The invention relates to a self-reset adjusting mechanism, including: a mounting base; an adjusting member rotatably mounted on the mounting base; a first reset member mounted between the adjusting member and the mounting base; a limiting member rotatably mounted on the mounting base, the limiting member being provided with, corresponding to the adjusting member, a plurality of clamping tables at different heights, and the position of the adjusting member being adjusted by clamping the adjusting member on the clamping tables corresponding to the limiting member; and a second reset member mounted between the limiting member and the mounting base, when the limiting member is rotated to the limit position, the second reset member being deformed to produce an acting force in a direction the same as the rotation direction of the limiting member to cause the limiting member to be in the limit position, and in this case, the first reset member resetting the adjusting member and exerting a reset acting force on the limiting member, so that the second reset member is restored and the limiting member is reset. The self-reset adjusting mechanism of the invention simplifies a core mechanism of a headrest while ensuring the strength of the headrest, has a simple structure, occupies a small space, and has a large adjustment range and a high impact resistance strength.

The invention relates to a headrest for a vehicle seat, comprising a first part; a second part that is able to rotate with respect to the first part; and a control rod for the relative movement between the first part and the second part; wherein the second part comprises an arcuate opening for receiving the rod, the opening comprising cavities; and wherein the rod is movable between an adjustment position in which the rod does not prevent the relative rotational movement between the first part and the second part; and a locked position in which the rod is trapped inside one of the cavities of the opening, thus preventing relative rotational movement between the first part and the second part.

A headrest includes a stay having left and right legs; a headrest main body attached to the stay and able to rotate in a front-rear direction; a pair of elongated holes made in a bottom surface of the headrest main body and a pair of closing members arranged on the bottom surface of the headrest main body, covering the elongated holes, wherein each closing member includes a main plate and a sub-plate, the main plate has an insertion hole guiding one leg of the stay and moves in the front-rear direction as the main plate is rotated, and the sub-plate is provided, overlapping the main plate, and is able to move as the main plate moves; the main plate and the sub-plate may move as the headrest main body is rotated, while covering the elongated hole made in the bottom surface of the headrest main body.

Disclosed is a headrest fore-aft position adjuster including a displaceable body which receives load of an occupant's head and which displaces in a fore-aft direction with respect to a headrest pillar and a lock mechanism which locks and unlocks the displaceable body at a plurality of positions along the fore-aft direction, and the lock mechanism includes an engaging part which displaces in the fore-aft direction integrally with the displaceable body, a plurality of engaged part which is provided along a trajectory of the engaging part and which the engaging part is engaged with in a locked state and the engaging part is configured to engage with the engaged parts from a lateral position.

A headrest element may have a central supporting region and two lateral supporting regions. The lateral supporting regions may be pivotable with respect to the central supporting region about a side pivot axis, which may run at least substantially parallel to a supporting surface of the central supporting region, in such a manner that an angle of the supporting surfaces of the lateral supporting regions can in each case be adjusted variably with respect to the supporting surface of the central supporting region. The central supporting region and the lateral supporting regions may be jointly pivotable about a transverse pivot axis, which runs at least substantially perpendicular to the side pivot axes, in such a manner that an adjustment of the supporting regions in the longitudinal direction of the vehicle is possible. A headrest using the headrest element is also described.
