Abstract
The invention relates to a seatback frame for a vehicle seat, comprising a lower structure provided with two side uprights, and an upper structure provided with a horizontal torsion bar surmounted by an arch. The first end of the torsion bar is prevented from rotating relative to one of the two uprights of the lower structure and is secured to one end of the arch. The second end of the torsion bar is mounted to pivot freely relative to the other side upright of the lower structure, while being secured to the other end of the arch. A seat belt is mechanically connected to the arch of the upper structure, with said upper structure being dimensioned so as to deform plastically when the seat belt is subjected to a traction force.
