Abstract

A modular helmet system comprises a helmet and a chin bar detachably mountable to the helmet. The helmet comprises two receiving-brackets. The chin bar may be inserted into the receiving-brackets of the helmet with its two ends in front in a substantially straight line, wherein the chin bar is lockable in the receiving-brackets in an end position. Each of the two receiving-brackets comprises two insertion flanks which extend towards each other along the direction of insertion at an acute centering angle, wherein the insertion flanks are configured to center the chin bar in the vertical direction when being inserted and to form a stop for the chin bar in the end position of the chin bar.

First claim

What is claimed is:

1. A modular helmet system comprising a helmet and a chin bar detachably mountable to the helmet,
wherein the helmet comprises two receiving-brackets,
wherein the chin bar is insertable into the receiving-brackets of the helmet with two ends of the chin bar along an insertion direction in a substantially straight line, wherein the chin bar is lockable in the receiving-brackets in an end position,
wherein each of the two receiving-brackets comprises two insertion flanks which extend towards each other along the insertion direction at an acute centering angle, wherein the insertion flanks are configured to center the chin bar between the insertion flanks when being inserted and to form a stop for the chin bar in the end position of the chin bar;
wherein the helmet system comprises a locking device for locking the chin bar in the end position to the helmet, wherein the locking device comprises at least one locking opening at each of the two receiving-brackets of the helmet, wherein the locking device comprises at least one movable latch at each of the two ends of the chin bar which is configured to engage in the at least one locking opening of the respective receiving-bracket in a locking position, and wherein the locking device comprises at least one handle at the chin bar, through actuation of the at least one handle the at least one latch is moved out of the locking position into an unlocking position.

2. The modular helmet system according to claim 1 ,
wherein the insertion flanks of the respective receiving-bracket are formed as rectilinear, at least in sections.

3. The modular helmet system according to claim 1 ,
wherein the centering angle has a value in a range from 30 degrees to 60 degrees.

4. The modular helmet system according to claim 1 ,
wherein the chin bar comprises a respective insertion wedge at each of its two ends, wherein the respective insertion wedge comprises two abutment flanks which are configured, at least in sections, to be complementary to the insertion flanks of the respective receiving-bracket of the helmet, wherein the abutment flanks lie in a form-fit manner against the insertion flanks of the respective receiving-bracket in the end position of the chin bar.

5. The modular helmet system according to claim 4 ,
wherein each of the two insertion wedges comprises an insertion section having a trapezoidal contour.

6. The modular helmet system according to claim 4 ,
wherein each of the two receiving-brackets comprises a support groove at at least one of the two insertion flanks, wherein each of the two insertion wedges comprises a respective support rib at at least one of the two abutment flanks which projects in a vertical direction from the respective abutment flank, and wherein the respective support rib engages in the support groove of the respective receiving-bracket in the end position of the chin bar.

7. The modular helmet system according to claim 4 , wherein the at least one locking opening of the respective receiving-bracket is formed at one of the two insertion flanks of the respective receiving-bracket, and wherein the at least one latch projects out of one of the two abutment flanks of the respective insertion wedge in the locking position and engages in the at least one locking opening of the respective receiving-bracket.

8. The modular helmet system according to claim 7 ,
wherein the at least one locking opening comprises two locking openings formed at each of the two insertion flanks of the respective receiving-bracket, wherein the at least one moveable latch comprises two movable latches at each of the two ends of the chin bar, wherein each of the two latches of the respective end of the chin bar projects from a respective one of the two abutment flanks of the respective insertion wedge and engages in a respective one of the two locking openings of the respective receiving-bracket in the locking position.

9. The modular helmet system according to claim 8 , wherein the at least one handle is a common handle, the two latches of the respective end of the chin bar are biased towards their locking position, wherein the two ends of the chin bar are associated with the common handle and a deflecting device, wherein the deflecting device converts an actuating movement of the common handle into a respective unlocking movement of the two latches, whereby the unlocking movements of the two latches take place in different directions.

10. The modular helmet system according to claim 9 , wherein the two latches, the deflecting device and the common handle of the two ends of the chin bar form a locking assembly, wherein the locking assemblies of the two ends of the chin bar are configured identical.

11. The modular helmet system according to claim 1 ,
wherein a magnetic element is arranged at the respective receiving-bracket and a magnetic counter-element is arranged at the respective end of the chin bar, wherein the magnetic element and the magnetic counter-element exert a magnetic force of attraction on the chin bar when the chin bar is being inserted into the receiving-brackets, in order to support an insertion movement and to secure the chin bar in its end position.

12. The modular helmet system according to claim 1 ,
wherein the helmet system further comprises two ear protection modules which are configured to be selectively inserted into the two receiving-brackets of the helmet instead of the chin bar, wherein each of the two ear protection modules comprises an insertion wedge, wherein the respective insertion wedge comprises two abutment flanks which are configured, at least in sections, to be complementary to the insertion flanks of the respective receiving-bracket, wherein the abutment flanks of the ear protection modules are lie in a form-fitting manner against the insertion flanks of the respective receiving-bracket in an end position of the respective ear protection module.

13. The modular helmet system according to claim 1 ,
wherein a magnetic element is arranged at the respective receiving-bracket and a magnetic counter-element is arranged at the respective end of the chin bar, wherein the magnetic element and the magnetic counter-element exert a magnetic force of attraction on the chin bar when the chin bar is being inserted into the receiving-brackets, in order to support an insertion movement and to secure the chin bar in its end position;
wherein the helmet system further comprises two ear protection modules which are configured to be selectively inserted into the two receiving-brackets of the helmet instead of the chin bar, wherein each of the two ear protection modules comprises an insertion wedge, wherein the respective insertion wedge comprises two abutment flanks which are configured, at least in sections, to be complementary to the insertion flanks of the respective receiving-bracket, wherein the abutment flanks of the ear protection modules lie in a form-fitting manner against the insertion flanks of the respective receiving-bracket in an end position of the respective ear protection module; and
wherein the two ear protection modules do not have a mechanical locking device, wherein each of the two ear protection modules comprises a magnetic counter-element, wherein the magnetic element of the respective receiving-bracket and the magnetic counter-element of the respective ear protection module are configured to exert a magnetic force of attraction on the ear protection module when the respective ear protection module is being inserted, in order to support an insertion movement and to secure the respective ear protection module in its end position.
