1. A steering apparatus, comprising:

  • a first portion adapted to be fixed to a vehicle body and having a main housing provided thereon;

    a second portion telescopically movable with respect to said main housing, said second portion having first and second ends thereof;

    a third portion including a pivot assembly pivotally connecting said third portion with respect to said second portion and adapted to receive a steering wheel thereon;

    a pivot actuator operatively connected to said pivot assembly for pivoting said third portion with respect to said second portion;

    a telescope actuator operatively connected between said first and second portions for telescoping said second portion with respect to said first portion;

    a first motor stationary with respect to said first portion for driving said telescope actuator;

    a first driver driven by said first motor;

    a first torsionally rigid axially flexible cable having a first end rotatably driven by said first driver and relatively shiftable axially with respect to said first driver and a second end connected to said telescope actuator, such that rotation of said first end of said first cable by said first driver is translated by said first cable to drive said telescope actuator and said first cable is axially flexible as said second portion moves with respect to said first portion;

    a second motor stationary with respect to said first portion for driving said pivot actuator;

    a second driver driven by said second motor; and

    a second torsionally rigid axially flexible cable having a first end rotatably driven by said second driver and relatively shiftable axially with respect to said second driver and a second end connected to said pivot actuator, such that rotation of said first end of said second cable by said second driver is translated by said second cable to drive said pivot actuator and said second cable is axially flexible as said second portion moves with respect to said first portion.
