Foldable headrest assembly
First Claim
1. A foldable headrest assembly for a seat comprising:
- a post for engagement with an upper portion of the seat;
a frame extending between a first end and a second end with said first end rotatably supported by said post for selective rotation of said frame relative to said post about a first axis;
a latch moveably supported by said first end of said frame;
a release pin mounted to said latch for movement with said latch;
a release mechanism coupled to said latch for moving said latch and said release pin between a locked position with said latch engaging said post to prevent rotation of said frame about the first axis and an unlocked position with said latch disengaged from said post to allow rotation of said frame about the first axis; and
an inertia lock rotatably coupled to said frame for rotation from a neutral position to a triggered position in response to deceleration of said frame and defining a stop slot dimensioned to catch said release pin in the triggered position and prevent the movement of said latch from the locked position to the unlocked position.

Abstract
A foldable headrest assembly for a seat includes a pair of posts engaged with an upper portion of the seat and a frame rotatably supported by the posts. A latch is moveably supported by the frame and includes a release pin. A release mechanism is coupled to the latch for moving the latch from a locked position preventing rotation of the frame relative to the posts to an unlocked position allowing rotation of the frame relative to the posts. The assembly further includes an inertia lock rotatably coupled to the frame. The inertia lock defines a stop slot corresponding to the release pin. In response to deceleration of the frame, e.g., resulting from a collision of the vehicle, the inertia lock rotates to a triggered position whereby the stop slot receives the release pin and limits movement of the release pin thereby maintaining the latch in the locked position.
