A window regulator guide rail is provided, including an elongated body having a snap anchor; and a ring rotatably coupled to the rail via engagement with the snap anchor, the ring for guiding a cable.

A window regulator includes a guide and an elongated carrier attached to the guide. A drive cable is driven by an actuator to move the carrier relative to the guide. A support cable includes a first end that is attached to a forward edge of a window opening of a door structure. The support cable includes a second end that is attached to a lower end of the guide. A first direction control device is attached to and rotatably supported by the carrier, proximate to a forward edge of the window opening. A second direction control device is attached to and rotatably supported by the carrier, and is disposed rearward of the first direction control device, between the first direction control device and the guide. The support cable is engaged with and guided by the first direction control device and the second direction control device.

A window regulator, including: a first guide rail; a first cursor slidably mounted to the first guide rail; a second guide rail spaced from the first guide rail; a second cursor slidably mounted to the second guide rail; a housing that is not mounted to a lower end of the first guide rail or the second guide rail; a motor mounted to the housing and operably coupled to the first cursor and the second cursor such that operation of the motor will cause the first cursor to slide along the first guide rail and second cursor to slide along the second guide rail; a cable drum rotationally mounted to the housing, the cable drum being operably coupled to the motor and a first cable secured to the cable drum at one end and the first cursor at another end; a second cable secured to the cable drum at one end and the second cursor at another end; a third cable secured to the first cursor at one end and the second cursor at another end; a first cable sheath surrounding the first cable that extends from a first feature of the first guide rail to the housing; a cable tensioner associated with the first cable sheath; a second cable sheath surrounding the second cable that extends from the housing to a second feature of the second guide rail; and a third cable sheath surrounding the third cable that extends from the a second feature of the first guide rail to a first feature of the second guide rail, wherein the window regulator is configured for raising and lowering a window of a frameless door assembly of a vehicle.

A single-rail window regulator for moving a side window of a vehicle in an upward direction and in a downward direction includes a guide rail defining and a carrier plate having a central guide structure for movably engaging the guide rail, a first lateral extension extending to a first lateral side of the guide rail, and a second lateral extension extending to a second lateral side of the guide rail body opposite the first lateral side. The carrier plate has a first cable attachment pocket on the first lateral extension and a second cable attachment pocket on the second lateral extension. Accordingly, the two attachment pockets are arranged on opposite lateral sides. As one cable end pulls the carrier plate upward and the other cable end pulls the carrier plate downward, the arrangement causes torques in the same rotational direction, even when reversing the direction of movement.

A cable tensioner for a window assembly of a motor vehicle closure panel has a baseplate supporting a tension lever for pivotal movement between a first position, whereat tension lever imparts a first tension in a cable, and a second position, whereat tension lever imparts a second tension in the cable, the second tension being substantially the same as the first tension. A ratcheting arrangement prevents tension lever from returning toward the first tension position. Tension lever is biased toward the first position by a biasing member. Biasing member has a first end operably fixed to baseplate and a second end arranged in biased engagement with tension lever, wherein biasing member is under preload to maintain tension lever in constant engagement with cable.

This disclosure is directed to a cable tensioner having a regulating stick, a tube assembly and a spring. The regulating stick has an abutting portion and a ratchet strip. The ratchet strip has multiple ratcheting notches having a stop surface and a slope opposite to each other. The tube assembly sleeving the regulating stick has an outer cylinder and an inner cylinder. The outer cylinder has A second abutting portion and a pawl. The pawl has an elastic arm and a hook portion. The hook portion has a stopping side abutting against the stop surface. The hook portion engages one of the ratcheting notches. The spring is preloaded and clamped between the first and second abutting portions. One end of the inner cylinder abuts a side of the hook portion opposite to the stopping side.
