Narrative:
While flying along the san mateo/92 highway towards the 880 north at 2000 feet MSL inside the oak class C airspace near the jackson street waypoint. We were instructed by ATC to remain clear of an MD11 on final into oak. We had more than a mile of separation and turned right to the south east to stay away from the approach path of the MD11. ATC then cleared us to continue pilot navigation once the MD11 was approximately 3 miles farther down the approach. I turned toward a point that I determined would keep us above the MD11's wake turbulence at 2000 feet MSL. We then encountered wake turbulence I would describe like going over a speed bump in a car too fast. I would estimate a momentary negative G of around -0.2. The rest of the flight was a normal flight back to our base airport. The reclining function of the passenger seat was damaged and we think it occurred in the wake turbulence event. No other damage.
