Abstract

L’invention concerne un système d’estimation (1) de la taille d’un usager d’un siège (10). Le système d’estimation (1) comprend : le siège (10) comprenant une assise (12) et un dossier (11) ; au moins un premier capteur de pression (21) agencé dans le dossier (11) à une première hauteur vis-à-vis de l’assise (12), la première hauteur étant adaptée pour que le premier capteur de pression (11) soit soumis à l’appui du dos de l’usager uniquement lorsque ce dernier présente une taille supérieure à une première taille prédéfinie ; une unité de traitement (40) configurée pour déterminer une valeur d’estimation de la taille de l’usager sur la base d’une première valeur pression fournie par le premier capteur de pression (11). L’invention concerne en outre un procédé de fabrication et un procédé d’estimation de la taille d’un usager d’un siège. Figure pour l’abrégé : figure 1The invention relates to a system (1) for estimating the height of a seat user (10). The estimation system (1) comprises: the seat (10) including a seat (12) and a backrest (11); at least one first pressure sensor (21) arranged in the backrest (11) at a first height relative to the seat (12), the first height being adapted so that the first pressure sensor (11) is subjected to the pressure of the user's back only when the user is taller than a first predefined height; a processing unit (40) configured to determine an estimated value of the user's height based on a first pressure value provided by the first pressure sensor (11). The invention further relates to a method for manufacturing and a method for estimating the height of a seat user. Figure for the abstract: Figure 1
