CA 2189347

A single-piece strong, flexible back support (62) for use in seats such as automobile seats or office chairs, includes a central body portion (72) with outwardly extending support fingers (80) such that an arch having a variable apex is formed when the back support is subtended longitudinally. The longitudinal location of an apex and the shape of the arch formed on the back support changes responsively to a load imposed by a person's back. The inventive back support is capable of taking a variety of shapes thereby providing maximum comfort and support regardless of the user's spinal curvature or posture and position relative to the back support.

L'invention traite d'un support dorsal (62) monobloc, souple et résistant. Ce support est conçu pour être utilisé dans les sièges d'automobiles ou pour des chaises de bureaux. Il comprend une partie de corps centrale (72) dotée de doigts de support s'étendant vers l'extérieur (80), de telle sorte qu'un arc a le sommet variable soit formé lorsque le support est sous-tendu dans le sens longitudinal. L'emplacement longitudinal d'un sommet et la forme de l'arc formé sur le support dorsal varient en réponse à la charge imposée par le dos d'un individu. Le support dorsal selon l'invention peut adopter plusieurs formes, et assure ainsi un confort et un support maximal quelle que soit la courbure de la colonne vertébrale, ou la posture et la position de l'individu par rapport au support dorsal.
