Abstract: A recliner heart includes first, second and third locking plates and a pawl. The first locking plate defines a recess. The second locking plate includes a first inner diametrical surface having first teeth formed thereon. The third locking plate is disposed between the first and second locking plates and includes a second inner diametrical surface and an outer diametrical surface. The second inner diametrical surface has a notch formed therein. The outer diametrical surface has second teeth formed thereon. Some of the second teeth are meshingly engaged with some of the first teeth. The pawl is slidably disposed in the recess between a secure position in which the pawl is engaged with the notch of the third locking plate and a release position in which the pawl is disengaged from the notch of the third locking plate.

Abstract: A vehicle seat-track assembly is provided and may include a first track member having a series of locking features and a second track member slidably supported by the first track member. The seat-track assembly may also include a locking mechanism having locking pawls movable between a locked state engaged with the locking features to restrict relative movement between the first and second track members and an unlocked state disengaged from the locking features to permit relative movement between the first and second track members. The locking pawls may each include locking elements that are received within respective ones of the series of locking features in the locked state such that the locking elements restrict relative movement between the first track member and the second track member in two directions when the locking pawls are in the locked state.
