  • Patent number: 6983786
    Abstract: A height-adjustable car curtain, mainly characterized by having a case, roughly shaped like a tube with two ends to which connecting elements are attached, connecting to guiding rails at adjustable angles. The guiding rails allow to be cut to suitable lengths. Therefore, car windows of various sizes are readily adapted to. Furthermore, a winding device is provided for winding and unwinding a cord, causing a curtain to be unfolded and folded. The winding device has a control system with a lever arm and a contact switch for switching off a motor upon the cord becoming slack, thus preventing the cord from becoming tangled. Lastly, a directly or remotely operated control circuit is provided, controlling operation of a motor of the winding device, in particular causing the motor to stop and reverse direction if the unfolding or folding curtain encounters an obstacle, preventing damaging of the motor.
