Abstract:
1. 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; a locking mechanism disposed at least partially between said first track member and said second track member and including at least two locking pawls and at least two actuation arms attached to said at least two locking pawls to move said at least two locking pawls in a linear path between a locked state, where one of said at least two locking pawls is engaged with said series of locking features to restrict relative movement between said first track member and said second track member, and an unlocked state, where said at least two locking pawls are disengaged from said series of 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, said at least two locking elements of said one of said at least two locking pawls are received within respective ones of said series of locking features in said locked state such that each of said at least two locking elements simultaneously restricts relative movement between said first track member and said second track member in two directions when said one of said at least two locking pawls is in said locked state; a mounting bracket including pockets in which said at least two actuation arms are movably disposed, said mounting bracket including a top wall abutting said second track member, said mounting bracket including stop features interacting with said at least two actuation arms to limit movement of said at least two actuation arms along said linear path; and an actuator partially disposed within said mounting bracket and movable therein to selectively apply a force on said at least two locking pawls to maintain said at least two locking pawls in said unlocked state, wherein at least one of said at least two locking pawls is in said unlocked state at any given time.
