Seat Reclining Apparatus For Vehicle
Patent No. EP2261074 (titled "Seat Reclining Apparatus For Vehicle") was filed by Aisin Seiki Kabushiki Kaisha on Mar 30, 2010. The application was issued on Jan 4, 2017.
Patent Summary
A vehicle seat reclining apparatus comprises a first arm with an internal gear and a first circumferential portion, and a second arm with an external gear (having fewer teeth) and a second circumferential portion. First and second wedge members, biased by a spring, are accommodated between these circumferential portions. Each wedge member features a pressure portion and a circumferential contact surface, creating a wedged state when the circumferential portions contact eccentrically. A drive shaft, operated by a drive unit, releases this wedged state to rotate the second arm relative to the first. To prevent noise from static friction during subsequent adjustments, each wedge member's circumferential contact surface includes a lubricant-retaining groove extending along the rotation axis of the arms.
