Furniture member powered headrest rotation and release system
DCFirst Claim
1. A furniture member powered headrest operating system, comprising:
- a headrest frame assembly rotatably connected to a furniture member seatback frame; and
an actuation mechanism connected to the seatback frame, the actuation mechanism having a power actuated member connected to the headrest frame assembly operating to rotate the headrest frame assembly between a fully retracted to a fully forward rotated position;
a biasing member connected to the furniture member seatback frame and the headrest frame assembly defining a biasing member axis of connection displaced with respect to a frame assembly axis of rotation to induce rotation of the headrest frame assembly from a biasing force of the biasing member, wherein the biasing force is created during rotation of the headrest frame assembly away from the fully retracted position and operates to bias the headrest frame assembly from the fully forward rotated position to the fully retracted position without an operating force of the actuation mechanism; and
the seatback frame further including first and second seatback side members, the headrest frame including first and second rotational pins each rotatable connected to one of the first or second seatback side members, the first and second rotational pins defining a frame assembly axis of rotation.

Abstract
A powered headrest operating system includes a headrest connected to a seatback frame using rotational pins. An actuation mechanism rotatably connected to the seatback frame has a power actuated member connected to the headrest operating between retracted and extended positions to rotate the headrest from a fully retracted to a forward rotated position about an axis of rotation of the rotational pins. A release system rotatably connecting the headrest to the actuation mechanism retains the headrest at any forward rotated position while the actuation mechanism returns the power actuated member from the extended to the retracted positions if the headrest encounters an object blocking return to the retracted position. A biasing member connected to the seatback frame and the headrest creating a biasing force during headrest rotation away from the retracted position operates without actuation mechanism operating force to bias the headrest frame assembly toward the retracted position.

4. A furniture member powered headrest operating system, comprising:
-
a headrest frame assembly rotatably connected to a furniture member seatback frame; and an actuation mechanism connected to the seatback frame, the actuation mechanism having a power actuated member connected to the headrest frame assembly operating to rotate the headrest frame assembly between a fully retracted to a fully forward rotated position; a biasing member connected to the furniture member seatback frame and the headrest frame assembly, wherein a biasing force is created during rotation of the headrest frame assembly away from the fully retracted position which operates to bias the headrest frame assembly from the fully forward rotated position to the fully retracted position without an operating force of the actuation mechanism; and a release system rotatably connecting the headrest frame assembly to the actuation mechanism operating to permit rotation of the headrest frame assembly from the fully forward rotated position back to the fully retracted position by only a biasing force of the biasing member, wherein the release system includes; a pin connecting bracket connected to the headrest frame assembly; a semi-circular slot created in the pin connecting bracket; and a pin connected to the power actuated member of the actuation mechanism and slidably received in the semi-circular slot, wherein the pin contacts a first slot end wall of the semi-circular slot during rotation of the headrest from the fully retracted to the fully forward rotated positions, the pin slidably displaced toward a second slot end wall of the semi-circular slot during rotation from the fully forward rotated position to the fully retracted position if the headrest frame assembly encounters an object.
