Abstract

Abstract This knee protector pad is particularly adapted for use by volleyball players and the like and includes an elastic sleeve enclosing the knee and adjacent portions of the leg of the wearer. A flat elastomeric foam pad is completely enclosed in a knit sleeve and bar tack stitching attaches spaced-apart portions of the upper and lower edges of the knit sleeve to the elastic sleeve to maintain the pad in position across the knee of the wearer and to maintain full stretchability of the elastic sleeve to facilitate doffing and donning of the knee protector pad. The foam pad has an elliptical configuration with a major axis extending transversely of the knee of the wearer and being of sufficient width to cover opposite sides of the knee, and a minor axis extending longitudinally of the knee and being substantially shorter than the major axis.
