Not sure if this has happened to anyone else on here, but I could really use some help.

As of late, my passenger seat will not stay locked in it's position. Every time I have a passenger in the car, they will lean back into the seat only to have it fully recline on them.

I'm not exactly sure on what to look for. I've tried messing with it, but it still does the same thing. It only takes a little pressure for it to fall back, and while it's funny to watch, it's also dangerous for that person if we were to wreck.

Anyone?
