Description

Technical Field

[0001] The invention relates to a head protection pad to be inserted into a helmet or a helmet cover. The head protection pad has a base body made of a pad material and a cover that at least partially surrounds the base body.

Background Art

[0002] Head protection pads to be inserted into helmets or helmet covers are already generally known. The head protection pad has a base body made of foam surrounded by a cover made of fabric (woven fabric). US2018 / 0242665A1 describes a fabric material such as a cover for a protective pad. The fabric material is covered by an outer layer consisting of a mixture of PCM, binder, and water. After drying, the outer layer is a mixture of PCM and binder. Alternatively, it is described that a cooling medium is integrated into the fabric carrier layer. US2006 / 0260026A1 describes a protective pad consisting of two protective layers. There is an inner first layer made of a low-performance material that is compressible (foldable) and impact-resistant, such as a knit spacer fabric with low resistance to fluid flow, as well as two fabric layers as the upper and lower layers. The inner first layer is sandwiched between the first fabric layer and the second fabric layer. All layers are surrounded by a cover layer applicable to the head.

[0003] The present invention is based on the problem of forming and arranging a head protection pad to be inserted into a helmet cover so that advantageous Cooling effects can be obtained.

Summary of the Invention

[0004] According to the present invention, this problem is solved in that the cover has , formed from a fabric material an outer layer and at least one inner layer, the outer layer is designed as a cooling layer and has a cooling medium integrated therein , and a spacer layer is provided that is disposed between the inner layer and the outer layer The cooling medium is a so-called pcm (phase change material). The PCM can absorb body temperature, thereby at least partially changing its aggregation state from solid to liquid. In this way, the temperature uniformity between the inner layer of the fabric and the scalp is ensured. As a result, it can be worn more comfortably. The outer layer designed as a cooling layer is in direct contact with the head and exhibits a corresponding cooling effect.

[0005] Also, it may be advantageous if the outer layer and / or the inner layer is formed from fabric. Each layer can preferably be designed as a fabric layer having a corresponding woven structure of the fabric fibers. Depending on the materials used, the fabric has advantageous physical properties. For example, the fabric has higher strength or higher resistance. The non-woven fabric material may have a lower density and thus be lighter in weight.

[0006] Also, it may be advantageous if paraffin is used as the cooling medium. Paraffin has stability and has a predetermined melting point of approximately 30°C. In the case of the fabric layer, the paraffin is integrated into or incorporated into the fabric layer. The paraffin can be integrated into the outer layer in the form of microcapsules. When heat is applied, the paraffin changes its state of aggregation from solid to liquid and absorbs excess heat from the head.

[0007] Also, it may be advantageous if a spacer layer is provided between the inner layer and the outer layer. The spacer layer ensures or supports the cooling effect of the cooling layer. The spacer layer has a thickness of 4.5 mm to 7 mm, or 5.5 mm to 6 mm. The cooling effect of the outer layer is improved by the spacer layer and the accompanying air cushion. Also, the drying of the outer layer and thus the absorption of sweat are improved.

[0008] Also, it may be advantageous if the spacer layer is directly adjacent to the outer layer. This reliably supports the cooling effect of the cooling layer.

[0009] In the present invention, it may be particularly important that the spacer layer is woven into the outer layer and / or the spacer layer is woven into the inner layer. This ensures a stable structure.

[0010] Regarding the design and arrangement according to the present invention, it may be advantageous if the spacer layer is formed from a number of sticks or hairs arranged parallel to each other or at an acute angle α to each other and aligned laterally with respect to the outer layer. 1 cm 2It may be advantageous if a surface density is provided such that there are 2,500 hits per stick, or between 2,000 and 10,000 hits per stick. Thereby, the back surface is ventilated while stability is ensured.

[0011] Also, it may be advantageous if the spacer layer has a thickness of at least 5 mm. The thickness is measured in the unloaded state.

[0012] The spacer layer is 200 g / m 2 or 150 g / m 2 to 300 g / m 2 and may be advantageous if it has a specific gravity.

[0013] The head protection pad is also used in bulletproof vests, heavy protective clothing, impact protection elements, motorcycle wear, and other impact protection headgear. Those of mild quality are also used as inner liners for leisure jackets, trousers, and gloves.

[0014] Also, it may be advantageous if the base body is formed from foam and / or gel. In the case of gel, the base body is designed as a gel cushion with an outer cover containing the gel. The cover can be joined to the foam or gel cushion.

[0015] Further advantages and details of the present invention are described in the claims and the specification and are shown in the drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0017] The head protection pad 1 shown in FIG. 1 has a cushion shape and has a cover 3. The head protection pad 1 formed in this way is attached to the inner surface 8.1 of the helmet or the helmet cover 8 as shown in FIG. 4 using holding means (not shown) such as adhesive tape or an adhesive.

[0018] According to FIG. 2a, the head protection pad 1 has an inner base body 2 made of a normal foaming material. The base body 2 is surrounded by the cover 3 on all sides.

[0019] According to FIG. 2b, the cover 3 has an outer layer 4 and an inner layer 5. The outer layer 4 contacts the head to be protected. Also, the outer layer 4 has a cooling medium 4.1. The cooling medium 4.1 is integrated into the outer layer 4 in the form of microcapsules. According to the following detailed view Z shown in FIGS. 3a and 3b, the cover 3 has a three-layer structure. The outer layer 4 also has an outer surface 4.2.

[0020] According to FIGS. 3a and 3b, the cover 3 has the above-mentioned outer layer 4 and inner layer 5, and a spacer layer 7 disposed between the outer layer 4 and the inner layer 5. The cover 3 has a thickness of approximately 3 to 5 mm and a specific gravity per unit area of 450 to 700 g / m 2 The outer layer 4 and the inner layer 5 are formed from a fabric material, while the spacer layer 7 has a rod structure or a hair structure. According to the example of FIG. 3a, the hair-like or stick 7.1 is arranged at an angle α with respect to each other. The angle α is an acute angle of about 40°. According to the embodiment example of FIG. 3b, the stick or hair-like 7.1 is aligned parallel to each other and at the same time perpendicular to the adjacent outer layer 4 or inner layer 5. The spacer layer 7 is mechanically connected to both the outer layer 4 and the inner layer 5, for example, by weaving.

[0021] As a rule, as shown in Fig. 3b, the spacer layer 7 has a volume V. The volume V consists of the volume S of the stick 7.1 arranged inside and the remaining air volume L. The ratio L / V of the air volume L to the total volume V is at least 0.9, or at least 0.95. There are 1,500 to 3,000 sticks 7.1 per square centimeter, providing a surface density. 2 A surface density is provided such that there are 1,500 to 3,000 sticks 7.1 per square centimeter.

[0022] As shown in Figs. 3a and 3b, the outer layer 4 has a gray outer surface 4.2. The outer layer 4 also has a cooling medium 4.1 integrated into the outer layer 4 in the form of microcapsules.

[0023] According to the embodiment of Fig. 4, a plurality of head protection pads 1 are attached to the inner surface 8.1 of the helmet 8 or the helmet cover via the connecting means such as Velcro fasteners. Thus, when the helmet 8 is worn, the head protection pads 1 can contact the head. The contact with the head occurs directly through the outer layer 4 provided with the cooling medium 4.1.
