Protective Helmet

Abstract

A protective helmet with a helmet shell ( 3 ) which, when it is in use, at least partly encloses the user's head with the exception of the face area, a chin guard ( 1 ) which, when it is in use, encloses the lower parts of the user's face area, as well as a visor ( 4 ) preferably arranged in a pivoting manner on the helmet shell ( 3 ) for covering the visual field opening between helmet shell ( 3 ) and chin guard ( 1 ), with the chin guard ( 1 ) comprising two sections ( 1 a , 1 b ) which are movable relative to each other. It is provided in accordance with the invention that each of the two chin guard sections ( 1 a , 1 b ) is pivotally arranged on the helmet shell ( 3 ), and said pivoting arrangement of the chin guard sections ( 1 a , 1 b ) on the helmet shell ( 3 ) takes place every time by means of a flexible plate element ( 2 ) which connects the helmet shell ( 3 ) to the corresponding chin guard section ( 1 a , 1 b ).

       3 . A protective helmet according to  claim 1 , wherein the two chin guard sections ( 1   a ,  1   b ) each have a chin protection surface ( 6 ) in their lower section which protrudes laterally in the direction towards the interior of the helmet. 
   
   
       4 . A protective helmet according to  claim 1 , wherein the chin guard sections ( 1   a ,  1   b ) each comprise a fastening area ( 7 ) at their end facing the helmet shell ( 3 ) and a closing area ( 13 ) with a closing surface ( 8 ) at their end averted from the helmet shell ( 3 ), with the two closing surfaces ( 8 ) being spaced from one another in an opening position of the two chin guard sections ( 1   a ,  1   b ) and rest against each other in a closing position which can be reached by pivoting the two chin guard sections ( 1   a ,  1   b ) 
   
   
       5 . A protective helmet according to  claim 4 , wherein a closing mechanism ( 11 ,  14 ) is arranged in the area of the closing surfaces ( 8 ) which spatially fixes the two chin guard sections ( 1   a ,  1   b ) against each other in their closing position. 
   
   
       6 . A protective helmet according to  claim 4 , wherein one of the closing surfaces ( 8 ) comprises a groove ( 9 ) and the other closing surface ( 8 ) comprises a spring ( 15 ) associated with the groove ( 9 ), with groove ( 9 ) and spring ( 15 ) engaging into each other in the closing position. 
   
   
       7 . A protective helmet according to  claim 1 , wherein the two chin guard sections ( 1   a ,  1   b ) are pretensioned in their opening position. 
   
   
       8 . A protective helmet according to  claim 4 , wherein the fastening area ( 7 ) of the two chin guard sections ( 1   a ,  1   b ) each terminates in a lateral surface ( 16 ) facing the helmet shell ( 3 ), which lateral surface rests on one support surface ( 17 ) of the helmet shell ( 3 ) in the closing position of the chin guard section ( 1   a ,  1   b ) and is spaced from the support surface ( 17 ) in the opening position of the chin guard sections ( 1   a ,  1   b ). 
   
   
       9 . A protective helmet according to  claim 8 , wherein the lateral surface ( 16 ) of the fastening area ( 7 ) of the chin guard sections ( 1   a ,  1   b ) and the support surface ( 17 ) of the helmet shell ( 3 ) are each arranged in a stepped manner, with the stepped sections engaging into each other in the closing position of the chin guard sections ( 1   a ,  1   b ).
