Abstract
The invention relates to a seat back for a vehicle with a one-piece supporting structure made of light metal alloy, with a frame having an essentially rectangular contour and defining the upper, the lower and the two lateral delimitations of the seat back. A particularly stable embodiment is achieved by having a cross-shaped reinforcement rib accommodated in the frame in the vicinity of its diagonals, said rib being provided with rib structures arranged thereon in a grid-like configuration.
