Motorized window shades for RVs
A motorized shade assembly is provided having a discontinuous web extending between two rollers, one of which is motorized and the other is tensioned or biased toward rotation away from the other roller. The roller motor can be mounted inside of one of the rollers, and the tensioning device, such as a torsion spring, can be mounted inside of the other roller. The web includes a shade portion and a strap portion, with a rigid draw bar at the junction of those portions. Rotation of the rollers causes the strap portion to wrap over one of the rollers as the shade portion unwraps from the other roller. The shade assembly can be positioned between an inclined or curved vehicle window and an interior shroud for the window, such as found with a cab-over window of a Class B motorhome. The draw bar and fasteners connecting the strap to the draw bar facilitate movement of the shade when in contact with the shroud. Friction reducing tape or surface treatment on the periphery of the window opening in the shroud can also facilitate movement of the shade when in contact with the shroud. Motor actuation can be hardwired to a desired location within the vehicle, or wirelessly controlled by the user, as with an RF device.
