Description

Side window for a motor vehicle

The invention relates to a side window for a motor vehicle, which is formed from plastic.

Side windows made of plastic have long been used as special windows for motor vehicles. These plastic panes have the advantage over glass panes that they are elastically deformable and are therefore extremely unbreakable under load. Plastic discs are therefore used, among other things. used in police security vehicles because they cannot be broken.

Multi-layer plastic panes are used in particular as armored glazing on armored vehicles.

Due to the significantly low specific weight of plastic compared to glass, plastic panes would have considerable advantages over glass panes for motor vehicles. The light plastic glazing would lead to considerable weight savings on the motor vehicle, as a result of which not only the fuel consumption of the motor vehicle can be reduced, but also the mechanical elements connected to the panes, such as window regulators and the like, could be made simpler and cheaper.

Despite these considerable advantages of plastic panes compared to glass panes, plastic panes have hardly found their way into series-produced vehicles. There are many reasons for this. A main reason for the previously very low acceptance of plastic panes compared to glass panes is that only existing glass panes have been replaced with the previous plastic panes are. With the exception of the multi-layer armored glazing, the function of the previously used plastic panes is impaired due to the lower strength of plastic than glass. With thin-walled plastic glazing, it is often not possible to open and close it at high speed, since the windscreen deforms due to the wind.

The invention is therefore based on the object of providing a side window for a motor vehicle which is formed from plastic and has sufficient strength for driving at higher speeds.

The object is achieved by a side window with the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

The side window according to the invention is provided with a reinforcing means on a rear or upper boundary edge.

The plastic material allows completely new ways of design compared to glass, since plastic profiles can be integrally formed on the pane, which significantly increases the strength of the pane. In addition, plastic panes can be provided with frames in the area of the boundary edges, which act in a corresponding manner as stiffening means. Of course, a combination of a profile and a frame is also possible.

Such a design of a side window represents a completely new design principle for motor vehicles, since so far only plane-parallel glazing with a low curvature has been used. The side windows according to the invention can be designed as lifting disks, wherein the stiffening means can additionally function as a guide means in a vertical guide rail.

According to a preferred embodiment of the invention, the side window is at its lower boundary edge with a receiving device for a lifting device by means of a screw connection, adhesive connection, clamp connection, plug connection, Welded connection, snap-in connection, riveted connection, crimped connection or snap connection.

A plug connection is particularly advantageous since the receptacle and the lower boundary edge of the side window can be designed with corresponding profiles, so that the receptacle is fixed with respect to the side window in the longitudinal direction of the boundary edge, but is fixed transversely to it. In such an embodiment, it is possible that a relative movement between the side window and the receptacle of the lifting device can be carried out during a lifting or lowering process. This enables additional design simplifications on the lifting device. Such a connection mechanism between the receptacle and the side window represents an independent inventive concept.

According to a further preferred exemplary embodiment of the invention, the side window is designed as an opening window which is articulated to the motor vehicle on a vertical boundary edge with a swivel joint, the side window having an engagement element on at least one of the further boundary edges, on which a corresponding input arranged on the motor vehicle handle device for fixing a certain position of the side window can engage.

Such an engagement device ensures the spatial fixation of a side window made of plastic. This ensures that the side window cannot be moved out of its position by the airstream or that it stands out from the edges of the motor vehicle against which it lies, which can happen due to the high elasticity of plastic in a conventional type of fastening of a display window.

It is particularly advantageous if the engagement device is designed such that it can also be used to fix an opening position of the side window. From such a display window, it is known that at high driving speeds in an opening position, air vibrations at the gap between the window and the Vehicle that can deform the window. By fixing the pane in the deployed position by means of the engagement device, oscillation or deformation of the side pane is reliably avoided.

Furthermore, the engagement device and the corresponding recesses in the side window can advantageously be further developed such that the engagement of the engagement device in the recesses moves the side window into its closed position. In such an embodiment, no additional motor-operated adjusting elements are required to open the side window. All that is needed here is one or more spring elements which move the side window in its deployed position when the engagement device is released.

Fig. 1 shows a first embodiment of a side window according to the invention in a perspective view. The side window according to the invention is made of one Plastic, especially polycarbonate. Compared to glass, plastics have a much lower density, so that the side windows formed are much lighter than conventional glass panes. The elastic modulus (modulus of elasticity) of polycarbonate is approx. 2,100 N / mm ² . In contrast, the elastic modulus of glass is 68,000 N / mm ² . This is a major disadvantage of plastic compared to glass, which, among other things, has prevented the use of polycarbonate as the starting material for motor vehicle glazing in large series, since the simple replacement of a glass pane that is movably arranged on the vehicle with a corresponding plastic pane is very disadvantageous.

According to the invention, the side window made of plastic is provided with a reinforcing agent. In the embodiment shown in Fig. 1 a, the reinforcing means is represented by a profile. This side window 1 has a lower boundary edge 2, an upper boundary edge 3, a front boundary edge 4 and a rear boundary edge 5. The front and rear boundary edges 4, 5 are each arranged vertically and provided with a reinforcement profile 6. This reinforcement profile 6 has an approximately elliptical cross section and is integrally formed on the side window 1. In the area of the reinforcement profile 6, the side window is about 2 to 3 times as thick as in the rest of the area. The cross-sectional shape of the reinforcement profile 6 is constant over the entire longitudinal extent of the boundary edges 4, 5.

The side window 1 is supported with its vertical boundary edges 4, 5 in a sealing element 7, which has a base body 8 and two sealing tabs 9, 10 arranged on the base body, the base body 8 and the sealing tabs 9, 10 having a hollow channel 11 which is approximately oval in cross section for receiving limit a reinforcement profile.

Since the reinforcement profile 6 has a constant cross section and the hollow channel 11 is designed accordingly, the side window 1 is slidably mounted in two such sealing elements 7 in the region of the front and rear boundary edges 4, 5. The reinforcement profiles 6 give the pane a sufficiently high strength so that it cannot deflect laterally even under a greater load or jump out of the guide formed by the sealing elements 7.

The reinforcement profiles 6 thus also serve as guides for guiding the vertical movement of the side window 1. The reinforcement profiles 6 are therefore provided on the vertical boundary edges 4, 5. The upper and lower boundary edges 2, 3 have no reinforcement profiles.

FIG. 2a shows a further exemplary embodiment of a side window 1 according to the invention on a motor vehicle 12. The side window 1 is shown in FIG. 2a in an open position in which the upper boundary edge 3 is exposed. 2b shows a sectional illustration of the side window 1 from FIG. 2a in the closed position, the side window 1 abutting a sealing element 13 angled twice. The sealing element 13 is fastened to the motor vehicle 12 with an adhesive 14.

The side window 1 has a reinforcing frame 15 on its upper boundary edge 3. In the present exemplary embodiment, the reinforcement frame 15 is formed from a metal strip 16 which is flanged around the upper boundary edge 3 to form a reinforcement frame 15 which is U-shaped in cross section. The reinforcement frame 15 is seated in a form-fitting manner on the upper boundary edge 3 of the side window 1. FIG. 2c shows a reinforcement frame 15 with two beads 86 running in the longitudinal direction, which are introduced into the side walls of the reinforcement frame. The beads 86 engage positively in corresponding grooves in the side window 1. This reinforcing frame 15 can be mounted on the side window 1 by sliding it in the longitudinal direction of the beads 86 and grooves. If the reinforcement frame 15 is made of an elastic material, it can also be pushed in the transverse direction to the beads 86 and grooves until the beads 86 snap into the grooves. The metal strip 16 consists, for example, of a steel alloy or an aluminum alloy. The reinforcement frame 15 can, for example, also be formed from an extruded aluminum or plastic profile.

A reinforcing frame 15 gives the side window 1 considerable bending rigidity without the thickness of the side window 1 having to be increased significantly in the region of the upper boundary edge 2. This is an optically very appealing solution for the upper boundary edge 3, which is exposed when the side window is opened and is therefore easily recognizable.

The side window according to that in FIGS. 1a to 1c can of course be combined with the side window according to FIGS. 2a and 2b, so that a side window is provided which on the vertical boundary edges 3, 4 that shown in FIGS. 1a to 1c Reinforcement profile 6 and on the upper boundary edge 3 have the reinforcement frame 15 shown in FIGS. 2a and 2b.

In Fig. 3a, a side window 1 is shown, which has both a reinforcing profile 17 and a reinforcing frame 18 on the vertical boundary edges 4, 5 and on the upper boundary edge 3.

The cross section 2 of the reinforcement profile 17 has outwardly projecting lugs 19 and a flat web 20 which is formed on the end face at the boundary edges 3 to 5 and whose width is somewhat less than the thickness D of the side window 1. The reinforcement frame 18 is in turn formed from a metal strip which is positively adapted to the reinforcement profile 17 of the side window 1.

Such a combination of reinforcement profile and reinforcement frame is particularly rigid, the maximum thickness d in the region of the reinforcement frame 18 being only slightly greater than the thickness D of the side window 1.

FIG. 3d shows the side window according to the invention in combination with a sealing element 21. This sealing element 21 is in turn formed from a base body 22 and two sealing tabs 23, 24 which form a hollow channel 25 for form a conclusive recording of the boundary edge 3, 4, 5 of the side window 1. In this sealing element 21, the sealing tab 24 arranged on the vehicle interior is tubular and a space 26 is provided on the side of the sealing tab 24 facing away from the side window 1. Due to the tubular structure of the sealing tab 24, this has sufficient inherent rigidity to ensure a secure sealing of the side window. By providing the free space 26, the sealing tab 24 can pivot toward the vehicle interior, so that the boundary edge 3 of the side window 1 can be moved out of the sealing element 21 and inserted again. In addition, the hollow channel 25 between the boundary edges 4, 5 forms a guide for a vertical movement, which prevents the side window 1 from tipping sideways.

The combination of reinforcement profile 17, reinforcement frame 18 and sealing element 21 shown in FIG. 3d is thus suitable for sealing the upper boundary edge 3, the front boundary edge 4 and the rear boundary edge 5, so that both the reinforcement profile 17 and the reinforcement frame 18 on the boundary edges 3 to 5 can be formed circumferentially on the side window 1 and the sealing element 21 circumferentially on the corresponding vehicle frame.

4a to 4c show further exemplary embodiments of a reinforcement frame 27 according to the invention. Similar to the reinforcement frame shown in FIGS. 2a, 2b, this reinforcement frame has an inverted U-shape with a base wall 28 and two leg walls 29. The base wall 28 lies against the end face of the side window 1 and the leg walls 29 rest against the lateral boundary surfaces of the side window 1. In the area of the end face, the side window 1 has a centrally arranged longitudinal bead. The base wall 28 of the reinforcement frame 27 is provided with a corresponding bead 30 which is positively nestled on the bead of the side window 1. This bead 30 causes an additional stiffening of the reinforcement frame 27.

Another embodiment of a reinforcement frame 31 according to the invention is shown in FIGS. 5a to 5c. This reinforcement frame 31 is essentially Chen similarly to the reinforcement frame 27 with a base wall 32 and two leg walls 33, but this reinforcement frame 31 has a step 34 in the region of the base wall 32 and the end face of the side window 1 is correspondingly form-fitting, so that the stepped reinforcement frame 31 hugs the boundary edge of the side window 1 in a form-fitting manner. This step 34 is designed in such a way that the area of the base wall 32 on the inside of the vehicle is higher than the area on the outside of the vehicle. The step 34 thus creates a continuous edge. A surface of a sealing element 35 provided for such a side window 1 (FIG. 5c) is formed with a corresponding edge, as a result of which the step of the side window 1 jumping out of the sealing element 35 is reliably avoided by the step 34 engaging the edge of the sealing element 35. The sealing element 35 preferably has a metal angle 36 for stiffening.

In a modification of this embodiment, a sealing element 37 is attached directly to the reinforcement frame 31. The sealing element 37 completely comprises the reinforcing frame 31, it being in the end region of the side window 1, i. H. is formed adjacent to the base wall 32 with a hollow channel 38.

6a to 6c show a preferred exemplary embodiment of a side window 1 according to the invention for a motor vehicle. This side window has a reinforcing profile 39 and a reinforcing frame 40 all around on the lower, upper, front and rear boundary edges 2 to 5. The reinforcement profile 39 is an approximately 1 cm wider angled section of the side window, which is angled at an angle of approximately 30 to 60 ° with respect to the plane of the side window 1. This angled section is provided on the outer surface with an elongated, flat trough-like groove 41 (FIG. 6b).

The reinforcement frame 40 in turn has a base wall 42 and two leg walls 43, 44. The base wall 42 is formed with a bead 45 adapted into the groove 41. One of the two leg walls 43 covers the end face of the angled section of the side window 1 and the other side The kel wall lies on a strip-shaped area of the side window 1 which adjoins the angled section.

The thickness d of the reinforcement profile 39 is 7 to 9 mm with a pane thickness D of approx. 3 to 4 mm.

6c shows the side window together with a sealing device consisting of two sealing elements 46, 47. The sealing element 46 has two sealing tabs 48, 49, which are arranged at an angle α to one another in accordance with the angle of the angled section of the side window. The two sealing tabs 48, 49 are integrally connected to an additional retaining tab 50 which is attached to the vehicle by means of an adhesive 51. The further sealing element 47 has a sealing tab 52 which is arranged parallel to the sealing tab 48 and is spaced apart from it by the distance d. A sealing tab 52 is provided with two retaining tabs 53, 54, with which the sealing element 47 can be fastened to the vehicle with a plug connection.

The sealing device is suitable both for sealing the vertical boundary edges 4, 5 and for sealing the upper boundary edge 3. To seal the upper boundary edge 3, the sealing tab 52 also serves as a guide when opening and closing the side window 1, the side window sliding with the end face of the angled section along the sealing tab 52.

7a, 7b show further exemplary embodiments of a side window in the region of a boundary edge with an S-shaped reinforcing profile 55 and reinforcing frame 56. The reinforcing frame 56 has a cross-section of an inverted shape with oblique angles. The recesses formed by the S-shaped bend are bridged by the reinforcement frame 56.

8a and 8b show a further embodiment with an E-shaped design of the reinforcing profile 57. This reinforcing profile 57 also is provided with a reinforcement frame 58 which is designed similarly to the embodiment shown in FIG. 7a.

9a, 9b show an exemplary embodiment with a particularly rigid reinforcement profile 59. This reinforcement profile 59 has a channel-shaped base body 60, the channel-shaped base body 60 being arranged on the side window 1 in the direction of the vehicle interior. The base body 60 has a base wall 61 and two leg walls 62, 63. In one of the two leg walls 62, the remaining area of the side window 1 is fastened by means of an angled tendril 64. On the other leg wall 63, two flat reinforcing webs 65, 66 are formed on the outside.

In the region of the groove of the base body 60, reinforcing ribs 67 arranged in a cross shape are formed. The groove-shaped base body 60 is formed in one piece with the flank 64, the reinforcing webs 65, 66 and the reinforcing ribs 67 together with the remaining area of the side window 1 made of plastic. The reinforcement profile 59 is provided with a reinforcement frame 68 which is integrally formed in the region of the leg wall 63 on the reinforcement webs 66, 67 by means of corresponding bulges and bridges the other recesses in the reinforcement profile 59, so that the reinforcement frame 68 is U-shaped in cross section with its base curled.

10 and 11 show side windows 1, with a reinforcement profile 69 formed in the area of a boundary edge, which is formed from a hollow channel 70 integrated into the window 1. The hollow channel is created using an internal gas injection molding process. According to the embodiment according to FIG. 17, the reinforcement profile 69 can be formed with an additional recess, whereby its rigidity is increased.

The side windows shown in FIGS. 10 and 11 can also be provided with a reinforcing frame, which can also extend over the region of the hollow channel 70. 12a schematically shows a side window 1 which is arranged in a receiving device 71 of a lifting device with its lower boundary edge. The lifting device is schematically indicated only by a lever 72.

The receiving device 71 preferably has a profile in cross section, as shown in one of FIGS. 12b to 12d.

According to FIG. 12b, the lower boundary edge 2 of the side window 1 has an inverted T-shape in cross section, the receiving device 71 having a corresponding profile. The side window 1 can thus in the direction of

Longitudinal extension of the receiving device 71 are inserted into the receiving device 71, wherein a profile transverse to the longitudinal extension of the receiving device 71 between the side window 1 and the receiving device 71 is excluded by the profile shape. This plug connection is suitable for carrying out the lifting process when lifting and lowering the side window 1 in a vehicle without the need for additional connecting means.

Further suitable profiles are shown in FIGS. 12c and 12d. FIG. 12c shows an inverted Y-shaped profile and FIG. 12d shows a teardrop-shaped profile, the lower boundary edge 2 of the side window and the receiving device 71 being designed accordingly.

Alternatively or in combination with such a plug connection, it is also possible to connect the side window 1 to the receiving device 71 by means of a screw connection, adhesive connection, clamp connection, snap connection, rivet connection, crimp connection or snap connection.

13a schematically shows a side window 1 designed as an opening window, which is fastened to the vehicle by means of two hinges 73. An opening mechanism 74 is provided on a curved upper boundary edge 3 extending from the lower boundary edge 2 to the front vertical boundary edge 4, with which the side window 1 can be pivoted a little about the hinges 73. The opening mechanism 74 can either be operated manually and has sensors sensor for detecting the position on or is an electrically operated opening mechanism.

According to the invention, the side window 1 is provided with one or more recesses 75 in the region of the lower boundary edge (FIG. 13b). In the present exemplary embodiment, the recess is designed as a groove 75 which extends over the entire lower boundary edge 2. Two actuators 76 serving as engagement devices are provided on the motor vehicle, each of which has a cylinder 77 and lifting bolts 78. The lifting bolts 78 are each arranged vertically displaceably in the respective cylinders 77. They can be moved upwards into the groove 75 and thus form a projection which engages in the groove 75 and reliably prevents the side window 1 from opening.

In the present exemplary embodiment, two actuators 76 are provided. In principle, it would also be possible to provide only one actuator or several actuators. The actuators 76 are arranged as evenly as possible over the longitudinal extent of the respective boundary edges which they are intended to fix on the motor vehicle.

The actuators 76 are arranged in the vehicle interior of the motor vehicle, and with their lifting bolts 78 they can penetrate a region of a side wall 79 of the motor vehicle that is bent twice in order to engage in the groove 75. This double-angled area of the side wall 79 is provided with a sealing element 80, which seals the side window in its closed position from the vehicle (FIG. 13b). The fixing by means of the actuators 76 prevents the side window 1 from being lifted off the side wall of the motor vehicle while driving. The provision of the groove 75 also makes the lower boundary edge 2 much stronger than the remaining area of the side window 1, so that the lower boundary edge 2 also serves as a reinforcing profile.

13c shows the lower boundary edge 2 of the side window 1 with an alternative embodiment of the groove 75, which has a run-on slope 81 on the inside of the vehicle as the groove boundary wall. This chamfer 81 is from the vehicle interior starting at an angle upwards and facing the outside of the vehicle. The lifting pin 78 is provided with a correspondingly bevelled end face 82. By actuating the actuating element 76, ie by executing an upward movement of the lifting pin 78, it presses with its beveled end face 78 against the run-up slope 81 and exerts a force directed into the vehicle interior on the side window 1. The actuator 76 can thus also function as a closing device which moves the side window into the closed position which lies against the side wall 79 of the motor vehicle. In this configuration of the side window and the actuator, it is expedient that one or more spring elements are applied to the side window in such a way that the side window is pressed outwards by the spring elements. As a result, when the lifting pin 78 is withdrawn from the groove 75, the side window is opened by the spring elements and is closed again by inserting the lifting pin into the groove 75 of the side window.

13d shows a development of this exemplary embodiment, in which the entire lower boundary edge 2 is formed with the groove 75 shown in FIG. 13c.

In this exemplary embodiment, the engagement device has two actuators 76, each with a lifting pin 78. At the ends of the lifting bolts 78 there is an engagement rod 83 which is arranged approximately parallel to the lower boundary edge 2 and which has a bevelled upper longitudinal side edge 84 corresponding to the bevelled end face 82. When the side window 1 is closed, the actuator 76 which is closer to the hinges 73 is first actuated, as a result of which the region of the engagement rod 81 which is arranged adjacent to the hinges 73 is first moved into the groove 75. Thereafter, the actuator 76, which is arranged to extend from the hinges 73, is actuated, so that the entire engagement rod 83 is inserted into the groove 75. Since, when the window 1 is open, the groove 75 is arranged at an acute angle to the engagement rod 83 toward the outside of the vehicle, the engagement rod 83 initially engages in the region of the side window 1, which is shown less strongly, with the rest engaging the rest Area of the engaging rod in the groove 75, the side window gradually into the closed position is moved to the side wall 79 of the vehicle. If the engaging rod were first moved upwards with the end removed from the hinges 73, this could result in the fact that, due to the exposed position of the side window, no engagement between the groove and the engaging rod 83 is possible or jamming occurs, which further actuation is not permitted. If, on the other hand, the intervention is first carried out in the adjacent area of the hinges 73, the side window is gradually pulled up and fixed on the side wall of the vehicle.

13e shows a further modification of a side window 1 according to the invention for an opening window, which two recesses 75a, 75b are arranged side by side in the transverse direction to the longitudinal extent of the lower boundary edge 2. The two recesses allow both fixing the side window in the closed position, in which it rests on the side wall of the vehicle, and fixing the side window in the open position, in which the side window is pivoted a little away from the side wall. In the last position of the side window, the actuator 76 engages in the recess 75a arranged inside the vehicle. When the side window is closed, the actuator 76 engages in the recess 75b arranged on the outside of the vehicle.

A further exemplary embodiment of a side window according to the invention designed as an opening window is shown in FIGS. 14a, 14b. This side window 1 is essentially formed from an approximately flat plastic molded part without additional reinforcing elements on the boundary edges. It is in turn attached to the motor vehicle by means of hinges 73 and provided with an opening mechanism 85. In the region of the lower boundary edge, a web strip 88 is formed on the side wall 79 of the motor vehicle and delimits a U-shaped region for receiving the lower boundary edge 2. On the free end edge of the side wall 79, which runs parallel to the web strip 88, a sealing element 89 is provided such that it overlaps the free end edge. The opening mechanism is designed such that it first executes a lifting movement of the side window 1, so that the lower boundary edge 2 is arranged above the web strip 88 and then pivots the side window outwards. When the side window is closed, the side window is first pivoted towards the vehicle in a corresponding manner and then lowered into the U-shaped recess. As a result, when the side window 1 is in the closed position, the lower boundary edge is fixed by the web strip 88 and cannot escape to the outside.

The exemplary embodiment can be easily accomplished with an opening mechanism and hinges which allow a translational movement in the direction of the hinge axis.

The invention is described in more detail above on the basis of various exemplary embodiments in which the side windows 1 made of polycarbonate are used. It is also possible to use side windows made of other transparent plastics. Reinforcement frames explained above are made of metal, metal alloys or plastic. The reinforcing frame can in particular made of fiber-reinforced plastic material, such as. B. polyamides, PBT or ABS. Such plastic frames are produced, for example, by extrusion or injection molding.

Reinforcement frames made of metal can be produced by pulling, bending or flanging. Reinforcement frames made of plastic can be manufactured by extrusion and injection molding.

The reinforcement frames formed from metal strips can be crimped around the corresponding boundary edges. To achieve higher strengths, it may also be expedient to use extruded aluminum profiles. Since the extruded profiles are particularly advantageous for large series, since they can then be manufactured cheaply. The individual embodiments are designed with reinforcement frames and / or reinforcement profiles. Within the scope of the invention it is of course also possible to provide the above embodiments which do not have a reinforcement frame with one. Likewise, it is also possible to provide the above embodiments that do not have a reinforcement profile with one.
