Capacitive occupant sensor
First Claim
1. A capacitive occupant sensor comprising an electrostatic sensor mat arranged inside of a vehicle seat and detecting existence or kind of an occupant seated on the vehicle seat based on a capacitance variation of the electrostatic sensor mat, whereinthe mat includes a plurality of U-shaped U-parts arranged in a first direction and a second direction approximately perpendicular to each other,each of the U-parts has an opening defined by a part of the mat recessed in the first direction or the second direction,the U-parts located adjacent to each other are connected with each other in the second direction so as to define a S-shaped S-part, in a manner that the openings alternately open toward a first side of the first direction or a second side of the first direction,the S-part is one of a plurality of S-parts,the S-parts located adjacent to each other are combined with each other in the first direction, in a manner that the opening open toward the first side and the opening open toward the second side oppose to each other in the first direction, andthe mat has a meandering structure defined by the plurality of S-parts.

Abstract
A capacitive occupant sensor includes a sensor mat having U-parts arranged in a first direction and, a second direction perpendicular to each other. The U-parts located adjacent to each other are connected in the second direction so as to define S-parts, in a manner that openings of the U-parts alternately open toward a first side of the first direction or a second side of the first direction. The S-parts located adjacent to each other are combined in the first direction, in a manner that the opening open toward the first side and the opening open toward the second side oppose to each other in the first direction. The mat has a meandering structure defined by the S-parts.
