The object of the invention is to provide such a protective suit that effectively protects against the poisonous substances, preventing them from penetrating to any part of the body. Simultaneously the suit is arranged so as to provide an effective ventilation between the interior of the suit and the surrounding air.
According to the invention this is achieved by the fact that the suit consists of an exteriour, nonpermeable clothing which is completely resistant to the poisonous substances and an interior permanent or exchangeable porous filter-lining impregnated with agents for neutralizing the poisonous substances by destroying, absorbing or converting the poisonous substances, which lining covers the interior of the suit completely or partly, and covered ventilation channels communicating with the surrounding atmosphere.
The invention will now be described in detail with reference to the accompanying drawings which show a preferred embodiment of the invention.
FIG. 1 is a front elevational view of a protective garment according to the present invention.
FIG. 2 is a rear elevational view of a protective garment constructed in accordance with the present invention.
FIG. 3 is an enlarged view of the upper portion of the protective garment with the outer layer pulled apart to reveal the interior structure thereof.
FIG. 4 is an enlarged cross-sectional view taken along line 4-4 of FIG. 1.
A protective garment in the form of a suit 1 is uniform as will appear from FIGS. 1 or 2. The bodyencircling portion thus continues in the shape of a hood 2 having an opening 2' in front where a gas mask or a window can be inserted. The lower portion 3 of the suit continues downwardly in the shape of legs 4, which can comprise means for tightly closing the same. The upper portion comprises breast pieces 6 and a back piece 6',
the lower edge of which is free so that pockets opening downwards are formed. This is shown in a larger scale in FIG. 4. The lower portion 3 of the suit is continued upwardly via plates 6 and 6' to form a shoulder portion via a tightly secured, e.g. welded, perforated panel 10. Said panel 10 can consist of a fine mesh fabric. Inside said perforated panel 10 a filter 9 is arranged, preferably exchangeably secured as clearly seen from FIG. 4. The edges 12 of the filter here facing the suit engage the circumference of the panel 10 by the aid of a suitable connection, e.g. an adhesive fastening 11. A filter secured in this manner can be rapidly exchanged when this might be necessary.
In FIG. 3 part of the upper suit portion is shown. The reference symbols used in this figure correspond to those used in the other figures. Thus the body facing side of filters 9-is shown in FIG. 3. To the left in the figure the filter 9 is partly detached to show the perforated panel 10 underlying the filter. The filter is secured along its edge by adhesion, e.g. by an adhesive fastening ll.
It will be understood that the invention can be modified in many ways within the scope of invention stated in the claim. Thus the choice of localization of ventilation openings covered by filter can be modified in relation to the shown and described arrangement. Inside the filters 9 there can also be arranged a protective cloth if the filters themselves have a comparatively loose structure. Preferably the suit is closed by an adhesive fastening as indicated in FIG. 1 at 8, but a double zipper or other forms of gas tight fastenings can be used.
I claim:
1. A protective gamient adapted to enclose the body of a wearer to protect the wearer against poisonous gases and liquids, comprising: an outer non-permeable closing layer, said outer layer being flexible but relatively stiff and being completely resistant to poisonous gases and liquids, an inner porous filter layer secured to the interior of the outer layer, said inner layer impregnated with an agent means for neutralizing the poisonous substances, and ventilation openings in the outer layer, said inner porous filter layer completely covering said ventilation openings, said ventilation openings being covered also by the outer layer in a direction perpendicular to the plane of the openings.
2. A protective garment according to claim 1, at least a portion of said inner porous layer being removably secured to the interior of the outer layer.
3. A protective garment according to claim 1, including a perforated panel covering the ventilation openings, the inner layer being removably secured to the inner side of the panel.
