ADJUSTMENT MECHANISM Russian patent published in 2012 - IPC B60N2/225 

FIELD: transport.

SUBSTANCE: invention relates to automotive seat adjustment mechanism. Proposed mechanism 1 has first part 2, part 3 to be rearranged relative to said first part by turning about rotational axis A, eccentric and its drive 30, 32. Said first part 2 is provided with external gear wheel 4 with inner ring gear 12. Said second part 3 is provided with internal gear wheel 7 with outer ring gear 16. Internal gear 7 is fitted into external wheel 4 to make tumbler gear, off-centred relative to rotational axis A. Internal gear 7 makes intake space 25 eccentric relative to rotational axis A. Eccentric is arranged in eccentric intake space 25 to revolve therein. External gear 4 is made up of hollow gear wheel 5 with bottom 9 and outer wall 10 extending axially beyond inner ring gear 12. Proposed mechanism comprises retention element 23 displacing in outer wall 10 axially relative to internal gear 7 and fitted on said wall 10 to rest internal wheel 7 upon bottom 9 of hollow gear 4.

EFFECT: adjustable axial clearance.
