a vehicle component attached to said rigid member.

9. The apparatus of claim 8, further comprising:

a vehicle attached to said vehicle component.

10. The apparatus of claim 1, wherein said rigid member includes

a horizontal reinforcing portion adjacent said top surface and extending between said at least one edge and said slot;

and

an angled reinforcing portion adjacent said bottom surface and extending from said at least one edge toward the other of said two spaced-apart edges, said horizontal and angled reinforcing portions forming a cavity therebetween and extending along said rigid member second length.

11. An apparatus for protecting a bottom surface of a component of a vehicle, comprising:

an elastomeric member having a first length substantially greater than its width, said elastomeric member having a non-planar top surface; and

a supporting member having a front, a rear, a top surface, a bottom surface, and a second length about the same as the first length, the bottom surface of said supporting member having a shape that is generally complementary to the shape of the top surface of said elastomeric member, the top surface of said supporting member defining a track oriented along the length of said supporting member, said track including a slot and a wider channel below the slot, the distance from the top surface of said supporting member to the bottom surface of said supporting member being nonconstant from front to rear;

wherein the bottom surface of said supporting member is attached to the top surface of said elastomeric member.

12. The apparatus of claim 11 wherein said supporting member is adapted and configured to have an area moment of inertia that increases in a direction from front to rear for the portion of the supporting member from the front to the forward edge of the track.

13. The apparatus of claim 12 wherein a vertical and longitudinal plane extends parallel to said slot and is centered within said slot, said elastomeric member being symmetric about the plane and said supporting member being symmetric about the plane.

14. The apparatus in accordance with claim 11 wherein the supporting member is fabricated from a single piece of aluminum.

15. The apparatus of claim 11 wherein the component is selected from the group including a bucket, a scoop, a blade, a fork or a plow, and said apparatus is fastened to the bottom of said component.

16. The guard in accordance with claim 11 wherein the vehicle is a conveyor.

17. An apparatus to protect a vehicle component, comprising:

a resilient member having a first length substantially greater than its width, said resilient member having a non-planar top surface;

a supporting member having a front, a rear, a top surface, a bottom surface, and a second length about the same as the first length, the top surface defining a slot oriented parallel to the second length of said supporting member, said slot having a width, said supporting member defining a channel below said slot, said channel having a depth, said channel having a width that is greater than the width of said slot; and

a plurality of fastener plates, each fastener plate having a bottom portion slidably received by said channel, the bottom portion having a width greater than the width of the slot, each said fastener plate having a top portion slidably received within the opening of said slot, each said fastener plate being adapted and configured such that at least part of the top portion has a height which is greater than the depth of the channel.

18. The apparatus of claim 17 wherein each fastener plate defines a hole for receiving a fastener.

19. The apparatus of claim 17 wherein each fastener plate includes a threaded portion adapted and configured to extend out of the opening of said slot.

20. The apparatus of claim 17 wherein each said fastener plate includes a hole adapted and configured to receive a separable fastener therethrough.

21. The apparatus of claim 20 wherein each hole is adapted and configured to resist rotation of a fastener extending therethrough.

22. An apparatus to protect a vehicle on a roadway from objects on the roadway, comprising:

a resilient member having a first length substantially greater than its width, said resilient member having a forward face and a rearward face, each said face being adapted and configured for upward deflection of objects on the roadway, said resilient member having a bottom surface adapted and configured for sliding contact with the roadway, said resilient member having a top and a plane extending vertically through said member; and

a supporting member bonded to the top of said resilient member with a bonding agent, said supporting member defining a slot centered about the plane and parallel to the plane, said supporting member defining a channel below said slot, said channel having a width that is greater than the width of said slot, said channel being centered about the plane and parallel to the plane.
