1. Electrically adjustable steering column, comprising:
- a motor;
an outer drive shaft connected to the motor; and
an inner drive shaft longitudinally mounted through the outer drive shaft and connected to the motor, wherein the motor provides a rotational movement of the outer drive shaft to control the vertical movement of the adjustable steering column and a rotational movement of the inner drive shaft to control the longitudinal movement of the adjustable steering column.
