Abstract
A vehicle steering column (10) comprises a one-piece steering column member (12) that includes a plurality of elongate wall portions (20-24) that extend generally parallel to a longitudinal axis (28) of the steering column. The plurality of wall portions (20-24) at least partially define a chamber (26) in the member (12) for receiving an axially extending steering shaft (30) of the vehicle. The member (12) has a generally rectangular exterior configuration. The member (12) includes a vehicle mounting portion (90, 92) formed as one piece with the elongate wall portions (20-24). The vehicle mounting portion (90, 92) extends from the wall portions (20-24) and is adapted for fastening the steering column member (10) to the vehicle body.
