Patent number: 11897372Abstract: A recliner heart includes a first locking plate, a second locking plate, a hub, a pair of wedges, a first biasing member, and a second biasing member. The first locking plate includes first teeth. The second locking plate is rotatable relative to the first locking plate and includes second teeth. The first biasing member is configured to apply a first biasing force to the wedges. The second biasing member is configured to apply a second biasing force to the wedges. The hub is rotatable between a first position in which the first and second biasing forces are applied to the wedges to restrict rotation of the second locking plate relative to the first locking plate, and a second position in which the first biasing force applied to one wedge of the wedges is reduced to allow rotation of the second locking plate relative to the first locking plate.Type: GrantFiled: April 14, 2022Date of Patent: February 13, 2024Assignee: Fisher & Company, IncorporatedInventors: Ralph L.

Publication number: 20220355709Abstract: A recliner assembly for a vehicle seat may include a pair of recliner hearts and a cross rod. Each of the recliner hearts includes a first plate and a second plate that is selectively rotatable relative to the first plate to recline a seatback relative to a seat bottom of the vehicle seat. The cross rod extends between the recliner hearts and is received in hubs of the recliner hearts. The cross rod transmits torque between the hubs. The cross rod includes ridges that are angularly spaced apart from each other. Each of the ridges includes a first sidewall, a second sidewall, and an end wall extending between the first and second sidewalls. The first and second sidewalls are defined by first and second axes that extend radially outward. The first and second axes are angled such that they do not converge with each other as they extend radially outward.Type: ApplicationFiled: April 14, 2022Publication date: November 10, 2022Applicant: Fisher & Company, IncorporatedInventors: Ralph L.
