DESCRIPTION

Sunshade for vehicles.

The invention relates to a parasol of the kind indicated in detail in the preamble of claim 1, such as that disclosed, for example, by document EP 0 231 440 B1 or generic document EP 0 499 020 B1.

The aforementioned parasols have given excellent results in practice, above all because they offer significantly improved protection against light compared to conventional parasols provided with parasol bodies that are not displaceable along the axis. On the other hand, the sun visors shown in the cited documents no longer satisfy the current consumer requirements, which require complementary functions of the sun visors.

To satisfy these requirements, it is proposed according to the invention, starting from a parasol of the kind mentioned at the beginning, a parasol characterized in that its body is equipped with at least one connection device for connecting and disconnecting an electric lighting device, a remote control unit for controlling an automatic device for opening and closing garage doors or the like and a line comprising several conductive wires, being carried out through the line, which can be connected to the general electrical system of the vehicle, a permanent power supply independent of the respective position of the body of the sun visor for the at least one connection device electrically connected with the line and for the unit of remote control connected electrically also with the line.

The sun visor according to the invention can be folded down in the conventional way from a rest position, in which it is applied to the internal roof of a vehicle, to a position of use in front of a vehicle windshield and can be further tilted towards a side window of the vehicle . In both positions the body of the sun visor is movable along its axis, with the particularity that it is equipped with at least one connection device to connect and disconnect an electric lighting device, a remote control unit and an electric line. that ensures a current supply, specifically in the rest position, in the position of use and in any position of movement of the body of the parasol on the axis. The lighting device cooperating with the connecting device can be housed in the body of the sun visor, for example as part of a standard mirror unit, but can also be arranged externally to it, for example on the internal roof of a vehicle, to it can also be used in the dark, for example, a mirror arranged on the body of the parasol.

The remote control unit arranged according to the invention in the body of the sunshade, which belongs to the state of the art in itself, can be used to control several automatic devices for opening and closing several garage doors, parking barriers, gates. of private dwellings and the like and may be equipped with a corresponding number of switches. The number of conductive wires in the line is adjusted to the number of switches to be provided.

The requirement for a permanent supply of current to the remote control unit in a movable sun visor is advantageously satisfied by making the line have an excess length corresponding to the maximum travel travel of the sun visor body. Therefore, there is always a line reserve when the sun visor body is transferred from its normal position to an offset position.

A particularly advantageous development of the invention provides that the extra length of the line is housed within the body of the sun visor. In this way, aesthetic requirements can also be satisfied. Based on this, it is provided in another advantageous embodiment of the invention that the line connected to the at least one connection device and to the remote control unit, on the one hand, runs through the shaft, which is of hollow construction, and , on the other hand, it is made to return to run inside the hollow body of tubular shape in loose turns around the axis, the extra length of the line being defined by the cross section of the opening of the turns.

Likewise, provision can be made for the sliding body to have a recess on the bottom side constructed as a cable channel for the line and to carry a switch whose connecting member is supported on the shaft. By means of the cable channel, the deviation of the line is facilitated and, in particular, it is achieved that the sliding body can slide practically unimpeded through the hollow body. The switch arranged on the sliding body is provided to disconnect the power supply for the lighting device when the body of the sun visor is in its rest position applied under the internal roof of the vehicle.

In order to simplify the manufacture of the sun visor, it is recommended that the conductive wires of the line provided for the remote control unit are connected in an electrically conductive manner with a coupling element arranged on the body of the sun visor and which in turn can be pair with the remote control unit. This coupling member can consist of a commercially available component.

Likewise, it can be conveniently provided that the shaft with the sliding body, the multi-wire line, the hollow body, the connection device and the coupling element form a pre-assembled standard unit complemented by a frame structure that serves to give rigidity to the body of the parasol and that has plug elements that fit into the ends of the hollow body. This standard unit can then be covered with foam or, as preferably provided, it can be arranged between the halves of a sun visor body made up of two helmets.

An example of embodiment of the invention is described in more detail below with the aid of the drawings, in which they show:

Figure 1, a general view of the sun visor,

Figure 2, a folded plan view of the body of the parasol according to figure 1 formed by two helmets ^Y

Figures 3 to 9, details of the sun visor and an assembly sequence.

The sun visor according to FIG. 1 is made up of a sun visor body 1 which has in the region of its upper longitudinal edge 2 a hollow tubular body 3 incorporated therein, in which a sliding body is housed in an axially displaceable manner.

ES 2 292 503 T3 containing a shaft 5. The sun visor also has a bearing pin 6 intended to engage in a counter bearing, not shown. The shaft 5 has an approximately L-shaped configuration, the long flange of which is received by the sliding body 4 and the short flange of which is received by a small tilt bearing block 7. The body 1 of the sun visor is usually arranged on the long flange of the shaft 5 in the position that can be seen in figure 1. So that the driver and front passenger of a vehicle can protect themselves against incident solar rays or other light sources, the body 1 of the sun visor is fixed to the body of the vehicle above the windshield and can be folded down until it is in front of the windshield or tilted towards a side moon. Furthermore, a displaceable arrangement of the body 1 of the sun visor is provided, indicated by the double arrow, on the long flange of the shaft 5. Up to this point, the new sun visor corresponds substantially to the construction of the sun visor according to document EP 0 499 020 B1, so it is not necessary to explain in more detail details of the sliding body 4 with clamping element 8 and of the locking and displacement mechanism.

The new sun visor also has a connection device arranged in the body 1 of said sun visor and provided with a switch 9, a remote control unit 10 and a line 11 comprising several conductive wires.

As can be seen in figure 2, the body 1 of the sun visor has a kind of two-shell construction. The hull halves 12, 13 may consist, for example, of foamed or injected foam material. After the assembly of the helmet halves 12, 13, the body 1 of the sun visor generally still receives an envelope of, for example, a decorative textile material. Between the hull halves 12, 13 are the functional elements of the sun visor, most of which have already been mentioned above. In figure 2 it can be seen that end caps 14, 15 are attached to the hollow body 3, which are part of a frame structure 16 that serves to give rigidity to the body of the sun visor and that can consist of plastic injected castings and sections of wire joined with these. In the end caps 14, 15 there are passage openings for the line 11, not shown in detail, and in the end cap 14 there is also a passage opening for the shaft 5.

The line 11 necessary for supplying current to the lighting device (not shown) and to the remote control unit 10 comprises several conductive wires, for example, as shown, three conductors 17, 18, 19. In assembly, the line 11 is first led through the hollow shaft 5 (figure 3), after which a male plug element (not shown) is attached to the projecting end of the short flange of the shaft for connection to the general electrical system. vehicle. On the long flange of the shaft, a closing ring 20 and a plug 14 of the frame structure 16 have been previously plugged. Subsequently, the line is guided through the sliding body 4, which locks onto the end region of the long flange of the shaft 5. In the sliding body 4 there is arranged a switch 9 whose connecting member 22 attacks the shaft 5 and interrupts the current circuit for the lighting device, not shown, as soon as said member comes to be applied in the area of ​​a flattening 23 of the axis. This application is provided in general when the body 1 of the sun visor is in its rest position applied to the internal roof of the vehicle. One of the lead wires 17-19, for example lead 19, is connected to switch 9 and led past it (Figure 4). Subsequently, the line 11 with the conducting wires 17-19 (figure 5) is made to return, and this line runs through a cable channel 24 of the sliding body 4 and then runs with loose turns 25 around the axis 5 (figure 7) to It then comes out again from the hollow body 3 and the end cap 14 in order to be made to return again with a path parallel to the hollow body 3. The free ends of the lead wires 17-19 are eventually connected to a microswitch 26 and through this they are also directly connected to a coupling element 30 for the remote control unit 10 which is fixed to the frame structure 16 (figure 8). The microswitch is provided when the sunshade body is equipped with a mirror 27 and a mirror cover slider 28 cooperating with the microswitch 26.

The standardized unit according to figure 8 is placed inside one half 12 of the body of the sun visor, as shown in figure 2, and is covered with the second half 13 of the body of the sun visor, which can be united with the first by middle of a film hinge. Eventually, the halves 12, 13 of the sunshade body can be glued to each other or fixed to each other in some other way. The fixing of the parts 12, 13 of the body of the sun visor can also be effected by means of a decorative material 29 with which the blank of the body of the sun visor is usually wrapped. After wrapping, the closing ring 20 is still sewn onto the end cap 14, thereby ensuring a clean seal.

By moving the body 1 of the sun visor along the long flange of the axis 5, the power supply for the remote control unit 10 is always conserved, since, thanks to the loose turns 25, sufficient spare material is available for the line 11. Therefore, the new sun visor is foldable, tiltable and movable and, in addition, it is equipped with a power supply that guarantees a power supply to the remote control unit in any position of the body 1 of the sun visor. A forced disconnection of a lighting device is also provided which also operates in a sliding lid open position.
