Seat rail restricted range

[ianwayne]

I've got the seats out for a refurb. at the moment and noticed the different way the seat rail movement is controlled.

On removing them, I noticed that there is a horizontal nut and bolt put through the outer seat rail on the passenger seat. It seems to be there to restrict the rearward movement of the seat, but I don't see why it would be there? The seats can't go far enough backwards to come off the rails anyway it seems to me.




On the driver's side, the range of rearward movement is controlled by a nut and bolt put through the seat base! The seast rail buts up against it on rear movement. Please forgive the blurry image:



The one on the driver's seat base seems typical TVR to me, an afterthought. The one on the passenger side is obviously in the design, but are either of them really necessary? If they were removed, would there be more legroom or would the seats become unstable?

The seat adjusters are identical on both seats by the way. Only the raiser blocks on the driver's seat distinguish the rails from each other, apart from that horizontal nut and bolt!

The first thing to check is that there are sufficient slots for the adjustment device to engage with further back if you did gain extra travel...

Yes, there's plenty of spare movement there.

But to be on the safe side, I've left the bolt fitted. I was just curious as to why it was there in the first place!

I think it’s to keep the runners lined up or something like that, stops the free side getting out of position or that’s what I concluded a few years ago when I found that bolt in mine.
I too left it there
