A seat-track assembly comprising: a first track member having a series of locking features; a second track member slidably supported by said first track member, said second track member having a top wall and sidewalls; and a locking mechanism disposed at least partially between said first track member and said second track member and including at least two locking pawls movable between a locked state engaged with said locking features to restrict relative movement between said first track member and said second track member and an unlocked state disengaged from said locking features to permit relative movement between said first track member and said second track member, said at least two locking pawls each including at least two locking elements that are received within respective ones of said series of locking features in said locked state such that each of said locking elements simultaneously restrict relative movement between said first track member and said second track member in two directions when said locking pawls are in said locked state; wherein said locking mechanism further comprises a series of biasing members and a mounting bracket; wherein said locking pawls are received within said second track member generally between said top wall and said sidewalls, and comprise a main body, and an actuation arm integrally formed with or separately formed from said main body, wherein said actuation arm is fixed for movement with said main body; wherein said biasing members surround a portion of said actuation arms and are arranged to exert a force on said actuation arms; and wherein said biasing members are retained between a bottom wall of said mounting bracket and said top wall of said second track member characterized by an actuator supported by said mounting bracket to move said at least two pawls from said locked state to said unlocked state; wherein said actuator is operable to selectively apply a force on said at least two pawls to maintain said at least two pawls in said unlocked state. a first track member having a series of locking features; a second track member slidably supported by said first track member, said second track member having a top wall and sidewalls; and a locking mechanism disposed at least partially between said first track member and said second track member and including at least two locking pawls movable between a locked state engaged with said locking features to restrict relative movement between said first track member and said second track member and an unlocked state disengaged from said locking features to permit relative movement between said first track member and said second track member, said at least two locking pawls each including at least two locking elements that are received within respective ones of said series of locking features in said locked state such that each of said locking elements simultaneously restrict relative movement between said first track member and said second track member in two directions when said locking pawls are in said locked state; wherein said locking mechanism further comprises a series of biasing members and a mounting bracket; wherein said locking pawls are received within said second track member generally between said top wall and said sidewalls, and comprise a main body, and an actuation arm integrally formed with or separately formed from said main body, wherein said actuation arm is fixed for movement with said main body; wherein said biasing members surround a portion of said actuation arms and are arranged to exert a force on said actuation arms; and wherein said biasing members are retained between a bottom wall of said mounting bracket and said top wall of said second track member characterized by an actuator supported by said mounting bracket to move said at least two pawls from said locked state to said unlocked state; wherein said actuator is operable to selectively apply a force on said at least two pawls to maintain said at least two pawls in said unlocked state.
