Claim 9:
10. A system, comprising:
an adjustable headrest assembly, comprising:
a headrest center bracket;
a left vertical side plate track positioned at a left side of the headrest center bracket;
a left headrest side plate assembly comprising a left headrest side plate, the left headrest side plate assembly engaged with the left vertical side plate track, wherein the left headrest side plate is configured to move up and down relative to the left vertical side plate track based on the engagement of the left headrest side plate assembly with the left vertical side plate track;
a right vertical side plate track positioned at a right side of the headrest center bracket;
a right headrest side plate assembly comprising a right headrest side plate, the right headrest side plate assembly engaged with the right vertical side plate track, wherein the right headrest side plate is configured to move up and down relative to the right vertical side plate track based on the engagement of the right headrest side plate assembly with the right vertical side plate track; and
a mounting plate assembly comprising a mounting plate, the mounting plate positioned behind the headrest center bracket, wherein the headrest center bracket is configured to rotate about a fore-aft axis positioned at a central location of the headrest center bracket, the fore-aft axis extending laterally forward and aft between the mounting plate and the headrest center bracket, wherein the left headrest side plate and the right headrest side plate rotate with the headrest center bracket, wherein the mounting plate assembly further comprises a friction pivot assembly allowing the headrest center bracket to rotate relative to the mounting plate, wherein the friction pivot assembly comprises:
a rotational pin extending through and/or between the headrest center bracket and the mounting plate, the rotational pin allowing the headrest center bracket to rotate relative to the mounting plate;
a first washer positioned against the headrest center bracket and around the rotational pin;
a second washer positioned against the first washer and around the rotational pin;
a third washer positioned against the second washer and around the rotational pin;
a spring positioned against the third washer and positioned around the rotational pin;
a fourth washer positioned between the spring and the mounting plate and positioned around the rotational pin;
a fifth washer positioned against the mounting plate and around the rotational pin; and
an e-clip positioned against the fifth washer and at least partially around the rotational pin.
