Spurs' rocky first season under Mauricio Pochettino appeared to be heading for another low ebb at the KC Stadium on Sunday when they went in at half-time 1-0 behind.
A team showing six changes - largely injury-enforced - were turning in a thoroughly disjointed performance when Tigers forward Gaston Ramirez was dismissed for kicking out at Jan Vertonghen.
The tone of the match flipped in an instant, with playmaker Eriksen at the heart of the visitors' revival.
Harry Kane levelled matters after the Denmark international whipped a free-kick against the woodwork and Eriksen earned a 2-1 success in the 90th minute when he found the bottom corner.
The turnaround nudged Tottenham into 10th place in the Barclays Premier League standings, but better is still needed at home, where Pochettino's men have lost four times in six attempts.
"We can take a lot of good things and a lot of confidence with us from this game," said Eriksen, whose side host Partizan Belgrade in the Europa League on Thursday and Everton on Sunday.
"Every game is different and we still have to work hard and improve a lot of things.
"Of course we know they (home fans) expect more and we do as well.
"We always want to win when we play at home and if we don't they are not happy - it's normal.
"It's nothing to do with that
We just need to play better at home.
"We need to improve, because we have some good games and bad games
When we become more stable, we will have a good season."
That Eriksen was on the pitch to secure the late triumph over the Tigers was significant for the 22-year-old.
He had started all 12 of Spurs' league matches this season, but has been substituted in half of those - including being hooked at half-time against Stoke and Aston Villa earlier this month.
He was, then, pleased to have the chance to settle matters this time.
"I think it's something I wanted to show
The last two games I was pulled out after 45 minutes," he said.
"Every player wants to play more than 45 minutes, but it's the decision of the coach.
"You have to work hard
I had the chance this time and I showed that 90 minutes is good for me."
Former Tottenham captain Michael Dawson, who made the move to East Yorkshire in the summer, was crushed to be on the losing side against his old team-mates.
"Everybody knows what it meant to me to play in this game, and to lose in the way we did was a massive disappointment - especially after the first half," he said.
"The red card changed the game
It was going to be one-way traffic from there because Tottenham have some top players.
"Christian Eriksen's free-kick is something I used to see on a daily basis and then his finish in the last minute was top class.
"But at the end of the day we've come away with no points, so it is massively disappointing."
