Abstract: 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.

Abstract: An adjustable headrest assembly including a mounting post for mounting the headrest assembly to a vertically adjustable tower. The headrest including an elongated body portion extending horizontally between first and second ends and defining a tubular opening for receiving a mounting post for securing the headrest to the tower. A cavity is integrally formed in the first end of the body portion and a ratchet mechanism is disposed in the cavity for pivoting the headrest in both the forward and rearward direction. The ratchet mechanism including a ratchet pivotally support by the mounting post and a rack having a plurality of rack teeth mounted along an arcuate path in the cavity of the headrest body. The assembly further including a tower cover including an expandable window portion connected between the tower and the seat back for automatically expanding coverage of the tower upon movement of the tower between a lower position and a raised position.
