The core (1) of a seat back, which will be upholstered to form the complete back, is a moulded plastics sheet bowed forwardly and with attachment points (12) near top and bottom for securing to a rigid support. The sheet is constructed to be stiffer over its upper portion then over the lower and, when secured, to be able to ripple or alter its curvature between the attachment points. It may have wings (2) inclining forwardly at each side with closed end slots (3) between the wings (2) and the central zone (8) of the core. The wings can be divided into generally horizontal sections carried by integrally moulded transverse ribs (4) spanning the slots (3), the division between sections being by slots (13) or narrow membranes (6). The top of the core may also be divided into side-by-sections, the division being by slots (14) or narrow membranes (11).

L'invention concerne la partie centrale (1) d'un dossier de siège rembourrée afin de constituer la globalité du dossier. Cette partie centrale est une feuille en plastique moulée courbée vers l'avant et pourvue de points de fixation (12) à proximité des portions supérieure et inférieure de manière à se fixer sur un support rigide. On élabore cette feuille pour qu'elle soit plus dure sur sa portion supérieure que sur sa portion inférieure, de manière à pouvoir onduler ou modifier sa courbure entre les points de fixation, lorsqu'elle est fixée. Ladite feuille peut aussi comporter des ailettes (2) qui s'inclinent vers l'avant au niveau de chaque côté et qui présentent des fentes d'extrémités fermées (3) entre les ailettes (2) et la zone centrale (8) de la partie centrale. Les ailettes sont généralement divisées en sections horizontales soutenues par des nervures transversales intégralement moulées (4) recouvrant les fentes (3), la séparation entre les sections étant assurée par des fentes (13) et des membranes étroites (6). La portion supérieure de la partie centrale peut aussi être divisée en sections latérales au moyen de fentes (14) ou de membranes étroites (11).
