Two-stage sun visor mounting system and method

A mounting system for attaching an accessory to a body member of a motor vehicle, the body member having an inner edge defining an opening within the body member, comprising:

• a base inserted into the opening of the body member having a base aperture;
• a clip disposed within the base aperture and the body member of the motor vehicle, the clip comprising:
• a first pair of legs;
• a second pair of legs connected to the first pair legs at a top portion of the clip;
• and
• first and second flexible tab members extending from the top portion of the clip biased outwardly between the first and second pairs of legs into engagement with the inner edge of the body member;
• and
• a cap, comprising:
• a cap base;
• a plunger extending from a first side of the cap base, the plunger inserted into the base aperture and into the clip, the plunger abutting the flexible tab members, thereby maintaining the flexible tab members in engagement with the body member;
• and
• a first multi-tab clip extending from a first side of a bottom side of the cap, comprising:
• a first sloped hook at a distal end of the first multi-tab clip, the first sloped hook in engagement with the edge of the base aperture when the cap is in a first configuration, the first sloped hook creating an interference fit with the edge of the base aperture preventing accidental removal of the cap from the base;
• and
• a first retention tab located between the first sloped hook and the bottom side of the cap, the first retention tab in engagement with edge of the base aperture when the cap is in a second configuration, the first retention tab creating an interference fit with the edge of the base aperture preventing accidental removal of the cap from the base.

A method of attaching an accessory to a body member of a motor vehicle, the body member having an inner edge defining an opening within the body member, comprising the steps of:

• inserting a base having a hook-shaped first engagement feature and a base aperture into opening with the body member;
• rotating the first engagement feature in engagement with the body member of the motor vehicle;
• inserting a clip into the base aperture and the body member of the motor vehicle, the clip defining a second engagement feature;
• and
• inserting a cap into a first position of the base, the cap comprising a cap base, a plunger extending from a central portion of a first side of the cap base, and at least one multi-tab clip extending from an edge portion of the first side of the cap base, the at least one multi-tab clip having an interference surface at a distal end of the at least one multi-tab clip, wherein the interference surface of the at least one multi-tab clip abuts the inner edge of the body member to prevent removal of the cap.
