Embodiment Construction

[0063] exist figure 1 A partial view of a preferred embodiment of the breathing hose 1 according to the invention arranged at the breathing hose port 16 is shown schematically in side view. The breathing hose 1 has a hose body 3 which extends along a hose axis 4 . Arranged on the first hose end 5 of the breathing hose 1 is a conical end region 12 which widens towards the first hose end 5 . The first hose end 5 of the breathing hose 1 has a closing ring 13 which preferably consists of a solid material, in particular rubber. Arranged on the closing ring 13 is a web-like molding 7 which extends away from the hose body 3 along the hose axis 4 . The molded body 7 has a first section 8 connected to the closed ring 13 and a second section 9 arranged at the end of the first section 8 facing away from the closed ring 13 . An obtuse angle α is formed between the first section 8 and the second section 9 . Anti-slip devices 10 with grooves are arranged on both sides on the second sect...

Abstract

A breathing tube for a respirator is provided and includes a flexible tube body with a tube axis, a first tube end and a second tube end. A molding is formed at the first tube end. The molding extendsat least partially along the tube axis away from the first tube end of the tube body. A respirator may be provided, including the breathing tube, a breathing unit and a breathing air supply device. Abreathing tube port is formed at each of the breathing unit and at the breathing air supply device for connecting the breathing tube. A mounting device is formed at at least one breathing tube port for mounting the molding of the breathing tube.

Description

technical field [0001] The invention relates to a breathing hose for a respirator, in particular a rebreather. Furthermore, the invention relates to a breathing protector with such a breathing hose. Background technique [0002] Freely portable breathing protectors are known, in which a breathing device, such as a protective mask covering the mouth or face, is connected by means of a flexible breathing hose with a portable supply of breathing air, such as a compressed air bottle, an air filter, etc. , air cooling device or the like is connected in fluid communication. The breathing tube is usually of flexible design in order to ensure a flexible, fluid-connected connection of the breathing device to the breathing air supply device. In this way, in the coupled state, a relative movement of the breathing device and the breathing air supply device is possible, thereby improving operability and user comfort. In the case of portable respirators, a distinction is basically made...
