<p>A shaft coupling, especially for coupling upper and lower shafts of a vehicle steering column, comprises two yokes interconnected through respective cross members by a pivotable elbow member having two limbs pivoted together. The outer end of each limb is coupled to a respective one of the cross members and the pivot axes of the elbow member and the cross members mounted on the elbow member are parallel to one another. The coupling is suitable for a steering column which is rake and/or reach adjustable and allows, upon impact in a crash situation collapse of the coupling so one limbs contacts the other in order to transmit collapse effort the through the coupling.</p> |
