Today I have seen a parked Peugeot 307 Cabriolet (not for sale in the US) uphostered in leather that included a dashboard covered in what seemed red vinyl from the factory. I guess that the car had not been very well maintained and had spent lots of hours under the sun witbout any protection and the vinyl had shrinked a lot, and the thread was in very bad condition, leaving the airbag seams visible:


I read that when a car has a dashboard upholstered in leather, it could shrink if it was under the sun for a long time, but I did not read that vinyl could also shrink?
About airbags, when I made some leather covers for my car seats, I was scared of covering the seat side airbags using my walking foot industrial sewing machine and I left the lateral of the seat open to allow a proper deployment of the airbags.
I read that there are dedicated sewing machines, like the Durkopp Adler 550-867, that monitor thread tension and stitch length to ensure a correct deployment of airbags, keeping all the information in a database to be used in case of possible litigation in an accident, and I was wondering if a non professional trimmer could safely make a seam in an side airbag or dashboard?
Some time ago, I asked that question to a trimmer when I found their shop in a trip and I purchased some scrim foam and she explained me that they just used a thin, non industrial thread to be sure that it would rip in an accident, allowing the inflation of the airbag. I'm sure that if they had been using this technique for some time, it would work, but if I was the one making the seat covers, I would not be so sure that it would always work in an accident exposing myself to a lawsuit in case of problems... it would not be easy to be a trimmer today with modern cars!!
