[0027] FIG. 4 capsule with coolant inside.

[0028] A head protection bonnet 1, shown in principle in the sectional view in FIG. 1, has a four-layer structure. It has an outer layer 3, a damping layer 1.1 at least indirectly adjacent to the outer layer 3 and an inner fabric layer 1.2. A first intermediate layer 1.3 and a second intermediate layer 1.4 are arranged between the damping layer 1.1 and the fabric layer 1.2, whereby the first intermediate layer 1.3 is placed between the inner layer 1.2 and the second intermediate layer 1.4. The damping layer 1.1 is preferably made of foam and forms a cushioning and impact protection layer.

[0029] The first intermediate layer 1.3 is designed as a so-called spacer layer and ensures a spatial distance between the inner layer 1.2 and the second intermediate layer 1.4. This spatial distance allows for an improved welding application and removal function of the inner layer 1.2.

[0030] The inner layer 1.2 also has a cooling medium 2, which is integrally accommodated or arranged in the inner layer 1.2 and is in the form of paraffin. The cooling medium has a corresponding heat capacity and ensures a corresponding heat absorption for cooling purposes of the scalp of the wearer of the head protection bonnet 1.

[0031] In the embodiment example in FIG. 2, the head protection bonnet 1 is integrated into a steel helmet or ballistic helmet 4 as an inner lining. The associated functional properties are as described for the embodiment example in FIG. 1.

[0032] FIGS. 3a, 3b show the inner fabric layer 1.2 with the first intermediate layer 1.3 arranged above it and the second intermediate layer 1.4 enlarged. The second intermediate layer 1.4 adjoins the first intermediate layer 1.3 or the spacer layer at the top. While the fabric layer 1.2 and the second intermediate layer 1.4 are formed from a textile material, the spacer layer 1.3 has a rod or hair structure. These rods or hair are formed as pile threads. According to the embodiment example in FIG. 3a, the hair or sticks 1.3a are arranged at an angle to each other. This angle is an acute angle of about 40. According to the embodiment example in FIG. 3b, the sticks or hair 1.3a are aligned parallel to each other and at the same time normal to the neighbouring fabric layer 1.2 or intermediate layer 1.4. The spacer layer 1.3 is mechanically connected to both the fabric layer 1.2 and the second intermediate layer 1.4, for example by weaving. The spacer layer 1.3 can also be regarded as a composite layer together with the second intermediate layer 1.4. Likewise, the spacer layer 1.3 together with the fabric layer 1.2 and the second intermediate layer 1.4 can be regarded as a composite layer. This is because the spacer layer 1.3 is not stable on its own because, by definition, it is only formed from hair arranged next to each other.

[0033] As shown in principle in FIG. 3b, the spacer layer 1.3 has a volume V, which is composed of the volume S of the sticks 1.3a located therein and the remaining air volume L. The ratio S/L of air volume L to volume S is approximately 0.01 to 0.1.

[0034] As shown in FIGS. 3a, 3b, the fabric layer 1.2 has the outer surface 1.2a. In addition, the fabric layer 1.2 has a cooling medium 2, such as paraffin, which is integrated into the fabric layer 1.2.

[0035] According to embodiment example FIG. 3c, the damping layer 1.1 is provided adjacent to the second intermediate layer 1.4.

[0036] The same is also intended for the embodiment example FIG. 3a. The architecture of the first intermediate layer 1.3 or the rod or hair structure is independent of the first or second intermediate layer 1.3, 1.4.

[0037] FIG. 4 shows a capsule or chamber 2.1 with a coolant 2.2 contained therein, which is a pcm material. The chamber 2.1 itself does not change its aggregate state. It serves as a reservoir and is mechanically connected to the fabric of the fabric layer 1.2 for integration into the inner fabric layer 1.2.
