Rollable mat for allowing vehicles to pass, the mat having distinct pockets

Abstract

The invention relates to a mat ( 10 ) suitable for being rolled up and having a longitudinal direction (L) and a transverse direction (T), the mat having at least first and second pockets ( 20; 20′ ) extending in the transverse direction of the mat, each of the first and second pockets being defined between at least a first portion ( 22, 22′ ) and a second portion ( 28, 28′ ) fastened to the first portion. The invention is characterized by the fact that the first portion of each pocket presents a free lateral end edge ( 26, 24′ ) placed facing the other pocket and extending in the transverse direction of the mat, the free lateral end edge ( 26 ) of the first portion ( 22 ) of the first pocket ( 20 ) being spaced apart from and distinct from the free lateral end edge ( 24′ ) of the first portion ( 22′ ) of the second pocket ( 20′ ).

         5 . The mat according to  claim 4 , wherein the piece comprises a textile ply. 
     
     
         6 . The mat according to  claim 4 , wherein the piece includes a first face covered in a layer of polymer. 
     
     
         7 . The mat according to  claim 1 , wherein the second portion of each pocket presents a free lateral end edge placed facing the other pocket and extending in the transverse direction of the mat, and wherein the free lateral end edge of the second portion of the first pocket is spaced apart from and distinct from the free lateral end edge of the second portion of the second pocket. 
     
     
         8 . The mat according to  claim 7 , wherein each of the first and second portions of the first pocket includes a first face covered in a layer of polymer, the free lateral end edges of the first and second portions being fastened together. 
     
     
         9 . The mat according to  claim 7 , wherein it includes a junction element connecting the first pocket to the second pocket, said junction element being fastened to the free lateral end edges of the first portions of the first and second pockets. 
     
     
         10 . The mat according to  claim 9 , wherein the junction element comprises a textile ply. 
     
     
         11 . The mat according to  claim 9 , wherein the junction element includes at least one perforation. 
     
     
         12 . The mat according to  claim 9 , wherein the junction element has a first face covered in a layer of polymer. 
     
     
         13 . The mat according to  claim 9 , wherein the junction element presents an end margin sandwiched between the first and second portions of the first pocket. 
     
     
         14 . The mat according to  claim 9 , wherein each of the first and second portions of the first pocket includes a first face covered in a layer of polymer, the junction element and the first and second portions of the first pocket being vulcanized together. 
     
     
         15 . The mat according to  claim 1 , wherein it includes a first face covered in a layer of polymer. 
     
     
         16 . The mat according to  claim 1 , wherein the first portion of the first pocket extends over all or part of the width of the mat. 
     
     
         17 . The mat according to  claim 1 , wherein the first portion of the first pocket is made up of a plurality of sheath elements that are spaced apart from one another. 
     
     
         18 . The mat according to  claim 1 , wherein the distance considered in the longitudinal direction of the mat between the first and second pockets is longer than the width of the first portion of the first pocket.
