Sure I will try to post some pictures tomorrow of what I have done along with something to show what I didn't like about the original set up.

Rich

Chris, you asked for pictures and I am over delivering.

Here are some pictures of my seat belt set up.

Here are the belts I used. You can see the sub belt coming through the seat.






Here are shots from various angles of the shoulder harness connections. The connection point was moved up about 8" to be more level with the hole on the seat. I slightly enlarged the existing hole used to connect the roll bar to the frame and then used a longer grade 8 bolt to connect two seatbelt fittings, one on either side of the roll bar.





These show the connection for the sub belt. I drilled a hole in the frame just under the seats and used a grade 8 bolt to secure a seat belt fitting. Then ran the sub belt up through the hole I cut in the seat. The sub belt keeps the lap belt from riding up above the waste. I have actually broken a rib on 4 point belts without a sub belt and it was not even in an impact. The metal adjuster clip rode up on me, pushed against my body and kind of hooked under the rib breaking it from the inside out. No fun.







Here is me working on proper placement of the sub belt. My wife thought this looked funny so she snapped a picture.




Here I connected the stock seat belts to show the difference. The problem with this shoulder belt set up is the belts have to travel up from the connection before going through the seat. This causes all the force to be on the seat which is much weaker than the belt. The force should be on the frame and the belt only. If there is a seat failure the 8 inches of belt that travels up will change to 8 inches of slack allowing the body to move forward without restraint.






These shots show the stock shoulder belt set up and the revised set up together to show the difference.





Here is my son on the buggy with the seat belts in use.




Here is my crew of three new and very happy buggy owners.

nice buggy those belts look sweet

Welcome to Buggynews, very good info on the safety
belts, I think I'll use your idea on my Blade buggy.
