I am In the process of finishing my turtle deck structure, and I have to mount my shoulder belts to it. I know that I want angle of the belt seen from the side to be flat to 30 degrees up as we go aft from shoulder to roof. But to get that angle with the turtle deck contracting in both width and height and becoming more round, putting the mount straight behind the occupant is, ummm, difficult.

So, how far off center, toward centerline of a side-by-side, is acceptable for restraint?

My thoughts are that with the harness pulling from somewhat inboard, crash decel will tend to pull the occupants towards centerline and away from the windows that are outboard. The two seat center lines are 23“ apart so there is a few inches between shoulders In normal seating. Also, with the adjustments for length of the shoulder belts, the slack on both sides can be kept the same even with the mount off center behind the seat.

I have reviewed the install directions for Crow, Simpson, and Hooker, and can not find any guidance on this subject.
