Door panel and leather seat damaged by glass splinters

Three years ago, my car got an exfoliation through a grass trimmer. Stones were thrown against my car, so that the paint was damaged and the driver’s side window was broken. Although the side pane was broken into small pieces, these were still hung together in large pieces and then fell onto the door panel and my leather seat. The door panel (shocks in the plastic) and the leather seat cover (several cuts in the upper surface of the seat) were added. he) damaged. Now to the ingenuity problem: The insurance of the affected company could have simply paid.. But it did not. Now the thing is already 3 years in court. And to my disadvantage there are now already 2 expert reports, which literally say: “One glass safety glass decays into small pieces, which have no sharp cutting edges and thus can not have caused any damage to my door panel or on my leather equipment.” I’m sure that in several similar situations the interior fittings of cars were damaged by the splinter pieces of one-panel safety glass. Does anyone happen to have a good tip for me? What can I do now?? If I don’t soon think of something useful, I’ll have to live with the fact that I have “thought out” the damage and stay at the expense. I’m for ever Thank you for your help!!!! LG Jan
