    Abstract: Systems and methods are provided for improved and intuitive adjustment of a vehicle headrest. A vehicle headrest adjustment system may include touch sensors and/or motion sensors to determine a driver or passenger intends to adjust a vehicle headrest. Upon detection of touch consistent with intent to adjust a vehicle headrest and/or a hand gesture consistent with intent to adjust a vehicle headrest, a system may unlock a vehicle headrest. A driver or passenger may move the unlocked vehicle headrest into the desired position. Upon detection of a condition indicating the driver or passenger is finished and/or upon a set period of time elapsing, the system may re-lock the vehicle headrest into place. A vehicle headrest adjustment system may also include a power-assist function. The power-assist function may include motors and force sensors to assist a driver or passenger in moving a vehicle headrest into a desired position.

    Abstract: A seat assembly includes a seat bottom and a seat back extending along a first axis and coupled to the seat bottom for receiving a vehicle occupant. The seat back includes a seat back frame with at least a first cross-member extending parallel to a second axis, perpendicular to the first axis. The seat assembly further includes a head restraint assembly with a head restraint and at least one head restraint post that supports the head restraint on the seat back. The seat assembly further includes a motor at least partially housed within the first cross-member of the seat back frame and configured to selectively generate an output torque. The seat assembly further includes a drive assembly coupled to the motor and the head restraint assembly to receive the output torque and, in response, translate the head restraint in at least one direction parallel to the first axis.

    Abstract: A vehicle seat is provided. The vehicle seat comprises at least one backrest which is pivotally mounted relative to a seating surface of the vehicle seat; a backrest adjusting mechanism and a drive for pivoting the backrest; and at least one headrest on the backrest, which by means of a headrest adjusting mechanism is adjustable in its height relative to the backrest at least along a direction of longitudinal extension of the backrest. It is provided that beside the backrest adjusting mechanism the drive is coupled with the headrest adjusting mechanism, in order to simultaneously transmit an adjustment force to the headrest adjusting mechanism when the backrest is pivoted in at least one backrest adjustment direction. In addition, there is proposed a backrest module with a drive which beside a backrest adjusting mechanism is coupled with a headrest adjusting mechanism.

    Abstract: A powered head restraint includes a base bracket with elongate supports that are configured to easily engage a seatback guide during vehicle assembly and to provide an electrical connection for adjustment actuation of the head restraint. A first electrical connector is fixedly attached to the elongate support of the head restraint. A second electrical connector is operably connected to an upper portion of the seatback such that engagement of the elongate support with a support guide occurs simultaneously with engagement of the first electrical connector with the second electrical connector.
