The lock bolt has a bolt tip (2) a bolt head (3) whose back wall (4) is intended to rest against a housing pin for sliding this pin into the rotary closure cylinder (24). The bolt tip (2) is supported on the bolt head (3) with a spring engaged between the bolt tip (2) and the bolt head (3) so that it can slide in a limited fashion between an inner and an outer position. The bolt head (3) has a longitudinal bore (5) in which the bolt tip (2) is supported so that it can slide. The lock bolt to a large extent prevents unlocking attempts in which vibrational movements are exerted on the tumblers.

[ What is claimed:] [1.] A lock bolt in a rotary closure cylinder (24) of a safety lock, said rotary closure cylinder (24) having a housing spring acting on a back end of an associated housing pin, said lock bolt having a bolt tip (2) and a bolt head (3) both of which are slidably located in a rotor

[ What is claimed:] [1.] A lock bolt in a rotary closure cylinder (24) of a safety lock, said rotary closure cylinder (24) having a housing spring acting on a back end of an associated housing pin, said lock bolt having a bolt tip (2) and a bolt head (3) both of which are slidably located in a rotor of the safety lock, said bolt head (3) having a back wall engaged against the associated housing pin for sliding the associated housing pin into the rotary closure cylinder (24) when the rotor of the safety lock is rotated by a corresponding key,wherein the bolt tip (2) is supported in the bolt head (3) so that it is slidable longitudinally in a limited fashion between an inner position and an outer position;wherein spring biasing means are engaged between the bolt tip (2) and the back wall (4) of the bolt head (3) for forcing the bolt tip (2) away from the bolt head (3);said spring biasing means exerting a force between the bolt tip (2) and the bolt head (3) substantially less than a force exerted by the housing spring on the back end of the associated housing pin; andwhereby a vibrational movement exerted on the bolt tip (2) is absorbed by said spring biasing means and is not transmitted to the bolt head (3) so that said associated housing pin is not slid into said rotary closure cylinder (24) to permit unauthorized opening of the safety lock.
