An activation installation for a motor vehicle door having a distribution installation and a flexible transmission means. The distribution installation has a first input and first and second outputs, and is configured for distributing an activation movement to two functional units. The flexible transmission means is configured for transmitting the activation movement at least in portions from the distribution installation to the first or second functional unit. In the assembled state, on a first portion of an activation movement that acts on the first input of the distribution installation, the first input for transmitting the activation movement in portions to the second functional unit is coupled or is to be coupled to the second output. At the commencement of a second portion of the activation movement, the first input and the second output for interrupting the transmission of the activation movement to the second functional unit are decoupled.
