Abstract:
A window regulator for use with a vehicle window assembly having first and second panes slidable toward one another to a closed position and away from one another to an open position, the regulator comprising:an elongated guide rail having first and second ends;first and second pane carriers slidingly movable along the guide rail and engageable with the first and second panes respectively;a drive drum;means for rotating the drive drum;a first flexible, inextensible member having a first end attached to the first pane carrier, extending from the first pane carrier toward and passing around a first guide element disposed adjacent the first end of the guide rail, and having a second end engaged with the drive drum;a second flexible, inextensible member having a first end attached to the second pane carrier and a second end engaged with the drive drum; anda third flexible, inextensible member having a first end attached to the first pane carrier, extending from the first pane carrier toward and passing around a second guide element disposed adjacent the second end of the guide rail, and having a second end attached to the second pane carrier;whereby rotation of the drive drum in a first direction pulls on the first inextensible member to move the first pane carrier toward the first end of the guide rail and said movement of the first pane carrier pulls on the third inextensible member to move the second pane carrier toward the second end of the guide rail, and rotation of the drive drum in a second direction opposite the first direction pulls on the first end of the second inextensible member to move the second pane carrier toward the first end of the guide rail which causes the second pane carrier to pull on the third inextensible member to move the first pane carrier toward the second end of the guide rail.
