Centre front seat belt

Good evening all, has anyone managed to install a 3 point seat belt to a front defender centre seat.
I have a belt but can’t think of how or where to mount the top bracket to get it above shoulder height, i thought about a seat belt bar like are installed to wrag tops.

I thought I’d had a brainwave with a harness but apparently there not safe but that’s a different story

Any help please

Why? Just use it as fitted. Older Land Rovers don’t even have seat belts.

However, can see no reason why a harness wouldn’t be safe. And there must be loads of ways to fit a 3 point. But remember the belt should pull you back into the seat not down towards the seat base. Pulling down could cause a broken collarbone.
