Definitions

• the invention relates to a window protection system, in particular for road vehicles against bad weather, snow, ice, ice, frost, rain, for vehicles which remain outside in winter and the windows of which must be cleaned in order to be able to use it. Said system also protects against the sun which normally causes a significant rise in internal temperature by making access very difficult.
• the object of the system according to the invention is to overcome these various drawbacks and to increase the service provided to users.
• It is characterized in that it comprises curtains made of natural or synthetic material mounted on rollers provided with a winding means and disposed inside a housing and in that said system is implemented at the interior of the rear spoiler for reducing aerodynamic drag, said curtains being operated by automatic means from the rear spoiler to the front of the vehicle by covering successively the rear window, the roof, the front window and, at the end of the course, the side windows; and in that it comprises:
• a traction tube cooperating with fasteners each secured with a portion of axis sliding in said traction tube and guide rods integral with the chassis of the vehicle and arranged on either side of the central curtain, said tube traction comprising a means of elastic attachment of the inner end of each of the two side half-curtains allowing them to be deployed on the side windows of the vehicle,
• the device does not modify the exterior appearance of the vehicle and therefore does not offer relative wind resistance because it is hidden in the aerodynamic drag reduction spoiler,
• - Fig.1 shows the entire device according to the invention in place on a car folded in the rear spoiler
• - Fig.3 and 4 show the arrangement of the side fabrics relative to the roof protection fabric; - Fig.5 shows, in section, the location of the device inside the aerodynamic drag reduction spoiler,
• - Fig.6 shows, in top view, the curtain operating device
• Fig.7 shows, in section, a guide strip for the curtain traction wires
• Figs. 13 and 14 show an example of a command to install the side curtains.
• Fig.1 shows the system in place in the spoiler 1 attached to the rear of a car, we also showed the rods 2,3 for guiding the traction cords as well as the housings 4,5 of the return pulley traction cords of the protective curtains and bars 6 forming an air mattress between the curtains and the roof of the vehicle.
• Figs. 2 and 3 show the protection system deployed. It comprises an upper fabric 7 covering the rear window 8, the top of the the car and the front window and the two half-curtains 9,10 apart to cover the side windows. The means of implementation will be described later.
• Figs. 5 and 6 we have shown the spoiler 1 in section with the winding device comprising a roller 15 deploying on the top of the vehicle roof and a roller 16 located behind the first roller and comprising two half-curtains 9.10 deploying laterally.
• the curtains are wound on axes 21, 23 rotating in bearings 19, 20.
• the rear tail end 21 is coupled to a gear motor
• the shaft 23 is rotated from the axis 21 by a toothed belt transmission 24 cooperating with toothed pulleys 25, 26 secured to the axes 21, 23.
• the shaft 23 is provided, at each of its ends, with a winch drum 27, 28 on which are respectively wound pull cords 29, 30 of the curtains, they each pass over a grooved pulley 31, 32 located at the front of the rods 2,3 for guiding said cords inside a box 4,5 fig. 1 and each return to an attachment tab 33,34 secured to the traction tube 35 and from the front curtains by means of lugs 36,37 crimped on the exté ⁇ laughing ends of the curtains 7 and 9,10 the details of which are shown in fig.7,8, 9,10.
• a rod 2,3 for guiding the pull cords 29.30 there is shown a return strand 38 of the cord 29.30, and a possible cord 39 ensuring the unlocking of the mechanism allowing the sliding lateral of the curtain 9,10 in the case of manual operation only.
• This cord passed through a ring of the traction tube, is not used in the event of automatic operation of the curtains.
• Said rod 2,3 is open on one side at 40 to let pass a tab 33,34 for attaching the traction cord by tightening elastically on the latter to ensure the seal between tab and rod; said rod can be made of extruded plastic.
• cords can be hung, at the front of the car, on one or two rings making it possible to manually pull on the branch 49 of the lever by the cord 39 to retract it and release the stop which has the effect, in cooperation with ribbons of elastic material placed at the front and rear of the half-curtains, to bring them up in the rewinding position.
• This maneuver can be made automatic by replacing the lever and its manual control with 2 electromagnets acting directly on the stop 45 of each of the half-curtains, said electromagnets normally being in the stop position.
• openings 53 are provided for the evacuation of the water or of the melting of the snow scraped by the bevel.
• Fig.11 and 12 show, in sectional views of the tube 35, an embodiment of such a plastic tube molded in two parts 79.80 whose section is elliptical to allow the passage of the spring 67 along grooved pulleys 63,64 rotating on a metal axis 76 fitted into bosses 77,78 of the 1/2 parts 78,79 of the tube 35.
• the pulleys 65,66 are arranged in the vertical central axis of the said tube mounted like the pulleys 63,64.
• the pulleys, the spring 67 and the cor ⁇ donations 61.62 are put in place before mounting the 1/2 parts 79.80.
