A shaft coupling, especially for coupling upper and lower shafts (23, 22) of a vehicle steering column, comprises two yokes (1, 2) interconnected through respective cross members (4A, 4B) by a pivotable elbow member (3), having two limbs (3A, 3B) pivoted together. The outer end of each limb (3A, 3B) is coupled to a respective one of the cross members (4A, 4B) and the pivot axes (7A, 7B) of the elbow member (3) and the cross members (4A, 4B) mounted on the elbow member (3) 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 limb contacts the other in order to transmit collapse effort through the coupling. |
