Crash Helmet

Abstract

The invention relates to a crash helmet comprising a shock resistant helmet shell ( 1 ) provided with a visor opening ( 3 ) recoverable with a visor ( 12 ), at least one actuating element ( 7, 7 ′) which is mounted on the external surface of the shell ( 1 ), a functional element ( 4, 16 ) of the helmet adjustable by an actuating element ( 7, T) and the actuating element ( 7, T) connected to the functional element ( 4, 16 ) by a transmission device ( 9, 9 ′). The aim of the invention is to improve the operability of the actuating element ( 7, T) by placing the actuating element ( 7, 7 ′) on the protective helmet ( 1 ) side in the area of the lower edge thereof.

       6 . The crash helmet as claimed in  claim 4 , characterized in that the slide ( 8 ,  8 ′) is designed so that it can be operated from the lower side of the helmet.  
   
   
       7 . The crash helmet as claimed in  claim 6 , characterized in that the slide ( 8 ′) is provided with a sliding button which can be actuated from the lower side of the helmet.  
   
   
       8 . The crash helmet as claimed in  claim 1 , characterized in that the actuating element ( 7 ,  7 ′) is a twist knob.  
   
   
       9 . The crash helmet as claimed in  claim 1 , characterized in that the transmission device ( 9 ,  9 ′) is designed to provide direct mechanical transmission of the movement of the actuating element ( 7 ,  7 ′).  
   
   
       10 . The crash helmet as claimed in  claim 9 , characterized in that the transmission device ( 9 ,  9 ′) comprises at least one Bowden cable ( 10 ,  10 ′).  
   
   
       11 . The crash helmet as claimed in  claim 1 , characterized in that the functional element ( 4 ,  16 ) connected to the actuating element ( 7 ,  7 ′) is arranged on the inner side of the helmet shell ( 1 ) outside of the chin part ( 2 ).  
   
   
       12 . The crash helmet as claimed in  claim 11 , characterized in that the functional element ( 4 ,  16 ) is mounted above a peripheral region of the helmet shell ( 1 ) that forms a continuation of the chin part ( 2 ).  
   
   
       13 . The crash helmet as claimed in  claim 12 , characterized in that the functional element ( 4 ,  16 ) is a sunshield ( 4 ) which is guided on the inner side of the helmet shell ( 1 ) and can be moved into the region of the visor opening ( 3 ).  
   
   
       14 . The crash helmet as claimed in  claim 13 , characterized in that the transmission device ( 9 ) leading from the actuating element ( 7 ) is connected by two lateral ends ( 5 ) of the sunshield ( 4 ).  
   
   
       15 . The crash helmet as claimed in  claim 14 , characterized in that the lateral ends ( 5 ) of the sunshield ( 4 ) are mounted in guides ( 6 ) which form a curved section.  
   
   
       16 . The crash helmet as claimed in  claim 15 , characterized in that the curved section has a pivot point which is arranged at a distance from the corresponding lateral end ( 5 ) of the sunshield ( 4 ).  
   
   
       17 . The crash helmet as claimed in  claim 1 , characterized by a ventilation slide ( 16 ), as the functional element, which can be used to close off or uncover at least one ventilation opening ( 17 ) in the forehead region and/or upper head region of the helmet shell ( 1 ).
