He told The Gazette: “In terms of an intimidating atmosphere, there's no better place than Loftus Road. It's been said many times before, but it's true.
“It's not just me saying it. Other players will tell you when QPR are on the front foot and the Loft is rocking, no-one wants to be the away side.
“We've got to have that for these last nine games because they're so, so important.
“One thing that really hit home at Hull was how united they are. The crowd got them through that game and we need to have the same at our place.
“My message to the fans is that they're entitled to voice their opinion, either at games or by staying away. They have to do what they think is right.
“But what we all want is what's best for Queens Park Rangers, and I'd ask the fans to put aside any grievances for those nine games.”
Saturday's defeat at Hull leaves Rangers in real danger of dropping into League One.
They will face Southampton tomorrow without the injured Bignot and suspended Lee Cook, while a vital match against fellow strugglers Barnsley looms.
Bignot added: “If there are people who didn't think we were in a real relegation battle, then they certainly know differently now.
“If there were one or two in that dressing room thinking ‘we'll be okay', then it's been a wake-up call.
“But there are some senior pros here who know the score. We're aware of the situation but we're positive – we've got nine cup finals at home and we can stay up.
“All of us – players and fans – have to ask ourselves what we can do at this time for the good of QPR. And in terms of the fans, it certainly isn't staying away.
“I know it's expensive and some people might be unhappy for various reasons, but we really need them.
“And it's no good players being upset about being picked one week and then not being picked.
“My attitude now, as captain, is no different to when I was on the transfer list and out of the side earlier in the season.
“It's not about me or any individual – it's about this club. Everybody's priority now has got to be to keep Queens Park Rangers in the Championship.
“No-one is going to want to come and play us at a Loftus Road that's rocking. And from our point of view, it's the same as in any walk of life – you perform better when you're being encouraged.
“QPR fans will never let you down. I know that from the time I've been here. So hopefully we can all now come together and do what we need to do to stay up.”
