3-point seat belt help

[hunter1]

I need some help with a measurement from the floor up to where the bung is placed for a seat belt upper anchor point on a roll bar. I want to do this before putting the cage in. Can someone take a measurement for me please? Thanks

I don't think there's a standard for this measurement. I could tell you how high I made mine, but it might not be comfortable for your body height. If I was doing this I would stand something like a 2x4 in the place where the roll bar tube will be. Then sit in the seat and hold the shoulder belt pivot up on the board and slide it up and down until the belt is comfortable across your shoulder for you. Then just measure that and transfer it to the roll bar.

It's more about the angle of the upper strap versus your spine. If the strap goes down, it can compress or break the occupant's back in an impact. If it goes up too much, it won't restrain. In your OTHER vehicle, measure the distance from the seat butt to the shoulder belt pivot, and try that height in your Bronco.

Yep, that’s what I’ve decided to do. I’ve got old seats in it now, but new ones in the garage for it. I’ll wait till I can get one of the new ones installed before I take the measurement.

Yeah I hope to never have an accident in my 2001 Suburban where the shoulder belt comes off the top of the seatback. It's definitely below the top of my shoulder.
