Sealing pin and grommet fastener accommodating two directional offset

A water resistant 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 having inner housing walls 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 designed to retain the pin retention groove or protrusion, and an inner housing flange having an inner housing retaining surface;
• an outer housing having outer housing walls defining an enclosed interior extending from an outer housing flange, the outer housing flange including a cooperating inner housing retaining surface, and resilient retention wings extending outwardly from the outer housing walls without providing adjacent openings through the outer housing walls and designed to couple the outer housing to the first component when the outer housing is mounted within the aperture of the first component;
• a water-resistant seal positionable between the outer housing flange and the first component and designed to resist water penetration between the outer housing and the first component when the outer housing is coupled to the first component by the plurality of resilient wings;
• centering blades within the enclosed interior between the inner and outer housings and extending to locate the pin retaining receptacle of the inner housing in a central position within the enclosed interior of the outer housing in a Y-direction prior to insertion of the pin into the pin retention receptacle, wherein the centering blades are movable in the Y-direction to permit the pin retaining receptacle of the inner housing to move to a non-central position relative to the housing in the Y-direction as a result of the inner housing moving the centering blades during insertion of the pin into the pin receiving receptacle.
