In the following embodiments is illustrated as a rubber cuff with a textile-like ABC protective suit material is connected.

First, on hand of the 1 to 7 shows where impermeable cuffs are used in an ABC protective suit and what their purpose is. Then, it will be discussed in detail how a connection area between the impermeable cuff 40 and the textile-like ABC protective suit material 1 is designed.

The 1 to 3 Illustrate that the impermeable cuff is a hood cuff 40a for gas and particle tight connection of a gas mask 3 is that in 1 is drawn. The hood cuff 40a rubber has inside an opening with a sealing bead, which is elastic on the edge of the gas mask 3 rests. In addition, in the 1 to 3 shown that the attachment of the hood cuff 40a indirectly via an annular relief strip 41 he follows. This allows the gas mask to be easily moved back and forth during insertion and removal without the head portion of the ABC protective suit being subjected to tensile loading. The relief strip 41 consists of the same ABC protective suit material used for the head, torso and limb area. Most details shows that 3 , In it you can see that the relief strip 41 on the one hand with the ABC protective suit material 1 is sewn and the other with the hood cuff 40a connected is. The drawn detail VIII, from the roughly a reinforcing strip 50 and a seam sealing tape 60 will emerge later in connection with the 8th erläutet.

The 4 and 5 Illustrate that the impermeable cuff is a leg cuff 40c For gas and particle tight connection of an impermeable boot 6 is. A peculiarity of the leg cuff 40c is that she is using a stiff retaining ring 7 is in a functional context. As in 5 shown prevents the rigid retaining ring 7 in that the flexible boot material can buckle inwards. This exercises the externally stretched leg cuff 40c in the investment area a contact pressure on the boots. This gives the seal. The drawn detail VIII is later in the context of the 8th erläutet.

The 6 and 7 Illustrate that the impermeable cuff is an arm cuff 40b for gas and particle tight connection of an impermeable glove 4 is. In contrast to the previous example of the leg cuff arm sleeve is provided without the interaction with a retaining ring. Because the stiffness of the arm cuff is so great that the glove is stretched in the investment area and can apply a contact pressure for sealing. The drawn detail VIII is later in the context of the 8th erläutet.

The seam tape 60 is in the 4 to 7 not drawn in order to achieve a good clarity of the drawings.

As already mentioned, the 8th the enlarged detail VIII, as they are in the 3 . 5 and 7 is drawn.

The impermeable cuff 40 is the hood cuff 40a after the 1 to 3 , or the arm cuff 40b after the 6 and 7 or the leg cuff 40c after the 4 and 5 , The impermeable cuff 40 is made of butyl rubber. The thickness of the butyl rubber used for the hood, arm and leg cuffs is different in each case and is in the range between 0.7 mm to 2.5 mm.

The impermeable cuff 40 and the permeable ABC protective suit material 1 overlap and form a circular connection area 93 ,

In the connection area 93 are the impermeable cuff 40 and the ABC protective suit material 1 over closing seams 91 connected with each other.

In the connection area 93 is additionally a reinforcing strip 50 arranged. The reinforcing strip 50 is a rubberized fabric. The reinforcing strip 50 is over an adhesive layer 51 flat with the cuff 40 connected.

In other words, the cuff points 40 a round border for sewing on. On this peripheral edge is the reinforcing strip 50 glued.

The reinforcing strip 50 is a strip of rubberised fabric. The fabric is coated on both sides with butyl rubber. The double-sided gumming proves to be advantageous in terms of strength and double-sided bonding. The thickness is 0.5 mm. This can be in the range between 0.3 and 0.9 mm. The fabric of the reinforcing strip 50 consists of polyester or polyamide. The fabric has a high tensile strength and low stretchability in the warp and weft directions. Preferably, the reinforcing strip is designed as a canvas, Rippstop- or Taffetgewebe. Also suitable would be a twill or satin weave.

For gluing the reinforcing strip 50 An adhesive and primer adhesive system designed for bonding butyl rubber was used.

In the connection area 93 are the impermeable cuff 40 , the glued reinforcing strip 50 and the permeable protective suit material 1 overlapping edge to edge while preserving a finishing surface 94 placed. The closing surface 94 is U-shaped in the connection area with a particle-tight seam tape 60 edged. The seam tape 60 is an aerosol impermeable nonwoven filter cloth. Alternatively, the seam tape could 60 Also be designed as a semi-permeable membrane or as a thin, rubberized fabric. The attachment of the seam tape 60 via border seams 92 ,

The cuffs 40 are cut wide to avoid tensile loads on the seams as the suit carrier moves.

In 8th is a permeable ABC protective suit material 1 illustrated. It consists of an outer fabric 10 , a filter layer 20 and an inner laminate 30 ,

The outer fabric 10 , which forms the outermost layer, consists in the present example of 98% polyester with a 2% content of antistatic fibers.

The filter layer 20 is an aerosol impermeable nonwoven filter fabric with very fine pores and high air permeability. The nonwoven filter cloth consists of two to five individual nonwoven filter cloth layers, the are connected in a dot-matrix manner. The nonwoven filter cloth has a pore size smaller than 1 μm and consists of microfibers having a diameter of 0.1 to 10 μm. The fleece filter fabric reduces more than 99% of harmful fine particles with a size of 1 μm (NATO Stanag 4548). Its air permeability is between 380 and 500 mm / s (DIN EN ISO 9237). The basis weight is 45 g / m ² and the thickness is 0.40 mm. For the seam tape 60 can be the same material as for the filter layer 20 be used.

The inner laminate 30 consists of individual permeable layers with an adsorbent layer containing activated carbon.

In contrast to 8th is in 9 a semipermeable ABC protective suit material 1' illustrated. It consists of an outer fabric 10 ' and an inner laminate 30 ' ,

The outer fabric 10 ' consists mainly of polyamide. The inner laminate 30 ' has no Adsorberlage of activated carbon. Instead, the inner laminate has 30 ' a layer of a semipermeable membrane. Otherwise, that's right 9 with the 8th match. Same reference numerals in FIG 9 and 8th concern the same elements.
