Claim:
1. A floor panel for forming a floor covering, wherein the floor panel is a laminate panel made of a board on the basis of wood, upon which one or several layers, including a decorative layer, are provided; wherein the floor panel is provided on at least two opposite edges with coupling parts made in one piece with the floor panel, as a result of which two of such floor panels can be mutually coupled to one another; wherein said coupling parts, in a coupled situation, provide for an interlocking in a direction perpendicular to a plane of the floor covering as well as in a direction perpendicular to the edges concerned and parallel to the plane of the floor covering; wherein said coupling parts comprise a tongue and a groove, said groove being bordered by an upper lip and a lower lip, the distal end of the upper lip defining a vertical plane that forms a closing plane between two of such coupled floor panels, said lower lip extending further than said vertical plane; wherein said coupling parts comprise first cooperating surfaces, on the top side of the tongue and the bottom side of the upper lip respectively, said first cooperating surfaces, in the coupled situation, working in conjunction with one another and forming a first cooperating zone, and second cooperating surfaces, on an interlocking part that is situated on the lower lip and on an opposite part of the other floor panel respectively, said second cooperating surfaces, in the coupled situation, working in conjunction with one another and forming a second cooperating zone; wherein said coupling parts are made such that two of such floor panels can be assembled by pushing towards one another by means of a movement mainly parallel to the plane of the floor covering; wherein the distal tip of said tongue, in the coupled situation, is situated in said groove past said vertical plane; wherein a distance between said vertical plane and the distal end of the lower lip is smaller than a thickness of the floor panel but larger than a distance between said vertical plane and the distal tip of the tongue in the coupled situation; wherein the distance between the distal tip of the tongue and said vertical plane in the coupled situation is smaller than the distance between a horizontal level defined by a height of said first cooperating zone and an intersection between said vertical plane and the top side of the lower lip; and wherein the floor panel shows one or both of the following characteristics:
