3. A seat according to claim 1 , wherein after a pivoting of said receiving box ( 7 ) out of said starting position ( 23 ) by approximately 90°, said receiving box ( 7 ) is adapted to be rotated about the axis of rotation ( 16 ) that extends perpendicular to said hinge ( 13 ) and approximately through a center thereof.

4. A seat according to claim 3 , wherein said axis of rotation ( 16 ) that extends through said hinge ( 13 ) is connected therewith.

5. A seat according to claim 3 , wherein said receiving box ( 7 ), in a position rotated relative to said starting position ( 23 ) by 180° about said axis of rotation ( 16 ), is adapted to be pivoted in a direction toward said seat base ( 2 ) and into a position where said receiving box is again disposed on said seat base.

6. A seat according to claim 1 , wherein back side ( 21 ) is opposite said cushioned side.

7. A seat according to claim 6 , wherein at least one of said seat base ( 2 ) and said receiving box ( 7 ) is provided with means for bracing to ensure that said receiving box ( 7 ) can be stepped upon.
