资源简介：
The invention concerns an arrangement to capture passively a broken saw chain (14) of a chain saw (10) with a guide bar (12) that is arranged such that it can pivot， comprising a stationary screen (22) that forms part of a sawing box (1 1 ) and that covers a rear part of the saw. In order to achieve a cheap and efficient protection there is arranged between an end surface (20) of the screen (22) and the guide bar (12) an energy-absorbing brake means (30) that is sufficiently elastic or flexible to receive the kinetic energy from a broken saw chain (14)， to direct kinetic energy away from the chain and to regain its normal form after it has suffered an impact from and been deformed by the chain.
