point, and to a seat base defining a fifth link at a third pivot point. A second link extends axially between the first and second pivot points. A third link is defined by a lower seat back portion and a seat cushion and extends between the first pivot point and a fifth pivot point disposed adjacent a front portion of the seat cushion. A fourth link is rotatably coupled to the third link at the fifth pivot point and the seat base at a fourth pivot point. The seat assembly is capable of moving to both a pitched easy entry position and a stow flat to floor position.
