Has anyone successfully disassembled LCI comfort seats (with or without ventilation)?

Very few people have these judging by search results all over the internet. Neither REALOEM has the diagram for these seats.

I'm thinking of very carefully removing the rear cover to clean up the ventilation for possible dust. But without DIY or diagrams, I'm worried that I'm going to break clips and other stuff.

 

Found it in the TIS! Detailed instructions (apparently for comfort seats the mechanism is the same as in 7er E66 regardless of ventilation, LCI, or not LCI):
