Protecting helmet with raising/lowering mechanism of the visor

Abstract

A protecting helmet is disclosed having a rigid outer shell, a front opening in the rigid shell for the face of a user, a protective visor rotatable between a lowered position intercepting the front opening and a raised position disengaged from the front opening, and a raising/lowering mechanism of the protective visor. The raising/lowering mechanism has a base member, movably or integrally constrained to, or made in a single piece with, the outer shell and arranged in a side position with respect to the front opening and a fastening pin constrained in a respective opening of the protective visor. The base member has a seat adapted to rotatably and reversibly house the fastening pin and an elastic countering member for the fastening pin. The base member has an unlocking device configured to act on the elastic countering member to release the fastening pin from the seat.

1 . A helmet comprising a rigid outer shell, a front opening in said rigid shell for the face of a user, a protective visor rotatable between a lowered position intercepting, at least partially, the front opening and a raised position disengaged from said front opening, and a raising/lowering mechanism to raise/lower the protective visor, the raising/lowering mechanism comprising:
 a) a base member, movably or integrally constrained to, or made in a single piece with, the outer shell, and arranged in a side position with respect to said front opening;   b) a fastening pin constrained in a respective opening of the protective visor;   wherein said base member comprises a seat adapted to rotatably and reversibly house said fastening pin;   wherein said seat of said base member comprises an elastic countering member for said fastening pin; and   wherein said base member comprises an unlocking device configured to operate on the elastic countering member to release the fastening pin from the seat.   
     
     
         2 . The helmet according to  claim 1 , wherein said base member comprises a body and a lid constrained to said body. 
     
     
         3 . The helmet according to  claim 1 , wherein said unlocking device is translationally movable in said base member. 
     
     
         4 . The helmet according to  claim 1 , wherein said unlocking device comprises a portion, optionally being a protuberance, adapted to move and/or deform said an elastic countering member. 
     
     
         5 . The helmet according to  claim 1 , wherein said elastic countering member comprises a body coupled to a spring. 
     
     
         6 . The helmet according to  claim 1 , wherein said elastic countering member comprises inclined tilted surface (S 1 ) adapted to cooperate with said fastening pin, so that a translation movement of the fastening pin closer to said elastic countering member causes a movement and/or deformation of said elastic countering member to allow the fastening pin to be inserted into the seat. 
     
     
         7 . The helmet according to  claim 1 , wherein said elastic countering member has a coupling surface (S 2 ) adapted to cooperate with said fastening pin, so that when the fastening pin is inserted into the seat, a translation movement of the fastening pin away from said seat is hampered, and is optionally substantially prevented, by the cooperation between said fastening pin and said coupling surface (S 2 ). 
     
     
         8 . The helmet according to  claim 1 , wherein said unlocking device comprises a protrusion adapted to cooperate with said fastening pin so as to axially move said fastening pin to move said visor away from the seat of the mechanism. 
     
     
         9 . The helmet according to  claim 1 , wherein said base member comprises a toothed portion adapted to cooperate with one or more protuberances of said visor. 
     
     
         10 . The helmet according to  claim 1 , wherein said base member comprises a housing portion made in said outer shell or integrally constrained to said outer shell, wherein said body is constrained, optionally in a rotatable way, to said housing portion. 
     
     
         11 . The helmet according to  claim 1 , wherein said mechanism comprises at least a first and a second magnetic-coupling member, said first magnetic-coupling member being constrained to, or made in a single piece with, said fastening pin, said second magnetic-coupling member being constrained to, or made in a single piece with, said base member.
