Golf club head with reinforced front wall

A golf club head comprising:

• a hollow body having a top wall, a bottom wall, a side wall connecting said top and bottom walls and a front wall arranged for impacting a golf ball, said front wall having an inner surface and an outer surface, said front wall also having a geometric center and a thickness measured between said inner and outer surfaces along lines perpendicular thereto;
• a heel end and a toe end;
• said front wall thickness varying in a first plane disposed substantially horizontally between said top and bottom walls and in a second plane disposed substantially vertically between said heel and toe ends;
• said front wall having a bulging area of increased thickness formed on said inner surface surrounding an axis extending through said geometric center where said first and second planes intersect for reinforcing said front wall, the bulging area of increased thickness of said front wall being greatest at said geometric center and gradually decreasing in a first direction extending from said axis toward said top wall, in a second direction extending from said axis toward said bottom wall, in a third direction extending from said axis toward said heel end, and in a fourth direction extending from said axis toward said toe end, said bulging area of increased thickness causing said inner surface of said front wall to be nonplanar;
• said front wall having a first thickness dimension at said geometric center and a second thickness dimension adjacent said heel and toe ends, said first thickness dimension being greater than said second thickness dimension;
• and
• said front wall having a third thickness dimension adjacent said top and bottom walls, said first thickness dimension being greater than said third thickness dimension.
