Description

Vehicle window opening system

The invention relates to a vehicle window opening system for motor vehicles, which operates in its design with only one electric drive at least one movable vehicle window and at least one movable shading element.

Previously known vehicle window opening systems have in their function only the task of opening or closing a vehicle window. To prevent jamming of objects or limbs, anti-pinch protection can be used, which detects the dangerous situation and can stop and / or reverse the movement of the vehicle window, known from DE 198 36 705 C2. For the comfort of vehicle occupants shading systems are installed in high-quality vehicles, which protect against intense solar radiation and / or represent a visual or glare protection. These shading systems known from DE 202 14 713 U1 are to be operated manually or have a further electric drive which actuates the shading element. In contrast, inexpensive motor vehicles generally have no shading systems. In these vehicles often shading elements are glued to the movable vehicle window. Here are used to fasten suckers, which allow easy installation. However, the functionality of the window pane is restricted.

Likewise, from the prior art, a combined drive unit is known, which is described in DE 203 07 885 U1, in which by means of a motor, a door lock and an aggregate, for. B. a window regulator, operated. Various designs of vehicle window opening systems for motor vehicles are known from the prior art. About a crank or an electric drive, a movable vehicle window is fully or partially opened or closed. In DE 198 59 527 B4 is a Windows for motor vehicles described which comprises a means of a cable along a guide rail movable driver.

Furthermore, shading systems with a movable shading element are known from the prior art, which must be manually operated or have a separate electric drive. Since the movable vehicle window and the movable shading element can be actuated by separate drives, one can speak of independent movements.

Furthermore, solutions are known in which a shading element is mounted on a vehicle window.

The present invention is therefore based on the object to provide a vehicle window opening system for motor vehicles, which is equipped for actuating at least one movable vehicle window for opening / closing a window opening, as well as for actuating at least one movable shading element for opening / closing with only one electric drive. Furthermore, the invention is based on the object to provide a vehicle window opening system for motor vehicles, wherein the actuation of at least one movable vehicle window is independent and / or dependent on the operation of the at least one movable shading element. To increase the comfort of the vehicle window opening system manual actuation of the shading element should be avoided. At the same time weight, installation space and costs are to be saved by the use of only one electric drive. In order to couple the common electric drive in the drive element of the window regulator mechanism or the drive element of the mechanism for a shading element, a corresponding switching element is provided.

This object is achieved by a

Vehicle window opening system for motor vehicles solved, which is characterized in that at least one movable vehicle window and at least one movable shading element, which are each independently and / or independently movable in the intended opening area, are actuated with only one electric drive. Manual operation of the shading element (s) is not required. For the Diverting the energy from the electric drive for selectively actuating the at least one movable vehicle window or the at least one movable shading element, a switching element is provided.

This object is achieved by a second vehicle window opening system according to the invention for motor vehicles, which is characterized in that at least one movable vehicle window and at least one movable shading element, which are each dependent on each other in the intended opening area movable, are actuated with only one electric drive. Manual operation of the shading element (s) is not required. For the forwarding of the energy from the electric drive for selectively actuating the at least one movable vehicle window or the at least one movable shading element, a switching element is provided, which forwards the kinetic energy of the drive via a mechanical positive sequence. The kinetic energy is supplied to one component while the other component is not supplied with kinetic energy and is in a blocked position. In a preferred embodiment of the invention, the forwarding of the kinetic energy is effected by a planetary gear. The switching and blocking takes place by the interaction of a counting wheel with a locking bolt. Since the movable vehicle window and the movable shading element are operated by a mechanical forced operation by switching and blocking, one can speak of a dependent movement.

The object is achieved by a third vehicle window opening system according to the invention for motor vehicles, which is characterized in that at least one movable vehicle window and at least one movable shading element, which are each dependent on each other in the intended opening area movable, are actuated with only one electric drive. Manual operation of the shading element (s) is not required. For the forwarding of

Energy from the electric drive for selectively actuating the at least one movable vehicle window or the at least one movable

Shading element is a locking / coupling mechanism provided, which forwards the kinetic energy of the drive via a mechanical forced operation. The kinetic energy is supplied to a component, while no kinetic energy is supplied to the other component and is in a blocked position. Since the movable vehicle window and the movable shading element are operated by a mechanical forced sequence by means of locking and coupling, one can speak of a dependent movement sequence.

The invention has the advantage that a vehicle window opening system, in particular for motor vehicles, with at least one movable vehicle window, a movable shading element, a common drive for the movable vehicle window and the movable shading element and a switching element, characterized in that the energy transfer of the kinetic energy of Drive can be done either on the movable vehicle window or the movable shading element.

The invention has the further advantage that the kinetic energy is transferred from the drive by means of the switching element to the movable vehicle window or the movable shading element.

Another advantage is that the switching element is electromagnetically switchable.

Advantageously, the switching element is spatially assigned to the common drive. A particularly compact solution results when the common drive and the switching element are formed as a structural unit, for. B. summarized in a common housing.

It is advantageous if the common drive and the switching unit are designed as a structural unit.

An important advantage is that simple possible operating concepts can be used.

Advantageously, the traffic safety is increased, since disturbing influences caused by the manual operation, for. B. the shading element, can be avoided.

An economic advantage results from the weight reduction over the known from the prior art separate power window and Abschattungsmechanismen with two electric drives. It grows out of that a significant cost advantage over the known from the prior art window opening systems with the same benefit by a component reduction.

Another advantage is that the function of the window pane is no longer impaired by glued shading elements.

A particular advantage is that the improved functionality provides more safety and comfort.

In a particularly preferred embodiment, the window opening system for motor vehicles has at least one movable vehicle window and at least one movable shading element, which can be moved completely and / or partially independently of one another over the entire opening area provided in the vehicle door with only one electric drive.

It is also advantageous, depending on where the common drive and the associated switching element are arranged spatially in the vehicle door, to provide corresponding transmission elements which forward the kinetic energy of the common drive from the switching element to the drive wheel for the vehicle window or to the drive wheel for the shading element ,

Advantageously, such transmission elements spindles, gears, gear segments, cables or other suitable elements known per se. It is advantageous if the window mechanism itself is formed in a known manner as a cable window lifter, scissor window lifter etc. It is irrelevant whether the window lifting mechanism is designed to be movable via one or more guide elements. Advantageously, the electric drive and the switching element are controlled and controlled by an electronic control unit. In the control unit also signals from limit switches, sensors, etc. can be evaluated and converted into control commands. So z. B. by certain signals the anti-trap devices for window lift mechanisms and mechanisms for shading elements a drive shutdown or reverse rotation can be triggered.

In further particular embodiments, the switching element can also be structurally positioned separately from the drive. It is irrelevant at which point the switching of the kinetic energy of the common drive is done either in the window regulator mechanism or the mechanism for the shading element.

Fig. 1 shows a schematic representation of the combined window regulator and shading mechanism according to the invention. For example, is on the

Shell of a vehicle window 18 of a motor vehicle, a schematically illustrated and generally denoted by the reference numeral 5

Power window mechanism and a schematically illustrated and generally designated by the reference numeral 6 mechanism for a shading element attached. On both mechanisms 5 and 6, an electric drive 3 is arranged, namely a conventional window motor.

Directly on the electric drive 3, a switching element 4 is attached.

In the first switching position, the switching element 4 transmits the kinetic energy of the electric drive 3 to the drive wheel for the vehicle window 7 of the window regulator mechanism 5. The cable for the vehicle window 8 then transmits the kinetic energy further to the movable vehicle window 1, which is guided in two guide elements 13 becomes.

In a second switching position, the switching element 4 transmits the kinetic energy to the drive wheel for the shading element 9 of the mechanism for the shading element 6. The cable for the shading element 10 then transmits the kinetic energy further to the movable shading element 2, which is also guided in the guide elements 13 becomes. Fig. 2 shows a schematic sectional view of the switching element of Fig.1. A drive shaft 11 extending from the electric drive 3 is axially displaceable in engagement with the hub 4c, which carries the drive wheel 4d. The hub 4c is by a spring 4b in the illustrated basic position biased towards the solenoid 4a. The hub 4c simultaneously forms the armature of the lifting magnet 4a and is mounted axially displaceable. In this basic position shown in Figure 2, in which the solenoid 4a is de-energized, the drive wheel 4d is in engagement with the drive wheel for the vehicle window 7. In this basic position is a power transmission from the electric drive 3 via the drive shaft 11, the hub 4c In the example shown, the drive wheel for the vehicle window 7 transmits the kinetic energy of the cable for the vehicle window 8 in the window regulator mechanism 5, while the drive wheel for the Shading element 9 does no work.

In the currentless basic position of the switching element 4 shown, the window regulator mechanism 5 is therefore actuated by means of the engaging drive wheel for the vehicle window 7.

By switching the solenoid 4a in the current state, the hub 4c is moved against the force of the spring 4b from the basic position in Figure 2 to the right in the second switching position. Thus, the drive wheel 4d is also moved into engagement with the drive wheel for the shading element 9 and provides a power transmission to the mechanism for the movable shading element 2 ago. In this switching position, the mechanism for the shading element 6 is actuated.

The transmission of kinetic energy to the power window mechanism 5 is interrupted. In the respective positions thus either one or the other mechanism is always operated.

Fig. 3 shows the schematic representation of a further switching element 4 according to the invention with housing 4I in an overall view. The switching element 4 is designed in this particular embodiment as a planetary gear in a housing 4I, through which alternately either the rope for the vehicle window 8 or the cable for the shading element 10 can be actuated. This switching element 4 is driven by the drive 3 by means of the drive pinion 4e. Fig. 4 shows the schematic representation of the switching element 4 according to the invention with housing 4I in a sectional view. The kinetic energy of the drive 3 is transmitted via the drive pinion 4e to the planetary gears 4f and to the counting wheel 4i. From the planetary gears 4f, the kinetic energy is transmitted to the planetary gear receiver 4g. The further energy transfer then takes place from the Planetenräderaufnahme 4g on the rope for the shading element 10. The sun gear 4h is blocked in this position by the locking bar 4k. Thus, the rope for the vehicle window 8 is blocked as well. This blocking is done by a customer on the locking bar 4k, which prevents the transmission of energy in the receptacle on the sun gear 4h by positive locking. Within a structurally defined rotation of the counting wheel 4i, the actuation of the Planetenräderaufnahme 4g takes place. After a structurally defined rotation of the counting wheel 4i, the locking bar 4k is displaced along a groove in the housing 4I, and the pickup on the locking bar 4k is displaced from the receptacle on the sun gear 4h into the receptacle on the planetary gear receptacle 4g and blocks it and the cable for the shading element 10. In another constructionally defined rotation of the counting wheel 4i, the energy transfer from the planetary gears 4f to the sun gear 4h and thus to the rope for the vehicle window 8 takes place. By reversing the direction of rotation of the drive 3, the described procedure is also reversed.

Fig. 6 shows the schematic representation of the switching element 4 according to the invention without housing 4I in a further isometric view.

Fig. 7 shows the schematic representation of the switching element 4 according to the invention in an exploded view.

Fig. 8 shows a schematic representation of the combined window regulator and Abschattungsmechanismus invention by means of a latch coupling mechanism. The kinetic energy of the drive 3 is transmitted directly to a cable 22, which is guided in a slotted cable guide 21. The slotted cable guide 21 is guided by two guide rails 20 and operates there the latch coupling mechanism. In this case, the movable vehicle window 1 are actuated by the driver window 24 and the movable shading element 2 by the driver shading 23rd

Fig. 9 shows the schematic overall view of a locking Koppeimechanismus. Shown are the possible end positions of the driver window 24 and the driver shading 23. In the closing operation of the movable vehicle window 1, the driver window 24 in the

Closed position prevented by the stop window 20b on a further movement along the guide rail 20. The movable shading element 2 is shown in the open position.

10 shows an enlarged detail view of the latching coupling mechanism according to the invention as shown in FIG. 9. For a better view of the latch coupling mechanism, the guide rail 20 is shown in half. Through the slotted cable guide 21, a cable 22 is guided, on which a nub shadowing 22a is attached. The knob shadowing 22a includes a catch bolt shading 22b, which can be enclosed by the latching coupling element shading 23a. The latching coupling element shading 23a is biased by the spring detent coupling element shading 23b and is engaged in this illustration in the latching window for shading 20c. The driver shading 23 is connected to the slider shading 23c, which is slidably mounted in the guide rail 20. In this case, the driver shadowing 23, the slider shading 23c, the spring detent coupling element shading 23b and the latching coupling element shading 23a form a structural unit. The open position of the movable shading element 2 is limited by the driver shadowing 23, which is prevented at the stop shading 20a at a further movement along the guide rail 20 down. When the movable shading element 2 is to be closed, the knob shadowing 22a moves upward, the latching coupling element shadowing 23a encloses the catching bolt shading 22b and is moved out of the latching window shading 20c. Thus, the movable shading element 2 couples to the cable 22 and can be moved to the closed position.

At the upper end of the illustrated guide rail 20 is the latching Coupling element window 24a is opened, locked in the locking window, not shown window 2Od and the catch bolt window 22d, when the movable shading element 2 is closed, are moved freely with the knob window 22c along the slotted cable guide 21. The movable window 1 is fixed in this position by the stopper window 20b, not shown, and by the latching of the latching coupling element window 24a in the latching window, not shown, window 20d.

Fig. 1 1 shows the schematic view of the driver window 24 in an end position. Shown is the position of the driver window 24, which is prevented by the stop window 20b at a further operation and thus supports the latching process.

Fig. 12 shows the schematic detail view of the driver window 24 in the latched end position. In this position, the knob window 22c is freely movable upwards, since the latching coupling element window 24a, biased by the spring detent coupling element window 24b, is locked in the latching window window 2Od. The movable vehicle window 1 is fixed in this position.

Fig. 13 shows the schematic detail view of the driver window 24 in a coupled intermediate position. The movable vehicle window 1 is coupled here via a structural unit.

The structural unit consists of the driver window 24, the slider window 24c, the spring detent coupling element window 24b and the latching coupling element window 24a,

The latching coupling element window 24a encloses here the catch bolt window 22d with the cable 22 and the knob window 22c.

Fig. 14 shows an exploded view of a latch coupling unit. In this simplified schematic representation, the elements are represented individually. In the guide rail 20 shown in half, with the locking window window 2Od and the stop window 20b, the structural unit, consisting of the driver window 24, the slider window 24c, the spring latching coupling element window 24b and the latching coupling element window 24a slidably mounted , Likewise, the knob window 22c, the cable 22 and the catch bolt window 22d form a structural unit. To be led the cable 22 through the slotted cable guide 21st

Fig. 15 shows the schematic diagram of a possible starting position, wherein the movable vehicle window 1 and the movable shading element 2 are opened. The arrows indicate the direction of movement of the cable 22 for closing the movable vehicle window 1 and the movable shading element 2. Further possible positions until closing are described in FIGS. 15 to 17.

In this representation, it is shown in simplified form how the positions of the individual elements relative to one another are dependent on the positions of the movable vehicle window 1 and the movable shading element 2. The knob 22b connected to the cable 22, as well as the catch bolt window 22d are in coupling with the driver window 24. In contrast, are connected to the cable 22 knob shading 22a, as well as the catch bolt shading 22b not in conjunction with the driver shading 23rd , which is engaged in the guide rail 20 and thus fixes the movable shading element 2.

16 shows the basic representation of a possible position, wherein the movable vehicle window 1 is closed and the movable shading element 2 is open. From the starting position, as described in Fig. 15, it is shown here, as with the cable 22, the knob window 22c, and the catch bolt window 22d, the driver window 24 moves upward and thus the movable vehicle window 1 is closed. The further movement of the driver window 24 is stopped by the stopper window 20b, not shown. In this position, the latching coupling element engages window 24a in the latching window window 2Od. The nub shading 22a with the catch bolt shading 22b has been moved into the driver shading 23. The driver shading 23 is still engaged in the guide rail 20.

Fig. 17 shows the schematic diagram of a possible end position, wherein the movable vehicle window 1 and movable shading element 2 are closed. As a result of the further movement of the cable 22, the nub windows 22c and the catch bolt window 22d are guided out of the latching coupling element window 24a (not shown). The nubb shading 22a with the catch bolt shading 22b couple to the Driver 23, wherein this is disengaged from the guide rail 20, and move the movable shading element 2 in the closed position. To reopen the movable vehicle window 1 and the movable shading element 2, the direction of movement of the cable 22 shown in FIGS. 15 to 17 is reversed.

The invention has been described with reference to a particular embodiment. However, it goes without saying that changes and

Modifications can be made without departing from the scope of the following claims.
