1. A vehicle seat headrest system for use in a vehicle, the headrest system comprising:
- a headrest comprising a receiving face facing forward and at least one headrest support post extending downward for adjustable connection with the vehicle seat, wherein the headrest has a maximum width,a distal sensor assembly for detecting a head position of an occupant seated on the vehicle seat, the distal sensor assembly comprising;
a mount configured to be removably attached to the at least one headrest support post,a stem connected with the mount and projecting upward,a plurality of arms, each arm having a proximal end connected with the stem and extending lengthwise laterally from the proximal end to a distal end, andat least one head position sensor attached to the distal end of each of the plurality of arms for sensing the head position of the occupant,a control system in communication with the sensors to receive a communication of a sensed position of the occupant'"'"'s head and configured to send instructions to a headrest adjustment device to adjust a position of the headrest to accommodate the sensed position of the occupant'"'"'s head to ease movement of the occupant'"'"'s head in the event of a sudden change in velocity,wherein the distal end of the arms are spaced laterally outward relative to the maximum width of the headrest to minimize engagement with the occupant'"'"'s head while positioning the sensors for accurate sensing of the head position.
