- the adjusting spring elements 1030 which are suspended under pretension in the support plate 1090 cause a rotational movement of the lamellae recordings 1060A, 1060B to the bow rotation axis A ( Figure 7A), so that the bracket / paddle assembly 1070 according to the principles of the invention automatically a predeterminable front position in the backrest 14 occupies and a maximum buckling position of the backrest surface 14RF not shown is effected.
- FIG. 7A the stirrup / paddle arrangement 1070 moves forward, into the plane of the page, while according to FIG. 7B, the stirrup / paddle arrangement 1070 moves to the right out of the plane of the page.
- the lamellae and the 1040A, 1040B and lamellae 1060A, 1060B are displaced by the lamellar groove 1040C and the spring adjusting forces as well as by the limitations of the degrees of freedom the yoke / paddle arrangement 1070 in the backrest 14 limited relative to each other in the foremost position, the maximum camber, whereupon, by applying a return force directed counter to the forward position of the stirrup / paddle assembly 1070, the seated user spends the contour-adaptive element the paddles 1070B and the stirrup 1070A located behind them back into a desired position, in particular a desired camber position.
- Figure 7D shows the possibility of displacement of the lamellae 1060A, 1060B along the lamellar groove 1040C and by the arrows is shown in a schematic representation of how far the doubly arranged in the embodiment Paddels 1070B and bracket 1070A on the respective bow rotation axis A in the different curvature layers of a contour adaptive Move the backrest 14 of a vehicle seat.

Abstract
L'invention concerne un siège et en particulier un siège pour véhicule automobile qui présente un appui (10) de siège qui comprend une pièce d'assise (12) et un dossier (14) qui peut être déplacé par rapport à cette pièce d'assise, l'appui de siège (10) étant disposé à déplacement sur une structure porteuse (16) du siège avec adaptation du contour de la surface de dossier (14RF) pour pouvoir le déplacer. Selon l'invention, on prévoit que la structure porteuse (16) comprenne un bâti de base (18). Le bâti de base (18) présente un bâti de base (18B) situé du côté du dossier et dans lequel un élément (770, 870, 970, 1070) à contour adaptatif est disposé et peut être libéré par un mécanisme de verrouillage et de déverrouillage (720, 750/ 880/ 920, 950 /1020, 1050) d'un dispositif d'ajustement (700, 800, 900, 1000), grâce à quoi l'élément à contour adaptatif prend automatiquement une position avant prédéterminée et en particulier une position à courbure maximale, suite à quoi, pour l'adaptation du contour aux parties du corps du passager tournées vers l'assise, un déplacement dans la position souhaitée peut être établi en appliquant une force de rappel orientée dans la direction opposée à la position avant et l'élément (770, 870, 970, 1070) à contour adaptatif peut être à nouveau verrouillé dans la position souhaitée et en particulier dans une position où il présente la courbure souhaitée.
