This disclosure generally relates to a bushing arrangement for a headrest assembly of a seat in a vehicle. In one example of the present disclosure, the headrest assembly includes a rod configured to connect the headrest assembly to a seat back, and a head restraint. The head restraint includes a bushing configured to contact the rod and a spring configured to impart a force on an outer surface of the bushing. This arrangement allows a user to smoothly raise and lower the head restraint, and increases the stability of the head restraint relative to the rod.

The present invention discloses a headrest height adjustment mechanism for child safety seats, which comprises a backrest (1), a headrest (2) and an adjustment device (3); wherein the adjustment device comprises a limiting block (31), a spring (33), an adjustment bar (32) capable of sliding up and down inside the mounting chamber (21); the limiting block (31) has a blocking portion (311); the adjustment bar (32) has a driving portion (321); the spring (33) is disposed between the adjustment bar (32) and the headrest (2) and enables the adjustment bar (32) to have a trend to slide downward. Compared with the prior art, the headrest height adjustment mechanism for child safety seats is convenient for operation and has high reliability of locking and unlocking.

A headrest adjustment mechanism is provided and includes a housing receptive of a rod and gripping jaws disposable in the housing to grip the rod such that the rod is securable and primarily adjustable in a height-wise dimension defined along a longitudinal axis of the rod and such that the rod is movable and pivotable in lateral dimensions defined transversely relative to the longitudinal axis of the rod.

A head restraint for a seat being adjustable in a vertical direction, and angularly adjustable with regard to lateral portions of the head restraint. A mechanism providing this adjustability is a linear and rotational locking mechanism with a shaft and a slide. The slide is selectively slidably and rotatably mounted on the shaft. The slide has a locked state which linearly and rotationally fixes the slide on, and with respect to, the shaft. The slide has a release state where the slide is linearly and rotatably movable on the shaft. The slide is fixable in a plurality of linear and rotational positions on the shaft in the locked state. The number of linear and rotational positions on the shaft is considered infinite since for all practical purposes, the slide is not restricted to individual discrete positions, but is continuously adjustable to practically any linear and rotational position.

A headrest frame for a seat is disclosed. In various embodiments, the headrest frame includes a main body portion having a stowed length; a top portion configured to assume a stowed position and a deployed position with respect to the main body portion, the deployed position defining a deployed length greater than the stowed length; and a deployment mechanism configured to urge the top portion into the deployed position from the stowed position.

A head restraint assembly includes a base portion including a first post portion extending in a vertical direction. Also included is a head restraint operatively coupled to the base portion. Further included is a housing comprising a front shell and a rear shell. Yet further included is a lock slide manually moveable between a locked condition and an unlocked condition. Also included is at least one armature biasing member surrounding a portion of the base portion and biasing the base portion to be in constant contact with the front shell. Further included is at least one journal friction spring disposed within at least one of the front shell and the rear shell to control a manual adjustment effort, the at least one armature biasing member and the at least one journal friction spring biasing the housing in the same direction.
