Abstract
In automobiles an arrangement for protecting the interior of the passenger compartment from becoming overheated by sun irradiation and for securing privacy of persons in the car comprises curtains adapted to be drawn over all windows of the car. The curtains are stored--when not in use--within a casing below the roof of the car and are guided in rails extending from that casing downwardly. The curtains are drawn by means of a mechanism driven by an electrical motor.
Claims8
In an automobile--an installation which comprises a casing affixed to the car's roof at its inside,
- four curtains to be contained in such casing, one for the windshield, two oppositely disposed ones for the sides of the car, and one for the rear window,
- the said curtains being provided with guiding members for their lateral edges,
- which guiding means travel in rails extending within the car along members supporting the roof of the car,
- pull ropes being attached to said curtains for moving them relative to the said casing, said pull-ropes being connected to springs at one end thereof, and
- drive means connected to the other end of each said pull-rope and being provided for moving the curtains, which drive means are operable from the interior of the car,
- said drive means including electrical motor means to simultaneously drive a plurality of said curtains, and means to selectively disconnect said drive means for one or more of said plurality of curtains, so that said electric motor acts on a lesser number of said curtains.

- pull-ropes being attached to the said curtains for moving them relative to the said casing, and
- drive means being provided for moving the curtains, which drive means are operable from the interior of the car,
- wherein the drive for the movements of the curtain comprises a motor fed with electrical current from the battery of the car, two first pulleys revolving in opposite directions being driven by the motor, pull-ropes winding on the said two pulleys, said ropes leading to a second pair of pulleys fixedly attached to a first pair of crown wheels, each of which meshes with one of a first pair of pinions which latter, over a common shaft, transmit rotational movement to a second pair of pinions, which--in turn--mesh with a third pair of pinions and transmit rotational movement to a fourth pair of pinions, each of which via second and third common shafts and a fifth and sixth pair of pinions transmit movement to third and fourth pairs of crown wheels which are fixedly connected each with a reel from which pull-ropes extend to side curtains, said second and third shafts carrying seventh and eighth pinions transmitting rotational movement to a fourth shaft and a pair of ninth and tenth pinions meshing with fifth and sixth crown wheels, each of which is associated with a reel from which pull-ropes extend to the frontal curtain of the arrangement.
