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.

Piston for an internal combustion engine

A piston has a piston head that is provided with a field of rings and a piston shaft which is disposed thereupon. The piston shaft is equipped with supporting shaft wall sections and rear connecting walls which interconnect the shaft wall sections, have an arched shape, and are fitted with a bolt bore. An undercut free space is provided below the annular field in the area of the bolt bore in the region of the piston head. An arched zone is disposed in the interior of the piston at the transition from the bolt bore in the direction of the shaft wall session.
