【考案の詳細な説明】 本考案は、測定データを装置着用者の視界範囲に伝送し
かつ表示するシグナル処理ユニットを備えた呼吸保護装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a respiratory protection device with a signal processing unit for transmitting and displaying measured data in the field of view of the wearer of the device.
この種の装置は西ドイツ国特許公開第２６１８２６７号
明細書から公知である。A device of this kind is known from DE-A 26 18 267.
この呼吸保護装置は、パイロットの呼吸用酸素の供給ば

のシグナル処理ユニットの表示域を経費のかかる転向光
学系を介して着用者の視界に投影する必要がある。Known protection devices have a signal processing unit connected to the helmet, which unit is located on the forehead of the helmet wearer and whose display area is outside the wearer's field of view. The transmission of the data and information to be displayed requires that the display area of the known signal processing unit be projected into the field of view of the wearer via expensive turning optics.

別に構成されている特別な観察窓によってだけ使用可能
である。Known devices require complex and costly turning optics to visualize the displayed data in order to ensure that the data is transmitted to the mask wearer's field of view without vibration or distortion. It must be designed to be impact resistant in the mask wearer's helmet. Furthermore,
The visible range is significantly limited by the imaging optics, and the observation window of the mask must then be provided with an optically specially configured area for diverting the data for transmission. , Hence the data overlaps with the usual surrounding scenery visible through the site screen. This leads to disturbing interference effects, especially when the brightness changes. Moreover, if the contrast is insufficient, the information that is reflected into the eye becomes invisible. Therefore, the known display unit is suitable for imaging data and can only be used with a special observation window that is specially configured.
従って、本考案は前記種類のシグナル処理ユニットを備
えた呼吸保護装置を、表示ユニットが一般に使用可能で
ありかつその際に視界範囲を制限する光学素子を必要と
しないように改良するという課題に基いている。着用者
が直接見ることができるようにすべきである。The present invention is therefore based on the problem of improving a respiratory protection device with a signal processing unit of the above-mentioned type in such a way that the display unit is generally usable and in that case does not require optical elements which limit the field of view. I am It should be directly visible to the wearer.
この課題は、表示ユニットが鼻の横の部分にその表示域
が装置着用者の方向に向くように配置されていることに
より解決される。This problem is solved by arranging the display unit on the side of the nose so that the display area faces the wearer of the device.
表示ユニットを従来は使われなかった視野範囲に設ける

置着用者の注意力を狭ばめるものではない。By providing the display unit in a field of view which has not been used previously, the surrounding image is not impaired by the additional image that is narrowed or reflected and enters the eye.
For example, physiological data of the wearer of the device, information about breathing gas storage, ambient temperature or humidity, concentration of harmful substances in the atmosphere and corresponding amounts of data to be displayed, such as warning signals, can be used to improve visibility. The range is not limited. The amount of data can be sent continuously, without compromising recognition of the object to be observed or diminishing the attention of the wearer of the device.
本考案の他の実施形では表示ユニットの表示域は有利に
拡大光学系で覆われていてよい。それにより、より小さ
い表示域も簡単に認識することができる。In another embodiment of the invention, the display area of the display unit may advantageously be covered with magnifying optics. Thereby, a smaller display area can be easily recognized.
更に、表示ユニットが表示域を無限遠に結像する光学系
を備えていると有利である。この光学系は簡単に、かつ
経費のかかる転向光学系を使わずに直接表示ユニット上

は彼の目と視界との間隔が小さくても、疲れることなく
表示されたデータを読み取ることができる。Furthermore, it is advantageous if the display unit comprises an optical system for focusing the display area at infinity. The optics may simply and directly rest on the display unit without the use of costly turning optics, and for a protective mask wearer the distance between his eyes and his sight may be small, You can read the displayed data without getting tired.
