Description

sunroof

The invention relates to a sliding roof according to the preamble of claim 1, wherein under sunroofs within the meaning of the invention, both inside and outside guided sliding roofs are to be understood with at least one cover element as well as slatted roofs and folding roofs. Likewise fall under the term "sunroof" and sliding roofs.

From DE 40 02 278 C1, a sunroof is known in which the lid is connected in addition to the actuating mechanism with a safety device against loosening the lid of the motor vehicle. The safety device is designed in the manner of a safety rope or tether, which is permanently in communication with the cover and a body-mounted component. The safety device is designed as a flexible component, which stretches in the event of an accident and holds the lid on the vehicle. It is further mentioned that the securing device in the form of a flexible component can be movably arranged on a carriage relative to the guide rail of the sliding roof, in order to make the securing device movable during opening and closing of the sliding roof cover. The solution given addresses the problem of how a complete release of the lid can be prevented from the vehicle. However, no solution is disclosed, as in the case of an accident caused by high acceleration forces on the lid sudden displacement of the lid in the direction of travel relative to the vehicle can be prevented forward. Furthermore, it is disadvantageous in the proposed sunroof that additional parts are necessary to form the safety device, which can adversely affect the assembly costs and reliability. In addition, the proposed tethers, tethers or fishing nets adversely affect the visual appearance of such a sunroof, at least in the open state. In addition, the proposed flexible securing devices are subject to aging processes, which makes it necessary to protect the security devices. at regular intervals or at least check to ensure long-term reliability of the safety device.

From DE 197 56 020 a sunroof is known, which is equipped with a, in normal movements of the lid member between open and closed position inoperative, only in the event of an accident becoming effective braking mechanism, the cover element over one of the crash decelerates occurring acceleration forces dependent distance. For this purpose, attacks are proposed on the one hand, which are formed in a guide rail of a sliding roof and can meet against a guide carriage in the event of an accident. If there is an impact of the carriage on the stops in the guide rail, a deformation of the carriage or a deformation of the stops is sought, so that a braking of the lid of the sunroof takes place. Alternatively or additionally, it is proposed to introduce into the guide rail a firmly attached wedge-shaped brake pad against which, for example, a rear guide carriage of the sunroof mechanism can accumulate in the event of an accident and thus additional braking is generated. In this sunroof, it is necessary for the effectiveness of the proposed Abbrems- or anchor devices that the sunroof cover in the event of an accident, which has the breakage of the mechanical connection between the carriage and the drive cable, almost unbraked over almost the entire closing movement relative to Guide rail moves. Only at the end of the intended travel path, the attacks come to effect and ensure a deceleration of the lid. The reason for this is that both the stops and the wedge to be arranged to ensure normal operation outside the usual travel of the carriage, so that during normal operation, the movement of the carriage is not affected relative to the guide rail. In addition, the provision of the stops in the guide rail requires a complex processing of the guide rails usually produced as extruded profiles. Such steps are complex and expensive. Furthermore, the proposed brake wedge as a separate

Part can be used in a guide channel of the guide rail, which means a high installation cost. The object of the invention is to provide a sliding roof, which avoids the disadvantages explained above and is also inexpensive and easy to produce. A further object of the invention is to provide a deceleration or mounting a lid of a sliding roof relative to the vehicle as soon as possible after the accident event and keep a free path of the sunroof cover relative to the vehicle until the effectiveness of the safety devices as low as possible or avoided. Another object of the invention is to make as slow as possible to limit the component loads braking or catching the lid, while avoiding sudden loads. Furthermore, it should be prevented that the sunroof cover in an accident can be detached from the vehicle and thus pose a danger to other parties involved in the accident. In addition, damage to other, in particular adjacent components by an uncontrolled moving sunroof cover should be avoided as possible.

These objects are achieved with a sliding roof with the features of claim 1. Advantageous embodiments are specified in the subclaims.

According to the invention, it has been recognized that the drive cable or drive cables conventionally provided for the drive of sliding roofs, which are guided in guide grooves of guide rails, are sufficient to absorb tensile and / or compressive forces in the vehicle longitudinal direction, which in the event of an accident due to the acceleration forces act on a sliding roof cover, occur, are suitable. It is therefore proposed, in a sunroof a Abbremseinrichtung which acts on the sunroof cover to provide, which causes a wedging of a moving component in the guide rail, wherein at least one Verkeilungspartner, eg a Verkeilungselement also in the event of an accident, ie, for example, after a violent break mechanical operative connection between the drive cable and a drive slide with the drive cable, this comes tensile or compressive load in operative connection or is. Whether a drive cable is subjected to tensile or compressive stress essentially depends on its mounting position in the vehicle. Since drive cables are usually designed in the manner of a spiral cable, these have a certain longitudinal elasticity, so that at least in the high accident forces occurring compressing or stretching the drive cable is effected and thus in addition to the wedging operation in the guide rail, a deceleration in the longitudinal direction is effected by the drive cable.

In addition or as an alternative to the proposed braking device, a safety catch device is proposed which has at least two catch elements as catching device partners, which are decoupled during normal operation of the sliding roof and due to their geometric configuration and spatial arrangement in the event of an accident, i. e.g. in the event of a breakage of the mechanical operative connection between the drive cable and a drive slide forcibly coupling. According to the invention, during or after the positive coupling of the catch elements at least one of the catch elements directly or indirectly with a drive cable, this tensile or compressive operatively connected, so that the sunroof cover is held even after a break in the mechanical connection between a drive carriage and a drive cable in the vehicle longitudinal direction.

Both the proposed braking device and the proposed catching device can be realized alone or in particular in combination with each other in a sunroof. Especially with relatively large and heavy cover elements of a sliding roof, a combined application of the catching device and the braking device will be recommended.

As has been found to be particularly useful to connect one of the wedging elements of the Abbremseinrichtung in one piece and particularly resilient to the drive cable, which may be useful, for example in the form of encapsulation of a drive cable section, wherein the wedging element is formed integrally formed in the encapsulation.

It is advantageous to provide a second wedging element as wedging partner for the first wedging element, wherein the second wedging element expediently comprises a sliding jaw or a slide jaw carrier of an actuating and / or guiding slide. least the sunroof mechanism is. As a result, in particular, the number of components and assembly costs can be kept low, since a sliding jaw or a slide shoe carrier in normal operation serves as a guide element of a carriage and takes over a second function as a wedging element only in the event of a crash.

It has proven to be particularly expedient to arrange the first and the second wedging element adjacent to one another in normal operation, in particular adjacent to one another without play. This makes it possible, in particular, to avoid an unwanted free travel of the sliding roof cover, since the braking device begins to act immediately after damage or after a breakage of the mechanical operative connection.

Furthermore, it has proved to be advantageous to arrange the first and the second wedging means in normal operation with respect to their position invariable, i. E. in particular, that the first wedging device when opening and closing the

Sunroof lid is synchronously moved with the second Verkeileinrichtung, for example, on an actuating slide, so that it is ensured in any position of the sunroof cover or the actuating slide that the Abbremseinrichtung can act immediately.

In a further embodiment of the invention, at least one or both wedging elements are provided with energy-dissipating shearing elements in order to destroy part of the pulse energy of the sunroof cover by breaking the shearing elements by shearing off or shearing off the shearing elements in the event of an accident. This results in a significantly lower subsequent load on the braking device during wedging. For example, a sliding jaw of the carriage, which is usually made of plastic, act as such shearing element by the plastic element is destroyed when the wedging elements meet. The first wedging element can, for example, have an integrally formed shearing projection at the beginning of a sliding ramp, which is sheared off by the second wedging element, for example a sliding block carrier. It is also expedient to angled or cranked form the second wedging element in longitudinal section. On the one hand, this has the advantage that plugged-on sliding jaws can be fastened particularly well to the slide-shoe carrier of a slide. On the other hand, a wedging between the first wedging element and the sliding block carrier (second wedging element) takes place more effectively.

As an advantageous embodiment of the catching device of a sunroof according to the invention, it is expedient to form a first catching element of the catching device as a cover-fixed catching hook, which is designed, for example, integrated in a ceiling mount. This is achieved for example by a hook-like configuration of the peripheral contour of the lid holder in the relevant area.

Furthermore, it is expedient to arrange the second catching element on an actuating slide or to use a part of the actuating slide as a second catching element, which is connected to the first catching element e.g. cooperates on the lid holder. In this case, it is also useful to provide a stop on the carriage, which projects into the guide groove for a drive cable and in the event of an accident on the drive cable, this pressure-bearing, is supported. The stop of the carriage has no or only a small distance from the free end of the drive cable in normal operation. This ensures that in the event of an accident after the positive coupling of the first and the second catch element of the free travel of the drive and / or the guide carriage is minimized relative to the guide rail or even avoided.

Furthermore, it has proven to be expedient to provide the mechanical coupling of the drive cable with the carriage with a predetermined breaking point, so that in case of an accident a defined breakage of the mechanical connection between the drive cable and the carriage is ensured.

Furthermore, it has proven particularly useful as a second catching unit to use a guide roller of the carriage, which runs along or in a backdrop during normal operation. In the following the invention will be described by way of example of exemplary embodiments in the drawing. Show it:

Figure 6: a perspective view of a mechanism of a sliding cover according to the invention in the event of an accident.

An inventive sunroof 1 (Figure 1) has one or more with respect to an opening 2 in a direction 3 and opposite to the direction of travel 3 displaceable cover 4 for opening or at least partially releasing and reclosing the opening 2 in a vehicle roof 5. The cover 4 are in roof-fixed guide rails 6, mounted driveably movable.

In the following, a braking device for a sunroof according to the invention will be described with reference to FIGS. 2 and 3. To drive the cover 4, these are coupled via not shown levers and / or sliding guides with a drive carriage 7, which is mounted on sliding blocks 8 in a guide track 9 of the guide rail 6 in the direction of travel 3 and against this direction. The drive carriage 7 has a carriage base plate 10, on which for receiving the sliding blocks 8 laterally outgoing as a slide shoe carrier 11 projections are formed. On the slide shoe carrier 11 are sliding blocks 8, which are preferred are formed of a lubricious plastic, plugged. The slide shoe carrier 11 is angled in the direction of travel 3 or has a crank 12. In a guide groove (not shown), which is preferably arranged adjacent to the guide track 9 in the guide rail 6, a drive cable 12a is displaceably mounted. The drive cable 12a has at its one end portion 13 on a plastic extrusion 14, in which the end portion 13 of the drive cable 12a is embedded. To the plastic extrusion 14, a cam plate 15 is formed, which extends through a slot (not shown) of the guide groove (not shown) for the drive cable 12a in a region between two sliding blocks 8 a longitudinal side of the drive carriage 7 and has a driving pin 16, which in mounted state in a corresponding driver opening 17 is seated in the carriage, so that a positive coupling of the drive carriage 7 is realized with the drive cable 12a at least in the displacement directions of the carriage 7 in the guide rail 6. In a region between two sliding jaws 8 adjacent in the direction of travel 3, the driver plate 15 has an integral with the driver plate 15 sliding ramp 18, which acts as a first wedging element of the braking device. The sliding ramp 18 runs in normal operation of the sliding roof 1 together with the sliding blocks 8, moved along with them, in the guide track 9 of the guide rail 6. The sliding ramp 18 has a forward direction in the direction of travel 3 thickened end 19 and a rear in the direction of travel 3 tapered end 20th Between the tapered end 20 and the adjacently disposed sliding jaws 8, the sliding ramp 18 has, as a shearing element 21, a projection extending vertically from the driving plate 15, which extends approximately to the level of the thickened end 20 of the sliding ramp 18 or slightly below. The sliding ramp 18 together with the shearing element 21 preferably fill the free space between two sliding jaws 8 which are adjacent in the longitudinal direction (direction of travel 3). A free surface 22 of the sliding ramp 18 forms a sliding surface in the event of an accident, to which the one in the direction of travel 3 lies behind Sliding ramp 18 arranged sliding jaws 8 and its slide shoe carrier 11 runs.

In the case of an accident, high acceleration forces are introduced into the carriage 7 by the lid 4 via coupling links, not shown, which results in the breakage of the driving pin 16 and thus decoupling of the mechanical operative connection between the drive cable 12a and the carriage 7 can lead. In such a case, the carriage could shift together with the lid 4 due to the high acceleration forces relative to the guide rail 6 abruptly in the direction of travel 3 forward, which by the Abbremseinrichtung 18, 11; 8 is prevented.

In the case of an accident cause the high acceleration forces on the carriage 7 after breaking the driving pin 16 that the rear in the direction of travel sliding 8 moves against the shear element 22, which is sheared by the high forces in the vehicle longitudinal direction (direction 3). As a result, kinetic energy (momentum) of the cover 4 is reduced and the free surface 22 for the emergence of the sliding jaw 8 and the Gleitbackenträgers 11 released. Since the sliding block 8 is formed of a soft plastic, this is destroyed during or even before the shearing off of the shear element 22, which also energy is dissipated. The sliding block support 11 can thus move relative to the sliding ramp 18 in the direction of travel 3, wherein the sliding block carrier slides on the free surface 22 and wedged in the guideway 9 of the guide rail 6 supporting due to the wedge-shaped configuration of the sliding ramp 18 on boundary walls 23 and on the sliding ramp 18 ,

As a result, a strong increase in friction is achieved, so that a deceleration of the drive carriage 7 takes place together with the cover 4. Since the sliding ramp 18 is constantly in normal operation in the space between two adjacent sliding blocks 8 and moved in each position of the sliding roof 1 with the drive carriage 7, in the event of an accident, the braking device can develop their effect immediately or immediately after the accident event. Thus, an unwanted, unbraked free travel of the cover 4 relative to the vehicle roof 5 is avoided.

Furthermore, during the braking operation or during the wedging process, the sliding ramp 18 is supported on the drive cable 12a via the driver plate 15, it is ensured that the slide ramp 18 provides sufficient resistance to ensure shearing off of the shear element 22 and subsequent wedging. In this case, the drive cable 12a also acts decelerating and / or shock-absorbing, since the drive cable 12a is usually formed as a spiral wire is, which has at least for high forces occurring in the event of an accident over a certain longitudinal elasticity, so that a compression of the drive cable 12a also has a shock-reducing effect. In the event of an accident, the sliding jaw 8 is also destroyed or cut or shattered when the sliding jaw carrier 11 strikes the shearing element 22, so that the sliding jaw 8 also acts as a shearing element for absorbing energy in such a case.

In the following, a catching device of the sunroof 1 according to the invention will be described with reference to FIGS. 4 and 5. The catching device has, as the first catching element, a catching hook 30, which is designed to be integrated in a lid holder 31, in particular integrated in its circumferential contour. The cover holder 13 is connected via a sliding link 32 with the drive carriage 7 in connection, wherein sliding portions 33 engage around the slide link 32. Furthermore, the slide link 32 cooperates with a guide roller 34, on which a lower side 35 of the slide link 32 rolls. The guide roller 34 acts, as will be described below, as a second catch element of the catcher. The drive carriage 7 has the carriage base plate 10 on which - as described above - sliding blocks 8 are arranged. The sliding jaws 8 run - as also described above - in a guide track 9 of a guide rail 6. Furthermore, the drive cable 12a is present, which has in its end region 13 the Kunststoffumsprit- tion 14, the driver plate 15 and a driving pin 16. The driving pin 16 cooperates with the driving opening 17 of the carriage 7. The carriage base plate 10 has at its rear end in the direction of travel 36 as a stop arm 37, which protrudes in normal operation in the guide groove of the drive cable 12a of the guide rail 6 and spaced at a distance d in the direction of travel 3 behind the free end of the drive cable 12a is. The distance d preferably has a dimension of a few millimeters up to a few centimeters. In particular, a distance d has proven to be in the range between 2 mm and 25 mm. In some applications, however, it may also be expedient to choose the distance smaller than 2 mm, in particular equal to 0 mm, as far as the tolerance installation conditions permit. In the case of an accident, the lid 4 (not shown in Figures 4 and 5) moves together with the lid holder 31, with which it is firmly connected, in the direction of travel 3 forward, the carriage 7 stops first. The guidance of the cover holder 31 relative to the carriage 7 via the sliding sections 33 and the sliding backdrop 32 causes the first catching element (the catching hook 30) and the second catching element (the guide roller 34) to be forcibly moved toward one another and forcibly after a distance s engage and thus positively coupled. After the positive coupling of the two catch elements 30, 34, the cover pulse is abruptly transmitted to the carriage 7, so that it comes to the breakage of the driving pin 16, which causes a mechanical decoupling of the carriage 7 from the drive cable 12a. From this point on, the lid 4, together with the lid holder 31 and the carriage 7, moves back the free distance d and thus moves relative to the drive cable 12a until the stop 37 comes into contact with a free end 34 of the drive cable 12a. The residual pulse of the lid 31, the lid holder and the carriage 7, which is still present, is supported by the stop 37 on the drive cable 12a under pressure load. Since the drive cable 12a is usually formed as a spiral cable, it is at least to some extent compressible in case of accidental forces in its longitudinal direction, so that a relatively gentle, impact-free interception of the cover pulse occurs. Thus, an indirect support of the cover 4 is achieved on the drive cable 12a.

So that a defined breaking of the driving pin 16 takes place at a certain shearing force, it may be expedient to fasten the driving pin 16 via a predetermined breaking point to the driving plate 15 of the drive cable 12a.

FIG. 6 shows an operating state of the catching device in the event of an accident. The driving pin 16 is broken and the driving opening 17 is exposed. The catch hook 30 is forcibly coupled to the guide roller 34, so that a mechanically strong, positive connection between the lid holder 31 and the cover 4 attached thereto relative to the carriage 7 takes place. In the illustration according to FIG. 6, the carriage 7 has already carried out a relative movement in the direction of travel 3 relative to the drive cable 12a, so that the slide shoe carrier 11 which is in the direction of travel 3 is 11 is already at least partially above the driving plate 15 of the Kunststoffumsprit- tion 14 of the drive cable 12 a is arranged. In this position, the stop 37 is in contact with the free end 38 of the drive cable 12a and is supported on this.

Depending on the structural design of the sunroof 1 according to the invention, in particular with a cover of higher weight, it may be particularly advantageous to provide the braking device, which has been explained by way of example with reference to FIGS. 2 and 3, with the catching device which has been explained by way of example with reference to FIGS. 4 and 5 combine so that the positive effects of both institutions cumulate.

By an inventive sunroof 1 of the impulse of a sunroof cover 4 is effectively reduced in the event of an accident, in particular completely destroyed, so that destruction of other components is prevented by the lid 4 and an uncontrolled movement of the lid 4 is avoided relative to the vehicle. Furthermore, it is advantageous that both the braking device and the catching device manage without additional items and thus are easy to assemble and inexpensive to produce. Furthermore, it is advantageous that an effective braking of the sunroof cover 4 relative to the vehicle is made possible immediately after the accident or after only a very short time, so that unintentional free travel of the cover 4 is avoided.

In a further, not shown embodiment of a sunroof according to the invention, the lid by means of a lid holder and, for example, a thrust strut immovable with respect. The drive carriage is mounted. In such a case, it is sufficient to provide only the stop 37. The fishing hook 30 can be omitted. The stop 37 then acts as a first catch element and is forcibly coupled by overcoming the free path d with the free end 38 of the drive cable 12a, which acts as a second catch element in such a case, so that a deceleration of the lid takes place. In such a case, the first catch element (the stop 37) is coupled directly to the drive cable or comes into direct contact with it. This embodiment is also if subject of the invention and in particular also combined with the above-described Abbremseinrichtung.

The illustrated examples of the braking device and the catching device act in the event of an accident a pressure load, so a compression of the drive cable 12a. However, it is readily conceivable, for example in a reverse mechanical arrangement of the drive cable relative to the direction of travel or relative to the carriage, that in the event of an accident, a tensile load is exerted on the drive cable. In this case, the spiral wire-like drive cable acts as a tension spring and causes a gentle deceleration of the lid.
