Pin and grommet fastener accommodating two directional offset and related methods

A pin and grommet fastener for mounting in an aperture of a first component and receiving a pin extending from a second component to couple the first and second components together comprising:

• a pin including a pin retention groove or protrusion;
• a grommet comprising:
• an inner housing defining a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction, a cooperating pin retention groove or protrusion operable to retain the pin retention groove or protrusion, and an inner housing flange having an inner housing retaining surface;
• an outer housing defining an interior with an outer housing flange having a cooperating inner housing retaining surface, and a plurality of resilient retention wings positioned to retain the first component with the outer housing flange when the outer housing is mounted within the aperture of the first component;
• a centering protrusion provided on a first of the inner housing flange and the outer housing flange;
• wherein the inner housing retaining surface engages the cooperating inner housing retaining surface, with the pin retaining receptacle of the inner housing extending into the interior of the outer housing, to slidably couple the inner housing and the outer housing together while permitting movement of the inner housing relative to the outer housing in a Y-direction between a central position and a non-central position;
• wherein the centering protrusion engages a second of the inner housing flange and the outer housing flange to initially retain the pin retaining receptacle of the inner housing in the central position within the interior of the outer housing in the Y-direction prior to insertion of the pin into the pin retaining receptacle;
• and
• wherein the second of the inner housing flange and the outer housing flange is movable against the centering protrusion in the Y-direction to permit the pin retaining receptacle of the inner housing to move out of the central position to the non-central position relative to the interior of the outer housing in the Y-direction in response to engagement of the pin against the entry ramps during insertion of the pin into the pin retaining receptacle.
