Rucksack

Abstract

The present invention relates to a backpack that has a reinforcement ( 1 ) arranged, at least in the central portion ( 11 ), in the half-thickness (Ep) which includes the front surface ( 101 ). The front surface ( 101 ) is positioned opposite the rear surface ( 100 ) which is adapted to be positioned on the user's back. The backpack also has a compression system ( 20 ) which, at least in the central portion ( 112 ), tends to press the rear surface ( 100 ) towards the reinforcement ( 1 ).

1 . Backpack having: 
 a rear surface ( 100 ) adapted to be positioned on the user's back    a front surface ( 101 ) positioned opposite the rear surface ( 100 ) characterized in that it has a reinforcement ( 2 ) which is arranged, at least in a central portion ( 112 ) in the half-thickness (Ep) of the backpack which includes the front surface ( 101 ), and in that it has a compression system ( 20 ) that, at least in the central portion ( 112 ), tends to press the rear surface ( 100 ) towards the reinforcement ( 1 ).    
     
     
         2 . Backpack according to  claim 1 , characterized in that the reinforcement ( 1 ) is positioned substantially on the front surface ( 101 ), and in that the reinforcement ( 1 ) extends upwardly and downwardly along at least three arms ( 11 ,  12 ,  13 ,  14 ) which are connected to the rear surface ( 100 ).  
     
     
         3 . Backpack according to  claim 1 , characterized in that the reinforcement ( 2 ) is made of a linear element.  
     
     
         4 . Backpack according to  claim 3 , characterized in that it has a compression system ( 120 ) arranged between the front surface  101  and the reinforcement  2 .  
     
     
         5 . Backpack having, 
 a rear surface ( 100 ) adapted to be positioned on the user's back,    a front surface ( 101 ) positioned opposite the rear surface ( 100 ), characterized in that it has a reinforcement ( 1 ) extending into an arch along a transverse plane of the backpack, at least on the front surface of the backpack.    
     
     
         6 . Backpack according to  claim 5  characterized in that the reinforcement extends from the rear surface substantially over all of the transverse periphery of the backpack.  
     
     
         7 . Backpack according to claims  5  or  6  characterized in that it has a compression system between the rear surface of the backpack and the reinforcement.  
     
     
         8 . Backpack according to claims  5  or  6  characterized in that the reinforcement can be folded for carrying.  
     
     
         9 . Backpack according to claims  5 - 8 , characterized in that the reinforcement extends only over the lower half of the backpack.
