Crashstop Design for Facilitating Modifications with Minimal Design Impact

      Disclosed is a crashstop design which geometrically allows for
modifications to the stiffness, stop location, and/or mounting
features independently, thus minimizing the impact to the overall
design.

      The crashstop stiffness, stop location, and mounting conditions
are each defined by independent features.  The stiffness is defined
by the size of the inner diameter (1), the stop location is defined
by the diameter of the boss (2), and the mounting conditions are
defined by the top and bottom press fit diameters (3) as shown in the
Figure.

      With this design the inner diameter (1) can be modified to
change the crashstop stiffness without affecting the stop location.
Likewise, as the stop location requirements change, the diameter of
the boss (2) can be increased or decreased accordingly without
impacting the crashstop stiffness.  Furthermore, each time a change
is made to either the inner diameter (1) or the diameter of the boss
(2), it does not affect the mounting conditions of the top and bottom
press fit diameters (3).  Therefore, as crashstop stiffness and
location requirements change within a single program, or with new
models, modifications can be made as necessary to the parameter of
interest, without altering the characteristics of the other
parameters.
