Zusammenfassung:Chain saw guide bar comprising three plates joined by welding, having a nose, a clamping area and a guiding groove for the chain, where the bending stiffness in a zone immediately in front of the clamping area is increased by omitting welds in the zone to make sure that the compressed plate buckles outward when overloaded. The zone extends in the longitudinal direction of the bar for a distance greater than the groove depth and less than the bar width.
