Bench wont fold up

[Hair]

I've been trying to fold the bench seat foward in my truck, but it won't budge, and I can't find and levers or knobs or nothing to pull on to make it fold foward so I can have access to get behind the seat. Now I'm thinking it does NOT fold foward at. Is that right? Do some bench seats not fold foward or is there some kind of trick to this? I'm fixin to just unbolt the whole seat and take it all out unless I'm missing something here. What makes me think it folds forward is that the previous owner has stuff back in there behind it, but then again...maybe that's why he left it back there lol. 71 GMC
