1. A vehicle sunvisor assembly, comprising:
a vehicle body structure that includes an A-pillar, a windscreen and a roof structure with the A-pillar and the windscreen extending downward from the roof structure; and
a retractable sunvisor assembly attached to the A-pillar below the roof structure such that in a retracted orientation the retractable sunvisor assembly is positioned along-side the A-pillar and in an extended in-use orientation a portion of the retractable sunvisor assembly extends away from the A-pillar covering an upper area of the windscreen, the retractable sunvisor assembly including a base portion directly attached to the A-pillar, an extensible mechanism supported to the base portion and a spring-loaded roll-up shade mechanism having an extensible flexible sunvisor shade,
the extensible mechanism including an electric motor and a telescoping assembly, the electric motor powering the extensible mechanism thereby moving the sunvisor shade between the retracted orientation and the extended in-use orientation, the telescoping assembly has a plurality of concentrically nested tubes including at least a base tube, a first tube, a second tube, a third tube and a final tube, the base tube being attached to the A-pillar and the final tube being coupled to a movable end of the sunvisor shade, each of the first, second and third tubes having a pulley rotatably attached thereto, with at least one endless belt extending around each of the pulleys of the first, second, third and final tubes, the motor powering the endless belt such that rotation of the motor in a first direction causes the movable end of the sunvisor shade to move away from the A-pillar drawing the first, second, third and final tubes to at least partially move out of one another and rotation of the motor in a second direction draws the movable end of the sunvisor shade toward the A-pillar drawing the first, second, third and final tubes to return to a nested orientation concentrically within one another.
