Abstract
Abstract A kneepad having a lower, substantially cylindrical portion for resting against the shinbone of a user, an upper partly spherical portion for resting against a kneecap of a user, and a retaining strap connected to lateral edges of the lower portion for extending about a leg of a user. The retaining strap is connected in the vicinity of a lower edge of the lower portion remote from the upper portion. From the side, the upper portion has the shape of an arc. The upper region of the upper portion, remote from the lower portion, is formed by folds that extend over approximately half of the arc. The upper portion also has a lower region interposed between the upper region thereof and the lower portion. This lower region has no folds and has essentially the same construction as the lower portion.
