Eriksen conjured the winner as Hull paid in full for Gaston Ramirez's reckless red card.
Harry Kane's 10th goal of the season levelled things just after the hour when Eriksen's free-kick came back off the post and the Dane completed a 2-1 success with a clinical finish in the dying moments.
"That gave us a bit a confidence for our next games. In the second half we played very well," Eriksen told Sky Sports 1.
"In the first half we started slow and they were quicker than we were.
"In the second half we played well, forward and attacking, and of course we played well against 10 men and it gave us more space."
