Description

The invention relates to a sliding window for a vehicle, in particular a motor vehicle, with a fixed component and a movable component. The invention further relates to a vehicle, in particular a motor vehicle, with such a sliding window. The fixed component and / or the movable component is in particular a window. It is possible that a plurality of movable components or windows are provided in a fixed component or window. The one or more movable components or windows are preferably displaceable. The sliding window can be installed in a vehicle door or vehicle door. However, it can also be part of the vehicle body.

Sliding windows, in particular flush sliding windows, are manually operated in previously known embodiments. In the known embodiments, the movable component must first be moved from the closed position into the vehicle interior. Then it can be moved behind the fixed component, this movement can take place substantially parallel to the fixed component.

A sliding window according to the preamble of claim 1 is known from DE 199 09 088 A1 or the US4920698 A1 known.

The EP 0 968 862 A2 discloses a sliding window for a motor vehicle with a fixed component and a movable component.

From the US 4,920,698 A a sliding window for a motor vehicle with a fixed component and a movable component is known, wherein on the fixed component, a drivable pinion is rotatably mounted and on the movable member, a rack, in which the pinion engages is provided.

The object of the invention is to allow for a sliding window of the type specified an aligned closed position of the motor-driven sliding window.

According to the invention, this object is solved by the features of claim 1. On the stationary component, a drivable pinion is rotatably mounted, which engages in a toothed rack, which is provided on the movable member. As a result, the sliding window can be driven by a motor.

The rack is designed as a tooth curve.

The movable member is substantially flush with the fixed member in the closing position of the sliding window. As a result, a particularly appealing appearance is achieved.

According to the invention, the fixed component has one or more guide rails.

In the guide rails or the guide grooves or other guide elements or guideways are provided for existing on the movable member bolts or other guide elements. Preferably, the bolts or other guide elements are removable.

The drivable pinion is rotatably mounted in the guide rail.

According to the invention it is provided that the rack or tooth curve has a portion for the movement of the movable member along the fixed component. This movement can take place in a plane substantially parallel to the stationary component, preferably on the inside of the stationary component.

According to the invention, the rack or tooth curve has a section for the movement of the movable component to the closed position. Preferably, this movement leads out of the plane that is substantially parallel to the stationary component. It preferably guides the movable component into a plane which runs essentially parallel to the stationary component. The mentioned section of the rack or tooth curve also serves for the reverse movement, ie for the movement from the closed position to the open position.

Advantageous developments are described in the subclaims.

Preferably, the pinion by a motor, in particular an electric motor, can be driven. It is advantageous if the motor is a geared motor. The pinion can be driven directly by the motor. However, it may also be indirectly driven by the motor, for example via a shaft, a flex shaft, a belt drive, a chain drive or a cable or the like.

According to a further advantageous embodiment, the guide grooves extend parallel to each other. In particular, the guide grooves are aligned with each other.

It is advantageous if the guide rails are made as an extruded profile. This is particularly advantageous when the guide grooves are aligned. For certain size ratios of the movable member, the guide rail may be designed such that the guide grooves are aligned. In this case, the guide rail is advantageously produced as an extruded profile, which is cost-saving, especially for small quantities.

In certain cases, it may be advantageous to manufacture the guide rails as hybrid components in shell construction.

According to a further advantageous embodiment, the rack or tooth curve is integrated into the extrusion coating, in particular plastic encapsulation, of the movable component. The rack or tooth curve may be inserted into the encapsulation of the movable component, so be designed as an insert. However, it is also possible to inject the rack or tooth curve directly. In this solution, the encapsulation including the rack or tooth curve is injected in one part. The encapsulation can be designed as a one-component injection molding or as a two-component injection molding.

According to a further advantageous development, a pinch protection is provided. The anti-jamming can be done by a motor control, for example, by changing the current consumption of the electric motor at certain path segments, by a sensor, in particular a Hall sensor; be determined. Instead or in addition, the anti-jamming can be done by contacting seals, the contact with an obstacle, such as a pinched finger or a pinched hand, turn off the engine or switch in the direction. The anti-trap protection can also be realized instead or additionally by an optical sensor in combination with the motor control.

It is advantageous if the motor or gear motor has a self-locking. The motor or geared motor can be connected to the movable component via mechanical elements. At this point, a self-locking can be realized. Due to the self-locking in the motor or geared motor or the mechanical elements with which the motor or geared motor is connected to the movable component, it can be achieved that the movable component is reliably held even in case of operating conditions, especially when driving, in any position.

The invention further relates to a vehicle, in particular a motor vehicle, with a sliding window according to the invention, wherein the vehicle or motor vehicle according to the invention is characterized in that the fixed component with the surrounding vehicle part is substantially aligned. The sliding window is thus used flush with the outside in the vehicle part, for example in a vehicle door, a vehicle door or a body part. This is particularly advantageous when the movable member is aligned with the fixed component in the closed position of the sliding window. In this case, the movable member, the fixed member and the surrounding vehicle part appear as a single, flush surface, which gives a particularly appealing appearance.

In Fig. 1 the middle portion of a guide rail 1 is shown, which is fixed to a fixed component, namely a fixed window, a motor vehicle. The guide rail 1 is manufactured as an extruded profile with inserts. It has a first guide groove 11 and a second guide groove 12, each extending in the longitudinal direction of the guide rail 1 and which are aligned with each other. The right end of the first guide groove 11 and the left end of the second guide groove 12 are spaced from each other. In the region of this distance, a recess 130 is provided in the guide rail 1 between the guide grooves 11, 12, in which a pinion 3 is rotatably mounted. The pinion 3 comprises a circumferential ring gear 4, which protrudes in the mounted position from the recess 130 upwards, and a bolt 5 which is rotatably mounted in the recess 130. The bolt 5 is further driven by an electric motor (not shown in the drawing). The electric motor may be attached to the guide rail 1 or another part of the fixed component or another part of the vehicle.

On the movable member, which is designed as a movable window (not shown in the drawing), a rack is fixed, which is designed as a tooth cam 2 and which has a toothing 6 and two guide pins 21, 22. The tooth curve 2 can be integrated into the encapsulation of the movable component. The first guide pin 21 engages in the first guide groove 11, the second guide pin 22 engages in the second guide groove 12 a. Further engages in the mounted state of the ring gear 4 of the pinion 3 in the teeth 6 of the tooth curve 2 a. The bolts 21, 22 are removable.

The guide grooves 11, 12 each have a first section 15, 16 and a second section 13, 14. The first sections 15, 16 are rectilinear. They extend in the longitudinal direction of the guide rail 1. The second sections 13, 14 extend at an angle of about 45 ° to the first sections 15, 16. Duch the first sections 15, 16, the tooth curve 2 and with it the movable member along the fixed Component moves. This movement takes place in one Plain held, which is substantially parallel to that of the fixed component and which lies on the inside of the fixed component.

The second sections 13, 14 serve to guide the toothed curve 2 and with it the movable component out of this plane into the closed position, in which the outer surface of the movable component is substantially flush with the outer surface of the stationary component.

Correspondingly, the toothing 6 of the toothed curve 2 has a section 17 which extends in the longitudinal direction of the guide rail 1, and a section 18 which extends at an angle of approximately 45 ° thereto. The toothing 6 is a straight toothing. It can also be designed as helical toothing, which entails a higher manufacturing outlay, which, however, increases the smoothness, reduces the noise formation during operation and reduces the mechanical load and thus the service life can be increased. In the embodiment according to Fig. 1 . 2 and 3 the tooth curve 2 is closed by a circumferential web 19. The circumferential ridge 19 extends parallel to the toothing 6 of the toothed curve 2 and at a distance thereto, wherein the distance substantially corresponds to the diameter of the ring gear 4 of the pinion 3.

In Fig. 4 a modified embodiment is shown, in which the tooth curve 2 'is formed open. Here the missing web 19 is missing.

The portion 17 of the toothing 6 is used for the movement of the movable member along the fixed component. The portion 18 of the toothing 6 serves for the movement of the movable member in the closed position.

The electric motor, which is designed as a geared motor, can drive the pinion 3 directly. However, it can drive the pinion 3 also indirectly, for example via a flexible shaft, a fixed or flexible threaded member or a rack or a toothed belt. The movement of the moving component is determined by the guide grooves 11, 12 in the guide rail 1, in which the guide pins 21, 22 slide.

According to the embodiment according to the invention Fig. 1 to 3 and in the variant Fig. 4 have the teeth of the toothing 6 of the tooth curves 2, 2 'in the horizontal direction and extends the axis of rotation of the ring gear 4 of the pinion 3 in the vertical direction. In the non-inventive embodiment, the in Fig. 5 to 8 is shown, in contrast, have the teeth of the toothing 6 'of the rack 23 in the vertical direction and extends the axis of rotation of the ring gear 4' of the pinion 3 'in the horizontal direction. The guide rail 1 ', which is fastened to a stationary component, namely a fixed window, of a motor vehicle, has a first guide groove 11' and a second guide groove 12 'which extend in the longitudinal direction of the guide rail 1' and which are parallel to one another and from one another are spaced. The first portion 15 'of the first guide groove 11' is rectilinear. This is followed by a second section 13 ', which is curved towards the left end of the second guide groove 12'.

In the region of the left end of the second guide groove 12 ', a recess 33 is provided in the guide rail 1', in which a pinion 3 'is rotatably mounted about a horizontal, transversely to the longitudinal direction of the guide rail 1' extending axis. The pinion 3 'comprises a peripheral ring gear 4', which is formed as a straight-toothed spur toothing. Instead of a straight toothing and a helical toothing can be provided, which brings the advantages explained above with it.

The ring gear 4 'engages the toothing 6' on the rack 23, which is fixed to the underside of the movable member 24, namely on the frame of a movable window for a motor vehicle.

The pinion 3 'is driven by a geared motor 25, which is provided below the guide rail 1 and whose output shaft is a worm 26, which engages in the ring gear 4 'of the pinion 3', to a horizontal, in the longitudinal direction of the guide rail 1 'extending axis drives.

On the underside of the frame of the movable member 24 there is a bore for a pin 27 which is provided on a Umlenkhebehl 28 having a base plate 29 and two of this downwardly projecting, spaced guide pins 30, 31. In the assembled state, the guide pins 30, 31 are in the first guide groove 11 '. At the other end of the frame of the movable member 24, a corresponding guide member is present (not shown in the drawing). The portions 15 ', 13' of the guide groove 11 'are designed such that the movable window 24 is aligned in the closed position with the fixed window and that it moves when opening the window from this closed position in a direction toward the interior of the vehicle and then moved parallel to the fixed window. During the movement of the movable window 24 out of the plane of the fixed window and into this plane, ie during the movement in a direction indicated by the double arrow 32, horizontal direction transverse to the vehicle longitudinal axis, the rack 23 also executes this movement. The rack 23 slides over the ring gear 4 'of the pinion 3' in the off FIGS. 7 and 8 apparent way. To compensate for this movement, the width of the toothing 6 'is greater than that of the ring gear 4', to ensure that the ring gear 4 'at all positions of the movable member 24 with the teeth 6' is engaged. The width of the toothing 6 'corresponds to its path in the direction 32, the in the transfer of the movable member 24 from the closed position according to Fig. 7 in the open position according to Fig. 8 is covered.

The fact that the movable member is driven in the manner described, many components can be omitted, which are required in a manual operation of the movable member. Furthermore, the further advantage can be achieved that less space is needed in the field of view and no covers for the handle mechanism are required, which benefits the perceived value of the sliding window. Another advantage that can be achieved with the invention, is that higher closing forces than in comfortable manual operation can be achieved. As a result, the tightness of the sliding window can be increased, in particular in "flush sliding windows", in which the movable component is aligned in the closed position with the stationary component. Another achievable advantage is the increase in comfort by simple key operation of the window, possibly from different position from the vehicle and also by a possible remote control, in particular a radio remote control or infrared remote control.
