1. An articulating head restraint comprising:
- a bracket, the bracket having a slot;
an armature contained within the bracket, the armature having a first armature end and a second armature end, and the first armature end resides within a bracket hole and the second armature end resides within a slave bracket hole;
a cam having a lock acumination and a stop acumination, the cam fixedly attached to the armature;
a slide attached to the bracket, the slide moveable within the slot to a locked position so that, when the slide is in the locked position, the lock acumination is in contact with the slide thereby preventing rotation of the armature, where the slide has an unlocked position such that when the slide is in the unlocked position, the lock acumination is not in contact with the slide;
a torsion spring circumferentially disposed about the armature and configured so as to apply a torque on the armature tending to move the armature to a stowed position;
at least one rod for attaching a bun;
a coil spring attached to the bracket and to the slide and configured so as to tend to pull the slide to the locked position; and
a cable attached to the slide and configured such that a force applied to the cable will tend to pull the slide to the unlocked position.

Abstract
An articulating head restraint includes an armature with a cam. The cam has a lock acumination and a stop acumination. The armature fits within a structure composed of a bracket and a slave bracket. A slide, which is attached to a cable, rides within a slot on the bracket. When the slide is in the locked position, the lock acumination of the cam presses against the slide, restraining movement of the slide. When sufficient force is applied to the cable, the slide moves within the slot to an unlocked position. A torsion spring wrapped around the armature causes the armature to rotate to a stowed position.

11. An articulating head restraint comprising:
-
an armature having a first armature end and a second armature end;
a torsion spring circumferentially disposed about the armature;
a bracket, the bracket having a slot and a bracket hole;
a slave bracket, the slave bracket having a slave bracket hole;
a cam attached to the armature, the cam having a lock acumination and a stop acumination;
a slide moveable within the slot from a locked position to an unlocked position, such that when the slide is in the locked position, the lock acumination is in contact with the slide such that the cam is prohibited from rotating, thereby preventing the armature from rotating;
a coil spring, the coil spring tending to move the slide to the locked position;
a cable, the cable attached to the slide such that when a force is applied to the cable, the slide tends to move to the unlocked position; and
a stop rivet for prohibiting motion of the armature, and the stop acumination is arranged to contact the stop rivet to prohibit motion of the armature. - View Dependent Claims (12, 13)

14. An articulating vehicle head restraint comprising:
-
a bracket;
an armature contained within the bracket, the armature having a first end;
a cam having a lock acumination, the cam fixedly attached to the armature;
a moveable locking element for engagement with the lock acumination to prevent rotation of the armature, a torsion spring circumferentially disposed about the armature;
a rod for attaching a bun, the rod directly attached to the armature; and
a second spring attached to the bracket and to the moveable locking element for urging the moveable locking element into engagement with the lock acumination. - View Dependent Claims (15, 16, 17, 18, 19)
