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.

A vehicle head restraint assembly includes a base portion coupleable to a vehicle seat back, the base portion including a cross member portion. Also included is a head restraint operatively coupled to the cross member portion and rotatable about the cross member portion. Further included is a helical drive assembly for translating the head restraint during rotation of the head restraint.

A head restraint assembly for a seat, the assembly including: At least one support for mounting a bun assembly above the seat back; a bun assembly including a core portion, the core portion having integral first bearing surfaces; a stationary hub mounted on the at least one support, the stationary hub disposed at least substantially within the core portion and pivotally supporting the core portion via the integral first bearing surfaces; and a lock pivotally supported within the core portion. The lock is selectively pivotally moveable between positions of engagement with, and disengagement from, the stationary hub. The position of engagement is characterized in that the core portion is fixed relative to the stationary hub and at least one support, and the position of disengagement is characterized in that the core portion is pivotally moveable relative to the stationary hub and at least one support.

Provided is a simple and compact headrest support device. The headrest support device (20) comprises a support member (22) coupled to a frame (2) of a seatback (1), and a headrest pillar structure including a pillar base portion (25) extending laterally and supported by the support member so as to be rotatable around an axial line of the pillar base portion, and a pair of pillar main body portions (26) extending substantially vertically from the pillar base portion substantially in parallel to each other in a laterally spaced apart relationship and connected to a headrest (24), wherein the support member is coupled to the frame at at least one coupling portion (34) disposed between the two pillar main body portions in front view in a headrest upright condition where the headrest is positioned above the seatback.

The invention relates to a headrest for a seat, in particular for a vehicle seat, comprising a head support (11) that can be supported on a vehicle seat by a mounting assembly (13), wherein the mounting assembly (13) comprises a linkage (18) comprising a first holding element (16) on the head support (11), and a second holding element (17) fixed to the seat part, that the first holding element (16) and the second holding element (17) are connected to one another by guides (19a, 19b, 20a, 20b) in such a way that at least one four-pivot linkage (27a, 27b) is formed that can shift the head support (13) relative to the vehicle seat between a front position moved forward toward the head of a seat occupant, and a rear position moved backward.

Provided is a headrest folding apparatus. An oblique face is formed on a support for supporting a headrest. When the headrest is in an upright position, the oblique face comes into contact with a first member. The headrest folding apparatus prevents a loose gap from occurring in an upright state, simplifies components to be made compact, and allows a seat to be easily assembled and a manufacturing cost to be cut down.
