Abstract
A safety helmet with a helmet shell, with a bearing ring, with a rotatable actuating element () and with a transmission unit (). The transmission unit () transmits a rotation of the actuating element to the bearing ring, so that the head size provided is changed. A helmet shell-side transmission piece () is non-rotatably connected to the actuating element () such that they rotate in unison, and a bearing ring-side transmission piece () is connected mechanically to the bearing ring. The helmet shell-side transmission piece () can move both relative to the actuating element () and relative to the bearing ring-side transmission piece () linearly in two opposite directions. The distance between the actuating element () and the bearing ring can be changed thereby.
