Abstract

The invention relates to an impact core for insertion inside an outer shell of a helmet. The impact core comprises a shock-proof material and is substantially dome-shaped having cut outs to increase the flexibility of the impact core. The cut out makes the impact core deformable and as a result the impact core can be adjusted according to different head shapes and sizes. The impact core comprises a substantially star-shaped cut out at a top and a plurality of elongated edge cut outs near an edge of said impact core. Further, each of a plurality of arms of said star-shaped cut out extends downward between two neighboring edge cut outs at the edge.

Description

Safety helmet with flexible impact core
FIELD OF THE INVENTION
The invention relates to helmets and, more particularly, to safety 5 helmets having an impact core.
BACKGROUND OF THE INVENTION
Typically, a safety helmet provides a user or a wearer protection from head injury or damage in case of an accident. There is a wide variety of 10 safety helmets available in the market. Various examples of safety helmets may include, but are not limited to, bicycle helmets, motor bike helmets, and racing car helmets.
Different users may have different head sizes. Generally, a shopkeeper measures the size of the users head with the help of a measuring 15 instrument, and accordingly provides a helmet from the variety of helmets present in the shop. The user selects a helmet after taking numerous fitting trials depending on the ease and comfort of its fit.
However, the disadvantage associated with the abovementioned methods for selecting the best fit safety helmet is that only the size of the 2 0 head is taking into.
Because apart from size, different users also have different head shapes, a helmet does not fit perfectly around the head. The user normally chooses a helmet that is comfortable but that does not fit perfectly. In fact, most often a helmet is chosen which is too spacious. This may lead to 25 unnecessary injuries when being involved in an accident.
In light of the foregoing, there is a need for a comfortable fit safety helmet according to various head sizes and shapes of different users.
OBJECT AND SUMMARY OF THE INVENTION
30 It is an object of the invention to provide a helmet that fits better on different heads as compared to the known helmets.
In a first aspect, the invention relates to a helmet which comprises an outer shell and an impact core arranged inside the outer shell. The impact 2 core comprises a shock proof material. The impact core is substantially dome-shaped and comprises at least one cut out. The at least one cut out increases the flexibility of the impact core. Further, the flexible impact core provides a deformable and an adjustable helmet for different head shapes.
5 In an embodiment, the at least one cut out starts at an edge of the impact core. In a particular embodiment, the impact core comprises a number of cut outs, each starting at an edge of the impact core. Multiple cut outs at the edge make the impact core flexible.
In an embodiment, the at least one cut out is arranged at top of the 10 impact core. The impact core comprises a substantially cross-shaped cut out at the top and a plurality of elongated cut outs near the edge of the impact core. Further, each of a plurality of arms of the cross-shaped cut out extends vertically downward between two neighboring cut outs at the edge. With the word downward US meant towards the edgeaf the impact core. The 15 combination of top cut outs alternating with the bottom cut outs results in a serpentine-shaped impact core. Accordingly, the serpentine-shaped impact core is deformable in different directions. Thus, the helmet deforms in different directions to adjust various head sizes and provides the best fit helmet to the user.
2 0 In an embodiment, the impact core comprises expanded polypropylene.
The expanded polypropylene is a multi-impact material and also flexible. The combination of the expanded polypropylene being flexible together with the cut out(s), results in a deformable impact core. Since expanded polypropylene is a multi-impact material, it increases the durability of the 25 helmet.
In an alternative embodiment, the impact core comprises expanded polystyrene. The expanded polystyrene is less flexible but also less costly than its other available variants.
In an embodiment, the impact core is produced using a moulding 30 technique. The moulding technique uses a single mold which considerably reduces the manufacturing time and makes the overall process simple.
In an embodiment, the outer shell of the helmet is made of acrylonitrile butadiene styrene (ABS). An outer shell of ABS material is impact resistant, 3 and when it is not excessively thick, is also slightly flexible, which makes it a preferred material for the outer shell. Further, in a preferred embodiment, the outer shell has a thickness in the range of about 0.5mm to about 3.5mm, and more preferably in the range of about 1.8mm to about 2.2mm. The 5 abovementioned thickness of the outer shell helps in achieving a deformity which results in expansion of the impact core to fit different head shapes. Additionally, it is easier to wear and remove the helmet with the abovementioned thickness of the outer shell. Instead of using ABS, alternative materials may be used for the outer shell, e.g. Polycarbonate.
10 In an embodiment, the helmet furthermore comprises a comfort core, and in a particular embodiment, the comfort core is substantially helmetshaped layer arranged at least partly inside the impact core. The comfort core is made of Ethylene vinyl acetate (EVA) rubber. Also, the comfort core comprises an upper portion and a lower portion. The upper portion is 15 substantially dome-shaped. The dome shape of the upper portion facilitates a base support to the impact core. Further, the lower portion surrounds a lower part of the skull of the user. In a particular embodiment, to provide a proper fit to the impact core when the comfort core is inserted in it, the upper portion of the comfort core is less thick than its lower portion.
2 0 The invention further relates to an impact core for use in a helmet as described above.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention and embodiments thereof will now be further elucidated 25 by means of figures, wherein:
Figure 1 schematically shows a representation of a helmet according to an embodiment of the present invention; and
Figures 2a, 2b, 2c, 2d, and 2e depicts a top-view, a side-view, a front-view, a first perspective view, and a second perspective view, respectively, of 30 the embodiment of Figure 1.
DESCRIPTION OF THE EMBODIMENTS
4
Figure 1 schematically shows a representation of a helmet 1 that comprises three layers - a comfort core 2, an impact core 3, and an outer shell 4. The arrangement of the three layers of the helmet 1 is in a manner such that, the comfort core 2 can be arranged at least partly inside the impact 5 core 3, and the impact core 3, along with the comfort core 2, can be arranged inside the outer shell 4.
In an embodiment, the comfort core 2 is made of foam or expanded rubber, such as Ethylene vinyl acetate (EVA) rubber. In the embodiment of Figure 1, the comfort core 2 is substantially a helmet-shaped layer and 10 comprises an upper portion 5 and a lower portion 6. The upper portion 5 is substantially dome-shaped which facilitates a base support to the impact core 3. Thus, the impact core 3 gets the base support from the comfort core 2, and both are closely fit into the outer shell 4 of the helmet 1. Further, the lower portion 6 surrounds a lower part of the skull of a 15 user. In a particular embodiment, the upper portion 5 is less thick than the lower portion 6 to properly accommodate the impact core 3.
Further, the outer shell 4 is preferably made of a shock-proof and a flexible thermoplastic, for example, acrylonitrile butadiene styrene (ABS). The flexible outer shell 4 easily accommodates the impact core 4 along with the 2 0 partly fit comfort core 2. Further, the impact core 3 deforms easily when the outer shell 4 is flexible. In a particular embodiment, the outer shell 4 has a thickness in the range of about 0.5mm to about 3.5mm, and more preferably in the range of about 1.8mm to about 2.2mm. The outer shell 4 is preferably made thin, so that the outer shell 4 is deformable to fit different head shapes 25 and sizes apart from being only strong. Additionally, the helmet 1 is easier to wear and remove from the head.
Furthermore, the second layer, i.e, the impact core 3 of the helmet 1 is substantially dome-shaped and comprises a shock-proof material. The shock-proof material in the impact core 3 makes the helmet 1 robust and 30 protects the user in case of accidents. In an embodiment, the impact core 3 comprises a number of cut outs, such as 7, 8, and 9. It should be noted that the three cut outs, i.e, 7, 8, and 9 have been depicted in Figure 1 only for exemplary purposes. However, the impact core 3 may have any number of 5 cut outs to provide proper fit to the different head shapes and sizes of the users. It may be apparent to any person skilled in the art that for simplification in the construction of the impact core 3, it may comprise only one cut out, such as the cut out 9.
5 Additionally, each of the cut outs 7, 8, and 9 starts from an edge of the impact core 3. It may be apparent to any person skilled in the art that the edge may be defined as the circumferential boundary of the surface of the substantially dome-shaped impact core 3. It may be also appreciated by a person skilled in the art that the cut outs 7, 8, and 9 provide sufficient space 10 for expansion of the impact core 3 to adjust according to the different head shapes of different users.
Figures 2a, 2b, 2c, 2d, and 2e depicts a top-view, a side-view, a front-view, a first perspective view, and a second perspective view, respectively, of the embodiment of Figure 1.
15 Figure 2a depicts the top view of the impact core 3 of Figure 1. In this embodiment, four cut outs 7, 10, 11, and 12 are arranged at top of the impact core 3. These cut outs 7, 10, 11, and 12 are slit-shaped and combine together to form a substantially cross-shaped cut out at the top of the impact core 3 and can alternatively be referred to as the arms of the cross shaped 2 0 cut out. Additionally, the impact core 3 comprises numerous other elongated cut outs 8,9,13, and 14 near the edge of the impact core 3 (as shown in Figure 2a). In this embodiment, the arms 7, 10, 11, and 12 of the crossshaped cut out extends vertically downward between two neighboring cut outs from the cut outs 8, 9, 13, and 14 at the edge. It should be noted that 25 these cut outs will be collectively referred as 7D14 in the subsequent paragraphs.
The cut outs 7-14 are of predefined length and width to provide maximum flexibility to the impact core 3. In the example of Figure 2a, the width of each of the slits 7-14 is about 10 mm. Furthermore, the pre-defined 30 angle of separation between two subsequent cut outs at the edge 13, 14 is about 75 degrees. Typical dimensions of the impact core 3 are shown in Figure 2a. It is noted that other dimension are possible. As will be appreciated by the skilled person, the cut-outs can be of varying shapes, and 6 the invention is by no means limited to the use of slit-shaped cut outs. It should however be noted that the cut-outs can not be too wide, since then, the protection of the head will be compromised.
Figures 2b, 2c, 2d, and 2e depict the side-view, the front-view, the first 5 perspective view, and the second perspective view, respectively, of the impact core 3. As shown in Figures 2b, 2c, 2d, and 2e, the arm 7 of the cross-shaped cut out extends vertically downward between two neighboring cut outs 8 and 9 at the edge. The combination of the top cut outs (or arms of the cross shaped cut out) 7, 10, 11, and 12 alternating with the bottom cut 10 outs 8, 9, 13, and 14 results in a serpentine-shaped impact core 3 which is deformable in different directions.
In a preferred embodiment, the impact core 3 comprises expanded polypropylene material (EPP). This material has advantageous properties, such as the material being multi-impact and flexible. The combination of the 15 expanded polypropylene material with the arrangement of the cut outs 7ml 4 results in a deformable impact core 3 which is highly durable.
In an embodiment, the density of the EPP material used for the impact core 3 lays between 20 and 100kg/m3, and preferably is about 60kg/m3. These densities showed good results during impact tests.
2 0 Alternatively, the impact core may comprise expanded polypro styrene (EPS) material or Polyurethane (PU).
The impact core 3 may be made using moulding technique. The moulding technique uses a single mold which considerably reduces the manufacturing time and makes the overall process simple.
25 Instead of using Ethylene vinyl acetate (EVA) rubber, the comfort core 5 may comprise relative low density EPP or EPS. A typical density for an EVA rubber comfort core could be about 30kg/m3.
Alternatively, the comfort core 5 could comprise textile, PU, rubber or Neoprene or a combination thereof. With Neoprene for example, several 30 sheets can be sewed together to form the comfort core.
It is emphasized that the present invention can be varied in many ways, of which the alternative embodiments as presented are just a few examples.
7 A person skilled in the art will readily appreciate that various features disclosed in the description may be modified and that various embodiments disclosed and/or claimed may be combined without departing from the scope of the invention. These different embodiments are, hence, non-limiting 5 examples. The scope of the present invention, however, is only limited by the subsequently following claims.
