Abstract: In a grommet for a vehicle floor cover, receptacles formed in a generally cylindrical inner surface of a female tubular body making up part of one grommet portion receive protrusions formed on a generally cylindrical outer surface of a male tubular body making up part of a second grommet portion. The bottom grommet portion may have chamfered gussets formed adjacent a bottom retention flange in order to accommodate vehicle floor mats or trays of different thicknesses. Stud holes created in respective ones of the grommets receive studs of intentionally different shape or orientation, thereby militating against installation of the floor cover upside down.

Abstract: Apparatus for adjusting the biological clock of, e.g., an intercontinental or transcontinental airline traveler includes a luminaire disposed adjacent a front edge of a seat pan of a seat. The luminaire is coupled to or includes a light source; preferably the light source is disposed remotely from the luminaire and is coupled to the luminaire by a light guide. The luminaire may have a flexible reflecting element to increase light intensity on the backs of the traveler's knees. Using the luminaire to shine bright light on the backs of the knees of the traveler permits adjustment of the biological clock of the traveler in flight.
