An anti-backbend chain is in engagement with the engagement means, and a chain depot is arranged in the second structural unit.
Claims23
An actuator, comprising:
- first and second structural units arranged independently of one another;
- an engagement means arranged in the first structural unit;
- a drive motor in driving relationship to the engagement means, said the drive motor being arranged in the first structural unit;
- an anti-backbend chain in engagement with the engagement means;
- and
- a chain depot arranged in the second structural unit,
- wherein the anti-backbend chain is configured for deflection in the chain depot in two chain portions which run parallel to one another.

An actuator, comprising:
- first and second structural units arranged independently of one another;
- an engagement means arranged in the first structural unit;
- a drive motor in driving relationship to the engagement means, said the drive motor being arranged in the first structural unit;
- an anti-backbend chain in engagement with the engagement means;
- and a chain depot arranged in the second structural unit,
- wherein the anti-backbend chain has a longitudinal chain axis, said first structural unit being configured for positioning and/or fastening in relation to the second structural unit such that the longitudinal chain axis of a chain portion of the anti-backbend chain has, in a region of engagement of the engagement means in the anti-backbend chain, a different position and/or orientation than the longitudinal chain axis of a chain portion of the anti-backbend chain in a region of the chain depot.
