An energy absorptive impalement protection system is utilized in preventing impalement and minimizing injuries due to impact with the end of a concrete reinforcing bar or other similar type of bar. The energy absorptive impalement protection system is comprised of a protective cover apparatus that has a simplified construction comprised of a base that is removably attached to an end of a reinforcing rod, a metal band on the base that surrounds the rod end and reinforces the base against side-to-side movement relative to the rod in response to an impact force, a metal impact plate on the base that absorbs and distributes the force of impact, and a resilient, compressible and stretchable cover on the base that together with the base encloses the band and cover in the apparatus and also absorbs some of the force of impact.

1. A protective cover apparatus for attachment to an end of a rod to absorb impact energy from an object impacting the end of the rod, the apparatus comprising: an impact member having opposite first and second surfaces, a perimeter edge that surrounds and separates the first and second surfaces, the impact member first surface having a convex configuration and the impact member second surface having a concave configuration;a base having opposite first and second ends, the base first end being constructed to attach to the end of a rod and support the base on the end of a rod, and the base second end engaging with the impact member and supporting the impact member on the base with the impact member first surface facing towards the base second end and the impact member second surface facing away from the base;a band having opposite interior and exterior surfaces, wherein the base second end engages with and supports the band with the band interior surface capable of surrounding the end of a rod received by the base first end and the band is positioned between the base and the impact member; anda cap having opposite first and second surfaces, the cap first surface engaging with the impact member second surface and the cap second surface being an exterior surface of the protective cover apparatus. 2. The apparatus of claim 1, further comprising: a cap having opposite first and second surfaces, the cap first surface engaging with the impact member second surface and the cap second surface facing away from the base and the impact member. 3. The apparatus of claim 2, wherein: the base and the cap completely enclose the impact member. 4. The apparatus of claim 1, wherein: the impact member is a plate having a cup-shaped configuration. 5. The apparatus of claim 4, wherein: the impact member is deformable from the cup-shaped configuration toward a planar configuration in response to an impact force on the apparatus that is directed toward the impact member second surface. 6. The apparatus of claim 1, wherein: the impact member and the band are detached. 7. The apparatus of claim 1, wherein: the impact member has a disk configuration of metal; and,the band has a cylindrical configuration of metal. 8. The apparatus of claim 1, wherein: the base has a groove recessed into the base second end; and,the band is received inside the base groove. 9. The apparatus of claim 1, wherein: the impact member has a disk configuration and is constructed of metal;the base has a tubular configuration and is constructed of plastic;the band has a cylindrical configuration and is constructed of metal; and,the cap has a disk configuration and is constructed of a resilient, compressible and stretchable material. 10. A protective cover apparatus for attachment to an end of a rod to absorb impact energy from an object impacting the end of the rod, the apparatus comprising: an impact member having a cup-shaped configuration with opposite first and second surfaces and a perimeter edge that surrounds and separates the first and second surfaces, where the first surface defines an exterior surface of the cup-shaped configuration and the second surface defines an interior surface of the cup-shaped configuration, the second surface surrounding an interior volume of the cup-shaped configuration;a base having opposite first and second ends, the base first end being constructed to attach to the end of a rod and support the base on the end of a rod, the base second end engaging with the impact member first surface and supporting the impact member on the base with the impact member first surface opposing the base second end and the impact member second surface facing away from the base, the base first end having an interior bore dimension which is dimensioned to receive the end of a rod;a band mounted on the base, the band having opposite interior and exterior surfaces and the band interior surface extending around the base interior bore and the band is positioned between the base and the impact member; anda cap having opposite first and second surfaces, the cap first surface engaging with the impact member second surface and the cap second surface being an exterior surface of the apparatus. 11. The apparatus of claim 10, wherein: the impact member is a metal material; and,the base is a plastic material. 12. The apparatus of claim 10, wherein: the impact member first surface is a convex surface and the impact member second surface is a concave surface. 13. The apparatus of claim 10, wherein: the impact member is deformable from the cup-shaped configuration toward a planar configuration in response to an impact force on the apparatus that is directed toward the impact member second surface. 14. The apparatus of claim 10, wherein: the band is cylindrical and is a metal material. 15. The apparatus of claim 10, wherein: the band and the impact member are detached. 16. The apparatus of claim 10, wherein: the base has an annular groove recessed into the base second end and the band is received in the annular groove. 17. The apparatus of claim 10, wherein: the impact member has a disk configuration and is constructed of a metal material;the base first end has a cylindrical configuration and the base second end has a disk configuration, the base being constructed of a plastic material;the band has a cylindrical configuration and is constructed of a metal material; and,the cap has a disk configuration and is constructed of a resilient, compressible and stretchable material.
