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.
