Seat Securing at the top. How do you stop them moving sideways
cosmick - 17/8/10 at 09:37 PM

I have a Megabusa with the Westfield Sports padded seats and I want to secure them at the top to stop them moving sideways when cornering hard.

Do any of you have an innovative way of securing them whilst still being able to move them forwards and backwards on their runners?

Any suggestions or pics would be welcome.

Is there anywhere you can drill through and put a bolt through either side?

what about some of those brackets normally used to bolt the seat to the floor, but bolt them through at the top and then to the rear bulkhead?

I had this problem with my Indy. Under hard cornering, the top of the seat flexs which is a bit annoying. The only sensible solution I have seen is to make up a tubular A frame that curls under the seats and attaches to the runners where the seat does and to the top of the seat. All the other options I saw would stop you moving the seat.

Are they fibreglass? You could always lay up an extra layer of glass on the back of the seat - that might do the trick.

They are the padded race type seat, which are fibreglass but padded so you do not see any of the fibreglass material.
I have an idea to make a tube attachment which bolts to the back of the seat. This will fit inside another tube which bolts to the bulkhead behind the seat around the top by the seat belt anchorage. the 2 tubes will fit one inside the other and slide horizontally with the seat runners. This should offer sideways stiffness whilst still allowing the seats to slide backwards and forwards.

Well I don't think a single tube will do much good. Triangulation, like in the chassis is your friend.

It wouldn't exactly be a single tube. one tube would be mounted permanently to the bulkhead, the other would be mounted to the top of the seat. the seat tube would be welded to a square plate mounted to the seat by 4 bolts. the seat tube would move in and out of the fixed tube on the rear bulkhead (trombone style) so would be supported inside. This would stop the seat moving sideways. I appreciate that triangulation would be stronger but I want it to be neat and to be honest, the seats only need to be made more ridgid in a sideways motion. I think this will work.
