Safety helmet

Abstract

Disclosed is a safety helmet including an energy distribution part arranged in a body part of the safety helmet for distributing the energy of an impact in the safety helmet.

Claims

1. A safety helmet comprising: a body part with a crown area and sides located below the crown area, the body part including an energy distribution part formed on an inside of the body part, the energy distribution part being defined by a wall thickness change of the body part so that at least a part of a thickness of the energy distribution part is more than a thickness of the body part to transfer force from a top of the body part, through the energy distribution part, to the sides of the body part, the energy distribution part distributing energy of an impact in the safety helmet, the body part and the energy distribution part being formed of a same material.

2. The safety helmet according to claim 1, wherein the energy distribution part has a shape of a cross.

3. The safety helmet according to claim 2, wherein at least part of the energy distribution part is arranged to the crown area of the safety helmet.

4. The safety helmet according to claim 2, further comprising a suspension system.

5. The safety helmet according to claim 1, wherein at least part of the energy distribution part is arranged to the crown area of the safety helmet.

6. The safety helmet according to claim 1, further comprising a suspension system.

7. The safety helmet according to claim 1, wherein the safety helmet is made of polycarbonates (PC), polycarbonate glass fiber, polyamide, high-density polyethylene (HDPE), low density polyethylene or polyoxymethylene (POM).

8. The safety helmet of claim 1, further comprising a suspension system, wherein at least part of the energy distribution part is arranged inside the suspension system on the inside of the crown area of the body part, wherein a shape of the energy distribution part inside the crown area is a cross shape, and wherein the wall thickness of the energy distribution part changes relative to the body part with edges of the energy distribution part tapering down from a top of the crown area to deflect and transfer force from the crown area, through the energy distribution part, to the sides of the helmet.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(7) Referring to FIGS. 1-5, the safety helmet 100 comprises a body part 102 and an energy distribution part 104.

(8) The energy distribution part 104 is arranged to the body part 102 of the safety helmet 100 for distributing the energy of an impact in the safety helmet 100. The energy distribution part 104 is arranged to the inside of the safety helmet to the crown area 106.

(9) The energy distribution part 104 has the shape of a cross 108. The shape may be formed by a wall thickness change 110 relative to the body part 102. The wall thickness change 110 may be an embossed feature such as a protrusion form. The edges of the energy distribution part 104 may taper down in order to transit smoothly the energy of an impact.

(10) At least a part of the wall thickness of the energy distribution part 104 is more than the wall thickness of the body part 102. The body part 102 may have a wall thickness of approximately 1.5-2 mm in the crown area. The energy distribution part 104 may have a wall thickness of approximately 3-10 mm.

(11) The energy distribution part 104 is arranged inside the suspension system 112 of the safety helmet 100.

(12) The crown area 106 may be 110 mm or 120 mm, for example.

(13) The safety helmet 100 may be made of acrylonitrile butadiene styrene (ABS), polycarbonates (PC), polycarbonate glass fibre, polyamide (e.g. Nylon 6), high-density polyethylene (HDPE), low density polyethylene or polyoxymethylene (POM), for example.

(14) Consequently, a skilled person may, on the basis of this disclosure and general knowledge, apply the provided teachings in order to implement the scope of the present invention as defined by the appended claims in each particular case of use with the necessary modifications, deletions and additions.
