Embodiment Construction

[0053] figure 1 The design of the Bowden cable ( 1 ) according to the invention is shown with all essential components. The Bowden cable (1) comprises a sheath (2), preferably made of plastic, and a sliding wire (3), preferably made of steel, arranged inside the sheath (2). At the end of the core wire (3) there is a core wire end stop (7) as well as a connecting element (8). The connecting element ( 8 ) serves as a connector between the Bowden cable ( 1 ) and a functional element, such as an actuating lever for a motor vehicle door latch unit ( 10 ), which is not visible here. The connecting element (8) is a pin (8) shown perpendicular to the Bowden cable (1). The pin (8) is usually welded to the core wire (3) of the Bowden cable. In the present invention, the connecting element (8) can also have different designs, eg loops or hooks. To seal the end of the casing (2), which is not visible here, the casing (2) is surrounded by a shown sleeve (4), which slides over the core ...

Abstract

The invention relates to a Bowden cable used as an actuator of a functional unit in a motor vehicle. The Bowden cable (1) consists of a sheath (2), a core (3) and a seal (4, 5) for the core (3) and is preferably formed as a functional device in a motor vehicle (16) The actuator of (10), the sealing means is formed by a sleeve (4) sliding on the core wire (3) and a spring (5) actuating the sleeve (4). The invention also relates to a latch (10) for a motor vehicle (16) equipped with the Bowden cable (1). The Bowden cables (1) have an efficient seal against environmental influences and also under the usual loads occurring in motor vehicles such as shocks or vibrations.

Description

technical field [0001] The invention relates to a Bowden cable consisting of a sheath, a core and a seal for the core, preferably designed as an actuator (actuator) of a functional unit in a motor vehicle. The invention also relates to a latch unit for a door or a tailgate (back door) as a functional element in a motor vehicle and equipped with the Bowden cable. Background technique [0002] The Bowden cable according to the invention is generally an object consisting of a wire or cable core which is movable relative to a generally flexible design sheath. The sheaths of such Bowden cables are usually made of plastic. The core wires are made of metal or wire, respectively. Bowden cables of the type described above are preferably used as actuators or control elements for various functional elements in motor vehicles. In contrast to the equally commonly used rigid rod elements, Bowden cables are more flexible to use. For example, because of the small radius, they can even b...
