Patent number: 9452772Abstract: A steering column assembly shroud includes a first member having an end portion which is received within a second member having at least one slit through its wall extending partially along its length. A guide bush is located between the first member and the second member and fixed relative to one of the members. The guide bush provides a surface over which the other member can slide to alter the overall length of the shroud. A clamp mechanism squeezes the second member onto the guide bush which is, in turn, squeezed onto the first member. The cross section of the guide bush varies along its length to vary the resistance it provides to crushing by the action of the clamp mechanism when the shroud is at its greatest length and the resistance it provides when the shroud is clamped at its shortest length.Type: GrantFiled: September 4, 2009Date of Patent: September 27, 2016Assignee: TRW AUTOMOTIVE US LLCInventor: Thomas Reginald Owens
