Backseat rattle

Do your 991 rattle?

My 991.1 2013 Carrera 4 with 39 000 km has started to rattle when going over uneven surfaces. There roads are terrible where I live so I kind of hear it all the time. I believe that the sound originates from the backseats and is not related to the seatbelts. But I'm unable to pinpoint it any further.

Has anyone had this problem before?
Any tips on how to go about fixing it?

Do you have a glass sunroof? That's what caused mine and is a known fault at Porsche (which they fix by lubricating the rubber seals).

No sunroof on the car. I believe that the rattle is originating from the backseat rest or the plastic handle that is used for tilting the backseat rest.
But it is really hard to pinpoint as it only occurs during driving.
