ABSTRACT:
An adjustment mechanism includes two structural elements movable relative to one another, with a first structural element being formed with at least one row of substantially cycloidal teeth and with a second structural element including a drive element guided transversely to a direction of adjustment and formed with at least two driving pins capable of rolling over the teeth. The second structural element has at least one attack surface bearing upon an outer envelope of the drive element and is defined by a line of action extending through a line which is oriented essentially between axes of two driving pins engaging in tooth spaces between teeth and bearing upon a bottom land. In this manner, the drive element is pressed in each respective locked position with its driving pins into the bottom land by gravitational forces.
