Abstract: An automotive seat assembly is provided including a seatback and a motion translation element pivotably mounted within. The motion translation element includes a back engagement portion, movable between a back engagement stable position and a back intrusion position, and a translation portion, movable from a translation stable position to a translation actuated position in response to the back engagement portion movement. A intermediary element is rotatably attached to the translation portion, such that it is moved between an intermediary stable position and an intermediary actuated position. The intermediary element is additionally movable between a disengagement position and a engagement position. A momentum cam is utilized to move the intermediary element into the engagement position during vehicle impact. A trigger arm is positioned within said seatback and engages the intermediary element when in said engagement position.

Abstract: A vehicle seat assembly includes a seat bottom and a seat back connected to the seat bottom. A reclining mechanism is configured to adjustably position the seat back. A head restraint assembly includes a head restraint and one or more supports receiving the head restraint extending through one or more slots in an upper frame member of the seat back frame. A head restraint adjustment mechanism cooperates with the seat back to position the head restraint adjacent an occupant's head. The head restraint adjustment mechanism includes a guide rotatably mounted to the seat back frame receiving the one or more head restraint supports, a cam rotatably mounted to the seat back frame and a linkage having a first end connected to the guide and a second end adjustably connected to the cam.

Abstract: A tilt-adjustable head restraint assembly includes a hollowed head restraint body pivotally connected to a U-shaped mounting post. A ratcheting mechanism is disposed within the head restraint body and includes a ratchet interacting with a rack of ratchet teeth. The ratchet has an inertia gear engaged therewith to slow the forward movement of the pivoting head restraint when the ratchet is engaged to allow forward movement of the head restraint, and further has a plunger mechanism which allows for the pivoting of the head restraint in a hands free manner by the application of a static force or pressure.

Abstract: A vehicle seat for use with a vehicle includes a seatback frame and a guide member attached to the seatback frame. A slide bracket is attached to the seatback frame below the guide member, and the slide bracket has a slot. The seat further includes a headrest arrangement movably associated with the seatback frame. The headrest arrangement includes a headrest and a support structure connected to the headrest and engageable with the guide member. The support structure includes a projection that extends into the slot and that is movable with respect to the slide bracket from an initial position to an actuated position. Upon sufficient impact to the vehicle, the projection moves from the initial position toward the actuated position and the support structure moves along the guide member, such that movement of the headrest is guided to provide support for the head of an occupant.
