DEVICE TO ADJUST POSITION OF AT LEAST ONE MOVABLE PART OF VEHICLE SEAT Russian patent published in 2005 - IPC

FIELD: transport engineering; backrest-to-cushion base adjusters.

SUBSTANCE: proposed device to adjust position of at least one movable part of vehicle seat contains two connecting parts, one being attached to movable part of seat cushion, means to connect said two parts to provide rotation of at least one part connected with movable part around first axle, and control devices by means of which said part connected with movable part of seat can be set in position for rotation and, alternately, can be fixed in preferable angular position. Control devices are furnished with gear rim made, at least partially, in form of circle in said member, connected with movable part of seat, at least two gear wheels engaging with said gear rim and arranged for planetary motion around first axle of rotation, and system of levers made for displacement of said gear wheels to first position in which gear wheels are in meshing with each other and with gear rim, thus preventing rotation of part connected with movable part of seat and for shifting gear wheels in second position in which said gear wheels are in meshing only with gear rim, thus providing rotation of part connected with movable part of seat. Said system of levers, gear wheels and gear rim holding gear wheels remain relatively adding to provide possibility of shifting gear wheels in meshing with each other when shifting gear wheels from first into second position. Invention makes it possible to adjust position of one movable part of seat, particularly, position of backrest, relative to cushion base.

EFFECT: simple design, small number of parts, possibility of quick assembling, no radial play between components.
