Abstract
A collapse-limiting assembly for a steering system is provided. The collapse-limiting assembly comprises a housing and a moveable member. A pyrotechnic charge is located in the housing and, in response to an impact event, is caused to fire the moveable member into a discharged position and limit the amount of collapse of a steering column. The steering column includes at least two axially moveable portions that move axially relative to each other between an extended position and a retracted position. When the moveable member is fired into the discharged position, it is located in a travel path of at least one of the axially moveable portions.
