A 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.
