A headrest for a seat may have a headrest body, a support element having a rod end, and a base support element. The base support element is connected to the headrest body and the height can be adjusted relative to the support element using same. The headrest may also have a locking element for locking the base support element in an adjusted height position on the support element. The locking element may have a locking region and an actuation region. The locking region extends perpendicular to a transverse extension direction of the base support element and may be detachably blocked in a locked position. The actuation region extends from the base support element in a vertical direction. By actuating the actuation region, the locking region can be moved away from the bearing opening. A seat having a headrest of this type is also provided.

A vehicle seat including a seat cushion, a seat back, a seat belt, and a seat belt retractor is provided. The vehicle seat includes: a seat back frame comprising: right and left side frames disposed at a distance away from each other in a lateral direction; an upper frame connecting upper end portions of the right side frame and the left side frame; a lower frame connecting lower end portions of the right side frame and the left side frame; and a connecting frame made of a pipe member and disposed at distances away from the right and left side frames and connecting the upper frame and the lower frame; and a first bracket by which the seat belt retractor is attached to the seat back frame. The first bracket is provided on the connecting frame at distances away from the upper frame and the lower frame.

Vehicle seat with seat cushion and seat back includes a seat frame, which comprises: first and second frames disposed at a distance away from each other in a predetermined direction; third frame connecting end portions of the first and second frames; fourth frame connecting another end portions of the first and second frames; and a connecting frame disposed at distances away from the first frame and second frame and connecting the third frame and fourth frame. The seat frame comprises: first pipe member having a U-shaped configuration and configured to form the first frame, the connecting frame, and part of the third frame by which the first frame and the connecting frame are connected; and second pipe member having a U-shaped configuration and configured to form the second frame, a remaining part of the third frame and the fourth frame, and connected to the first pipe member.

A headrest may have at least one headrest body, a base support element, on which the headrest body is arranged such that the height can be adjusted and it can be locked in a height position, and a retaining element, with which the headrest body is arranged in a height-adjustable manner on the base support element. The retaining element can be detachably blocked in the adjusted height position. The retaining element engages through the base support element, and the retaining element is connected to the headrest body on both sides of the base support element. The headrest may also have a locking element for locking and unlocking the retaining element in the adjusted height position. The retaining element is guided in a height-adjustable manner on the base support element. A motor vehicle seat may have the headrest.

The headrest may also have a locking element for locking and unlocking the retaining element in the adjusted height position. The retaining element is guided in a height-adjustable manner on the base support element. A motor vehicle seat may have the headrest.

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.

A head restraint assembly is provided with a head restraint frame mounted to a post for movement along the post for adjustment relative to a vehicle seat. The head restraint frame has a contact surface. A biasing member is mounted to the head restraint frame for movement relative to the head restraint frame to maintain the head restraint frame in a locked condition along the post. An actuation member is mounted to the head restraint frame for movement relative to the head restraint frame. The actuation member cooperates with the biasing member such that movement of the actuation member moves the biasing member, thereby disengaging the biasing member from the post to permit movement of the head restraint along the post such that the biasing member engages the contact surface in the second position to provide feedback to the user of an unlocked condition of the head restraint frame.

A headrest is provided including a movable unit that can be shifted to multiple positions in the front-rear direction in a normal mode. A headrest includes first and second headrest pillars, a stationary unit disposed between the first and second headrest pillars, a movable unit movable apart from or close to the stationary unit toward a front or rear direction, an X linkage connecting the stationary unit to the movable unit and including an inside linkage segment and an outside linkage segment rotatably connected each other at a central connecting intersection, and a front-rear locking mechanism including a lock receiver and a locking component engageable with the lock receiver, to lock or unlock the movable unit movable relative to the stationary unit toward the front or rear direction.

A headrest support having a hollow cylindrical shape and into which a headrest stay is inserted, is inserted into a bracket that has a hollow cylindrical shape and is fixed to a seat back frame. A protrusion, a tip end of which is a pivot center of the headrest support, formed such that a protrusion amount thereof increases in response to insertion of the headrest stay, is provided on an outer peripheral surface of this headrest support.

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.
