Abstract:
An automotive vehicle has a power operated lift-gate that is opened and closed by two drive units. The typical drive unit has a guide channel, an attachment assembly that is disposed in the guide channel, a flexible drive member that is attached to the attachment assembly and formed in a loop for moving the attachment assembly in the guide channel. The flexible drive member is trained solely around two pulleys at the respective opposite ends of the guide channel to form the flexible drive member in a narrow loop. One of the pulleys is an idler pulley that is part of an adjustable pulley assembly and the other pulley is driven by a power unit that is attached to the guide channel. The adjustable pulley assembly adjusts the distance between the pulleys to take up slack in the flexible drive member.
