Abstract

A headrest assembly is provided herein. A headrest is coupled to a seatback. The seatback includes a housing. The headrest is movable between a first position wherein the headrest is exposed above the seatback, and a second position wherein the headrest is concealed within the housing. A top of the headrest is flush with a top of the seatback while in the second position.

First claim

What is claimed is:

1. A headrest assembly, comprising:
a headrest coupled to a seatback;
the seatback comprising a housing;
the headrest movable between a first position wherein the headrest is exposed above the seatback, and a second position wherein the headrest is concealed within the housing;
wherein a pushing or pulling force exerted on the headrest enables adjustment of the headrest between first and second positions; and
a rail disposed within the seatback and operably coupled to the headrest, wherein the headrest comprises a rod movably coupled to the rail, the pushing or pulling force resulting in translational displacement of the rod about the rail to enable adjustment of the headrest between the first and second positions.

2. The headrest assembly of claim 1 , further comprising a locking engagement coupled to the rod and configured to engage one of a plurality of notches extending a length of the rail to hold the position of the headrest.

3. The headrest assembly of claim 2 , further comprising a cable coupled to both the adjustment device and locking engagement and configured to disengage the locking engagement from one of the plurality of notches when the adjustment device is engaged.

4. The headrest assembly of claim 2 , wherein each of the plurality of notches is associated with a unique position of the headrest.

5. A headrest assembly, comprising:
a headrest coupled to a seatback, the seatback comprising a housing;
a bracket supporting the headrest and disposed within the seatback;
the headrest movable between a first position wherein the headrest is exposed above the seatback, and a second position wherein the headrest is concealed within the housing; and
an actuator configured to raise or lower the bracket to adjust the headrest between the first and second positions, wherein the bracket is movably coupled to a frame disposed within the seatback, and wherein the actuator is configured to rotate a screw coupled to the bracket, and rotation of the screw causes the bracket to translate about the frame and an adjustment of the headrest position.

6. The headrest assembly of claim 5 , wherein at least one arm couples the headrest to the bracket.

7. The headrest assembly of claim 5 , wherein the actuator is configured to move the bracket vertically about the frame to adjust the headrest position.

8. The bracket assembly of claim 5 , further comprising a block at one end of the screw configured to stop rotation of the screw when the block makes contact with the bracket.

9. A headrest assembly, comprising:
a headrest coupled to a seatback, the seatback comprising a housing;
a bracket supporting the headrest and disposed within the seatback;
the headrest movable between a first position wherein the headrest is exposed above the seatback, and a second position wherein the headrest is concealed within the housing;
an actuator configured to raise or lower the bracket to adjust the headrest between the first and second positions; and
a pressure sensor configured to send a signal to the actuator to adjust the position of the headrest when an occupant is in a vehicle seat.

10. The headrest assembly of claim 9 , wherein the pressure sensor is configured to send a signal to the actuator to adjust the position of the headrest to the second position when there is no occupant in the vehicle seat.

11. The headrest assembly of claim 9 , wherein the actuator is programmed to adjust the headrest to a specific position when the pressure sensor detects an occupant in the vehicle seat.
