In one embodiment, a lower bracket is attached to a front cross member of the base frame for supporting the lower end of a power tilting mechanism. An upper bracket is attached to the front cross member of the seat frame for supporting the upper end of the power tilting mechanism for tilting the seat frame relative to the base frame. An electronic control module is mounted on the lower bracket underneath the seat.
