Title
(EN) LOAD DETECTION SENSOR UNIT
(FR) UNITÉ DE CAPTEUR DE DÉTECTION DE CHARGE
(JA) 荷重検知センサユニット
Abstract
(EN) This load detection sensor unit (SU) comprises: a load detection sensor (70) that has a switch (SW) including a first electrode (71) and a metal plate (72); a substrate (5) that has a mounting surface 5S on which the load detection sensor (70) is mounted; an upper case (4) having an upper surface (47S) and a first pusher (43) that receive a pressing force from a seat cushion (SC); a pressing member (90) that has an upper surface (91s) pressed by the first pusher (43) and a second pusher (92) for pressing the metal plate (72) by means of the pressing force received by the upper surface (91S); a lower case (3) that restricts the movement of the upper case (4); and a lid member (80) that restricts the movement of the pressing member (90). The lower case (3) can change the angle of the upper surface (47S) with respect to the mounting surface 5S and sets, to a predetermined amount, a movable amount of the upper case (4) in a direction parallel to the mounting surface (5S), and the lid member (80) reduces, to the predetermined amount or less, a movable amount of the pressing member (90) in the direction parallel to the mounting surface (5S).
(FR) Cette unité de capteur de détection de charge (SU) comprend : un capteur de détection de charge (70) qui présente un commutateur (SW) comportant une première électrode (71) et une plaque métallique (72) ; un substrat (5) qui présente une surface de montage (5S) sur laquelle le capteur de détection de charge (70) est monté ; un boîtier supérieur (4) présentant une surface supérieure (47S) et un premier poussoir (43) qui reçoit une force de pression à partir d'un coussin de siège (SC) ; un élément de pression (90) qui présente une surface supérieure (91s) pressée par le premier poussoir (43) et un second poussoir (92) permettant de presser la plaque métallique (72) au moyen de la force de pression reçue par la surface supérieure (91S) ; un boîtier inférieur (3) qui limite le mouvement du boîtier supérieur (4) ; et un élément de couvercle (80) qui limite le mouvement de l'élément de pression (90). Le boîtier inférieur (3) peut modifier l'angle de la surface supérieure (47S) par rapport à la surface de montage (5S) et définit, à une quantité prédéterminée, une quantité mobile du boîtier supérieur (4) dans une direction parallèle à la surface de montage (5S), et l'élément de couvercle (80) réduit, à la quantité prédéterminée ou à une quantité inférieure, une quantité mobile de l'élément de pression (90) dans la direction parallèle à la surface de montage (5S).
(JA) 荷重検知センサユニット(SU)は、第1電極(71)と金属板(72)とで構成されるスイッチ(SW)を有する荷重検知センサ(70)、荷重検知センサ(70)が載置される載置面5Sを有する基板(5)、シートクッション(SC)からの押圧力を受ける上面(47S)及び第1押し子(43)を有する上部ケース(4)、第1押し子(43)に押圧される上面(91S)及び上面(91S)が受ける押圧力によって金属板(72)を押圧する第2押し子(92)を有する押圧部材(90)、上部ケース(4)の移動を規制する下部ケース(3)、及び押圧部材(90)の移動を規制する蓋部材(80)を備える。下部ケース(3)は、載置面5Sに対する上面(47S)の角度を変化可能にするとともに載置面(5S)と平行な方向における上部ケース(4)の移動可能量を所定量にし、蓋部材(80)は、載置面(5S)と平行な方向における押圧部材(90)の移動可能量をこの所定量より少なくする。
