"Since I have new seats the bottom part is somewhat thick. The back part pushes the bottom part down at the back and thus up at the front, so that it flips over the front rail. The front rail happens to be about the same size as electrical tubing here in my house. There are clips to fasten this tubing to the wall and I used those clips to screw on the bottom of the seat. When I now install the seat in the car, it clicks onto the rail and is quite secured, but can still be lifted when needed, nice! Off course now the seat is a little raised in the front, but I like that".
