Helmet providing position feedback

Abstract

A system for optimizing a rider's head position during riding, said system comprising, a headwear comprising, a sensor unit enabling determining in real time a value corresponding to the inclination I 1 of the riders head in the plane defined by direction X and the field of gravity. A processing unit configured to compare the I 1 value in real-time in real time with a reference value I REF . An output unit, providing an (realtime) output signal to the rider in function of the comparison performed by the processing unit.

         11 . A system for optimizing a rider's head position during riding, said system comprising:
 a headwear comprising:
 a sensor unit enabling determining in real time a value corresponding to the inclination I 1  of the riders head in the plane defined by direction X and the field of gravity; 
 a processing unit configured to compare the I 1  value in real-time in real time with a reference value I REF ; 
 an output unit, providing an (realtime) output signal to the rider in function of the comparison performed by the processing unit. 
   
     
     
         12 . The system according to  claim 11 , wherein said headwear is a helmet; glasses or an earpiece to we worn by the rider. 
     
     
         13 . The system according to  claim 11 , said system comprising:
 a helmet comprising:
 an outer casing designed to have a direction X 1  wherein said helmet has a drag (coefficient) lower than the drag (coefficient) of said helmet in any other direction; 
 a sensor unit integrated in the helmet enabling determining a value corresponding to the angle between the direction X 1  and a predetermined direction X REF  defined in the plane defined by the field of gravity and the direction X 1 ; 
   an output unit, providing an output signal to the helmet wearer in function of the value determined by the sensor unit.   
     
     
         14 . The system according to  claim 13 , wherein said helmet is a cycling helmet; skiing helmet or snow-board helmet, or equestrian or motorcycle helmet. 
     
     
         15 . The system according to  claim 13 , wherein said helmet is a time trial cycling helmet, triathlon helmet or road cycling helmet. 
     
     
         16 . The system according to  claim 11 , comprising a sensor determining the inclination of the surface whereon the rider rides in the direction of the movement. 
     
     
         17 . The system according to  claim 11 , comprising at least three sensors, one integrated in the helmet, on to be provided on the rider, separate from the helmet and one to be provided on the vehicle of the rider, allowing determining the relative position of the rider and it's helmet in view of the vehicle. 
     
     
         18 . The system according to  claim 11 , comprising at least one sensor allowing determining the wind direction in view of the helmets position. 
     
     
         19 . The system according to  claim 13 , the helmet comprising a signal emitter for emitting an output signal to the output unit. 
     
     
         20 . The system according to  claim 13 , comprising an element of weight movably mounted in a tail of the helmet and an actuation and guiding means allowing moving the weight in said tail in view of the output of the sensor unit.
