Benefits of technology

The invention is a helmet and impact core that fits better on different heads compared to existing helmets and impact cores. The impact core is dome-shaped with cut outs that increase flexibility, including a star-shaped cut out at the top and elongated edge cut outs near the edge. The cut outs allow for a deformable and adjustable helmet for different head shapes. The flexible impact core makes the helmet fit better on different heads.

Problems solved by technology

However, the disadvantage associated with the abovementioned methods for selecting the best fit safety helmet is that only the size of the 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.
This may lead to unnecessary injuries when being involved in an accident.

Embodiment Construction

[0026]FIG. 1 schematically shows a representation of an embodiment of a helmet 1 according to an aspect of the invention. The helmet comprises three layers—a comfort core 2, an impact core 3 according to an aspect of the invention, 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 core 3, and the impact core 3, along with the comfort core 2, can be arranged inside the outer shell 4.

[0027]It is noted that the helmet may be a so called safety helmet.

[0028]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 FIG. 1, the comfort core 2 is substantially a helmet-shaped layer and 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 ...

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

FIELD OF THE INVENTION[0001]The invention relates to helmets and, more particularly, to impact cores and safety helmets having an impact core.BACKGROUND OF THE INVENTION[0002]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 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.[0003]Different users may have different head sizes. Generally, a shopkeeper measures the size of the user's head with the help of a measuring 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.[0004]However, the disadvantage associated with the abovementioned methods for selecting the best fit safety helmet is that only the size of the head is taking ...
