1. A joint protector of a sheet-shaped flexible material, including an essentially tubular body, which is provided with a curved configuration for adaptation to a joint, so that the joint protector defines a convex area for adaptation to an extreme portion of the joint, and which is sewn together with at least one seam, essentially longitudinally of the protector, between a first edge of a first material portion and a second edge of a second material portion, said joint protector comprising the seam between said edges extending along a curve, which defines a recessed area of material of the first material portion at an essentially central portion of the first edge, and which defines an enlarged area of material of the second material portion at an essentially central portion of the second edge, the first material portion being provided with a contracting action to the recessed area of material through the seam for achieving a curved configuration of the tubular body by an extension of the recessed area of material exceeding an extension of the enlarged area of material in an unloaded condition, and a length of the first edge exceeding a length of the second edge in the unloaded condition, the first material portion belonging to at least two first pieces of material.
