Abstract
A piston includes a piston head, a ring zone and a piston skirt having load-bearing skirt wall sections and rear connecting walls which interconnect the skirt wall sections and piston-pin bosses which run on a boss axis that is set back from a piston axis and penetrate the connecting walls. The peripheral lower edge of the connecting walls is convex in relation to an axis and the upper edge of said connecting walls, preferably below the ring zone, is concave in relation to an axis perpendicular to a piston-pin axis. The piston is equipped with a reinforced section in the vicinity of the piston head running radially behind the ring zone.
