Patent NO-317307-B1 (NO)
Inventor: HALSNES ODD
IPC: A42B3/22
Filed: 2002-10-31
Abstract: The present invention relates to a helmet and a basic helmet concept with highly flexible construction of use in a number of different situations. The helmet can provide varying degrees of protection and can very easily alternate between the various forms of protection. In addition the individual parts of the helmet can easily be replaced. The helmet consists of an outer helmet with a head-protecting part ( 1 ) which essentially covers the side, top and back of the head, a chin guard ( 39 in front of the lower part of the face and a transparent visor ( 2 ) which covers the field of vision of the person using the helmet, together with an inner helmet which is connected to the outer helmet and which inner helmet abuts against the user's head. The helmet is characterised in that the two elements-chin guard ( 3 ) and visor ( 2 ) are pivotably connected concentrically about a point (D) on each side of the head-protecting part, with the result that the visor ( 2 ) moves within the inside of the head-protecting part ( 1 ) of the helmet and the chin-protecting part ( 3 ) of the helmet moves within the visor ( 2 ).
