Definitions
- the invention relates to a respiratory protection device with a signal processing unit with the features mentioned in the preamble of the main claim.
- These respiratory protection devices are not only used for the supply of breathing oxygen for pilots, but also, for example, in connection with the use of breathing apparatus for fire brigades, underground rescue teams or also for maintenance and inspection work in an atmosphere enriched with pollutants.
- the known protective device In connection with a protective helmet, the known protective device carries a signal processing unit, which is arranged in the forehead region of the helmet wearer and whose display field is outside of his field of vision. To transmit the displayed data and information, it is necessary to project the display field of the known signal processing unit into the field of view of the wearer via complex deflection optics.
- the known arrangement requires a complicated and complex deflection optics for visualization of the displayed data, which must be shock-proof in the helmet of the mask wearer to ensure a vibration and distortion-free transmission of the data into the field of view of the mask wearer.
- the field of view is significantly restricted by the imaging optics, with an optically specially designed subarea having to be provided in the viewing window of the mask, which is intended for deflecting the data intended for transmission, which are then superimposed on the usual observation of the surroundings by the viewing screen. This leads to disturbing interferences, especially with changing brightness differences. If there is no contrast, the information reflected is even invisible.
- the known display unit can therefore only be used with a special viewing window which is suitable and suitable for displaying the data
- a display unit is guided from the rear of the helmet wearer into its field of vision, the display unit pointing away from the face of the helmet wearer and its image representation being directed towards the viewer's eye by means of a deflecting lens to be adjusted.
- a deflecting lens to be adjusted.
- a similar proposal according to US-A-4 156 292 requires a holder for a display unit which can be positioned directly in front of an eye of the helmet wearer.
- the bracket starts from the side neck piece of the helmet and continues in a holding arm, at the end of which the display unit is attached.
- This known arrangement not only restricts the field of view considerably, but for the visibility of the display field a special imaging optics in the sight is necessary, which unnecessarily restricts the field of view to the external environment in the absence of a display unit with holder.
- the present invention is therefore based on the object of improving a respiratory protection device with a signal processing unit of the type mentioned in such a way that the display unit can be used universally and no optical elements restricting the field of vision are necessary.
- the object is achieved by a display unit with the features mentioned in the characterizing part of the main claim.
- the image of the surroundings remains unaffected by the narrowing or superimposition of reflected additional images.
- the amount of data to be displayed is increased further, e.g. By recording the own physiological parameters of the device wearer, information about the breathing gas supply, ambient temperature or air humidity as well as pollutant concentrations in the atmosphere and corresponding warning signals, this does not restrict the field of vision.
- the amount of data can be delivered sequentially without impairing the recognizability of the objects to be observed or reducing the attention of the wearer.
- the display field of the display unit can advantageously be covered by a magnifying lens. This also makes smaller display fields easily recognizable.
- the display unit can furthermore be expedient to provide the display unit with an optic which depicts the display field at infinity. This can be placed directly on the display unit in a simple manner and without complex deflection optics and enables the protective mask wearer to read the displayed data without fatigue even at short distances between his eye and the field of vision.
- the single figure shows the view of a respiratory protection device designed as a protective mask, which has a mask body (1) with a viewing window (2), an inner half mask (3) as well as a strap (4) and fastening tabs (5).
- the half mask (3) is connected to the mask body (1) via an extension piece (6), which opens into an outlet opening for an exhalation valve (7) and an inhalation valve (8) outside the mask body (1).
- the signal processing unit (9) consists of a processing part (10) in which the measurement signals supplied via the signal bus (11) are processed in series or in parallel and made visible in the display field (13) via a display unit (12).
- the signal processing unit (9) is housed next to the nose area of the half mask (3) on the lower attachment (6) between the half mask (3) and mask body (1), its display field (13) pointing towards the mask interior and directed towards the eyes of the mask wearer (not shown) is.
