Seatbelt question

Hello,

My first post here so I will try to spell correctly even thou I am Swedish

My dog chewed up the seatbelts in our Skoda Oktavia estate, now I wonder if there are any difference between backseat seatbelts between the different Skoda models, like estate has one model and hatchback another?

But there should be difference between left/right/middle models, or?

Regards

Peter
