Claim 5:
6. A vehicle steering column assembly comprising:
a first steering column component;
a second steering column component; and
a torsion bar disposed between the first steering column component and the second steering column component, the torsion bar being a single, integrally formed component comprising:
a first end operatively coupled to the first steering column component;
a second end spaced from the first end and operatively coupled to the second steering column component;
an active section positioned between and integral with the first and second ends, the active section having a length defined along the axis which the torsion bar extends along;
a chamfer extending immediately and radially inwardly from the active section to one of the first end and the second end;
a cross-section transverse to the axis, the cross-section defining a contour of the torsion bar where the contour is uniform along the entire length of the active section; and
wherein the contour is defined as of at least one of a polygon and a polygon-like shape.
