An apparatus is provided for detecting a position of a body on a support surface (38) of a bed (10). The apparatus includes at least one first sensor (70) coupled to the bed (10) and at least one second sensor (104) located adjacent the support surface (38). The at least one first sensor (70) has an output signal which is variable in response to changes in a weight applied to the support surface (38). The at least one second sensor (104) has an output signal which is variable in response to changes in the position of the body on the support surface (38). The apparatus also includes a controller (50) having inputs configured to receive the output signals from the first and second sensors (70, 104). The controller (50) is configured to monitor the output signals, to provide an indication of changes in the position of the body relative to the support surface (38), and to provide an indication if the body exits the support surface (38).

L'invention concerne un appareil servant à détecter la position d'un corps sur la surface de support (38) d'un lit (10). L'appareil comporte au moins un premier capteur (70) relié au lit (10) et au moins un deuxième capteur (104) situé de façon adjacente à la surface de support (38). Le(s) premier(s) capteur(s) (70) produi(sen)t un signal de sortie variant en fonction de changements de poids sur la surface de support (38). Le(s) deuxième(s) capteur(s) (104) produi(sen)t un signal de sortie variant en fonction de changements de position du corps sur la surface de support (38). L'appareil comporte également un organe de commande (50) comportant des entrées conçues pour recevoir les signaux de sortie provenant des premier(s) et deuxième(s) capteurs (70, 104). L'organe de commande (50) est conçu pour surveiller les signaux de sortie, indiquer des changements de position du corps par rapport à la surface de support (38), et indiquer si le corps n'est plus en contact avec la surface de support (38).
