Abstract

A head restraint may include a support structure with an opening, adjustable flexible elongated members, and an adjustment mechanism. The elongated members may be attached to the support structure, may span the opening in the support structure, and may be configured to support a user's head. The adjustment mechanism may be configured to at least one of automatically and/or manually adjust tension of at least portions of the elongated members spanning the opening.

First claim

What is claimed is:

1. A head restraint comprising:
a support structure with an opening;
adjustable flexible elongated members attached to the support structure, spanning the opening in the support structure, and configured to support a user's head in at least an adjustable comfort mode;
an adjustment mechanism configured to at least one of automatically or manually adjust tension of at least portions of the elongated members spanning the opening; and
an actuator that actuates the adjustment mechanism to adjust the tension of the elongated members,
wherein the actuator operates in the comfort mode to cause the adjustment mechanism to adjust the tension of the elongated members according to a desired tension for comfort, wherein the comfort mode corresponds to normal use of the head restraint.

2. The head restraint of claim 1 , further comprising at least one lighting device attached to the support structure.

3. The head restraint of claim 1 , wherein the elongated members are configured to support a back portion of the user's head.

4. The head restraint of claim 1 , wherein the actuator is configured to be manually activated to adjust the tension of the elongated members in the comfort mode.

5. The head restraint of claim 1 , wherein the actuator is configured to be electronically activated to adjust the tension of the elongated members in the comfort mode.

6. The head restraint of claim 1 , wherein the actuator operates automatically in a collision mode to cause the adjustment mechanism to change the tension of the elongated members to a collision tension when a collision is detected.

7. The head restraint of claim 1 , wherein air can flow from the opening to back sides of the elongated members and from the back sides of the elongated members to front sides of the elongated members, wherein the air is at least one of ambient air or air from an active airflow system.

8. The head restraint of claim 1 ,
wherein the actuator operates automatically in a collision mode to cause the adjustment mechanism to change the tension of the elongated members to a collision tension when a collision is detected.

9. The head restraint of claim 8 , wherein the desired tension for comfort in the comfort mode is less than the collision tension in the collision mode.

10. The head restraint of claim 8 , wherein the actuator is configured to return to the comfort mode from the collision mode after the collision is completed.

11. The head restraint of claim 1 , wherein the adjustment mechanism increases the tension of the elongated members by pulling at least one side of the elongated members toward the support structure and decreases the tension of the elongated members by releasing a portion of at least one side of the elongated members.

12. The head restraint of claim 1 , wherein the elongated members attach to and extend between two substantially vertical and opposing side portions of the support structure, wherein the elongated members are substantially horizontal.

13. The head restraint of claim 1 , further comprising trim extending along a front side of the elongated members, wherein the trim is attached to the support structure.

14. A head restraint comprising:
a support structure with an opening;
adjustable flexible elongated members attached to the support structure, spanning the opening in the support structure, and configured to support a user's head;
an adjustment mechanism configured to at least one of automatically or manually adjust tension of at least portions of the elongated members spanning the opening; and
an actuator that actuates the adjustment mechanism to adjust the tension of the elongated members,
wherein the actuator operates automatically in a collision mode to cause the adjustment mechanism to change the tension of the elongated members to a collision tension when a collision is detected,
wherein the actuator is actuated by a control unit that is configured to determine the collision tension based at least in part on a relative angle of a seat back to a seat cushion.
