Help with part ID

I found this part underneath the back seat in my GN. Does anyone know what it is?

Looks like it may have been one of the sides of a helmet where you raise the visor? Doesn't look like anything from the GN.

Hmm? I wonder what it is and where it came from? I am the original owner and as far as I know the back seat has never been out. I guess it's possible it fell through the space at the rear of the seat but it was under the noise insulation. Maybe it was from assy?
