Abstract

Le problème décrit par la présente invention est de fournir un coussin de siège qui permet d'améliorer la sensation en position assise. La solution selon l'invention porte sur des capteurs d'occupation de siège 4 qui se présentent sous la forme d'un film fixé à la surface d'une pièce rapportée 3. La pièce rapportée 3 est pourvue de sections de découpe 30b qui sont formées à la périphérie des capteurs d'occupation de siège 4 et sont configurées sous la forme de trous traversants s'étendant dans la direction de l'épaisseur de la pièce rapportée 3. Les sections de découpe 30b facilitent donc la déformation de la pièce rapportée 3 située à la périphérie des capteurs d'occupation de siège 4. Ceci permet de réduire la force de réaction de la pièce rapportée 3 appliquée au bord des capteurs d'occupation de siège 4 lorsque la charge d'un occupant du siège a été appliquée sur les capteurs d'occupation de siège 4. Il est donc possible d'empêcher une telle déformation telle que la déformation vers le haut du bord des capteurs d'occupation de siège 4 (la forme de la surface des capteurs d'occupation de siège 4 est plus facile à maintenir). Ainsi, il est possible d'éviter que le bord des capteurs d'occupation de siège 4 ne rende l'occupant du siège inconfortable et d'améliorer ainsi la sensation en position assise.
