Abstract
The invention relates to improvements to devices for attaching seat backs on corresponding sitting portions. To assemble a vehicle seat back on a corresponding sitting portion, the seat back comprises two trapezoidal flat cases (1), each containing a bent wire spring (8) whose ends (8.sub.1) are urged towards each other, these ends passing through two horizontal slots formed in the cases. The sitting portion comprises two trapezoidal wedges (2) complementary to the cases. The oblique edges of the wedges are formed with inclined slots (12, 13) through which the ends of the spring also pass.
