Motor-driven screen roller assembly for automobiles

A motor-driven screen roller assembly for subdividing a passenger space inside a motor vehicle, comprising:

• a pair of screens for dividing the passenger space inside the motor vehicle, said screens having lower free ends coupled respectively to a pair of slats;
• a pair of rollers suspended inside the passenger space of the motor vehicle, each of said rollers having coupled thereto an upper end of a respective one of said pair of screens, wherein when each said roller is rotated in a forward direction said lower free end of said respectively coupled screen is lowered and when each said roller is rotated in a backward direction said free end of said respectively coupled screen is raised;
• a pair of power drives coupled respectively to said pair of rollers, each of said power drives including at least one reversible DC motor coupled to a respective one of said pair of rollers for rotating said roller in said forward direction to lower said screen, for rotating said roller in said backward direction for raising said screen, and for stopping said rotations of said roller;
• and,
• a control circuit for providing selective control of each said power drive and said respective roller coupled thereto, said control circuit including a FORWARD/STOP/BACKWARD switch and a selector switch coupled in series for controlling a selected one of said power drives, said FORWARD/STOP/BACKWARD switch being connected between a battery power supply circuit of the motor vehicle and said selector switch, said selector switch being connected between said FORWARD/STOP/BACKWARD switch and both of said pair of power drives to selectively connect one of said power drives to said FORWARD/STOP/BACKWARD switch for control thereby, said FORWARD/STOP/BACKWARD switch being adapted to provide a selection between forward rotation, backward rotation and stopping of said selected one of said pair of power drives to correspondingly lower said screen, raise said screen and halt movement of said screen.
