Car seat tilting mechanism - has interior toothed parts on seat and back with meshing satellite and planet control wheel

摘要

The seat tilting mechanism has a hinge plate (11) on the back and another (12) on the seat. Each has an interior toothed wheel of the same diameter but different numbers of teeth (19, 22). Satellites (35) mesh by the same tooth in the two wheels. A knob works a control planet wheel (30) to engage the wheels and the planet wheel. There is a support between the control wheel and the satellite with a concave surface for the exterior toothed satellite. There are pref. four such surfaces, equally spaced.
