Abstract: An apparatus for supplying respiratory gas to a parachute jumper includes a mask which can be worn by the parachute jumper and a first respiratory gas reservoir includes a pressurized-gas vessel containing respiratory gas. The pressurized-gas vessel has an adjustable metering valve for metering respiratory gas contained in the pressurized vessel. A breathing hose connects the metering valve to the mask for conducting the respiratory gas to the mask. A second respiratory-gas reservoir contains a solid-state oxygen generator and has a manually-actuable starting device for the solid-state oxygen generator. The second respiratory-gas reservoir is connected to the breathing hose.

Abstract: A safety helmet combined with a visor (3) in a detachable connection, which is formed by holding structure located on both sides at the safety helmet shell (2). Wear properties are improved by the holding structure having rigid coupling hooks (10), which are connected to the visor (3), catch openings (11) receiving the coupling hooks (10), and hinges. A visor structure (13) that can be pivoted over the visor (3) is fastened to the hinges (12); and the detachable connection is designed such that the visor structure (13) is connected to the visor (3) in one assembly unit with it when the visor (3) is removed from the safety helmet (1).
