## Abstract

A headrest includes a first assembly. The first assembly includes a first threaded shaft that is integrated with a first magnetized rotor of a first motor. Rotation of the first motor and the first threaded shaft results in vertical translation of a first threaded nut carrier such that a height of the headrest is adjusted.

## Claims

### Claim 1

A headrest, comprising:
a main body comprising a housing;
at least one headrest post for supporting the headrest on a backrest;
a first assembly comprising a mounting bracket and a first threaded shaft that is integrated with a first magnetized rotor of a first motor, wherein the mounting bracket is fixedly mounted on the at least one headrest post and the first motor is mounted on the mounting bracket, wherein rotation of the first motor and the first threaded shaft results in vertical translation of a first threaded nut carrier such that a height of the headrest is adjusted; and
a second assembly comprising a guide bracket and a second threaded shaft that is integrated with a second magnetized rotor of a second motor, wherein the guide bracket is slidably supported on the at least one headrest post and the second motor is mounted on the guide bracket, wherein rotation of the second motor and the second threaded shaft results in horizontal translation of a second threaded nut carrier such that a horizontal position of the headrest is adjusted, and wherein the first and second assemblies are completely contained in the housing.

### Claim 2 (depends on 1)

The headrest of claim 1, wherein the second assembly is coupled to the first threaded nut carrier.

### Claim 3 (depends on 2)

The headrest of claim 2, wherein the second assembly is translated with the first threaded nut carrier as the first assembly adjusts the height of the headrest.

### Claim 4 (depends on 1)

The headrest of claim 1, wherein the second threaded nut carrier is integrated with a bun assembly of the headrest.

### Claim 5 (depends on 1)

The headrest of claim 1, wherein the first and second motors are brushless motors.

### Claim 6 (depends on 1)

The headrest of claim 1, wherein the headrest is provided as a component of a seating assembly.

### Claim 7 (depends on 6)

The headrest of claim 6, wherein the seating assembly is installed in a vehicle.

### Claim 8

A vehicle, comprising:
a seating assembly having a headrest, wherein the headrest comprises:
a main body comprising a housing;
at least one headrest post for supporting the headrest on a backrest;
a first assembly comprising a mounting bracket and a first threaded shaft that is integrated with a first magnetized rotor of a first motor, wherein the mounting bracket is fixedly mounted on the at least one headrest post and the first motor is mounted on the mounting bracket, wherein rotation of the first motor and the first threaded shaft results in vertical translation of a first threaded nut carrier such that a height of the headrest is adjusted; and
a second assembly comprising a guide bracket and a second threaded shaft that is integrated with a second magnetized rotor of a second motor, wherein the guide bracket is slidably supported on the at least one headrest post and the second motor is mounted on the guide bracket, wherein rotation of the second motor and the second threaded shaft results in horizontal translation of a second threaded nut carrier such that a horizontal position of the headrest is adjusted, and wherein the first and second assemblies are completely contained in the housing.

### Claim 9 (depends on 8)

The headrest of claim 8, wherein the second assembly is coupled to the first threaded nut carrier.

### Claim 10 (depends on 9)

The headrest of claim 9, wherein the second assembly is translated with the first threaded nut carrier as the first assembly adjusts the height of the headrest.

### Claim 11 (depends on 8)

The headrest of claim 8, wherein the second threaded nut carrier is integrated with a bun assembly of the headrest.

### Claim 12 (depends on 8)

The headrest of claim 8, wherein the first second motors are brushless motors.
