RS Adventerous Roadtrek Rear couch seatbelt

[Clineomine]

We just bought a 2015 Roadtrek RS Adventerous and the rear bench seat folds down to make into a bed. It came with seat belts, but they aren't bolted down and I can't find anywhere I can bolt them down in the back. The shoulder belts are installed on the sides, but the clip side of the belts were just sitting in the back "basement" when we purchased it. Can anyone tell me where these are supposed to go? Can't find anything in either the Mercedes or Roadtrek Manuals.
Thanks.

Mine are bolted to the floor under the couch. (See red arrows)

Thank you. Apparently they were never installed because there are no holes in the plastic cover. But I do see an indentation where I may be able to pop out the hole to expose the threads for the bolts below.

Apologies re the dusty condition of the reargate storage area where the noted belts are secured in our 2010/2011 RS Adventurous. You are correct that there are knock out plastic floor panel components which should reveal threaded openings for bolting in the hip level seat belt ends. Just completed our 27th Ontario-Alberta-Ontario migratory trip with this vehicle hence the dust. Detailing will occur soon. Good luck finding the attachment points.
