Reclining problem with driver side...Need Help..Plz.

Hello there, this is my first post on the site. I own a 1999 Cavalier Z24. Right now the driver side seat will not recline back to a 90 degree position.
The most it will do stay at a 110 degree position.(at this position the seat is abit reclined...also there is some play ....what I mean is you can move it back further 2 inches just by pressing on the head rest)
I am a tall guy 6 foot 3 so I may have put on more pressure on the seat when reaching for my walet in my backpocket.. I am not sure.

Can anyone help me with the problem..

thx
