         5 . Neck strap according to  claim 4 , wherein the curved portion is concave. 
     
     
         6 . Neck strap according to  claim 4 , wherein the two opposing major side edges include a curved portion and wherein the neck strap has at least partially a reduced width between the two opposing major side edges in the curved portion. 
     
     
         7 . Neck strap according to  claim 3 , wherein the main body comprises two opposing minor side edges, wherein the opposing major side edges interconnect the opposing minor side edges. 
     
     
         8 . Neck strap according to  claim 7 , wherein the first lower connection portion and/or the first upper connection portion is/are located at a first of the two opposing minor side edges, and/or wherein the second lower connection portion and/or the second upper connection portion is/are located at a second of the two opposing minor side edges. 
     
     
         9 . Neck strap according to  claim 8 , wherein the first and/or second lower connection portion extends substantially parallel to an adjacent portion of the respective minor side edge, and/or wherein the first and/or second upper connection portion extends substantially parallel to an adjacent portion of the respective minor side edge. 
     
     
         10 . Neck strap according to  claim 8 , wherein the first and/or second lower connection portion and/or respective portions of the minor side edges is/are oriented substantially perpendicular to a main axis of extension of the respective first and/or second lower mask connection strap. 
     
     
         11 . Neck strap according to  claim 8 , wherein the first and second upper connection portions and/or the adjacent portions of the minor side edges are oriented in an acute angle to a main axis of extension of the respective first and second lateral crown straps. 
     
     
         12 . Neck strap according to  claim 8 , wherein respective first and second transitional edge portions are connected tangentially with the respective portions of the minor side edges adjacent to the respective first and second upper connection portions. 
     
     
         13 . Neck strap according to  claim 8 , wherein respective first and second transitional edge portions intersects with the respective portions of the minor side edges adjacent to the respective first and second lower connection portions in an angle between about 60° to 120°. 
     
     
         14 . Neck strap according to  claim 13 , wherein the angle is between about 75° to 105°. 
     
     
         15 . Neck strap according to  claim 13 , wherein the angle is about 90°. 
     
     
         16 . Neck strap according to  claim 1 , wherein the neck strap is symmetrical to a first axis, wherein the first axis in an application position is substantially parallel to the sagittal plane of a user. 
     
     
         17 . Neck strap according to  claim 16 , wherein the neck strap includes a second axis that extends perpendicular to the first axis. 
     
     
         18 . Neck strap according to  claim 17 , wherein a width perpendicular to the second axis of the neck strap is lowest between a curved portion of two opposing major side edges of the main body. 
     
     
         19 . Neck strap according to  claim 17 , wherein a width perpendicular to the second axis of the neck strap is highest at a cross-section in which a major side edge intersects with a minor side edge. 
     
     
         20 . Neck strap according to  claim 7 , wherein the major side edges and/or the minor side edges are rounded.
