Recliner mechanism

A recliner mechanism for adjusting the position of a seat back frame assembly with respect to a seat base frame assembly, the recliner mechanism comprising:

• a round sector member having a plurality of teeth located on an edge of the round sector member;
• first pawl member having a notched edge portion located between a proximal end and a distal end;
• first cam pin member having first and second axes of rotation, wherein the first cam pin member is rotatably connected to the seat back frame assembly for rotation about the first axis of rotation and is rotatably connected to the distal end of the first pawl member;
• a second pawl member having a notched edge portion located between a proximal end and a distal end, wherein the proximal end of the first pawl member is rotatably connected to the proximal end of the second pawl member and the second pawl member is connected to the other of the seat back frame assembly and the seat base frame assembly from the round sector member;
• a second cam pin member having first and second axes of rotation, wherein the second cam pin member is rotatably connected to the seat back frame assembly for rotation about the first axis of rotation and is rotatably connected to the distal end of the second pawl member;
• wherein the first and second cam pin members are connected such that rotation of the first and second cam pin members causes the first and second pawl members to rotate in opposite directions about their proximal ends;
• wherein the first and second pawl members are aligned with the round sector member such that the notched edge portions of the first and second pawl members engage the plurality of teeth of the round sector member.

A recliner mechanism, comprising:

• a round sector member having an edge with a plurality of teeth and connected to at least one of a seat back frame and a seat base frame;
• a first pawl member having a notched edge portion located between a first end and a second end and being connected to the other of the seat back frame and the seat base frame;
• a second pawl member having a notched edge portion located between a first end and a second end, wherein the first end of the first pawl member is rotatably connected to the first end of the second pawl member and the second pawl member is connected to the other of the seat back frame and the seat base frame;
• the first and second pawl members are aligned with the round sector member such that the notched edge portions of the first and second pawl members;
• and
• a first cam pin member connected to the second end of the first pawl member and a second cam pin member connected to the second end of the second pawl member, so that rotation of the first and second cam pin members causes the first and second pawl members to rotate in opposite directions about their proximal ends to releasably engage the first and second pawl members with the plurality of teeth of the round sector member.
