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 mounted 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, wherein the fixed locking member includes a pin mounted on the cross member,

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.

2. The head restraint assembly of claim 1 wherein the latch is mounted to slide on the cross member such that when the latch slides in a linear direction along the cross member, the latch moves from the first engaged latch position to the second released latched position.

3. The head restraint assembly of claim 1 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.

4. The head restraint assembly of claim 1 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.

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

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

7. 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.

8. The head restraint assembly of claim 1 wherein the actuator further comprises a slide button mounted to an outer surface of the head restraint such that sliding the slide button slides the latch from the first latch position to the second latch position.

9. The head restraint assembly of claim 8 wherein the slide button is mounted on a rearward surface of the head restraint, opposite to a contact surface.

10. 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.

11. 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.

12. 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 slide latch mounted to slide on the cross member to a first latch position engaged with the locking member and slide linearly in a lateral direction along the cross member to a second latch position released from the locking member; and

an actuator arm pivotally supported by the head restraint, wherein pivoting of the actuator arm slides 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.

13. The head restraint assembly of claim 12 wherein the cross member further comprises at least one terminal end adapted to be mounted within the vehicle.

18. The head restraint assembly of claim 12 further comprising a slide button mounted on an outer surface of the head restraint and being connected to the actuator arm such that actuating the slide button actuator pivots the actuator arm thereby sliding the latch to the second latch position and releases the latch from the locking member for permitting movement of the head restraint.

19. The head restraint assembly of claim 12 further comprising a slide button mounted on an outer surface of the head restraint and being connected to the actuator arm, wherein the slide button slides in a direction parallel to the outer surface of the head restraint.

20. The head restraint assembly of claim 12 wherein the locking member includes a pin, and 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.

14. A head restraint assembly comprising:

a lateral cross member adapted to be mount within a vehicle;

a head restraint pivotally supported by the cross member, such that the head restraint pivots about a lateral axis of the cross member in order to move the head restraint between an upright position and a stowed position;

a locking member mounted within the head restraint;

a latch mounted on the cross member, the latch movable linearly between at least a first latch position where the latch is engaged with the locking member and a second latch position where the latch is released from the locking member; and

a slide button actuator mounted on an outer surface of the head restraint, the slide button actuator being connected to the latch such that actuating the slide button actuator moves the latch to the second latch position and releases the latch from the locking member for permitting movement of the head restraint from the upright position to the stowed position,

wherein the latch slides linearly in a lateral direction along the cross member.

15. The head restraint assembly of claim 14 wherein the slide button is mounted on a rearward surface of head restraint opposite a contact surface.

16. The head restraint assembly of claim 14 further comprising an actuator arm pivotally mounted within the head restraint and connecting the slide button actuator and the latch.

17. The head restraint assembly of claim 16 wherein the slide button actuator includes an elongated bar which engages an aperture formed in the actuator arm.
