ABSTRACT:
A vehicle seat, comprising an upholstered seat surface and an upholstered backrest, whereby the backrest may be folded forward about a first horizontal pivoting axis. A backrest element is integrated close to the front side of the upholstered backrest, which may be pivoted in the backrest about a second horizontal pivoting axis, which, in side view, is higher than the first horizontal pivoting axis. The backrest element is curved in the region of the second horizontal pivoting axis, such that an upper backrest piece is formed above the second horizontal pivoting axis and a lower backrest piece is formed below the second horizontal pivoting axis, which are inclined towards each other in the direction of the front side of the backrest. A mid upper area of the upper backrest piece lying in the lateral direction of the backrest and a mid lower area of the lower backrest piece lying in the lateral direction of the backrest, have a greater elasticity than the rest of the backrest element, or both said areas may be arched backwards.
