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.

Safety helmet with telescopically adjustable head size

A gas mask, for use with a gas filter or with a demand oxygen system, includes an elastic mask body, a connector and a counter-support. The elastic mask body is configured to be placed over the mouth and the nose of a user of the gas mask. The connector is attached to the elastic mask body and is configured to fix a gas filter or an end piece of a tube in a mount of the connector. The counter-support is attached to the elastic mask body and has a contact area for a support projection of the connector. The connector and the counter-support are arranged such that a force exerted on the connector in a direction of the user acts on the contact area of the counter-support at least partially via the support projection. The support projection is integrated at the connector by manufacturing in one piece.
