Abstract

An arrangement for isolating vibration of Bowden cable-actuated components includes a Bowden cable, an actuation element coupled at one end to the Bowden cable and including a mounting eye, a damping element arranged in a positive-fit connection in the mounting eye, and a transmitter element supported within the damping element for actuating the Bowden cable such that it can be deflected. The damping element includes an elastic grommet having a defined recess lying in a specified deflection direction of the transmitter element. In a non-actuated state, the transmitter element is disposed at a centered position within the elastic grommet and is movable into contact with the mounting eye due to the effect of a deflecting actuation force under compression of the elastic grommet in an area of the recess.

First claim

The invention claimed is:

1. An arrangement for isolating vibration of Bowden cable-actuated components, comprising:
a Bowden cable;
an actuation element having a first end coupled to the Bowden cable and a second end comprising a mounting eye;
a damping element arranged in a positive-fit connection in the mounting eye; and
a pin sized and shaped to be supported within the damping element;
wherein, the damping element comprises an elastic grommet having a defined recess lying in a specified deflection direction of the pin;
wherein, in a non-actuated state, the pin is disposed at a centered position within the elastic grommet,
wherein, in an actuated state, the pin is in contact with the mounting eye due to the effect of a deflecting actuation force applied to the pin to cause compression of the elastic grommet in an area of the defined recess,
wherein, the arrangement further comprises a collar surrounding each side of the mounting eye and at least one projection positioned on a side of the mounting eye, and
wherein, the at least one projection engages in an associated recess in the collar of the elastic grommet.

2. The arrangement of claim 1 , wherein the collar is disposed on the elastic grommet.

3. The arrangement of claim 1 , wherein:
the elastic grommet comprises an outer contour,
the mounting eye comprises an asymmetric inner contour, and
the outer contour of the elastic grommet corresponds to the asymmetric inner contour of the mounting eye.

4. The arrangement of claim 1 , wherein the elastic grommet comprises a rubber mixture with a hardness in the range from 20 to 90 Shore A.

5. The arrangement of claim 1 , wherein the actuation element comprises a flattened head portion and a fastening portion, the mounting eye being formed in the flattened head portion and the Bowden cable being coupled to the fastening portion.

6. The arrangement of claim 1 , further comprising a sheathing partially disposed around the Bowden cable for protection.

7. The arrangement of claim 1 , wherein the actuation element is spaced from the pin in the non-actuated state to isolate vibrations from the Bowden cable to the pin.

8. A system for isolating vibration within a plurality of Bowden cable-actuated components, comprising:
a Bowden cable;
an actuation element having a first end coupled to the Bowden cable and a second end comprising a mounting eye;
a damping element arranged in a positive-fit connection in the mounting eye; and
a pin sized and shaped to be supported within the damping element;
wherein, the damping element comprises an elastic grommet having a defined recess adjacent the pin;
wherein, in a non-actuated state, the pin is disposed at a centered position within the elastic grommet,
wherein, in an actuated state, the pin is in contact with the mounting eye due to the effect of a deflecting actuation force applied to the pin to cause compression of the elastic grommet in an area of the defined recess,
wherein, the arrangement further comprises a collar surrounding each side of the mounting eye and at least one projection positioned on a side of the mounting eye, and
wherein, the at least one projection engages in an associated recess in the collar of the elastic grommet.

9. The system of claim 8 , wherein the collar is disposed on the elastic grommet.

10. The system of claim 8 , wherein:
the elastic grommet comprises an outer contour,
the mounting eye comprises an asymmetric inner contour, and
the outer contour of the elastic grommet corresponds to the asymmetric inner contour of the mounting eye.

11. A system for isolating vibration within a plurality of Bowden cable-actuated components, comprising:
a Bowden cable;
an actuation element having a first end coupled to the Bowden cable and a second end comprising a mounting eye;
a damping element arranged in a positive-fit connection in the mounting eye; and
a pin supported within the damping element;
wherein, the damping element comprises an elastic grommet having a defined recess lying in a specified deflection direction of the pin;
wherein, in a non-actuated state of the pin, the pin is disposed at a centered position within the elastic grommet,
wherein, in an actuated state of the pin, the pin is in contact with the mounting eye due to the effect of a deflecting actuation force applied to the pin to cause compression of the elastic grommet in an area of the defined recess,
wherein, the arrangement further comprises a collar surrounding each side of the mounting eye and at least one projection positioned on a side of the mounting eye; and
wherein, the at least one projection engages in an associated recess in the collar of the elastic grommet.
