Abstract
A backrest for a seat includes an upper back portion having an integral, central extension, a lower back portion having a central cut-out, and hinges for pivotally connecting the upper and lower back portions together to permit free swinging movement of the extension through the cut-out about a pivot axis situated at a level above the extension so that substantially the entire extension can come out of the cut-out in a reclined position of the upper back portion to support the lower back of the seat occupant. The extension may be provided with a central recess separating two lateral prongs from one another, and an elastic band may then be used to span the recess between the prongs.
