Description

The invention relates to a power window switch for a motor vehicle with a pivotally mounted in a housing actuating element which actuates via an associated shift switching element switching contacts, which terminal contacts are assigned.

From DE 44 31 061 A1 discloses a stroke-slide switch, in particular for the lifting sunroof of a motor vehicle, known. The terminal contacts having housing is provided with a pivotable in neutral position or operation button on which a lever is attached, which acts on a sliding switch member. Pivotally movable, a rotary switching member is mounted on the sliding switching member, in which the lever of the actuating knob engages movable. The two switching elements go through a reset automatically into their original position and put the associated with them actuator button in its initial position. The restoring device is formed by a guide tube attached to the rotary switching element and supported by spring-loaded pressure sleeves, and by two projections which are injection-molded onto a base and project into the housing as well as recessed return pyramids. Under the action of a compression spring, the pressure sleeves become outward against the recessed return pyramids pressed in the projections, whereby after releasing the actuating button, the restoring device and thus also the switching elements assume their zero position. By pivoting or moving the actuating knob associated with the rotary and / or the shift switch member contact spring areas are brought to rest on an embedded in the base punched grid. The contact spring areas are dimensioned so that a larger number of current paths can be realized. With the stroke-slide switch to different motors are controlled, which have both a right and a left-hand rotation.

Furthermore, from DE 195 37 296 A1 a rocker switch device for a two-stage operating stroke is known, which is part of an operating unit for power windows of a motor vehicle having a pair of actuator plates below a longitudinal center line of a rocker switch. The actuating plates are coupled by means of elastic connecting arms and thus form an actuating member. Each Betärigungsplatte acts on two pressure switches, which are formed by a hollow projections having switching mat with disposed therein contact pieces and a base plate with the movable contact pieces associated fixed contact pieces. Upon actuation of the rocker switch this pivots about Trägerachsstummel a housing so that the actuated side of the rocker button moves down. This downward movement is transmitted via the associated actuator plate to the lower right and left-hand hollow projections of the switching mat. The projections are arranged so that due to different, acting torques first deformed the left projection and a circuit is closed by the contact of the contacts arranged here. After further downward actuation the rocker button and the right projection is pressed down by the actuator plate and another circuit closed. By releasing the rocker switch, the reset is the same, and the closed circuits are interrupted. The assignment of a rocker switch device for the control of electric windows holds the risk of unintentional operation. In this case, the closing of the window by accidentally pressing the rocker switch is particularly disadvantageous because it may cause injury to a person who is, for example, with one hand or with his head in the closing area of the window, arise

Another example of such a switch is e.g. from US-A-4,876,493.

It is therefore an object of the invention to provide an electrical switch, in particular power window switch for a motor vehicle, of the type mentioned, which excludes unintentional closing of the window, a tactile detection of the switch operation allows and by a compact design with the least possible number of components characterized by a reliable function.

According to the invention the object is achieved in that the actuating element is assigned in the printing direction for the downward movement of the window and in the pulling direction for the upward movement of the window each have a two-stage pivoting movement, wherein the actuating element deflecting means for a linear reciprocating motion of the sliding switching member applied, in each Direction successively actuated two switching contacts a keypad.

These measures prevent inadvertent closing of the window, since the actuation of the actuating element in the pulling direction is performed only very consciously. Of Furthermore, a tactile detection of the switch operation is made possible by the successive admission of two switching contacts of a switching mat. Possible variations with regard to the detectability of the switch operation result from a corresponding design of the mechanical resistance of the switching mat, which is determined by their strength and structural design. The application of deflection means for the linear movement of the switching member by the actuator allows a compact construction of the power window switch.

According to an advantageous embodiment of the invention, the deflection means comprise the free, T-shaped end of a web of the actuating element and a free end of the web receiving opening of the sliding switching member. As a result, no additional components that allow a corresponding deflection of the pivoting movement of the actuating element in a linear movement of the sliding shift member, necessary.

According to an alternative embodiment of the invention, the deflection means comprises a pivotally mounted in the housing, two-armed lever whose one arm engages with a T-shaped end in an opening of the sliding shift member and whose other arm is provided with horizontally opposed pins, the one from the actuating element molded fork are overlapped. The use of the reversing lever allows a variation of the pivoting movement of the actuating element, wherein the essential structure of the power window switch is maintained. As a result, it is possible for the manufacturer to produce the basic components in a large number and to adapt individual parts to be assembled according to requirements.

Preferably, the reversing lever on two horizontally opposed bearing pin, which engage in corresponding openings of the housing. Since both the lever and the housing are made by injection molding of plastic, the Lagerund is feasible without special manufacturing or assembly effort.

The reversing lever transmits forces during the pivotal movement of the actuating element on the sliding switching member and must have a sufficient stability for this purpose. Therefore, the bellcrank in the region of the bearing pin is expediently made thickened in cross section, and the arm of the bell crank associated with the actuating element is provided with reinforcing ribs.

To support the transmission of force during the pivoting of the actuating element of the actuating element facing arm of the reversing lever is preferably provided frontally with a recess at the bottom of a resilient tongue is formed, which is supported at the end of the actuator backlash. The play-free mounting of the train on the actuator also causes a positive shift feeling, since the actuator at this point travels no free travel. The resilient action of the tongue is adjustable inter alia by the depth of the recessed into the arm of the reversing lever recess and changeable by means of relatively simple tool adjustments.

Preferably, this is the T-shaped end of the web or of the reversing lever in cross-section circular or semicircular and arranged at a widened end of the sliding switching member Opening rectangular. Sonach is given the necessary freedom of movement.

Thus, on the one hand allows easy joining of the web or of the reversing lever and the opening of the sliding switching member and on the other sliding out of the web or the reversing lever from the opening of the sliding shift member in one of the end positions of the sliding shift member is preferably on the longitudinal sides of the opening on the outside respectively arranged two opposite reinforcing ribs which project slightly into the opening and between them receive the T-shaped end of the web or of the reversing lever.

Conveniently, two opposing spring arms are arranged on the longitudinal sides of the opening on the outside, which rest under prestress on the T-shaped end of the web or of the reversing lever. As a result, the web of the actuating element or the deflection lever is mounted without clearance in the opening of the sliding shift member and positively influenced the tactile shift sense, since no unnecessary free travel during pivoting of the actuating element must be overcome.

According to a development of the inventive concept, the shift shift member is formed substantially plate-shaped and mounted horizontally longitudinally displaceable between stationary guide webs. Furthermore, the sliding switching element on its upper side reinforcing ribs. Furthermore, the sliding shift member is located with its underside on a connecting bracket of two switching mats, and the top of the sliding switching member are Klipsnasen stationary Klipsarme associated with play. By this embodiment of storage is dispensed with the use of additional items. guide webs and Klipsarme are components of a base and are manufactured together with this by injection molding. Due to the approximately point-shaped support of the sliding shift member on the connecting bracket and its limitation upwards by the Klipsnasen the Klipsarme and the housing supporting reinforcing ribs, the friction losses are minimized in the longitudinal displacement of the sliding shift member. Furthermore, the assembly of the sliding shift member can be realized by simply clipping. The reinforcing ribs of the sliding switching member counteract a deflection of the same.

Conveniently, the sliding shift member is provided on its underside with two eccentrically offset longitudinal axis and mutually spaced actuating lugs, which act in each case on the switching contacts of the associated switching mat. The sliding switching element with the integrally formed actuating lugs is manufactured in a single operation and is therefore inexpensive to produce.

Preferably, each switching mat comprises two switching contacts in adjacent and spaced-apart domes, wherein the dome are covered in its upper region by a common actuating plate. Due to this arrangement, the shift switch for the actuation of each keypad requires only one actuation approach, as it acts via the actuator plate off-center on the switch contacts and actuated depending on the way first one of the switch contacts and then both switch contacts by depressing the dome. The domes are relatively close to each other, whereby the switch is made narrow, and are designed so that the tactile detection of the switching is ensured by the buckling of the dome by their operation.

In order to achieve a short length of the switch and a low installation costs, the switch contacts associated terminal contacts are recessed in a perpendicular to the longitudinal axis of the sliding shift member extending rib of a base of the housing. Furthermore, a respective switching mat is arranged with two horizontally arranged switching contacts on one side of the rib of the base. The admission of the terminal contacts is advantageously carried out by encapsulation.

So that the terminals outside the socket are protected from damage and errors in the connection of the switch are avoided, the terminal contacts are surrounded by a designed as a plug-coding connection collar.

To completely cover the installation opening of the switch in the motor vehicle and to allow an ergonomic switch operation, the top of the housing is covered by a panel with recessed trough, in which engages the actuator. The panel can be assigned to the housing by means of detachable connecting elements or molded onto the housing. The trough is arranged so that the actuating element of the switch can be easily engaged behind to actuate it in the pulling direction. Further, in each case a retaining spring is arranged for simplified mounting of the switch in the motor vehicle at the front and the rear of the housing. The retaining springs engage behind the upper edge of a mounting hole and thus ensure a secure fit of the switch.

It is understood that the features mentioned above and those yet to be explained not only in the combination given, but also in other combinations are usable without departing from the scope of the present invention.

To realize this Clip connections 7 is located in the region of the front side 8 of the housing 6 on an integrally formed on the housing 6, upwardly projecting collar 9 a Klipsnase 10, which is engaged behind by the lower edge of the panel 4. Further, in the region of the rear side 11 of the housing 6, there are two spaced-apart clip arms 12, which engage in corresponding clip openings 13 of the panel 4. The collar 9 has on its side surfaces 14 in the upper region in each case a Klipsnase 15 which form with lateral, circular Klipsöffnungen 16 of the actuating element 2 Klipsverbindungen 17. The clip connections 17 at the same time constitute an axis of rotation 18 around which the actuating element 2 executes a pivoting movement 19.

At the front 8 and back 11 of the housing 6, a retaining spring 20 is arranged centrally in each case, which is designed in the lower region U-shaped, so that it surrounds the lower edge of the housing 6. The fixation of the retaining springs 20 by means of Clip connections 21, wherein the housing 6 at the front 8 and back 11 each have a Klipsnase 22 which engages in a corresponding clip opening 23 of the retaining spring 14. The retaining springs 20 are used for fastening the power window switch 1 in an installation opening, not shown, of a motor vehicle. The housing 6 is associated with a base 24, on the upper side of which a collar 26 which can be introduced into the housing 6 and is formed in the region of the front 8 and rear 11 apertures 25 is integrally formed. The openings 25 serve as clearances for the holding springs 20 arranged in this area. A connection collar 27 is arranged on the underside of the base 24. To realize the clip connections 28, the collar 26 of the base 24 on each longitudinal side on two spaced Klipsnasen 29, which engage in associated Klipsöffnungen 30 of the housing 6.

The actuator 2 has on its rounded top symbols 31, which may be backlit by unillustrated, lichtemmitierenden elements. A downwardly tapering in its thickness web 32 is centrally formed on the underside of the actuating element 2 and in alignment with the circular clip openings 16. The width of the web 32 is made constant to the free end 33. The free end 33 of the web 32 is formed T-shaped, wherein the opposite legs have a circular or semicircular cross-section, and engages in a rectangular opening 34 of a arranged in the housing 6 shift switching member 35 a. On the longitudinal sides of the opening 34, two opposing reinforcing ribs 36 are arranged, which project slightly into the opening 34 and between them the T-shaped end 33 of the web 32 record. To compensate for the existing clearance between the reinforcing ribs 36 and the T-shaped end 33 of the web 32, a spring arm 37 is attached to each longitudinal side of the opening 34 between the reinforcing ribs 36, which bears against the T-shaped end 33 of the web 32 under prestress , The free end 33 of the web 32 and the opening 34 of the sliding switching member 35 form deflection means 38 in this embodiment.

The sliding shift member 35 is formed substantially plate-shaped with a constant thickness and has in the region of the opening 34 a broadening 39. All longitudinal sides 40 of the sliding switching member 35 are executed parallel to each other. The sliding shift member 35 is guided horizontally between stationary, each pairwise opposite guide webs 41 of the base 24. In the region in which the guide webs 41 rest on one of the longitudinal sides of the sliding shift member 35 whose end faces are provided with a radius 42. The vertical boundary of the sliding shift member 35 upwards by stationary, each pairwise opposite Klipsarme 43 of the base 24, the Klipsnasen 44 are assigned to the top of the sliding shift member 35 with play. If the upper side of the sliding switching member is provided with reinforcing ribs 45, the clip noses engage over the sliding switching member 35 in edge regions which are free of reinforcing ribs 45. Accordingly, the horizontal mobility of the shift switch member 35 is ensured to the extent necessary. The underside of the sliding switching member 35 has two actuating lugs 46 which are arranged eccentrically to the longitudinal axis 47 of the sliding switching member 35 and spaced from each other. The vertical boundary of the sliding shift member 35 down is on the one hand by a flexible connecting bracket 48 of two switching mats 49 and the others realized by paragraphs 50 in the upper region of the guide webs 41, whereby a vertical clearance compensation can be effected.

The two by the connecting bracket 48 coupled switching mats 49 are arranged opposite one another. Between the switching mats 49 there is a formed on the base 24 and aligned at right angles to the longitudinal axis of the sliding switching member 35 rib 51, in which a punched grid 52 is injected. The terminal contacts 53 of the stamped grid 52 protrude into the terminal collar 27 of the base 24. On each side of the rib 51, a web 54 is centrally located, which engages in an elongated hole-shaped opening 55 of the associated switching mat 49 and fixes it. Each switching mat 49 has two adjacent and spaced dome 56, each dome 56 receives a switching contact 57. The two domes 56 of each switching mat 49 are covered in their upper area by a common actuating plate 58. The two switching mats 49 with associated actuating plates 58 are located between the actuating lugs 46 of the sliding switching member 35 at right angles to its longitudinal axis 47. Each actuating lug 46 is provided in its area of contact with the actuating plate 58 with a V-shaped tip 59.

When pivoting the actuating element 2 of the power window switch 1 from the zero position 60 in the direction of pressure in a switching position first stage 61 is a left pivoting movement of the web 32 about the axis of rotation 18. The engaging in the opening 34 of the sliding shift member 35 and both by the reinforcing ribs 36 as well as held by the spring arms 37 T-shaped end 33 of the web 32 transmits this movement to the left on the sliding shift member 35. By the aforementioned deflection means 38, the rotational movement of the web 32 in a translational, the movement direction of the web 32 following movement of the sliding switching member 35 is transferred. The right operating projection 46 begins to act on the actuating plate 58 of the right-hand switching mat 49. Due to the arrangement of the actuating lug 46 outside the longitudinal axis 47 of the shift switch member 35 and the resulting leverage, acting on the dome 56 in the vicinity of the actuating lug 46, the largest torque, so that this kinks and the associated switching contact 57 closes a circuit on the lead frame 52 , By appropriate design measures, the process of buckling of the dome 56 allows a tactile detection of the switching position. In this switching position first stage 61, a not shown window motor is driven such that a motor vehicle window, not shown, moves slowly down. When you release the actuator 2, the dome 56 jumps back to its original position. The circuit is opened and the motor vehicle window remains in the position reached. Due to the restoring action of the dome 56, both the sliding switching element 35 and the actuating element 2 are returned to the zero position 60. If the pivoting of the actuating element 2 of the switch 1 from the zero position 60 in the pressure direction in a switching position of the second stage 62, close the already explained motion sequences. The right operating projection 46 begins to act on the actuator plate 58 of the right-hand switching mat 49 and brings the nearest him Dom 56 due to the acting torques first to buckling. The associated switching contact 57 closes a circuit on the lead frame 52. Since the switching position second stage 62, a larger left movement of the shift switching element 35 result has as the switching position of the first stage 61, begins after closing the first circuit of the second, at a greater distance to the actuating projection 46 arranged second Dom 56 buckling. The associated switching contact 57 closes another circuit on the lead frame 52. The switching operation of the second dome 56 is tactually perceptible. The thus controlled window motor moves the motor vehicle window quickly down to its final position. The provision of the actuating element 2 takes place after releasing the same due to the forces of the recessed dome 56th

In order to move the motor vehicle window upward, the pivoting movement 19 of the actuating element 2 in the pulling direction, in switching positions first 63 and / or second stage 64. The movements for actuating the right switching mat 49 are equivalent to those already described, but in the opposite direction.

In an alternative embodiment of the power window switch 1, the actuating element 2 is inserted into the trough 5 of the aperture 4 such that the upper edge 3 does not protrude beyond the aperture 4. Below the axis of rotation 18 performing the clip connections 17 around which the actuator 2 performs the pivoting movement 19, the same is provided by means of a voltage applied to the aperture circumferential seal 65, which prevents contamination of the switch interior.

To the actuating element 2, two opposing and mutually spaced forks 66 are formed, which serve to overlap horizontal pin 67 of a pivotally mounted in the housing 6 reversing lever 68. To facilitate assembly At the free ends of the forks 66 are provided chamfers 69 for the pins 67.

The reversing lever 68 is designed with two arms, wherein one arm 70 is provided with the pin 67 and another arm 71 has a T-shaped end 72 which is circular or semicircular in cross section and engages in the opening 34 of the sliding switching member 35. The pivoting movement of the lever 68 by means of two horizontally opposed bearing pin 73, which engage in corresponding openings 79 of the collar 9 of the housing 6. In the area of the bearing pin 73, the reversing lever 68 is made thickened in cross section. The pin 67 carrying, the actuating element 2 facing arm 70 of the reversing lever 68 is frontally provided with an arm 70 dividing recess 74. At the bottom of the recess 74, a resilient tongue 75 is integrally formed, which is supported without play by the actuating element 2. For this purpose, the actuating element 2 has correspondingly shaped projections 76. For stiffening the arm 70, respectively opposite reinforcing ribs 77 are provided.

The deflection means 78 are formed in this alternative embodiment of the reversing lever 68 and the opening 34 of the sliding switching member 35.

During the pivoting movement 19 of the actuating element 2 of the power window switch 1 from the zero position 60 in the pressure direction in a first-stage switching position 61 performs the T-shaped end 72 of the reversing lever 68 against the spring action of the tongue 75 is a rightward pivoting movement, the sliding switching member 35th follows. The transformation of the rotational movement of the reversing lever 68 in a translational movement the sliding shift member is effected by means of the deflection means 78. The left operating projection 46 begins to act on the actuating plate 58 of the left switching mat 49. As already explained, the closing of a circuit on the punched grid 52 takes place through the associated switching contact 57 in the buckling dome 56, wherein a tactile detection of the switching position is made possible by the design of the dome 56. Due to appropriate occupancy of the terminal contacts 53, a motor vehicle window is opened slowly. When you release the actuator 2, the dome 56 jumps back to its original position. The circuit is opened and the motor vehicle window remains in the position reached. Due to the restoring action of the dome 56 and the supporting action of the prestressed tongue 75, both the sliding switching element 35 and the actuating element 2 are brought into the zero position 60. In the switching position second stage 62 in the printing direction another circuit, as described above, closed on the lead frame 52 and the motor vehicle window opens quickly until it reaches its end position.

To close the vehicle window, the actuating element 2 is pivoted in the pulling direction, in switching positions of the first 63 and / or second stage 64. The subsequent movement sequences for actuating the left-hand switching mat 49 are equivalent to those already described, but of course in the opposite direction.
