Abstract:
1. A grommet for use in cladding one of a plurality of stud retention holes made in respective vehicle foot well covers having different thicknesses, the grommet comprising: a top grommet portion having a top male tubular body formed around an axis and having an outer surface, a top floor cover retention flange extending radially outwardly from the outer surface of the top tubular body; a bottom grommet portion having a bottom female tubular body formed around the axis and having an inner surface and an outer surface, a bottom floor cover retention flange extending radially outwardly from the outer surface of the bottom tubular body, the top tubular body sized to be received into the bottom tubular body; an inner surface of the female tubular body being generally cylindrical and having a length, at least one receptacle formed in the inner surface of the female tubular body to extend radially outwardly therefrom, the receptacle disposed adjacent to an upper axial end of the female tubular body, the receptacle having an axial depth as measured from the upper axial end; at least one protrusion radially outwardly extending from the outer surface of the male tubular body and adapted to be received in said receptacle of the female tubular body, the protrusion of the male tubular body cooperating with the receptacle of the female tubular body to prevent rotation of the male tubular body relative to the female tubular body around the axis, the axial depth of the receptacle being less than the length of the inner surface of the female tubular body, thereby preventing the assembly of the female tubular body in an upside down condition relative to the male tubular body; a generally cylindrical outer surface of the female tubular body, an orienting feature projecting radially outwardly from the outer surface of the female tubular body, the orienting feature being in angular alignment with said at least one receptacle; and a plurality of angularly spaced-apart chamfered gussets each formed to join the outer surface of the bottom tubular body to the lower floor cover retention flange, a right cross sectional area of each gusset increasing as a function of its axial proximity to the lower floor cover retention flange.
