Problems solved by technology

[0003] The known plastic drive cables have the following problems: satisfactory noise characteristics cannot be obtained in operation due to the rattling noise caused by the sliding of the teeth on the guide surfaces; Require
However, in the case of such a drive cable, it may occur that the cable jumps in the area of ​​the drive pinion, which in turn is connected to undesirable noise characteristics and high wear

Embodiment Construction

[0051] exist figure 1 A roof 10 is shown in FIG. 2 , which is attached to a passenger vehicle, not shown, and includes a roof opening 12 which can be selectively closed or at least partially opened by means of a cover element 14 . The cover member 14 thus constitutes a vehicle component that is movable relative to the vehicle structure.

[0052] In order to be able to move the cover member 14, it is connected with a displacement kinematics mechanism comprising, on each of its two sides, a drive slide 16A or 16B with respect to the vertical longitudinal center plane of the roof, which drives The slider 16A or 16B is guided in a corresponding guide rail 18A or 18B extending in the longitudinal direction of the roof.

[0053] Compressively rigid drive cables 20A or 20B are connected to drive sliders 16A and 16B, respectively. The drive cables 20A and 20B are guided via corresponding guide lines to a common drive motor 22 and mesh with a common drive gear 24 of said drive motor....

Abstract

The invention relates to a drive cable for actuating a vehicle member being movable as against a vehicle structure, comprising a cable body (26) which is made of plastics, and which includes an denticulation (28) extending in the axial direction for engaging with a driving toothed wheel (24) and through which an armouring extending in the axial direction reaches. The denticulation (28) is formed by pocket-like recesses (34) which are spaced apart in the axial direction at regular intervals, and which are limited, in the longitudinal direction of the cable, by flanks of resulting tips of teeth(36) formed by the cable body (26) and in the transverse direction of the cable, on each of their two sides, by a pocket flank (38) and which are in each instance limited by a root of a tooth (40) onthe bottom side, the armouring reaching through said cable body (26) beneath said recesses (34) and said tips of teeth (36), the armouring defining an armouring plane (A) which extends in the transverse direction of the cable and in the longitudinal direction of the cable, and in which at least two continuous armouring harnesses (30A, 30B, 30C) extending in the axial direction are arranged side byside and / or in which at least one armouring harness (30) having a flat cross-section is arranged.

Description

technical field [0001] The invention relates to a drive cable for actuating a vehicle component movable relative to a vehicle structure and a drive unit comprising a drive gear and at least one drive cable of this type. Background technique [0002] Drive cables for actuating vehicle components that are movable relative to the vehicle structure are known from practice and are used for actuating, for example, cover components of retractable roof arrangements, by means of which the roof opening of the relevant vehicle can be Selectively closed or at least partially open. The drive cable transmits drive from the drive motor to the movable vehicle member and may be formed from a flexible plastic body connected to the vehicle member and including teeth that engage the drive motor or a drive gear of the transmission. In order to provide the plastic drive cable with the required stability, reinforcements can extend in the axial direction through the cable body on which the teeth a...
