Abstract:
1. Vehicle seat for equipment with shoulder belts connected to a seat backrest ( 21 ) wherein an energy absorbing device ( 1 ), acting on the seat backrest, comprises deformable energy absorbing means ( 12 ), with at least one arcuate area ( 13 , 14 ) of plastically fragmentable material, opposing the rotation of said seat backrest ( 21 ) with respect to a lower seat structure ( 20 ), in one direction, corresponding to a forward-leaning movement of said seat backrest, a first part ( 2 ), connected to the lower seat structure ( 21 ), respectively to the lower portion of the seat backrest ( 20 ), being rotably interconnected, via said deformable energy absorbing means ( 12 ), with a second part ( 4 ), connected to the lower portion of the seat backrest ( 20 ), respectively to the lower seat structure ( 21 ), whereas releasable retention means ( 16 ) are provided between said first part ( 2 ) and said second part ( 4 ), allowing the rotation of said first part with respect to said second part into the direction opposite to said one direction, corresponding to a backward-leaning direction of the seat backrest, without acting on said energy absorbing means, whereas the rotation of said first part with respect to said second part into said one direction is subjected to the reaction of said energy absorbing means.
