Harness bar with no cage??

Just to clarify, that's assuming no hoop is installed.

Harness bars are used for low speed events only where rollovers aren't an issue.

Correct.

Inward as in toward the centerline of th vehicle. Forward not as that are what the tensioners and ratchets are for.

Trust me, if the tensioners & ratchets are locked down, your movement toward the vehicle centerline is going to be minimal at best. Definitely not enough to protect you from damage to the outboard side of your body/head should that side of the vehicle intrude.

after installing a few harness bars in corvettes, and building one for a dakota, personally i like them for track days. they provide a good middle of the road solution to proper geometry on five point harnesses. what really worries me is the guys that run the huge belts to teh back seat floorpan. thats just scary looking to me, and i see a lot of guys in DE1 and DE2 running them.
as far as the roof crushing/3 point thing, i dont know as none of my customers have rolled their cars with a harness bar. i do know that the properly functioning 3 points in the subaru i rolled helped to hold me upright throughout the trip.

as for fabricating one in a classic musclecar, i have looked at this for a 66 mustang, a 70 duster, and a 73 camaro. all the cars are similar as they have no real solid b-pillar to mount to, and the factory 3 point location (for two of them) is in the roof structure. the solution i devised, but have not implemented yet, is to use a tube running from theupper seatbelt mount to a plated section of floor, with a stub sticking out much the same way as a stub for a swing out door bar. do this on both sides, and use a triangulation brace top the rear of the car. bolt the harness bar to the stubs coming off the side tubes, and rock.

on a side note, on the vettes we use the factory lap belt mounting locations for the lap belts, and the two bolts for the pivots on the three point seatbelts to bolt the bar in. then most of them use a rod running to a seatbelt bolt to keep ot from rotating.


hope this helps, and i can maybe add more when im not sick.

Jake How much does that cage set one back?
