We claim: 1. A curb inlet filter for filtering out sediments, debris or the like flowing into a curb inlet, comprising: a filter body, including (a) a water permeable, substantially rigid, elongated frame having an upstream side, facing away from the curb, and a downstream side thereof, facing toward the curb and curb inlet, (b) an elongated filter cover formed around at least one of said sides of said frame, said filter cover being formed of a filtration material to filter out sediments, debris or the like; a weight support attached to a bottom of said filter body for supporting a weight; and a support strap connecting said weight support to an upper portion of said filter body. 2. The curb inlet filter of claim 1, wherein said frame includes a plurality of spacers, at least one each disposed at opposing ends of said frame and on said downstream side thereof, such that overflow water may flow into a gap formed between said spacers and said downstream side of said frame. 3. The curb inlet filter of claim 1, wherein said filter cover entirely surrounds said frame. 4. The curb inlet filter of claim 3, wherein said filter cover is a cylindrical sleeve, in which said frame is disposed, said sleeve being closed on opposing ends thereof. 5. The curb inlet filter of claim 3, wherein said filter cover has a closable seam along a longitudinal side thereof for retaining said frame therein. 6. The curb inlet filter of claim 1, wherein said filter cover is a woven fabric. 7. The curb inlet filter of claim 6, wherein said woven fabric is a multidimensional fabric. 8. The curb inlet filter of claim 7, wherein said multidimensional fabric is a 3 dimensional fabric. 9. The curb inlet filter of claim 1, wherein said filter cover is a non-woven material. 10. The curb inlet filter of claim 1, wherein said weight support is removably attached to the bottom of said filter body. 11. The curb inlet filter of claim 10, wherein said weight support is removably attached to the bottom of said filter body by a plurality of connectors. 12. The curb inlet filter of claim 1, wherein said weight support is a bag for receiving a weight therein. 13. The curb inlet filter of claim 12, wherein said bag is water proof and has a closable filling hole, for retaining water therein. 14. The curb inlet filter of claim 1, wherein said frame includes a plurality of individual elements which are detachably attached to one another. 15. The curb inlet filter of claim 14, wherein each of said individual elements includes one or more spacers, each spacer formed on a downstream side of one of said individual elements. 16. The curb inlet filter of claim 1, further comprising a flexible insert formed on a bottom portion of said frame, in order to adjust to a contour of road surfaces. 17. The curb inlet filter of claim 16, wherein said flexible insert is foam. 18. The curb inlet filter of claim 16, wherein said flexible insert is formed of extruded rubber. 19. The curb inlet filter of claim 1, further comprising a handle formed on an upper portion thereof. 20. The curb inlet filter of claim 1, further comprising tie back straps formed on an upper portion of said filter body. 21. A curb inlet filter for filtering out sediments, debris or the like flowing into a curb inlet, comprising: a filter body, including (a) a water permeable, substantially rigid, elongated frame having an upstream side, facing away from the curb, and a downstream side thereof, facing toward the curb and curb inlet, and (b) an elongated filter cover formed around at least one of said sides of said frame, said filter cover being formed of a filtration material to filter out sediments, debris or the like; and a weight support attached to a bottom portion of said filter body, and extending on the downstream side thereof, for supporting a weight, for fixing the filter body against an upstream side of the curb inlet.
