Abstract
Abstract A spine support is provided in particular for the use in a seat of a vehicle with at least one bending element ( 20 ) and at least two independent operating elements ( 41 a , 42 a , 41 b , 42 b ) to bend the bending element ( 20 ), wherein the first operating element ( 41 a , 42 a ) engages a first part of the bending element ( 20 ) to cause first curvature of the spine support and the second bending element ( 41 b , 42 b ) engages a second part of the bending element ( 20 ) to cause a second curvature of the spine support so that the overall curved shape of the spine support is a superposition of the first and second curvature. According to a further aspect, the present invention relates to a spine support, in particular for the use in the seat of a vehicle with at least one bending element ( 20 ) and at least one supporting element ( 30 ′), wherein the at least one supporting element ( 30 ′) is flexibly attached to the at least one bending element ( 20 ).
