Patent attributes
An adjustable steering column assembly comprises a steering column shroud, a support bracket, and a clamp mechanism. The support bracket comprises two arms having a portion of the column shroud located therebetween. The clamp mechanism comprises a pin that passes through slots in the arms and carries a fixed cam portion and moving cam portion, relative rotation of the fixed cam portion and moving cam portion causing the clamp mechanism to move between a locked position and an unlocked position. The fixed cam portion has an anti-rotation feature that sits at least partially within one of the slots in one of the arms and which co-operates with the side walls of the slot to substantially prevent unwanted rotation of the fixed portion of the cam mechanism. The anti-rotation feature carries at least one contact portion that in use contacts the side walls of the slot as the steering column is adjusted and the contact portion and side walls are configured such that in use the anti-rotation feature does not cause any significant permanent deformation of the side walls due to preferential deformation of the contact portion.
