An adjustment assembly or mechanism that permits adjustment of the height and angle of tilt of a vehicle seat includes front and rear latch gears with multiple cogs corresponding to discrete angular positions of the latch gears and consequently discrete heights of the front and rear of the adjustment assembly. The front latch gears pivot about a fixed pivot axis while the rear latch gears pivot about a sliding pivot axis to accommodate tilt angles for the seat. Torsion springs bias the four latch gears to a maximum rotation or pivot position in which the respective ends of the seat are at their highest vertical position. A spindle engages the cogs of the latch gears to hold the latch gears in a particular discrete angular position. Separate front and rear manual actuation levers at the front of the seat can be lifted to release a respective front and rear spindle from a particular cog and allow the driver to adjust the seat position. The independent front and rear adjustment mechanisms allow the driver to place the seat in a wide range of heights and tilt angles, including forward and rearward tilt angles.
