Recliner mechanism for seat assembly and method of manufacturing
A method for manufacturing a recliner mechanism may include movably attaching a first plate of a recliner heart to a second plate of the recliner heart, positioning a gap ring onto the first plate of the recliner heart, positioning an encapsulation ring around the first and second plates such that the gap ring is disposed axially between the first plate and the encapsulation ring, and removing at least a portion of the gap ring from between the first plate and the encapsulation ring to form a clearance gap between the first plate and the encapsulation ring.
1. A method for manufacturing a recliner mechanism comprising:
movably attaching a first plate of a recliner heart to a second plate of the recliner heart;
positioning a gap ring onto the first plate of the recliner heart;
positioning an encapsulation ring around the first and second plates such that the gap ring is disposed axially between the first plate and the encapsulation ring; and
rotating the first plate while the second plate and encapsulating ring are held stationary to generate friction, such that the generated friction burns or melts off at least a portion of the gap ring to form a clearance gap between the first plate and the encapsulation ring.
2. The method of claim 1 , wherein the first plate includes a plate surface and a rim extending around a periphery of the plate surface, and wherein the gap ring is positioned onto the rim of the first plate.
3. The method of claim 2 , wherein the encapsulation ring includes a body and a flange extending radially inwardly from an axial end of the body, and wherein the gap ring is positioned between the flange and the rim of the first plate.
4. The method of claim 1 , wherein positioning the encapsulation ring around the first and second plates includes press-fitting the encapsulation ring onto the second plate.
5. The method of claim 1 , wherein the gap ring is formed from a polymeric material and/or a paper material.
6. The method of claim 1 , wherein the first plate is disposed axially between the second plate and a flange of the encapsulation ring, and wherein the clearance gap is formed axially between the first plate and the flange.
7. A method for manufacturing a recliner mechanism comprising:
movably attaching a first plate of a recliner heart to a second plate of the recliner heart;
positioning a gap ring onto the first plate of the recliner heart;
positioning an encapsulation ring around the first and second plates such that the gap ring is disposed axially between the first plate and the encapsulation ring, a first surface of the gap ring contacts the first plate and a second surface of the gap ring opposite the first surface contacts the encapsulation ring;
press fitting the encapsulation ring onto the second plate;
after press fitting the encapsulation ring onto the second plate, rotating the first plate while the second plate and encapsulating ring are held stationary to generate friction, such that the generated friction burns or melts off at least a portion of the gap ring to form a clearance gap between the first plate and the encapsulation ring; and
welding the encapsulation ring to the second plate of the recliner heart.
8. The method of claim 7 , wherein the first plate includes a plate surface and a rim extending around a periphery of the plate surface, and wherein the gap ring is positioned onto the rim of the first plate.
9. The method of claim 8 , wherein the encapsulation ring includes a body and a flange extending radially inwardly from an axial end of the body, and wherein the gap ring is positioned between the flange and the rim of the first plate.
10. The method of claim 7 , wherein the gap ring is formed from a polymeric material and/or a paper material.
11. The method of claim 7 , wherein the first plate is disposed axially between the second plate and a flange of the encapsulation ring, and wherein the clearance gap is formed axially between the first plate and the flange.
