Abstract

A safety helmet (100) includes a helmet shell (7), with a bearing support structure (2, 5, 9, 21), with a helmet-side coupling point and with a module adapter (1). The bearing support structure (2, 5, 9, 21) is fastened to the helmet shell (7) on an inside. A helmet-side adapter coupling point of the module adapter (1) can be connected detachably to the safety helmet-side adapter coupling point of the module adapter (1). The module adapter (1) holds a module at the safety helmet (100). A process for fastening a module detachably to a safety helmet (100).

First claim

What is claimed is:

1. A safety helmet comprising:
an arched helmet shell;
a bearing support structure fastened on an inside to the helmet shell;
a helmet-side coupling point forming a part of the bearing support structure or of the helmet shell and located within an area enclosed by the helmet shell;
a module adapter comprising a helmet-side adapter coupling point and a module-side adapter coupling point; and
an additional module adapter comprising an additional adapter helmet-side adapter coupling point and an additional adapter module-side adapter coupling point, wherein:
the helmet-side adapter coupling point is connected or detachably connectable to the helmet-side coupling point;
the module-side adapter coupling point is configured to be detachably connected to a module;
the module adapter is configured to hold the module at the safety helmet with the module connected to the module-side adapter coupling point and the helmet shell-side adapter coupling point connected to the helmet-side coupling point;
the helmet-side coupling point is configured to selectively be connectable to the helmet-side adapter coupling point of the module adapter and to the additional adapter helmet-side adapter coupling point of the additional module adapter; and
the module-side adapter coupling point of the module adapter differs from the additional adapter module-side adapter coupling point of the additional module adapter based on geometry thereof or at least one dimension thereof or based on geometry thereof and at least one dimension thereof.

2. The safety helmet in accordance with claim 1 , further comprising an additional helmet-side coupling point, wherein:
the additional helmet-side coupling point forms a part of the bearing support structure or of the arched helmet shell;
the additional helmet-side coupling point is located within the area enclosed by the arched helmet shell; and
the helmet-side coupling point and the additional helmet-side coupling point are configured such that a head of a user of the safety helmet is located between the helmet-side coupling point and the additional helmet-side coupling point.

3. The safety helmet in accordance with claim 1 , wherein:
the module adapter has a predetermined breaking point; and
the predetermined breaking point is located between the helmet-side adapter coupling point and the module-side adapter coupling point.

4. The safety helmet in accordance with claim 3 , wherein a segment of the module adapter that is located between the predetermined breaking point and the helmet shell-side adapter coupling point is arranged entirely within the area enclosed by the arched helmet shell.

5. The safety helmet in accordance with claim 1 , wherein:
the helmet-side adapter coupling point of the module adapter comprises a U-shaped fastening element;
the helmet-side coupling point comprises an opening and a web adjoining the opening; and
the U-shaped fastening element is configured to be passed through the opening and be moved after passing through the opening into a position in which the U-shaped fastening element encompasses the web from two sides.

6. The safety helmet in accordance with claim 5 , wherein:
the U-shaped fastening element has two first openings and the web has an additional opening; and
a screw is passed or is passable through both the first openings and the additional opening.

7. The safety helmet in accordance with claim 1 , wherein the module adapter is located entirely within the area enclosed by the arched helmet shell.

8. The safety helmet in accordance with claim 1 , wherein the module adapter extends in a plane and has a spacer at right angles or in an oblique position relative to the plane.

9. The safety helmet in accordance with claim 1 , wherein:
the detachable connection between the helmet-side adapter coupling point and the helmet-side coupling point is establishable by a linear displacement of the module adapter in a direction of the helmet-side coupling point; or
the detachable connection between the module-side adapter coupling point and a module is establishable by a linear displacement of the module in the direction of the module-side adapter coupling point; or
the detachable connection between the helmet-side adapter coupling point and the helmet-side coupling point is establishable by a linear displacement of the module adapter in a direction of the helmet-side coupling point and the detachable connection between the module-side adapter coupling point and a module is establishable by a linear displacement of the module in the direction of the module-side adapter coupling point.

10. The safety helmet in accordance with claim 1 , wherein:
the bearing support structure comprises a bearing ring and a holding ring;
the bearing ring is configured so as to encompass a head of a user of the safety helmet;
the holding ring is connected to the arched helmet shell and to the bearing ring;
the holding ring is located at least partially between the bearing ring and the arched helmet shell; and
the helmet-side coupling point forms a part of the holding ring such that the module adapter is connected or detachably connectable to the holding ring.

11. An arrangement comprising:
a module; and
a safety helmet comprising: an arched helmet shell; a bearing support structure fastened to the helmet shell; a helmet-side coupling point forming a part of the bearing support structure or of the arched helmet shell and located within an area enclosed by the helmet shell;
a module adapter comprising a helmet-side adapter coupling point and a module-side adapter coupling point, and
an additional module adapter comprising an additional adapter helmet-side adapter coupling point and an additional adapter module-side adapter coupling point, wherein:
the helmet-side adapter coupling point is detachably connected or connectable to the helmet-side coupling point;
the module-side adapter coupling point is detachably connected or connected to the module;
the module adapter holds or is configured to hold the module at the safety helmet with the module detachably connected or connectable to the module-side adapter coupling point and the helmet shell-side adapter coupling point detachably connected or connectable to the helmet-side coupling point, wherein the module is detachably connected to connectable to the module adapter of the safety helmet; the helmet-side coupling point is configured to selectively be connectable to the helmet-side adapter coupling point of the module adapter and to the additional adapter helmet-side adapter coupling point of the additional module adapter; and
