A vehicular rear slider window assembly includes a fixed window panel, a movable window panel and a frame portion. An upper edge region of the movable window panel is movably received in a channel of an upper rail of the frame portion. A first biasing element is compressed between a first inner surface of the upper rail and a first side of the movable window panel and urges the movable window panel away from the first inner surface. A second biasing element is compressed between a second inner surface of the upper rail and a second side of the movable window panel and urges the movable window panel away from the second inner surface. As the movable window panel is moved between the closed and opened positions, the first and second biasing elements guide movement of the movable window panel in a direction parallel to a centerline of the channel.

A vehicular window assembly includes a window panel attached at a mounting structure. The window panel has an electrically conductive trace established at a surface of the window panel. The electrically conductive trace includes a positive end electrically connected to a positive terminal at the window panel and a negative end electrically connected to a negative terminal at the window panel. The electrically conductive trace includes a plurality of spaced apart trace segments disposed across the surface of the window panel. The plurality of spaced apart trace segments are electrically connected in series between the positive terminal and the negative terminal. With the vehicular window assembly mounted at the vehicle, a power supply of the vehicle is electrically connected to the positive terminal and the negative terminal to provide electrical power to the electrically conductive trace. Voltage supplied by the power supply is greater than 15 volts.

A method for forming a vehicular slider window assembly includes providing a fixed window panel defining an open and attaching upper and lower rails at the fixed window panel. The method includes providing a filler including a filler body and a deformable element along each opposing side wall of the filler body. The method includes forming at least one end of opposite ends of the filler body at an oblique angle relative to a longitudinal axis of the filler body. The filler is disposed in a channel of the upper rail. A movable window panel is provided at the upper and lower rails with an upper region of the movable window panel received in the filler. Each of the deformable elements includes a compressible and flexible material and provides a dampening and cushioning function at the movable window panel received in the filler in the channel of the upper rail.

In at least some implementations, a motor vehicle window assembly includes a guide rail, a movable pane movable along the guide rail between open and closed positions and a defroster. First and second guide rail conductors are carried by the guide rail and adapted to be connected to a power source. First and second movable conductors are each electrically communicated with a respective one of the first and second guide rail conductors, each electrically coupled to the defroster and each movable with the movable pane relative to guide rail when the movable pane is moved between the open and closed positions. To provide power to the defroster, the movable conductors are in contact with the guide rail conductors when the movable pane is in the closed position and during movement of the movable pane between the open and closed positions.

A rear window assembly for a vehicle includes a fixed window panel. The rear window assembly may be a rear slider window assembly and may include a frame portion having an upper rail and a lower rail, with the fixed window panel fixed relative to the frame portion and defining an opening, and with a movable window panel movable along the upper rail and the lower rail so as to be movable between a closed position and an opened position. A lighting device is disposed at an inner surface of the fixed window panel. The lighting device is operable to emit light that passes through the fixed window panel so as to be viewable by a person viewing the slider window assembly from exterior and rearward of the vehicle.

A sliding window assembly for a vehicle includes a fixed panel and a sliding panel moveable relative to the fixed panel. A track is connected to the fixed panel. The track includes an elongated member having a base portion and first and second legs extending from the base portion to define a channel. The first leg is connected to the fixed panel and the second leg is spaced from the first leg. The sliding panel is disposed within the channel and is slidable along the track relative to the fixed panel. The first leg defines a drain hole in communication with the channel and an exterior of the vehicle for draining water from the channel to the exterior of the vehicle.

A method for manufacturing a vehicular rear slider window assembly includes attaching an upper rail and a lower rail at an inner side of a fixed window panel. The lower rail includes a first attaching surface that attaches at the fixed window panel and a second attaching surface opposite the first attaching surface. The method includes disposing a movable window panel in a channel of the lower rail and a channel of the upper rail and attaching a retaining element along the lower rail and at the second attaching surface of the lower rail. The retaining element includes an attaching portion that attaches at the second attaching surface and a retaining portion that extends at least partially across the channel of the lower rail to limit vertical movement of the movable window panel relative to the upper and lower rails.

A vehicular rear slider window assembly includes a fixed window panel, a movable window panel, and a frame portion fixed relative to the fixed window panel. The fixed window panel has an opening, and the movable window panel is movable along upper and lower rails of the frame portion between a closed position and an opened position. Electrically conductive traces are established at a surface of the fixed window panel, and electrically conductive traces are established at a surface of the movable window panel. Electrical power to the electrically conductive traces of the movable window panel is provided wirelessly throughout all positions of the movable window panel between and including the opened position and the closed position.

A vehicular rear slider window assembly includes a fixed window panel, a movable window panel, a frame portion fixed relative to the fixed window panel, and an opening through the fixed window panel. The movable window panel is movable along upper and lower rails of the frame portion between closed and opened positions. A slider bearing system includes a guide element disposed at least partially along the lower rail and a carriage disposed at a lower perimeter region of the movable window panel. The guide element includes a bearing element that is slidably and non-rotatably received at a bearing receiving portion of the carriage. The carriage moves in a direction parallel to a longitudinal axis of the bearing element when the movable window panel moves between the closed position and the opened position.

A motor vehicle window assembly. One implementation includes a wiper in electrical communication between a defrost grid of a movable window assembly and an elongate conductor of a guide rail assembly having a straight guide portion and an oblique guide portion, and in contact with the elongate conductor when the movable window assembly is in an open position. Another implementation includes an actuator cable including a core having a terminus coupled to a cable connector portion of a movable window assembly, wherein when the actuator cable is actuated, the movable window assembly moves in a direction extending away from an open position along a plane, toward a closed position out of the plane, and into the closed position in another plane such that the terminus of the core is carried out of the plane by the movable window assembly.
