A headrest can be pivoted between a use state and a retracted state. The headrest has a pivot shaft pivotally supported to an upper part of a back frame. Opening ends of the headrest frame are connected to the pivot shaft. A locking mechanism is provided on the pivot shaft between the ends of the headrest frame. The lock mechanism includes right and left lateral wall portions into which the pivot shaft is inserted. Right and left lateral plate portions are connected to the pivot shaft between the right and left lateral wall portions. The headrest frame is pivotally biased toward the retracted position by a pivot member biasing spring. The locking mechanism may have a columnar member. The columnar member may approach the pivot shaft while maintaining a parallel state with the pivot shaft.

The present invention relates to a headrest moving device, and more particularly, to a headrest moving device in which one end of a strap is connected to a member to which a first member is connected, the other end of the strap is drawn out of a headrest or a seat, a guide rod configured to guide the strap is provided on the member to which the first member is connected, and a latching rod configured to latch a portion between one end and the other end of the strap is provided on the first member so that locking can be released through the strap drawn to the outside of the headrest. Thus, a user can easily recognize a way to release the locking and the first member can be smoothly rotated since the strap is smoothly guided.

A method of activating a head restraint system in a vehicle for an occupant is provided. The method comprises providing a vehicle seat having a seat belt and a head restraint in the vehicle and detecting the occupant in the vehicle. The method further comprises actuating the seat head restraint of the vehicle seat to an in-use position if the seat belt is buckled. The method further includes providing an actuation signal to an electronic control module of the vehicle if the seat head restraint is actuated.

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.
