The first step is to remove the side plastic lining of the seat cover and remove it so that it does not interfere with the removal of the filler. Then, you can click the threshold on the front of the center frame and then click on the remaining locations. Now you need to click on the bottom of the center frame and then click the top. The bottom and top fillers can now be detach from each other and remove the bottom molding. Next, remove the lower safety-belt anchorage and remove the upper lining.
The upper seat belt in Opel Astra J can also be dealt with in two parts-there is a mechanism for adjusting the height of the safety-belt anchorage.
