Hi,

I've made an expanding foam seat insert as photo below.

I've sat in it and stuck in a biro where the crown jewels finish



My question is how do people fix the crotch straps to the chassis in this situation? My concern is that normal eye bolt fixings will be too high and stick through the seat. Any ideas please?

thanks, Keith

Hi

The eye bolts do not go directly below. They are positioned back by your hips or slightly in front of your lap belt anchors. The crutch strap then runs forward under the seat and through the tie down mounting as described in the other thread.
If you like i can get a pic of the setup. ?

Cheers Matt

Yes please matt. I'm also interested in this

I have seen pictures where the anti-sub straps attach where you describe, but that won't work with an expanding foam seat "insert" as it doesn't have the structural integrity to loop under, through, and up between my legs also because of my height, the seat is quite thin where you describe and the eye-bolts would probably come through the seat there too! I believe the blue book requires that the straps attach either in line with the notional chest -- crotch line downwards or up to 20 degrees back from this point.

Have you seen your suggested method used with this type of seat i.e. treating the chassis as the seat and the expanded foam as a 'seat insert'?

I think I will perhaps need to attach my straps using the "sandwich of metal plates" directly to the floor, wrapping the straps in the proscribed manner, but was hoping that someone had done this already and could suggest the best and hopefully simplest approach.


Thank you for your reply, cheers, Keith

Hi

On my seven there is a tranverse 1" box section under the seat and the eye bolt is secured through the side of this. I secured my 5 point to this no problem.
