ABSTRACT:
A seat-back frame for automotive vehicles comprising a rectangular frame of a rigid material, the frame having two upper and two lower corners, a seat belt connected to one upper corner and a tensile member obliquely extending between an upper and a diagonally lower corner of the frame to reinforce it against rhombic deformation due to external force applied in a lateral direction of the frame due to load applied to the frame, the tensile member being flexed or bowed to some extent in the rearward direction of the seat-back frame to avoid any interference with a cushioning material and cushioning springs when they are pushed backward by an occupant leaning on the seat-back and being flexible enough to straighten under tensile load.
