What models of seat belt tensioners are there that can be installed on the back of the bucket seat, not on the frame of the profile of your cockpit? I'm using a seat mover and attaching the tensioner to the cockpit could damage the motors. So, I need something that can be installed on the seat and moves with it. I think RCHeliguy has a G-belt installed on the back of his seat and I wonder how complex is that kind of installation and if it's sturdy enough. Aren't there more solutions or ideas for this? I understand it's not easy because of the many models of seats and the rounded shapes of the surfaces.
