Adjustable steering apparatus for a car featuring a one piece column with an enlarged portion

摘要

An adjustable steering system for a car comprises a steering column 1 supported by a clamp assembly 4. The column features an expanded portion 2 which is formed as part of the main column 1. Each side of this expanded portion has an elongate hole 3, which is orientated axially with respect to the column, and allows the fastening bolt 6 of the clamping mechanism to pass through it. This arrangement allows telescopic adjustment of the column. Additionally, the clamping mechanism may have a hole running perpendicular to the elongate holes in the column, allowing for additional tilting or angular adjustment fo the column. The column should preferably be formed by hydroforming.
