Abstract
Embodiments of an iron-type golf club head comprising a high moment of inertia and a damping system. The damping system includes an insert covering a lower portion of the back face and a badge covering an upper portion of the back face. The damping system covers a large proportion of the back face and provides a club head with desirable sound and feel characteristics.
Claims20
An iron-type golf club head comprising:
- a strike face comprising a geometric center and a back face opposite the strike face;
- a heel portion;
- a toe portion opposite the heel portion;
- a top rail;
- a sole opposite the top rail;
- a rear wall extending upward from the sole at least partially towards the top rail;
- wherein the rear wall comprises a rear wall top edge;
- an insert cavity formed by at least an inner surface of the rear wall and a lower portion of the back face;
- wherein the insert cavity comprises an insert cavity opening extending between the rear wall top edge and the lower portion of the back face;
- wherein the insert cavity comprises an insert cavity base formed by an inner surface of the sole;
- a damping system comprising:
- an insert disposed within the insert cavity;
- a badge attached to an upper portion of the back face;
- wherein the insert and the badge are in contact with back face;
- wherein the damping system defines a damping system coverage area measured as a combined surface area of the back face contacted by the insert and the badge;
- wherein the damping system coverage area is greater than 3.0 in2;
- and
- wherein the damping system coverage area is greater than 85% of an available surface area of the back face.
