The present invention relates generally to a motorized sun visor for a motor vehicle.
More particularly, this invention pertains to a motorized sun visor that is disposed between the roof of the motor vehicle and the head liner wherein the sun visor is hidden from normal view until deployed by at least one actuator. The sun visor may include a frame and a screen that is operably driven by the at least one actuator.
Sun visors are common to many motor vehicles and are often placed adjacent to the windshield so that they can be pivoted downward to block the upper portion of a windshield while still allowing the direct viewpoint of the driver to be clear. The operation of a common sun visor can be distracting and require the driver to manually move the sun visor into an adequate position. Movement of the sun visor can require at least one hand to be taken off of the steering wheel and may require the driver to take their eyes off the road to locate the sun visor above them. These issues can leave the driver distracted and not paying attention to the road or other motor vehicles around them.
Additionally, the sun visor can be aesthetically unpleasing and take up desired head room of occupants. Large, bulky sun visors create an additional element that must be attached to the head liner and are exposed over what often is an otherwise smooth headliner that is aesthetically clean and pleasant. Sun visors can also become loose over time and droop into the sightline of the driver causing poor vision conditions.
What is needed, then, is a sun visor that takes up little headroom in the cabin, is aesthetically pleasing, and minimizes the distraction of the driver while deploying and/or positioning the sun visor when needed.
In some embodiments, a sunshade apparatus for a motor vehicle may include a frame. The frame may include a first rigid member, a second rigid member, and an intermediate member that may be rotatably connected to the first rigid member and second rigid member.
In some embodiments, the apparatus may include a screen disposed between the first rigid member and second rigid member.
In some embodiments, the apparatus may include an actuator wherein the intermediate member may be fixedly connected to the actuator and the actuator may operably drive the frame and screen. The frame and screen may be selectively and incrementally positionable between a fully deployed position and a fully retracted position.
In some embodiments, the actuator may be connected to the intermediate member wherein the intermediate member is rotatable about the actuator connection.
In some embodiments, the intermediate member may include a first end and a second end. The first rigid member may be located closer to the first end than the second end. The second rigid member be located closer to the second end than the first end. The intermediate member may further include an axis along its length with a rotating pin and slot for rotating the first and second rigid members about the axis.
In some embodiments, the apparatus may include a motor operably connected to the actuator and in electrical communication with an on-board electrical power source of the motor vehicle. In some embodiments, the motor may be operably connected to the actuator and in electrical communication with an electric power source separate from an electrical power source of the motor vehicle.
In some embodiments, the actuator may include a plurality of actuators, each actuator of the plurality of actuators may be fixedly connected to the intermediate member.
In some embodiments, the screen may be opaque. In some embodiments, the screen may be semi-transparent.
In some embodiments, the screen may include an interior-facing surface and exterior-facing surface wherein the interior-facing surface may include a reflective panel. In some embodiments, the screen may include the exterior-facing surface having a solar panel.
In some embodiments, the apparatus may include a mount connected to the actuator and configured to be mounted to the roof of the motor vehicle. The apparatus may be disposed between the roof of the motor vehicle and a headliner. The screen may include a leading edge wherein in the fully retracted position, the leading edge is seated flush with the headliner and the remaining screen is non-visible between the roof and headliner.
