Description

Technical Field

[0001] The present invention relates to a vehicle window sealing strip, in particular to an external vehicle window sealing strip of a vehicle door of a motor vehicle. The present invention further relates to a vehicle door of a motor vehicle and a motor vehicle, the vehicle door and the motor vehicle comprising such a sealing strip. Background Art

[0002] The window sealing strip of a vehicle door is an element present along the edge of the opening in the region of which the window slides when the window is opened to allow access to the door. The interior of the sealing strip is in contact with the window and may comprise, for example, a smooth rubber so that the window can rub against the rubber and can slide without being damaged. The exterior of the sealing strip makes it possible to hide the interior and to establish a connection between the body and the window. The exterior of the sealing strip therefore has an important role in the design of the doors of motor vehicles. The sealing strip also makes it possible to ensure the seal at the interface between the movable window and the door frame.

[0003] Typically, the sealing strip is made of an extrusion. However, this type of sealing strip is restrictive, since it is not possible to provide a sealing strip whose cross section can adapt along the sealing strip.

[0004] Sealing strips produced by double injection are also known. These sealing strips allow the cross section to be adapted along the sealing strip. However, these sealing strips are longer and more difficult to manufacture than conventional sealing strips.

[0005] Finally, patent application US2018 / 162209 is known, which discloses a window sealing strip whose cross section varies in the longitudinal direction. This variation in cross section is obtained by a molding technique. Again, this type of technique is time-consuming and costly to implement. Furthermore, the stiffness of the sealing strip may be insufficient. Summary of the invention

[0006] The object of the present invention is to provide an external window sealing strip for a door of a motor vehicle which remedies the above-mentioned disadvantages and improves the sealing strips known from the prior art. In particular, the present invention enables the production of a sealing strip which is simple and reliable to manufacture and which allows the cross section and shape of the sealing strip to be adapted in its longitudinal direction.

[0007] According to the invention, a sealing strip, in particular an outer movable window sealing strip of a door of a motor vehicle, comprises:

[0008] a first extruded portion configured to be pressed against a movable window of a door of a motor vehicle; and

[0009] - A second part adjacent to the first part and comprising an insert fixed to the first part and comprising an overmoulding at least partially covering said insert.

[0010] The overmoulding may have a cross-section which increases or decreases in the longitudinal direction of the second portion.

[0011] The insert may include a first longitudinal end configured to be secured to or inserted into the first portion and a body extending from the first end.

[0012] The overmoulding may extend the entire length of the body of the insert.

[0013] The second portion may include an exterior trim covering at least a portion of the overmold.

[0014] The sealing strip may include a discontinuity between the first portion and the second portion.

[0015] The first longitudinal end of the insert may be clamped into and / or onto the first extruded portion.

[0016] According to the invention, a door of a motor vehicle comprises at least one movable window and an outer window sealing strip as defined above.

[0017] The first extrusion portion may be arranged at a base of the at least one movable window.

[0018] According to the invention, a vehicle, in particular a motor vehicle, comprises a door as defined above.

[0019] According to the present invention, a method for producing a sealing strip comprises the following steps:

[0020] - providing a first extruded portion;

[0021] - provide inserts;

[0022] - securing the insert to the first portion;

[0023] - performing an overmoulding at least partially covering the insert.

[0035] In the remainder of this specification, "interior" is understood to mean the side closest to the interior of the passenger compartment of the vehicle, on which the sealing strip is designed to be installed. In the same way, "exterior" is understood to mean the side opposite to the interior of the passenger compartment.

[0036] In the remainder of this specification, "lower part" is understood to mean the side closest to a horizontal plane on which the vehicle including the door provided with the sealing strip according to the invention lies. In the same way, "upper part" is understood to mean the side farthest from this horizontal plane, or the highest side.

[0037] Figure 1 Schematically shown in FIG. 1 is an example of a vehicle 100 having an embodiment of a vehicle door 1 and / or a sealing strip 10. The vehicle 100 may be a motor vehicle, such as a car or a truck.

[0038] See below Figures 1 to 9Exemplary embodiments of a weather strip 10 and a vehicle door 1 provided with the weather strip according to the present invention are described.

[0039] According to an embodiment of the present invention, a door 1 of a motor vehicle is provided with a sealing strip 10. The door 1 of the vehicle comprises a movable window 2 and a side window joint 5. Car Windows The joint 5 may be arranged between the movable window and the fixed window 3 or the upper body panel.

[0040] The vehicle door 1 also includes a lower body panel 4 located below the movable window 2 and the fixed window 3 or the upper body panel.

[0041] The sealing strip is arranged on the upper side of the lower body panel 4. The sealing strip 10 comprises a first portion 11. The first portion 11 is configured to be swept against a movable window 2 of a motor vehicle door 1, i.e. the sealing strip comprises a lip 115 designed to be pressed against the movable window 2 and to rub against this window when the movable window 2 is displaced.

[0042] The first part 11 is preferably produced by extrusion.The first part is preferably made of a thermoplastic material.

[0043] The first portion 11 comprises a uniform cross section in its longitudinal direction.

[0044] like Figure 3 and Figure 6 As shown, the first part 11 comprises a lateral element 114 terminated by a lip 115 designed to come into contact with the movable window. The lateral element is arranged on the inside of the first part 11. This lateral element 114 sweeps against the movable window during its movement and advantageously makes it possible to accompany the movement of the window without leaving marks on it or damaging said window. This also makes it possible to ensure the seal at the interface between the movable window 2 and the door frame.

[0045] exist Figure 6 , this lateral element 114 is shown in its free position. When mounted, the lateral element 114 is displaced so as to come into contact with the outer surface of the movable window 2. The lateral element 114 thus exerts a uniform force on the movable window 2 so as to push it back towards the interior of the vehicle, thus ensuring that the movable window 2 remains in a wedged shape during its opening and closing movement.

[0046] The first part 11 also comprises a hook element 112 to hook onto the body of the vehicle door of the vehicle. This hook element can extend parallel to the vehicle window on the inner side of the sealing strip.

[0047] Preferably, this hook element 112 can be fixed by clamping to the vehicle body, in particular to a body panel 4 of the vehicle door 1 which forms the outer part of the panel of the vehicle door.

[0048] The first portion 11 extends over at least a portion of the length of the base of the movable window of the vehicle door.

[0049] The sealing strip 10 further comprises a second portion 12 adjacent to the first portion 11. The second portion 12 comprises an insert 20 and an overmolding 30 at least partially covering the insert. The overmolding may also cover a portion of the first portion 11 in a complementary manner. The overmolding 30 may also have the function of forming a positive connection between the insert 20 and the first portion 11 (i.e., a non-removable connection or a connection that can be removed by changing or sacrificing the sealing strip 10).

[0050] like Figure 2 As shown, the insert 20 comprises a first longitudinal end 21. The first longitudinal end 21 of the insert 20 is designed to be inserted into the hollow portion of the first part 11. Alternatively or additionally, the insert 20 may be designed to receive the first end 21 in the hollow portion of the insert 20.

[0051] exist Figure 6 In one embodiment shown, the first end 21 of the insert 20 and the first part 11 comprise cooperating means, making it possible to fix the first end of the insert to the first part. Preferably, the first part 11 comprises a hole 111, and the first end 21 of the insert 20 comprises at least one protuberance 24 designed to cooperate with said hole 111, so that once the protuberance 24 is inserted into the hole 111, any translational movement between the end 21 of the insert 20 and the first part 11 is blocked. For example, the insert 20 and the first longitudinal end 21 are fixed by clamping.

[0052] The insert 20 also includes a body 22 extending longitudinally from the first longitudinal end 21 of the insert 20 .

[0053] Preferably, the longitudinal direction of the first longitudinal end 21 of the insert and the longitudinal direction of the insert body 22 are not parallel. These two directions have an interruption, an angle α between 0° and 90° and / or greater than 5° or 10°.

[0054] The sealing strip 10 thus has an interruption between the first portion 11 and the second portion 12. This interruption is caused by the angle between the end 21 of the insert 20 and the body 22. This interruption thus makes it possible to have a single sealing strip 10 at the base of two windows 2, 3 of the same door, the bases of which are not parallel.

[0055] "Interruption" is understood to mean that there is an angle between the longitudinal axes of two adjacent parts of the sealing strip.

[0056] The insert 20 is made of a rigid material, such as polypropylene or a rigid plastic material.

[0057] The second part 12 further comprises an overmoulding material. This material is overmoulded onto the insert, preferably after the end 21 of the insert has been introduced into the first part 11 .

[0058] The insert 20 thus advantageously allows a joint to be produced between the first extruded portion 11 and the overmoulding 30. The insert 20 also makes it possible to increase the rigidity of the sealing strip 10 and to reduce the risk of breakage during installation.

[0059] The overmoulding 30 is preferably made of a thermoplastic material or a flexible plastic material.

[0060] The overmoulding 30 preferably extends from the first portion 11 to a second longitudinal end of the second portion 12 .

[0061] The cross section of the overmoulding 30 may have an adaptive section in its longitudinal direction. The cross section may increase or decrease from the connection with the first portion 11 towards the second end of the insert 20 .

[0062] The cross section of the overmoulding 30 in the region joining to the first part 11 is substantially the same as the cross section of the first part 11 .

[0063] In one embodiment, the overmold 30 partially covers the first extruded portion 11 of the sealing strip 10 so as to form a flat surface with the exterior of the first portion 11. The overmold 30 terminates flush with the first portion 11.

[0064] The overmold 12 may also fill the holes 111 of the first extruded portion, such as Figure 6 As a result, the protuberance 24 of the insert 20 is more firmly held in the hole 111, and the connection between the first part 11 and the second part 12 is strengthened.

[0065] The second portion 12 may further include an outer trim 13. The outer trim 13 is fixed to the overmold 30. The outer trim 13 partially covers the overmold 30.

[0066] The decorative element 13 is preferably made of stainless steel.

[0067] In an embodiment not shown, the exterior trim 13 may partially or completely cover the first portion 11 and the second portion 12 .

[0068] like Figure 8 and Fig. 9As shown, the outer trim 13 can be fixed to the overmold 30 by a folded portion that is pushed into the overmold 30. The trim 13 can be directly overmolded with the first portion 11 and the insert 20. Thus, the trim 13 can be fixed to the remaining portion of the sealing strip 10 during the overmolding step. In an alternative embodiment not shown, the outer trim 13 is fixed to the insert 20. 0 The outer trim 13 thus comprises a lateral projection introduced through the hole of the insert 20 .

[0069] The first portion 11 is arranged to be in contact with the movable window. The second portion 12 is arranged between the fixed window 3 or the upper body panel and the lower body panel 4.

[0070] The lower body panel 4 is shown in Figure 5 The lower vehicle body panel 4 includes a first interface 41 and a second interface 42 .

[0071] Each interface comprises a surface extending towards the upper side. The thickness of this interface is the thickness of the metal sheet forming the panel, or substantially the thickness of said metal sheet.

[0072] The first interface 41 is arranged to receive the first portion 11 of the sealing strip 10. The second interface 42 is arranged to receive the insert 20 of the sealing strip 10 or the body 22 of the insert 20.

[0073] The lower body panel 4 comprises a notch 45 between the two interfaces 41, 42. The notch 45 is a free space between the two interfaces which allows the end 21 of the insert 20 to pass.

[0074] The second interface 42 includes at least one elliptical opening 43, 44, preferably two elliptical openings. The second interface 42 may include a first elliptical opening 43 at the longitudinal end of the second interface 42 closest to the notch and a second elliptical opening 44 at the longitudinal end of the second interface 42 farthest from the notch. The elliptical openings include holes or through holes passing through the second interface.

[0075] Will refer to below Figures 6 to 9 The arrangement between the interfaces 41 , 42 of the vehicle door 1 and the sealing strip 10 will be explained in more detail. Figure 6 , Figure 7 , Figure 8 and Fig. 9 They are shown according to Figure 1 Cross-sectional view of a motor vehicle door showing planes A, B, C and D.

[0076] Figure 6A cross-sectional view of the sealing strip 10 is shown in the region of the recess 45 of the lower body panel 4. The lower body panel 4 thus allows the first longitudinal end 21 of the insert 20 to enter the first portion 11.

[0077] Figure 7 A sectional view of a sealing strip 10 on a door of a motor vehicle is shown in the region of a first oval opening 43 of a lower body panel 4 .

[0078] The insert 20 comprises a clamping device 23 designed to cooperate with a first oval opening 43 of the second interface 42 of the lower body panel 4 .

[0079] Figure 8 A sectional view of a sealing strip 10 on a door 1 of a motor vehicle between two oval openings 43 , 44 is shown.

[0080] The insert 20 comprises in this area two arms 221 extending on either side of the second interface 42, thus making it possible to ensure that the sealing strip 10 is fixed to the lower body panel 4 between the two oval openings 43, 44. The insert 20 further comprises a transverse arm 222, making it possible to reinforce the overmoulding 30 in the vicinity of the fixed window 3 or the upper body panel.

[0081] Fig. 9 A sectional view of a sealing strip 10 on a door 1 of a motor vehicle in the region of a second oval opening 44 is shown.

[0082] As in the region of the first oblong opening 43 , the insert 20 comprises clipping means 23 which cooperate with the second oblong opening 44 and ensure the fixing of the second portion 12 to the second interface 42 of the lower body panel 4 .

[0083] In this area, the insert 20 comprises two transverse arms 222 which allow the section of the second portion 12 to be increased without using excessive overmolding and allow the second portion 12 to be reinforced.

[0084] This configuration of the insert 20 advantageously makes it possible to increase the section of the second portion 12 and of the overmoulding without reducing the rigidity of the sealing strip 10 .

[0085] The invention further relates to a motor vehicle, a side door or a trunk door of the motor vehicle comprising such a sealing strip.

[0086] The invention further relates to a method for producing a sealing strip, in particular a sealing strip 10 as described above.

[0087] An embodiment of the production method comprises the step of providing a first extruded portion 11 and the step of providing an insert 20. Preferably, the first extruded portion 11 and / or the insert 20 are as described above.

[0088] The method further comprises the step of fixing the insert 20 to the first part 11. Fixing can be performed by gluing, welding. Preferably, fixing is performed by clamping the insert 20 and the first part 11. The insert 20 and the first part comprise complementary shapes so that one can be inserted into the other to improve fixing.

[0089] The method further comprises an overmoulding step at least partially covering the insert 20. Preferably, the overmoulding 30 covers the entire outer surface of the insert 20. In one embodiment, the overmoulding also at least partially covers the first portion 11.

[0090] In one embodiment, the method further comprises providing an outer trim 13. Preferably, during the overmoulding step, the outer trim 13 is fixed to the remainder of the sealing strip 10. Alternatively, the trim may be fixed to the remainder of the sealing strip 10, in particular to the overmoulding, by clamping.

[0091] The invention also relates to a sealing strip obtained by the production method as described above.
