The number and configuration of the protrusions can be designed to provide a press-fit insertion force of 50 Newtons or less, and to provide a friction retention force sufficient to retain the annular collar within the recess under its own weight, throughout relevant tolerance ranges for the mating walls.

Abstract: A pin and grommet fastener includes a grommet that defines a central aperture and includes at least two adjacent longitudinally extending leg members that each include a frame, a knuckle and a tether.

Abstract: An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. Centering protrusions of one housing can engage the other housing to initially retain the pin retaining receptacle of the inner housing in a central position within the interior of the outer housing in the Y-direction prior to insertion of the pin into the pin retaining receptacle. The other housing can be movable against the centering protrusion to permit the pin retaining receptacle of the inner housing to move out of the central position 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.
