ABSTRACT:
A telescoping column includes a first tube and a second tube arranged in telescoping fashion. A locking structure is disposed between a surface formed on the first tube and a ramp disposed on the second tube. The locking structure contacts the ramp at a first elongated area of contact, and the locking structure contacts the surface at a second elongated area of contact. Relative movement of the first and second tubes in response to an impact force applied to one of the first and second tubes causes the locking structure to become wedged between the ramp and the surface, and at least a portion of the impact force between the first and second tubes is transmitted through the first and second elongated areas of contact.
