Passenger Seat Tilts Back

[Okiedoke]

When I'm in the driver's seat and push against the back of the passenger seat, it doesn't move (good). However, if I sit in the passenger seat and lean back, the seat tilts back freely (bad). I had brought it in to the shop to be fixed. They had supposedly fixed it, but guess what is the first thing my passenger noticed as soon as he sat down for the autocross run a week later? Any idea what the problem might be and how it could be fixed? They had mentioned that some hydraulic piston to the left rear below the seat cushion was leaking.

Thanks,
Harry

That bottom seat cushion comes out really easily, if you look close you'll see. From memory you push the front down to undo the clip and lift the cushion off. From there you can probably see what the issue is. Some parts are available at the routine places. I don't remember any hydraulic cylinders being in there? There are bladders for air.
