The invention relates to a motor vehicle seat for motor vehicles comprising an adjustment device for a backrest head adjustment, the motor vehicle seat having a backrest, which has a backrest frame as the first component of the backrest head adjustment and a backrest head as the second component of the backrest head adjustment, and an actuator. The backrest head is pivotably connected to the backrest frame and the actuator has a driving element and a movable element, the actuator being connected to the backrest frame and the backrest head and it being possible to carry out a linear movement by means of the actuator. The driving element of the actuator is rigidly connected to the backrest frame or backrest head and the movable element of the actuator has a guide element which engages in a guide arranged on the backrest frame or backrest head.

A headrest assembly for use in a vehicle seat. The headrest assembly includes one or more support arms that are connected to a seatback frame. An adjustable connection assembly connects at least a portion of the one or more support arms to at least a portion of the headrest body. The adjustable connection assembly allows the head rest body to move in a forward and rearward direction, to move in an up and down direction, and/or to pivot relative to the seatback frame of the vehicle seat.

Disclosed is a positioning device for a vehicular seat that is configured to enable a driver or occupant to adjust a position of a headrest according to a body type or posture, so that the driver can drive a vehicle in a comfortable position, as well as minimizing an injury to cervical vertebrae in a car accident.
