Top having a centering pin for a roof tip

Abstract

A convertible top, having a top linkage, and a roof tip which is fixed to a front cowl of the vehicle in the closed position, and a centering arrangement which defines the position of the roof tip in relation to the cowl in the transverse direction of the vehicle and in the vertical direction of the vehicle in the closed position and which comprises a centering pin which engages into a centering recess of a centering seat. An insert is disposed in the centering recess having a contact side with which a front end of the centering pin is in contact when in the centering position and formed by an elastic element. Alternatively, an elastic element is disposed on the front end of the centering pin, and in contact with a ground of the centering recess when the centering pin is in the centering position.

Description

[0021] In the drawing, embodiments of a top according to the invention are illustrated in a schematically simplified manner and are explained in more detail in the following description.

[0022] FIG. 1 shows a schematic side view of a convertible vehicle having a top according to the invention;

[0023] FIG. 2 shows a perspective view of a centering arrangement of the top;

[0024] FIG. 3 shows a cross-section through the centering arrangement along a longitudinal direction of the top and a transverse direction of the top during entry of a centering pin into a centering recess;

[0025] FIG. 4 shows a cross section of the centering arrangement corresponding to FIG. 3, but with the centering pin and the centering recess in the engaged position;

[0026] FIG. 5 shows a longitudinal cross-section through the centering arrangement along line V-V in FIG. 4;

[0027] FIG. 6 shows a perspective front view of an insert of the centering recess;

[0028] FIG. 7 shows a perspective rear view of the insert;

[0029] FIG. 8 shows a cross-section through the insert along line VIII-VIII in FIG. 6;

[0030] FIG. 9 shows a cross-section through an alternative embodiment of a centering arrangement corresponding to FIG. 3;

[0031] FIG. 10 shows an illustration corresponding to FIG. 9, but with a centering pin and a centering recess in the engaged position;

[0032] FIG. 11 shows a perspective front view of an insert of the centering arrangement according to FIGS. 9 and 10; and

[0033] FIG. 12 shows a perspective rear view of the insert of FIG. 11.

[0034] FIG. 1 shows a cabriolet vehicle 10 having a folding top 12 which can be displaced between a closed position, in which a vehicle interior is covered, and a storage position, in which the vehicle interior is uncovered. In the closed position illustrated in FIG. 1, a front bow, which forms a roof tip 14 of the folding top 12 and can be displaced by means of a top linkage 16, is fixed to a front cowl 18 of the vehicle 10, the front cowl 18 forming an upper frame part of a frame of a windshield 20, said upper frame part extending in the transverse direction of the vehicle.

[0035] The closed position of the folding top 12 is secured by means of a locking device 22 which is disposed on the roof tip 14 and which comprises a locking hook (not illustrated) which is engaged with a locking bolt (not illustrated) disposed on the front cowl 18.

[0036] In order to define the position if the roof tip 14 in relation to the front cowl 18 and to be able to guide it toward the front cowl 18 with accuracy of position in particular during displacement of the folding top 12 from the storage position into the closed position, the locking device 22 comprises a centering arrangement 24, which is illustrated in more detail in FIGS. 2 to 8.

[0037] The centering arrangement 24 comprises a centering seat 26 which is installed on the front cowl 18 and which has, at the side facing in the direction of the rear of the vehicle, a centering recess 28 which has an at least largely rectangular outline and which serves to be engaged by a centering pin 30 which is attached to the roof tip 14 via a brace 32.

[0038] The centering recess 28 of the centering seat 26 is surrounded by adjacent entry slopes 34 which, when the centering pin 30 is guided toward the front cowl 18, direct the centering pin 30 in the direction of the centering recess 28 in such a manner that the centering pin 30 and thus the roof tip 14 have a defined relative position in relation to the front cowl 18 with respect to the transverse direction of the vehicle and to the vertical direction of the vehicle.

[0039] To avoid scratching of the centering seat 26 and other vehicle components during the introduction of the centering pin 30 into the centering recess 28, the centering pin 30 has a plastic overmold 35 on its front end facing the centering recess 28. Otherwise, the centering pin 30 is made of metal and integral to the brace 32. Likewise, the centering seat 26, which is attached to the front cowl 18, is made of metal as well.

[0040] The centering recess 28 has an insert 36 which is made of a soft EPDM plastic material having spring-elastic properties. The insert 36 forms the ground of the centering recess 28 and has a contact side 38 which is provided with a corrugation 40, as can be seen in particular in FIGS. 6 and 8. Moreover, a rib 42 is formed on the contact side 38 of the insert 36, said rib 42 being engaged with a groove-shaped recess 44 of the centering pin 30 when the top is in the closed position so as to form a second centering (cf. FIG. 4). The corrugation 40 formed on the contact side 38 of the insert 36 extends beyond the rib 42 and is oriented in the vertical direction of the vehicle.

[0041] To keep the insert 36 in position within the centering seat 26, a retaining rib 46 is formed on either side of a longitudinal center plane of the insert 36 in the portion of the insert 36 that faces away from the contact side 38, each rib 46 having a substantially hook-shaped cross-section and engaging behind a respective retaining surface 48 of the centering seat 26, the retaining surfaces 48 being formed by cutouts in the centering seat 26.

[0042] To be able to install the insert 36 in the centering seat 26 and to be able to deform it in the area of the retaining rib 36 in order to do so, the insert 36 has a cavity 50 at the side facing away from the contact side 38, the length of said cavity 40 approximately corresponding to the length of the retaining ribs 46. Thus, when inserting the insert 36 into the centering recess 28, the material of the insert 36 can retreat into the cavity 50 in the area of the retaining ribs 46 and can spring back when the end position is reached, causing the retaining ribs to engage behind the retaining surfaces 48.

[0043] In FIGS. 9 to 12, an alternative embodiment of a centering arrangement 24 is illustrated. The centering arrangement 24 largely corresponds to the centering arrangement of FIGS. 2 to 8, but differs therefrom in that the front end of the centering pin 30 is plane, i.e. does not have a groove-shaped recess. Accordingly, in a centering recess 28 of a centering seat 26, the centering arrangement 24 also has an insert 36 that has a plane rib-free contact side 38 with which the centering pin 30, which is provided with an overmold 35, is in contact when in the engaged position.

[0044] Otherwise, the centering arrangement 24 corresponds to the centering arrangement of FIGS. 2 to 8.
