Definitions
- This invention relates to an actuation mechanism for actuating at least one Bowden cable.
- actuating mechanisms are preferably used in motor vehicle construction and here, for example, for actuating a lumbar support in a motor vehicle seat.
- An actuation mechanism is required to apply a force to a Bowden cable.
- This can be an electrical actuation mechanism, in which the inner cables of a Bowden cable are tightened or relieved in relation to the sheaths of the Bowden cable by means of an electric motor via a suitable mechanism.
- electrical actuation mechanism in which the inner cables of a Bowden cable are tightened or relieved in relation to the sheaths of the Bowden cable by means of an electric motor via a suitable mechanism.
- manual actuation mechanisms in which the operator operates a lever or turns a rotary knob so that the cables of the Bowden cable are tightened or relieved.
- US Pat. No. 6,334,651 B1 discloses a manually actuable actuating mechanism which has a one-way clutch which locks in one direction.
- the actuation mechanism can be equipped with a lever or a rotary knob, and the one-way clutch ensures that the Tension is maintained on the Bowden cable cable when the lever or knob is released.
- the one-way clutch is realized by a roller clutch.
- US Pat. No. 5,794,479 describes an actuating mechanism for the backrest of a vehicle seat which contains an elastic element which brings the lever back into a rest position after actuation.
- the actuating mechanism of this patent is further equipped with a clutch which engages when the hand lever is actuated and rotates the element which is connected to the cable of the Bowden cable. After actuation, the hand lever is returned to its rest position, the cable of the Bowden cable remains tightened.
- the coil comprises a coil body, which essentially has the shape of a circular ring section.
- the bobbin thus has a particularly simple shape, which allows a particularly small and advantageous design of the actuating mechanism.
- the driver body preferably has a cylindrical lever receptacle on which the coil is rotatably mounted.
- the lever mount enables the structure of the actuation mechanism and fulfills several tasks at the same time.
- the driver body due to its cylindrical shape, it supports the driver body in a housing, on the other hand, it is used to hold a hand lever that can be inserted into the holder and, finally, it serves to rotatably support the coil.
- the lever receptacle of the driver body preferably has a through hole and at least one toothing for receiving the actuating lever from both sides of the through hole.
- the actuating lever can thus be inserted into the lever receptacle from both sides, so that the actuating mechanism can be mounted on the left as well as on the right.
- the torsion spring can preferably be compressed by the driver body in order to change the angular position of the coil. If the driver body is rotated via the actuating lever, the torsion spring is compressed, whereby its blocking effect is released and the coil can be rotated.
- the actuating mechanism preferably also has an inner housing to improve the friction between the housing and the torsion spring, the inner housing is arranged radially between the inner wall of the housing and the torsion spring.
- the inner housing preferably consists of two housing halves in order to facilitate the assembly of the inner housing and to secure the inner housing in a rotationally fixed manner in the housing.
- the actuating mechanism preferably also has a cover which can be connected to the housing by clips. This simplifies the assembly of the actuation mechanism.
- the actuating mechanism preferably furthermore has an adapter for mounting the actuating mechanism on a seat frame of a motor vehicle seat, the adapter being equipped with clips which can grip a mounting rib of the housing in any angular orientation.
- the actuating mechanism can be attached to components of any shape, preferably seat frames, by means of the adapter. Only the adapter has to be adapted to the corresponding component and not the entire actuation mechanism. Furthermore, the operating mechanism is designed by the mounting rib so that it can be mounted in different angular positions. The actuation mechanism can thus be used universally. 4.

- the operating mechanism 1 is equipped with an operating lever 100 which is manually operated by the occupant of the vehicle to adjust the lumbar support.
- the actuating mechanism 1 serves to convert the rotary movements which are applied by the occupant into translatory movements which are passed on to the lumbar support via two Bowden cables 90.
- the actuation mechanism 1 can also be used to actuate other elements such as the heater, the headrest, the mirror or the like.
- FIG. 1 shows the individual components of an actuating mechanism 1.
- the actuating mechanism 1 comprises a housing 10, a torsion spring 20, two halves 51 and 52 of an inner housing 50, a driver body 30, a coil 40 and a cover 60.
- FIG. 1 also shows two Bowden cables 90, for example, which can be actuated with the actuating mechanism 1.
- the inner cables 92 of the Bowden cables 90 can be connected to the coil 40.
- the Bowden cables 90 have connections 93 which can be introduced into corresponding receptacles 41 and 42 of the coil 40.
- the coil 40 has a coil body 43 which essentially has the shape of a circular ring section.
