Description

Title of the invention: Glass unit for a motor vehicle window

[0001] The invention relates to a glass unit for a motor vehicle window, which includes a first glass with an inner face oriented towards the vehicle's passenger compartment and an opposite outer face, with a guide element extending along a longitudinal side of the first face and intended to guide a second glass upwards and downwards.

[0002] Such a glazing unit is known from document EP 2 463 133 A1. The first glazing is surrounded by a frame having a multi-part profile with at least one secondary part as a flexible component. A receiving area for a screen element is provided on the frame, facing outwards from the body. A primary part is provided in the frame as a rigid component, which includes a U-shaped guide profile. This U-shaped guide profile is associated with a longitudinal edge of the glazing. The longitudinal edge, as well as the outer and inner faces of the glazing, are overmolded with a flexible component. The primary part is partially overmolded with the same flexible component.

[0003] EP 2 463 134 A1 also describes a glass unit. In this glass unit, a rigid component with a U-shaped guide profile is formed, aligned with the longitudinal side of the first glass pane, which surrounds both an area adjacent to the longitudinal edge on the inner face of the glass pane and on the outer face of the first glass pane. The rigid component, which has a U-shaped profile to form a guide element, is overmolded with a flexible component on its outer face as a guide element, the flexible components being in contact with both the outer and inner faces of the glass pane.

[0004] The invention aims to provide a window unit which includes a first window with a guide element disposed thereon for a window that can be moved up and down in it, wherein the disposition of the window that can be moved up and down relative to the first window is improved.

[0005] This object is solved by a glass unit in which the guide element is disposed, in particular fixed, on the inner face of the first glass pane or connected to the inner face of the first glass pane. This arrangement has the advantage that the guide element is more rigid, because a surface portion or a bearing portion of the guide element adjacent to the inner face of the first glass pane extends along the inner face of the first glass pane, thus forming a reinforcement for the guide element. Furthermore, this design offers the advantage of increased security against break-ins. In addition, it is possible to improve the visual appearance of the guide design between the first pane of glass and the sliding glass panel (moving up and down).

[0006] In particular, it is provided that the guide element is fixed exclusively to the inner face of the first pane of glass. The longitudinal edge between the inner and outer faces of the first pane of glass, as well as the outer face of the first pane of glass, are thus completely free and are not covered by the guide element and / or a component intended to connect the guide element to the first pane of glass.

[0007] According to an advantageous embodiment, a sealing element can be inserted into the guide of the guide element, along which the movable glass is guided upwards and downwards. This arrangement allows existing concepts for the sealing element to continue to be used for guiding the movable glass upwards and downwards.

[0008] It is advantageous to ensure that the up-and-down movable pane is aligned so as to overlap the inner face of the first pane. This simplifies sealing in the area between the first pane, i.e., the stationary pane, and the up-and-down movable pane. This pane unit is installed in an opening or recess in a vehicle door, with the first pane securely fixed to the body and the second pane able to be moved up and down by means of the window guide element in the door body.

[0009] It is further preferable that a sealing lip be disposed between the longitudinal side of the first pane facing the movable pane and an outer side of the movable pane. This sealing lip rests against the longitudinal side of the first pane and against the outer side of the movable pane. Preferably, the sealing lip has a stop or support that extends at least partially or completely over the thickness of the longitudinal side of the first pane. This sealing lip is preferably formed as a single piece on the sealing element. This provides, on the one hand, additional sealing between the movable pane (moving upwards and downwards) and the fixed pane or first pane.On the other hand, this design has the advantage of successfully passing a test known as the "ice scraper test," because this sealing lip has improved mechanical properties and thus prevents damage when scraping ice.

[0010] The sealing lip has a stop in the transition zone to the sealing element disposed in the U-shaped guide, which reduces the spreading or lifting of the sealing lip relative to the up-and-down moving disc when an ice scraper is inserted.

[0011] According to a first embodiment of the invention, the guiding element is provided to comprise a U-shaped guide which has a guiding portion an inner and an outer guide section separated from each other by a guide base. This creates the receiving space for the sealing element and the disc that moves up and down within it.

[0012] During the design of the guide element, it may be provided that the inner and outer guide ribs do not extend beyond the longitudinal side of the first washer in the direction of the movable washer, both upwards and downwards. Alternatively, it may be provided that the inner guide rib of the guide element does not extend beyond the longitudinal side of the first washer in the direction of the movable washer, both upwards and downwards, and that the outer guide rib extends beyond the longitudinal side of the first washer in the direction of the movable washer, both upwards and downwards. The latter variant has the advantage of allowing the transmission of increased support forces to the movable disc, both upwards and downwards, via the guide element.

[0013] Preferably, the U-shaped guide of the guide element consists of a rigid component that is at least partially encased on one outer side by a flexible component. This rigid component can, for example, be designed as an insert piece. When the flexible component is introduced into an injection mold into which the first disc and the rigid component are inserted, the rigid component is at least partially encased, and a bond is formed between the first disc and the rigid component. Preferably, the flexible component extends at least partially between the inner face of the first disc and the adjacent inner guide portion of the guide. This results in a rigid bond between the guide element and the first disc. The rigid component can be made, for example, of polypropylene or a similar material, while the flexible component can be made, for example, of TPE (thermoplastic elastomer) or a similar material.

[0014] According to another embodiment, the guide element may consist of a rigid component that is attached to the inner surface of the first window by means of an adhesive strip or an MS polymer layer or an overmolding and which preferably covers the outer surface of the guide element, is covered with a film, painted, surface-treated, or fitted with a cover or a flexible component. This allows the optical effect of the guide element to be easily modified in multiple ways in order to improve visibility for the vehicle occupants.

[0015] Furthermore, it may be advantageous to provide that a support portion extends in line with the inner guide portion of the U-shaped guide, which support portion is formed from the rigid component and is oriented towards the inner face of the glass. The rigid component can thus be L-shaped. This increases the contact area of ​​the guide element with the inner face of the glass. Moreover, when a force is exerted on the outer guide element, this allows for better distribution and support of the force exerted via the support part.

[0016] According to another embodiment of the invention, the guide element has an outer rib-shaped guide portion that is aligned by a guide base at a distance from a surface portion of the inner face of the first pane of glass, the U-shaped guide being formed by a surface portion on the inner face of the first pane of glass and the outer rib-shaped guide portion. This embodiment allows for a reduction in weight.

[0017] This design has the advantage of reducing the depth difference between the outer face of the first window and the upward- and downward-moving window by eliminating the internal guide rib. This reduces the difference in depth between the outer face of the first window and the outer face of the upward- and downward-moving window. Furthermore, the design of such a guide element reduces the weight.

[0018] In this embodiment of the guide element, the outer guide portion or outer guide rib may only extend to the longitudinal side of the first glass in the direction of the movable glass, both upwards and downwards. This outer guide rib may also extend beyond this longitudinal side of the first disc in the direction of the movable glass, both upwards and downwards.

[0019] It is advantageous to provide that the outer rib-shaped guide portion extends parallel to the inner face of the first pane of glass as far as the longitudinal edge of the first pane. It is also possible to provide that a free end of the outer guide rib is inclined towards the inner face of the first pane of glass. This creates a trapezoidal inner space within the guide area between the inner face of the glass and the guide element. This has the advantage of improving the seal's retention through positive engagement. It is not necessary to provide additional retaining elements on the seal to ensure secure positioning within the guide area.

[0020] In this embodiment of the guide element, it is further preferably provided that the rib-shaped guide portion extends into a guide base, thereby aligning the guide portion at a distance from the inner face of the first pane of glass, and that a support portion, bearing against the inner face of the first pane of glass, is formed opposite the outer guide portion. In this embodiment, a rigid component, formed approximately in the shape of a Z, an S, or steps, is provided in particular to form the outer guide portion, the guide base, and the support portion. This, in turn, improves the absorption of a force acting on the movable pane of glass in the upward and downward directions.

[0021] Preferably, in this embodiment of the guide element, at least the outer guide portion and the guide base are formed from a rigid component that is at least partially coated on its outer face by a flexible component, the flexible component preferably fixing the rigid component to the inner face of the first pane of glass. Alternatively, the guide element may be formed from a rigid component and fixed to the inner face of the pane of glass using an adhesive, such as a PU adhesive or similar, or an adhesive strip or an MS polymer layer.

[0022] Furthermore, in this embodiment of the guide element, the rib-shaped guide portion and the guide base may also be made of a metallic material, a lightweight metallic material, or a fiber-reinforced composite material. These versions may be attached to the inside of the first window using an adhesive, such as a PU adhesive or similar, an adhesive tape, or an MS polymer. Alternatively, these materials may be attached to the inside of the first window using a flexible component. In the aforementioned examples of the guide element embodiment, the surfaces facing inward toward the body may also be fitted with a cover, a decorative strip, a coating, or paint.

[0023] The invention, as well as other advantageous embodiments and improvements thereof, are described and explained in more detail below with reference to the examples shown in the drawings. The features arising from the description and the drawings can be used individually or in combination with each other, according to the invention. They show:

[0035] Figure 1 shows a view of a window unit 11. This figure 1 shows a view of the exterior side of the window unit 11, which is mounted in a body. This window unit 11 comprises a first window 12, which can be fixedly mounted in a door of a motor vehicle. The first window 12 is associated with a longitudinal edge 13 or the vertical front face 13 of a second window 14 that can be raised and lowered. Between the first pane 12 and the second pane 14 is a guide element 15 which extends along the longitudinal side 13 of the first pane 12 and downwards into the door beyond the longitudinal side 13 of the first pane 12. The first pane 12 may include a frame 17 which, according to the embodiment, surrounds the pane 12 except for the longitudinal side 13. One or more fixing elements 18 may be arranged on the frame 17 and / or molded directly onto it.These fixing elements 18 allow the first pane of glass 12 to be fixed to or within the door body.

[0036] The up-and-down movable pane 14 may be, for example, tempered safety glass (ESG), laminated safety glass (VSG), or plastic or plastic composite glass. The first pane 12 may also be, for example, tempered safety glass (ESG), laminated safety glass (VSG), or plastic or plastic composite glass. Furthermore, the first pane 12 may be designed as a painted cover made from various materials, such as glass, metal, plastic, wood, or similar materials. The first pane 12 may be transparent, partially transparent, opaque, or completely opaque. Similarly, this first pane 12 may include functional elements, such as a screen for displaying information, or safety features.

[0037] The window unit 11 shown in [Fig.1] can be mounted on a driver's door and / or a passenger door as well as on a door at the rear of the motor vehicle.

[0038] Figure 2 shows a schematic cross-sectional view along line II of Figure 1. This cross-sectional view shows the connection and positioning of the guide element 15 relative to an inner face 18 of the first pane 12. The guide element 15 is fixed to the inner face 18, specifically exclusively to the inner face 18, of the first pane 12. The front face 13 or the longitudinal side 13 and one of the outer sides 19 of the first pane 12 are completely free. The guide element 15 includes a U-shaped guide 21 in which a sealing element 22 can be inserted. This sealing element 22 serves to seal the disc 14 which can be moved up and down.

[0039] This guide element 15 is preferably designed as a two-component component. It consists of a rigid component 23 which is at least partially surrounded by a flexible component 24. The flexible component 24 may at least surround the outer face of the rigid component 23. Advantageously, the flexible component 24 is formed between the main component 23 and the inner face 18 of the first window 12. The flexible component 24 may be formed from a thermoplastic elastomer. Thus, the guide element 15 can be fixed to the inner face of the guide element 15 using the flexible component 24. For example, it may be possible to insert the rigid component 23 and the glass 12 into an injection molding tool, and then inject the flexible component 24, so as to form the guide element 15 and simultaneously establish the connection with the inner face 18 of the first glass 12. The flexible component 24 can also form the frame 17.

[0040] With regard to the materials used for the hard component and the soft component, reference is made to the entirety of document EP 0 857 116 B1 as an example.

[0041] The fixing of the guide element 15 exclusively on the inner face of the first pane 12 allows the second pane 14, viewed from the outside, to be guided so as to be able to move up and down behind the first pane 12. An overlap zone 26 is thus formed between the first and the second pane 12, 14. In an intermediate space between the overlap zone 26 extends part of a sealing element 22, to which is connected on the outside a sealing lip 27, which is oriented both towards the longitudinal side 13 of the first pane 12 and towards an outer side 28 of the second pane 14. This sealing lip 27 has a stop 29 towards the longitudinal side 13 of the first pane. The sealing lip 27 thus rests on the first pane 12 and rests with at least a slight pre-stress on the outer face 28 of the second pane 14. The operation of the sealing lip 27 is described below with the help of [Fig.5]..

[0042] The guide element 15 has, to form the U-shaped guide 21, an inner guide rib 31 and an outer guide rib 32, which are separated from each other by a guide base 33. In addition, the guide element 15 has a support portion 35 which is preferably located in the plane of the inner guide rib 31 and oriented opposite to the inner guide rib 31. This provides an enlarged contact surface for the connection of the guide element 15 to the inner face 18 of the first window 12. This also reinforces the peripheral area of ​​the first window 12.

[0043] In addition, in order to improve the fixing of the guide element 15 on the inner face 18 of the first window 12, a recess 36 can be provided in the hard component 23 between the inner guide rib 31 and the support part 35, which is filled with the soft component 24.

[0044] Figure 3 shows a schematic cross-sectional view of a variant of Figure 2. The structure of the guide element 15 with the U-shaped guide 21 by the inner guide rib 31, the outer guide rib 32 and the guide base 33 arranged between them corresponds to that of Figure 2. Similarly, a support portion 35 can advantageously be provided, the aforementioned portions forming the hard component 23. The hard component 23 can be overmolded on its outer face with the flexible component 24. Alternatively, a cover, a decorative strip 37, or a coating can also be applied to the hard component 23. For attaching the guide element 15 according to [Fig. 3], unlike [Fig. 2], an adhesive tape 38 is to be used, for example. This adhesive tape 38 extends along the flat portion 34 on the inner face 18 of the first pane of glass 12. The guide element 15 is attached to it by means of the adhesive bond.Instead of adhesive tape 38, it is also possible to use a layer of MS polymer. Similarly, it is possible to use overmolding between the U-shaped guide 21 and the inner face 18 of the first window 12.

[0045] Figure 4 shows a schematic cross-sectional view of another variant of Figures 2 and 3. The structure of the guide element 15 with the U-shaped guide 21 via the inner guide rib 31, the outer guide rib 32, and the guide base 33 arranged between them corresponds to that of Figures 2 and 3. This variant differs from Figures 2 and 3 in that it does not include a support portion 35. The guide element 15 is instead designed solely as a U-shaped guide 21. The flexible component 24 can be designed as an overmolding, whereby the inner guide rib 31 is connected to the inner face 18 of the first pane of glass, and the free outer faces of the guide element 15 are covered by the flexible component 24.Alternatively, this U-shaped guide element 15 can also be fixed to the inner face 18 of the glass 12 using adhesive tape 38 or using the other fixing options according to Figures 2 and 3.

[0046] Figure 5 shows a schematic cross-sectional view along line II of Figure 1, which illustrates an alternative embodiment of the guide element 15 of Figure 2. The structure of the guide element 15 of Figure 4 corresponds in principle to that of Figure 2. The difference, however, lies in the fact that, in the variant of Figure 4, there is no internal guide rib 31. The U-shaped guide 21 of the guide element 15 is thus formed by a modified guide element 15, the guide base of which 33 is formed solely by the external guide rib. 32. This guide element 15 can be L-shaped. The guide element 15 can also be Z-shaped or S-shaped, as illustrated. This guide element 15 forms the U-shaped guide 21 with a flat portion 34 on the inner face 18 of the first pane of glass 12. The outer guide rib 32 is positioned at a distance from the inner face 18 of the first pane of glass 12 by the guide base 33. The depth difference between an outer face 19 of the first pane of glass 12 and the outer face 28 of the pane of glass 14, which can be raised and lowered, is thus reduced. This embodiment is also optimized in terms of weight compared to the embodiment of [Fig. 2]. For the remainder, the explanations relating to Figures 2 and 4 apply.

[0047] Figure 6 shows a schematic cross-sectional view of the embodiment according to Figure 5 during a test known as the "ice scraper test." When removing ice from the second pane 14 using an ice scraper, the ice scraper can slip between the sealing lip 27 and the outer face 28 of the second pane 14. The advantageous design of the sealing lip 27, on the one hand, and the arrangement of a peripheral area of ​​the pane 14 that can be moved up and down in the overlap zone 26 relative to the first pane 12, prevent mechanical damage to the guide element 15. The stop 29 on the sealing lip 27 prevents the ice scraper from widening and becoming lodged between the outer face of the second pane and the sealing element 22.

[0048] Figure 7 shows another cross-sectional view of another variant of Figure 5. This variant also includes a guide element 15, which is formed by the outer guide rib 32, the guide base 33, and preferably by the support portion 35. These components form the rigid component 23. The outer face of the outer guide rib 32, the guide base 33, and the support portion 35 are, for example, completely overmolded with a flexible component 24. In this embodiment, the rigid component 23 is attached to the inner face 18 of the first window 12 using an adhesive strip or an MS polymer. The overmolding or flexible component 24 can be connected to the adhesive layer or to the inner face 18 of the first window 12 to ensure a seal. Otherwise, the explanations relating to Figure 5 apply.

[0049] Figure 8 shows a schematic cross-sectional view of another variant of Figures 5 to 7. The structure of the guide element 15 may include the variants according to Figures 5 to 7. In these embodiments according to Figures 5 to 7, the outer guide rib 32 is provided to extend only as far as the longitudinal side 13 of the first window 12 in the direction of the disk 14 which can be moved up and down. In this embodiment according to Figure 8, the outer guide rib 32 is shown in another embodiment. The outer guide rib 32 extends beyond the longitudinal side 13 of the first window 12 in the direction of the movable window up and down 14. This configuration of the external guide rib 32 can also be provided in embodiments according to figures 2 to 4.

[0050] Figure 8 further illustrates another embodiment of the sealing element 22. In this embodiment, the stop 29 on the sealing lip 27 does not extend only partially across the width of the longitudinal side 13 of the first pane of glass 12. Preferably, this stop 29 extends across the entire width of the longitudinal side 13 of the first pane of glass 12. Thus, the longitudinal side 13 of the first pane of glass can be fully protected by this sealing lip 27, particularly against stone chips. This embodiment also exhibits increased resistance in the ice scraper test. Moreover, the free end of the sealing lip 27 opposite the stop 29 can bear with increased force against the outer face of the pane of glass 14, which can be raised and lowered. This also further reduces water penetration.In addition, this makes the offset between the first pane 12 and the movable pane 14, which moves up and down, more aesthetically pleasing.

[0051] This embodiment variant of the sealing lip 27 on the sealing element 22 can also be provided for all other embodiment variants according to figures 2 to 11.

[0052] Figure 9 shows another variant of Figures 5 to 8. In this variant, the outer guide rib 32 is inclined with its free end towards the inner face 18 of the first pane of glass 12. This configuration of the guide element 15 is particularly suitable when the S-, Z-, or L-shaped guide element 15 is connected to the inner face 18 of the pane of glass 12 by an adhesive bond. In this embodiment, it is preferable for the guide 21 to narrow towards the pane of glass 14, which can be moved up and down. This allows for the creation of a trapezoidal guide 21 or a trapezoidal inner space. This has the advantage that the sealing element 22 inserted into the guide 21 can be held in place by a positive engagement. Additional fastening elements, such as those shown, for example, in embodiments according to Figures 7 and 8 by retaining arms, can be eliminated.

[0053] Figure 10 shows a schematic cross-sectional view of another variant of Figures 5 and 6. In this variant, the guide element 15 has an outer guide rib 32 and a guide base 33. In addition, a support portion 35 is provided, which is triangular or roof-shaped and extends into the guide base 33 or surrounds the guide base 33 and preferably extends to the outer guide element 32. This constitutes an alternative to the L-shaped guide element 15 and can also be used in all the The aforementioned embodiments. The outer guide element 32, the guide base 33, and the support portion 35 are preferably designed as a rigid component 23, preferably comprising recesses 36. A flexible component 24, in particular made of TPE, is provided for connecting the rigid component 23 to the inner face of the glass 12. In this embodiment, the inwardly facing outer face of the guide element 15 is provided, for example, with a decorative strip 37 or a cover. This decorative strip 37 or cover can be attached using adhesive tape 38 or glue. It is also possible to glue, emboss, or staple the decorative strip 37 or the cover. Alternatively, a paint or coating can be provided instead of the decorative strip or cover.

[0054] Figure 11 shows a schematic cross-sectional view of another variant of Figures 5 and 7 to 10. In this variant, the guide element 15 consists of an outer guide rib 32, a guide base 33, and a support portion 35. This may be a stepped structure or a Z-shaped arrangement. In this embodiment, the guide element 15 is provided to be made, for example, of a metal, a lightweight metal, or a fiber-reinforced composite material. To fix the guide element 15, the support portion 35 is attached to the inner face 18 of the first window 12 using adhesive tape 38, adhesive strip, MS polymer, or overmolding. Otherwise, the descriptions relating to the preceding figures apply.
