ABSTRACT:
The present invention relates to a dampening device for ball game rackets. The dampening device of the present invention includes at least one dampening element having a foot or base region, a head region and a neck or connection region arranged between the foot region and the head region. The provision of a neck or connection region leads to an optimum distance between foot or base region and head region and/or an optimum and safe positioning of the head region in the stringing plane at a preferred distance from the heart region of the racket. Preferably, the neck region is tapered or necked relative to the foot or base region and/or the head region at least in the width or thickness direction of the dampening device of the invention.
