can anyone tell me whether you can attatch racing harnesses to the back of the seat so that you can get people into the back? because i dont like the standard seatbelts

i would say no due to the fact that in an accident the seat would just break off thus taking you with it because of the harness being attached to the seat........ You probably could do it but it never would get paased by the transport dept.

All belts [standard or harness] need to be anchored securly at appropriately rated anchor points on the body. Anything less is suicide.

legally no. Harnesses have a certain angle they must be attached at. they should be as straight back as possible from the rear of the seat so they are already tawt when strapped up, otherwise in a crash and the seat moves forward the harness will move with it. Basically they need the mounting point as far away from the latch as possible. Not sure if that makes sense.

thats right sweep....i was having a look at some of the rules (ADR's i think) for harnesses a while ago and the angle between the spot that the harness goes through/over the seat back to the point that it mounts must not be less than 45 degrees (ie. draw a vertical line from the point that the harness goes through/over the seat back to the floor and measure from there to the point it anchors at)

i had a diagram somewhere...i'll see if i can find it

If you are really going to fit proper harnesses to a Mini the only place to anchor them, IMO is into the (reinforced) rear parcel shelf.
Far less stress on the belt then, and the seat.

Rear seat passengers and race harnesses are incompatible, anyhow.... stick with stock front belts, either static or inertia reel if you're gonna carry them.

hey doc, is there anything wrong with anchoring a four point harnes in the bottom rear bolt holes? i mean they've already got spreader plates fitted and i think they line up better (in a clubby anyway) with the seat (ie. keep the belt straighter)

Never done it- my `70 car doesn't have those so I did it thru the parcel shelf, after reinforcing under it with a hunk of hi tensile plate.
But, I have seen it done on later cars- as long as belt angle is less than 45* should be OK..

According to the bloke that designed the racing harness, the rear straps should be mounted at a 90° angle to the spine. If you mount the belts too low it compresses the spine in an accident, if you mount them too high you can fall out of the belts.

If you mount a belt to the rear parcel shelf make sure the shelf is safe. If it has been butchered by fitting speakers or if the shelf was not welded in properly when the car was made then the belts may pull out of the parcel shelf or the parcel shelf may pull ouy of the car. Minis have had a lot of problems with the belts pulling out over the years.

Yes ideally you need a parcel shelf without speaker holes, double skinned AND some hefty plate metal aswell to support the belts. No use giving yourself a false sense of security with a racing harness if it's going to give up on the first sight of impact. I just wish my racing seat had harness holes in it, so I could actually fit a racing harness.

Anto,

There'a always the `angle grinder' option! Makes nice holes if you're careful..

I was seriously considering taking the seat to an auto trimmer and seeing how hard it is just to add holes Not sure if I really want harnesses though, they are expensive and it is a road car after all. My drivers side belt is broken though (which is a bitch I only bought it a few years ago), so I might compromise and upgrade to inertia reel belts... you know they come in a variety of colours now!

Inertia belts are great on the street, but useless on the track. I used to hang on with one hand around Wakefield Pk, and steer with the other....
I've now got a clip-in 3 point harness just for track days, as well as the reels.
