The invention discloses an automobile headrest, comprising a shell, support arms, and a seat fixing part; the seat fixing part is arranged on the shell for fixing with the fixing rod on the automobile seat; each support arm is provided with a rotating shaft and a sliding shaft; the sliding shaft slides in a slideway inside the shell; one end of the sliding shaft is rotatably connected to the rotating shaft through a rotating structure; the support arm is slidably installed in the shell through the sliding shaft; the width between the support arms is adjusted laterally through the sliding shaft. The invention realizes the distance adjustment between the support arms through the lateral movement of the sliding shaft, realizes a better lateral adjustment of the sliding shaft through the design of the locking plate, the concave-convex part and the like, and realizes a better degree of freedom and comfort.

An automotive seat with headrest assembly includes a seatback, a headrest, and a pair of headrest supports adapted to support the headrest on the seatback, each of the headrest supports including a lower rod, an upper rod, and an absorption unit positioned between and interconnecting the lower rod and the upper rod, the absorption unit adapted to allow angular deflection of the upper rod relative to the lower rod when a bending force is applied to the upper and lower rods, and to hold the lower and upper rods in a deflected orientation when the bending force is removed from the upper and lower rods.

A seat assembly with an adjustable head restraint assembly capable of being adjusted based on an approximate stature or spatial location of an occupant in the seat assembly. A seat assembly may include a sensor in the seat to detect if an occupant is present. The sensor may include a plurality of bladders and pressure sensors, a radar system, or a neuro-monitoring sensor. The sensor may send a signal to a controller indicating the presence of an occupant. The controller may approximate the size and/or spatial location of the occupant and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to an in-use position. The controller may determine that an occupant is not present and send an adjustment signal to the head restraint adjustment mechanism to adjust the head restraint assembly to a non-use position.

A fully adjustable headrest with foldable head support wings for use in connection with furniture and with passenger vehicles such as aircraft, trains, and buses.

A headrest position adjusting device for a vehicle, may include a first motor mounted to a seatback frame; a first link connected to the first motor to be rotatable to a predetermined first angle in a leftward-rightward direction; a second motor mounted to the first link; a second link connected to the second motor to be rotatable to a predetermined angle in an upward-downward direction; a third motor mounted to the second link; a third link connected to the third motor to be rotatable with respect to a rotation axis of the third motor; and a headrest frame connected to the third link and mounted in a headrest pad.

A headrest device comprises: a headrest support that is pivotable relative to a backrest frame of a vehicle seat, about a first transverse axis; a headrest frame that is pivotable relative to the headrest support about a second transverse axis; and a tilt compensation device for the headrest frame. The compensation device comprises a connecting element in two parts that are pivotable relative to one another, and first and second pivotable guide pins respectively received in a first guide path in the headrest support and in a second guide path formed by the headrest frame. The second part of the connecting element is guided in translation relative to the headrest support in a direction perpendicular to the first axis.
