Abstract

The visor (115) is carried on a frame (114) which is hinged (K) to the helmet support (113). The helmet support carries two hydraulic cylinders (120) and (121) joining the visor support to the helmet frame. A coil spring (M2) acts against the jack. A locking device (132) acts with the bellcarnk lever (137) which operates with the cam(134). The cylinders are joined hydraulically to a control device by the lines (124) and (125).
