Abstract

A vehicle head restraint assembly is provided with a cross member. A head restraint is supported by the cross member. A fixed locking member is mounted within the head restraint. A latch is moveably mounted on the cross member at a first latch position and at a second latch position. An actuator is mounted within the head restraint to move the latch between the first latch position and the second latch position. The head restraint is pivotable when the latch is in the second latch position. Another vehicle head restraint assembly is provided with a lateral support rod and a head restraint pivotally mounted thereon. A locking member is pivotally mounted within the head restraint. A latch is mounted on the support rod. An actuator disengages the locking member from the latch. A biasing member pivots the head restraint upon disengagement of the latch and the locking member.

Claims

1. A head restraint assembly comprising:

a cross member adapted to be mount within a vehicle;

a head restraint supported by the cross member;

a fixed locking member mounted within the head restraint;

a latch moveably mounted on the cross member at a first latch position engaged with the fixed locking member and at a second latch position released from the fixed locking member; and

an actuator provided proximate the latch to move the latch between the first latch position and the second latch position;

wherein the head restraint is pivotable about the cross member when the latch is in the second latch position.

2. The head restraint assembly of claim 1 further comprising a motor connected to the actuator such that the motor moves the actuator to translate the latch from the first latch position to the second latch position;

wherein movement of the actuator is also initiated by displacing a cable in communication therewith, by movement of a push rod, and by movement of a push button provided externally to the head restraint.

3. The head restraint assembly of claim 1 wherein the fixed locking member further comprises a lock plate.

4. The head restraint assembly of claim 1 wherein the fixed locking member further comprises a pin mounted on the cross member.

5. The head restraint assembly of claim 4 wherein the latch has a release slot that allows movement of the latch relative to the pin such that when the latch is in the second latch position, the head restraint pivots about the cross member.

6. The head restraint assembly of claim 5 further comprising a biasing member mounted to the head restraint and the latch to bias the latch to allow the latch to move relative to the pin.

7. The head restraint assembly of claim 5 wherein the release slot moves relative to the pin in a first direction as the latch moves along the cross member and the release slot moves relative to the pin in a second direction as the head restraint pivots about the cross member.

8. The head restraint assembly of claim 1 further comprising one or more bushings mounted between the head restraint and the cross member thereby allowing rotation of the head restraint when the latch is in the second latch position.

9. The head restraint assembly of claim 1 wherein movement of the actuator is initiated by displacing a cable in communication therewith.

10. The head restraint assembly of claim 1 wherein movement of the actuator is initiated by movement of a push rod.

11. The head restraint assembly of claim 10 wherein the push rod is connected to an armature such that the push rod translates the armature to pivot the actuator to disengage the latch from the locking member.

12. The head restraint assembly of claim 1 wherein the actuator further comprises a push button provided externally to the head restraint such that pushing the push button translates the latch from the first latch position to the second latch position.

13. The head restraint assembly of claim 1 further comprising a motor connected to the actuator such that the motor moves the actuator to translate the latch from the first latch position to the second latch position.

14. The head restraint assembly of claim 1 further comprising a biasing member to move the head restraint from a first head restraint position to a second head restraint position when the latch is in the second latch position.

15. The head restraint assembly of claim 1 further comprising a damper mechanism provided within the head restraint to dampen movement of the head restraint between the first head restraint position to a second head restraint position.

16. The head restraint assembly of claim 1 further comprising a pair of bracket members to mount the cross member within the vehicle;

wherein the cross member further comprises at least one hollow terminal end adapted to be mount within the vehicle.

17. The head restraint assembly of claim 1 wherein the head restraint further comprises a first shell and a second shell.

18. A head restraint assembly comprising:

a cross member adapted to be mount within a vehicle;

a head restraint supported by the cross member;

a locking member mounted within the head restraint;

a latch moveably mounted on the cross member at a first latch position engaged with the fixed locking member and at a second latch position released from the fixed locking member; and

an actuator pivotally supported by the head restraint to move the latch between the first latch position and the second latch position;

wherein the head restraint is pivotable about the cross member when the latch is in the second latch position.

19. The head restraint assembly of claim 18 wherein the cross member further comprises at least one terminal end adapted to be mount within the vehicle.

20. A vehicle head restraint assembly comprising:

a lateral support rod having at least one terminal end adapted to be mount within a vehicle, the lateral support rod having a lateral axis;

a head restraint pivotally mounted on the lateral support rod such that the head restraint pivots about the lateral axis relative to the lateral support rod;

a biasing member mounted on the lateral support rod to bias the head restraint relative to the lateral support rod;

a locking member pivotally mounted within the head restraint;

a latch mounted on the lateral support rod for engagement and disengagement from the locking member such the biasing member pivots the head restraint about the lateral axis relative to the lateral support rod upon disengagement of the latch and the locking member; and

an actuator provided proximate the locking member to pivot the locking member from engagement to disengagement with the latch.
