Abstract: A capacitive sensor apparatus (12) is disposed between the bottom cushion (18) and frame (16) of a seat (10). The sensor apparatus (12) includes first and second mutually parallel rigid force translation plates (22, 24) biased apart by a set of springs (26), first and second conductor plates (28, 30) centrally affixed to inboard faces of the first and second force translation plates (22, 24), and a control circuit (32) responsive to the gap capacitance between the first and second conductor plates (28, 30). The force translation plates (22, 24) are joined in a manner to maintain the conductor plates (28, 30) parallel to each other while permitting movement of either force translation plate relative to the other in a mutually perpendicular direction.
