This disclosure generally relates to a headrest assembly for a seat in a vehicle. In particular, the headrest assembly includes a locking arrangement that reduces, if not completely eliminates, buzz, squeak, and rattle (BSR). An exemplary headrest assembly includes, among other things, a rod including a recess and which is configured to connect the headrest assembly to a seat back. The headrest assembly also includes a head restraint having a locking portion configured to selectively engage the recess to set a vertical position of the head restraint relative to the rod. Further, at least one of the recess and the locking portion is tapered. Tapering the recess and/or the locking portion ensures that there will be two opposed points of contact between the recess and the locking portion, thereby reducing, if not eliminating, BSR between the two elements.

An apparatus of adjusting height of a headrest for a motor vehicle is provided. By forming the headrest with two divided parts, a rear portion fastened to a seatback by a stay and a front portion assembled to the rear portion movably in an up and down direction, the apparatus allows an occupant to adjust the height of the front portion according to his or her body size or preference, and thus is configured for comfortably supporting the head or neck portion of the occupant with the front portion regardless of the body size of the occupant.

A backrest of a vehicle seat comprises a backrest armature, at least one central upholstery module and two side upholstery modules each arranged on a respective side of the central upholstery module. Each of the at least three upholstery modules is fixed to the backrest armature independently of the other two upholstery modules.

A backrest of a vehicle seat includes an armature and an upholstery fixed to the armature. The upholstery has a slit for accommodating a headrest support rod by relative movement of the upholstery with respect to the armature in a longitudinal direction of the vehicle seat. The backrest further includes first and second trim elements. Each trim element forms a notch. The notches of the first and second trim elements define a passage for a headrest support rod. The second trim element partially covers the slit in the upholstery. The first and/or the second trim elements is/are in contact with the upholstery.

A device for adjusting a position of a headrest for a vehicle includes: a stay mounted on a seatback frame; a main frame including a rotation guide hole, inserted into and mounted on the stay, and configured to ascend or descend along the stay; an elevation device mounted on the main frame and the stay, and configured to allow the main frame to ascend or descend along the stay; a rotating frame including a first end portion inserted into the stay and configured to ascend or descend along the stay, and a second end portion extending toward the rotation guide hole of the main frame; a rotating device mounted on the rotating frame and the rotation guide hole of the main frame, and configured to rotate the rotating frame along the rotation guide hole; and a headrest frame assembled to the rotating frame.

The present disclosure relates to a vehicle seat cover designated for a detachable attachment to a headrest of a vehicle seat. The vehicle seat cover comprises a pliable first layer with a first recess and a pliable second layer with a first recess, the recesses being configured for accommodating the headrest rod. The recesses each have an edge opening. In the state of the vehicle seat cover attached to the headrest rod one edge opening is partially or completely covered by an edge which limits the other recess.
