Fastener for low profile protective helmet internal suspension padding

1. A low profile protective helmet comprising:

an outer shell of a substantially rigid impact resistant material,

said outer she having generally spherical contours to encompass the upper part of a wearer's head, wherein said outer shell is integrally formed by a center section, a front section and a rear section,

wherein said outer shell further includes an interior surface that is immediately adjacent the top of the wearer's head when the helmet is being worn, said interior surface includes a plurality of fasteners that are spaced along a bottom edge of the protective helmet, said fasteners for attaching an internal suspension padding,

first and second rib members fixed to the interior surface and adjacent to each of said plurality of fasteners such that each fastener is disposed between said first and second rib member, wherein said first and second rib members each having a first end and a second end, the first end is next to the bottom edge and the second end disposed between the bottom edge and a distal end of a horizontal extension disposed along a central portion of the center section, wherein the first end is raised from the interior surface and the second end is approximately coplanar the interior surface such that a top edge of each of the first and second rib members define a slanted surface that downwardly slants from the first end towards the second end.

2. The low profile helmet as recited in claim 1 , wherein said first and second rib members define an equal spacing therebetween such that a width of an integral head strap of a suspension liner is approximately equal to said spacing.

3. The low profile helmet as recited in claim 2 , wherein two of said plurality of fasteners are spaced apart on a first side of said center section and wherein two of said plurality of fasteners are spaced apart on a second side of said center section.

4. The low profile helmet as recited in claim 3 , wherein each of said first and second rib members is a raised ridge for stabilizing a strap portion of the internal suspension padding.

5. The low profile helmet as recited in claim 4 , wherein said first and second rib members are integral to said interior surface.

6. A low profile protective helmet comprising:

an outer shell having generally spherical contours to encompass the upper part of a wearer's head, said outer shell further includes an interior surface that is immediately adjacent the top of the wearer's head when the helmet is being worn,

a plurality of fasteners that are spaced along said interior surface and adjacent a bottom edge of said outer shell, said fasteners for attaching an internal suspension padding,

wherein at least two of said plurality of fasteners are spaced apart on a first side of a center section of said shell, and wherein at least two of said plurality of fasteners are spaced apart on a second side of said center section,

wherein each of said plurality of fasteners is sandwiched between a pair of rib members fixed to the interior surface, each of said rib members having a first end, a second end and a top slanted edge, wherein the first end is next to said bottom edge and the second end disposed between the bottom edge and a distal end of a horizontal extension disposed along a central portion of the center section, and wherein the first end is raised from the interior surface and the second end is approximately coplanar the interior surface such that said top slanted edge defines slanted surface where the first end downwardly extends towards the second end.

7. The low profile helmet as recited in claim 6 , wherein said pair of rib members define a spacing therebetween such that a width of a head strap of the suspension padding is approximately equal to said spacing.

8. The low profile helmet as recited in claim 7 , wherein each of said pair of rib members is a raised ridge for stabilizing the head strap of the suspension padding.

9. The low profile helmet as recited in claim 8 , wherein said pair of rib members is integral to said interior surface.
