Internally collapsible steering column assembly
Abstract:
A steering column assembly for an automotive vehicle that includes an inner column tube, a steering shaft supported at least in part by the inner column tube and having a longitudinal axis, a top bracket adapted for receiving a least a portion of the steering shaft and for mounting the steering column assembly within the automotive vehicle, and a telescoping motor subassembly adapted for selectively driving the steering shaft in a fore or aft direction. A telescoping motor subassembly mounting structure is coupled during normal operation to a column housing, the telescoping motor subassembly and the inner column tube, wherein the telescoping motor subassembly mounting structure is adapted to detach from the column housing in the event of an impact exceeding a predetermined first impact load. A plastically deformable energy absorption device is adapted to be carried least partially by the telescoping motor subassembly mounting structure and is fixed in place relative to the column housing during normal operation for maintaining the steering column assembly in an operational position. The energy absorption device absorbs energy by plastic deformation during impact after the telescoping motor subassembly starts to translate along the column housing, and wherein during the impact, the column housing remains in a fixed position.
