Urgent: Mazda3 2005 Maxx sport Rear seat issue

Hey There,

I just bought myself a Mazda 3 Maxx Sport 2005 model and noticed
the back seat isnt stuck down (the part you sit your behind on not the back rest)

Have tried for 5 hours and can start the trip till its fixed as its unsafe for the kids.

Any ideas? does it unclip somehow?

 

Here are some pics to
help, so you know what im dealing with
