Two-sided drive, e.g. for use with a stepper switching mechanism for adjustment of a motor vehicle seat positioner, said drive being configured so that mechanism ratchets mesh without play in the drive gear wheel

摘要

Two-sided drive for rotation of a driving gear wheel that is connected to an adjustment device is configured so that: the meshing of the ratchets in the teeth of the gear wheel is assured at all times; pivoting of the drive lever from its mid- or null-point position occurs without play; and so that the meshing of the ratchets is friction and wear free.
