Document Type and Number:
Japanese Patent JP4666917
Kind Code:
B2
Abstract:
The presence sensor (1) is designed to detect the presence of a user at the level of an interface equipment (7), in particular that of the door handle of an automobile vehicle. The sensor (1) is of capacitive type and comprises a control module (2), a measuring electrode (3) and a reference electrode (4), designed for electromagnetic coupling. At least one of the electrodes (3,4) is in the form of a flexible metallic wire so to allow a direct positioning at the level of the interface equipment (7) whatever its profile. The metallic wire is in an electrical insulator sheathing. The handle comprises a gripping part which is mobile with respect to the door and designed so to be actuated by the user, and a fixed part (7b) positioned on the door; at least one of the electrodes (3,4) of the sensor (1) is laid out on the fixed part (7b). The handle also comprises the means for maintaining and guiding (8) the metallic wires forming the electrodes (3,4), in the form of grooves with insulator sheathing which are implemented by molding in the manufacturing of handle. The control module (2) comprises electronic components (2a) and printed circuit board (2b), and is positioned on the fixed part (7b) of the handle.
