1. A golf club head, comprising:
- a body including a face, a sole, a crown, and a skirt, said face and said sole defining a loft angle, said body defining an interior, said face including a face interior surface, and said sole including a sole interior surface; and
a bias member coupled to said sole interior surface and in contact with said face interior surface at a contact location, said bias member exerting a force against said face interior surface, said bias member including an engagement member in contact with said face interior surface at said contact location and an adjustment member operatively coupled to said engagement member;
wherein;
the club head has a coefficient of restitution determined in part by said force;
said bias member is adjustable to exert a variable force against said face interior surface, thereby varying said club head coefficient of restitution;
said engagement member contains an internal, threaded orifice;
said adjustment member includes an outer surface at least a portion of which is threaded for operative engagement with said threaded orifice; and
said engagement member is constrained against rotational movement such that rotation of said adjustment member causes a vertical displacement of said engagement member, changing said contact location.

Abstract
A golf club head with a variable coefficient of restitution is disclosed and claimed. The club head includes a bias member that contacts and exerts a force against the interior surface of the face. The force exerted against the interior of the face lessens the face flexibility, and decreases the club head coefficient of restitution. The bias member can be adjusted from outside the club head, allowing the manufacturer to precisely adjust the club head coefficient of restitution.
