Golf club head
InactiveUS20060116218A1Increase deflectionSlow down the spin rateGolf clubsRacket sportsElastomerCoefficient of restitution
A metal wood golf club head is provided having a front face with an impact zone including a compliant area. Preferably, the compliant area is disposed in an upper portion of the front face. Preferably, a through-slit is provided in the front face to form the compliant area. The through-slit may be an elongated slot substantially parallel to a top of the front face and may include an elastomeric reinforcement. The compliant area creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The compliant area upwardly shifts the coefficient of restitution to the geometric center of the face and thereby increases the carry distance of a golf ball hit off the club head.
