Abstract

La présente invention comprend : un module de capteur (10) ayant une unité d'alimentation électrique (12), un ensemble capteur (11), et une unité de câblage (13) servant à connecter l'unité d'alimentation (12) à l'ensemble capteur (11) ; et un siège (20) ayant une plaque inférieure (21) destinée à l'installation du module de capteur (10) sur une surface interne d'un pneu. L'unité d'alimentation électrique (12), l'ensemble capteur (11), et l'unité de câblage (13) sont disposés dans un plan parallèle à une surface de plaque de la plaque inférieure (21) du siège (20). Des surfaces latérales (13A, 13B) de l'unité de câblage (13) sont pourvues de parties évidées de telle sorte que, lorsqu'elles sont vues à partir d'une direction verticale, la largeur entre ces dernières diminue avec la distance à l'écart de l'unité d'alimentation électrique (12) et de l'ensemble capteur (11), et la largeur est plus étroite au niveau d'une partie centrale verticale qu'au niveau de parties d'extrémité verticales. Une paire d'éléments de retenue (22A, 22B) qui s'adaptent dans les parties évidées est érigée sur la plaque inférieure (21) du siège (20).
