Blind attachment interface for filter housing assembly

A method for assembling a bezel unit with a base unit installed in an article, comprising:

• inserting a foot of a first attachment leg extending from a first position on the bezel unit into a first attachment foot receiving cavity defined within the base unit and in a fixed position with respect to the article, including by movement of the bezel unit in a first direction, the first attachment foot receiving cavity including first and second interior surfaces defining respective portions of the inside profile, the first and second interior surfaces being inwardly tapered in the first lateral direction along the first plane;
• moving the bezel unit in a second direction normal to the first direction;
• wherein moving the bezel unit in the second direction causes mutual engagement between an exterior profile of the foot with an inside profile of the attachment foot receiving cavity, both the exterior profile of the foot and the inside profile of the attachment foot receiving cavity tapering inwardly in the second direction along first and second planes positioned normal to each other and intersecting along an axis extending in the second direction, the mutual engagement between the first exterior profile and the inside profile aligning the bezel unit with the base unit with respect to the first and second planes and, further, causes first and second exterior surfaces defining respective portions of the exterior profile of the foot to contact the first and second interior surfaces along at least portions thereof to align the bezel unit with the base unit with respect to the first and second planes.
