Knee pad device

1. A knee pad apparatus, comprising:

a body having a central portion positioned in between two opposing side portions of said body;

said body having a curved exterior surface extending across said central portion;

said body having a cavity defined by a curved interior surface extending across said central portion and said opposing side portions, said cavity positioned on an opposite side from said exterior surface;

said cavity for positioning of a knee of a user therein to an as-worn position of said knee pad, with said user kneeling upon said curved interior surface and having said side portions positioned on opposing sides of said knee;

a projection body in an engagement to said central portion of said body;

a first plurality of elongated projections positioned on said projection body;

a second plurality of elongated projections positioned on said projection body;

said first plurality of elongated projections each having a first raised end abutting a first side of a recessed channel area, and each of said first plurality of elongated projections extending away from said first raised end thereof, toward a first one of said opposing side portions, to a second raised end thereof;

each of said second plurality of elongated projections having a first raised end thereof abutting a second side of said recessed channel area opposite said first side thereof, each of said second plurality of elongated projections extending away from said first raised end thereof, toward a second one of said opposing side portions to a second raised end thereof;

contact of said recessed channel area upon a support surface along with each said first plurality of elongated projections, and said second plurality of elongated projections, on opposite sides of said recessed channel area, forms a non-rolling support for said curved exterior surface of said kneepad upon said support surface during use in said as-worn position, said non-rolling contact preventing rolling of said body in a direction toward either of said side portions.

2. The knee pad apparatus of claim 1 , additionally comprising:

said first plurality of elongated projections abutting said first side of said recessed channel area, being aligned with said second plurality of elongated projections positioned on said projection body abutting said second side of said recessed channel area.

3. The knee pad apparatus of claim 1 , additionally comprising:

said projection body having a perimeter edge;

said recessed channel area located in a central area of said projection body in-between opposing sides of said perimeter edge and;

said second raised ends of said first plurality of elongated projections and said second plurality of elongated projections extending toward said perimeter edge of said projection body radially around said recessed channel area.

4. The knee pad apparatus of claim 3 wherein said engagement of said projection body with said central portion of said body, is a removable engagement between tabs extending from said perimeter edge of said projection body and tab apertures located in said curved exterior surface.

5. The knee pad apparatus of claim 1 additionally comprising:

a pad component having an exterior surface configured to engage with said interior surface of said cavity; and

said pad component having an interior surface opposite said exterior surface for a surrounding contact with said knee of said user.

6. The knee pad apparatus of claim 5 additionally comprising:

vent channels depending into said exterior surface of said pad component; and

vent apertures communicating between said interior surface and said vent channels, whereby air is communicable through said vent channels to said interior surface of said pad component.

7. The knee pad apparatus of claim 5 additionally comprising:

said pad component having a central pad portion extending to opposing sidewall pad portions on opposite sides of said central pad portion;

said central pad portion formed of foam material having a first density of substantially 25 shore; and

said sidewall pad portions formed of a foam material having a second density of substantially 45 shore.
