Tilting Helm Seat - adaptor plate?

[Tim Good]

Has anyone seen or made a plate that can be fitted to the bottom of a seat that allows it to tilt to the angle of heel for longer passages in my pilot house?

I was thinking that a aluminium plate with a curved slot and then an adjustable bolt to fix it in place might work like this:

But then there must be something on the market already surely like this tilting monitor bracket but more sturdy.

Surely someone has seen something like is? I find it hard to believe that someone hasn't made something similar for long passages on one tack for boats with an internal helm position.
