A pivot rod connection interface cover for covering the connection interface of a sun visor pivot rod which protects occupants from head impact injury in the event of a crash, yet allows the sun visor to both pivot and rotate in a fully normal and familiar manner. The pivot rod connection interface cover is composed of a base member and a cover member rotatively connected thereto. The base member is affixed to the roof of the vehicle and preferably serves as a pivot rod support which allows rotation of the pivot rod with respect to the roof. The cover member has a preferably hemispherical dome shape that snappingly engages the base member so as to be rotatable therewith and receives therewithin the pivot rod connection interface (ie., including the elbow). Preferably, but not necessarily, internal to the cover member are left and right guide walls which serve as crush features, as well as assistance to guiding the pivot rod therewithin. A visor pivot rod may be integrally connected to the connection interface cover.

1. A sun visor apparatus for being connected to a roof of a motor vehicle, comprising:a sun visor;a pivot rod having a main portion, an end portion, and an elbow therebetween, wherein said sun visor is pivotally mounted to said main portion of said pivot rod;a first connection connecting said end portion rotatably to the roof of the vehicle;a base member having a central aperture for receiving therethrough said end portion;a second connection connecting said base nonrotatably to the roof;a cover member having a cover wall having an exterior surface of a selected shape, said cover member having an equitorial terminus, said cover member having an inner periphery formed at said equitorial terminus, said cover wall having a portal formed therethrough, said cover member having an interior hollow defined by an internal surface; anda third connection connecting said cover member to said base member so that said cover is rotatable in relation to said base member;wherein when said base member is connected to said cover member, the elbow is covered by said cover member, and said main portion exits said cover member through said portal; andwherein when said pivot rod is rotated with respect to the roof, said cover member rotates with said pivot rod. 2. The sun visor apparatus of claim 1, wherein said third connection comprises:an annular slot being formed in said inner periphery adjacent said equitorial terminus; andsaid base member having a perimeter, said base member having tab means located at said perimeter for snappingly interfacing with said annular slot. 3. The sun visor apparatus of claim 2, wherein said tab means comprises a plurality of tabs, each tab curvably following a respectively adjoining portion of said perimeter, each tab comprising:a lower chamfer;an upper chamfer; andan apex between said lower and upper chamfers, wherein said apex is disposed radially outward with respect to said perimeter;wherein each tab is resiliently deformable in an inwardly radial direction with respect to said perimeter. 4. The sun visor apparatus of claim 3, wherein said plurality of tabs comprises three tabs equidistantly spaced around said perimeter. 5. The sun visor apparatus of claim 3, wherein said portal has a flat face generally perpendicular to a plane defined by said equitorial terminus. 6. The sun visor apparatus of claim 5, wherein said portal comprises a flat-faced arch. 7. The sun visor apparatus of claim 3, wherein when said base member is connected with said cover member, said perimeter is juxtaposed said inner periphery such that said base member is substantially flushly received into said cover member. 8. The sun visor apparatus of claim 5, wherein said selected shape is a generally hemispheric dome shape. 9. The sun visor apparatus of claim 5, wherein said selected shape is a generally curvaceous shape having a rounded nose and a flat face, wherein said portal is located at said flat face. 10. The sun visor apparatus of claim 1, further comprising a crush feature comprising a pair of mutually parallel guide walls connected with said inner surface, said pair of guide walls straddling said portal and being equidistantly spaced from a center of said inner periphery. 11. The sun visor apparatus of claim 10, wherein said third connection comprises:an annular slot being formed in said inner periphery adjacent said equitorial terminus; andsaid base member having a perimeter, said base member having tab means located at said perimeter for snappingly interfacing with said annular slot. 12. The sun visor apparatus of claim 11, wherein said tab means comprises a plurality of tabs, each tab curvably following a respectively adjoining portion of said perimeter, each tab comprising:a lower chamfer;an upper chamfer; andan apex between said lower and upper chamfers, wherein said apex is disposed radially outward with respect to said perimeter;wherein each tab is resiliently deformable in an inwardly radial direction with respect to said per imeter. 13. The sun visor apparatus of claim 12, wherein said plurality of tabs comprises three tabs equidistantly spaced around said perimeter. 14. The sun visor apparatus of claim 12, wherein said portal has a flat face generally perpendicular to a plane defined by said equitorial terminus. 15. The sun visor apparatus of claim 14, wherein said portal comprises a flat-faced arch. 16. The sun visor apparatus of claim 12, wherein when said base member is connected with said cover member, said perimeter is juxtaposed said inner periphery such that said base member is substantially flushly received into said cover member. 17. The sun visor apparatus of claim 14, wherein said selected shape is a generally hemispheric dome shape. 18. The sun visor apparatus of claim 14, wherein said selected shape is a generally curvaceous shape having a rounded nose and a flat face, wherein said portal is located at said flat face.
