With airlines under pressure to slash fares and cram in ever more people without extending cabin space, passengers might soon be stacked on top of each other -- literally. This is our hellish version. Click on to see what real aviation engineers are coming up with.

Airbus has offered a chilling glimpse into what the future of air travel might hold with a patent that envisages two rows of seats layered on top of each other. The patent states that the design "still provides a high level of comfort for the passengers" with seats that could be reclined 180 degrees.

At least with the stacked-rows design passengers will actually be sitting down. Not so much with the so-called saddle seat, another Airbus patent, which would require them to assume a semi-squat position during a flight.

The seat (our imagined version shown here), which wouldn't look out of place on a bicycle, has no headrest, with back support also in limited supply. The patent admits that the increase in the number of seats is achieved to the detriment of the comfort of the passengers.

Fully-standing spaces were proposed by Ryanair boss Michael O'Leary a few years ago, although they haven't been rolled out. "We have no plans to trial or introduce standing flights," an airline spokesperson told CNN. If our rendition is even close to accurate, that's a good thing.

Zodiac Seat France's Economy Class Cabin Hexagon consists of a tightly packed jigsaw of alternating backward and forward seats, making it difficult to maintain the number one rule of traveling on any form of public transport -- avoiding eye contact. Or so we imagine here.

Not to be outdone, Boeing has filed its share of eccentric patents, such as the "upright sleep support system." Its purpose is to help passengers rest during a flight by letting them lean face-forward into a cushion that has a hole to accommodate eyes, nose and mouth.

Its purpose is to help passengers rest during a flight by letting them lean face-forward into a cushion. Another cushion supports the chest. Both are deployed from a backpack attached to the seat.

Rep. Steve Cohen, D-Tennessee, proposes establishing minimum dimensions for airline seats

Cohen says shrinking seats have become a safety issue

Airline industry says regulators have deemed seats safe

CNN  — 

Among things about which people are “mad as hell and not gonna take anymore,” shrinking airline seats have to be near the top of the list.

But now, a U.S. lawmaker isn’t just grumbling about being stuck in economy behind some inconsiderate lummox reclining his seat.

He’s doing something about it.

7 terrifying airline seat patents

Attempting something that’s never been done before, Rep. Steve Cohen, D-Tennessee, has proposed establishing mandatory federal minimum size standards for airline passenger seats.

“This issue, in my opinion is a microcosm of what the public is showing for Bernie Sanders and for Donald Trump,” Cohen told CNN on Wednesday. “It’s about an industry not being responsive to people and being responsive to special interests.”

We don’t need to tell you that airlines have put the squeeze on fliers over the years.

Dazzling new airline patent offers seats on top of aircraft

Narrower seats and seat pitches have helped airlines fit more seats on planes to allow overall lower fares and higher profit margins.

Just basic physics, right?

Cohen claims that seat width “has shrunk from 18 inches in the 1970s to about 16.5 inches today.”

Meanwhile, American bodies have widened.

In 1962, the U.S. government measured the width of the American backside in the seated position.

It averaged 14 inches for men and 14.4 inches for women.

A 2002 Air Force study showed male and female butts had blown up on average to more than 15 inches.

Then there’s seat “pitch” – the distance between any point on one seat to the same point on the seat in front.

Cohen says pitch has shrunk from “35 inches during the 1970s to about 31 inches today.”

Safety issue?

But Cohen isn’t selling his bill on comfort.

He’s selling it on safety.

He says that the Federal Aviation Administration (FAA) is putting passengers at risk because there hasn’t been adequate emergency evacuation testing of airline seating with rows set with pitch under 29 inches.

“Someday they will lose lives because of the size of the seats and somebody’s going to be sorry,” Cohen said.

Some consumer advocate groups have been calling on the industry to stop the squeezing, especially now that airlines are making big profits from low fuel prices.

But Brett Snyder of the consumer airline blog CrankyFlier isn’t so supportive.

“This is absurd,” Snyder said. “Without question, the FAA should ensure that passengers can quickly and safely get out of an airplane in an emergency, but that should be the only requirement on seat size and pitch.”

If passengers choose, they can pay for extra leg room, Snyder said.

“But by requiring minimum seat size and pitch, Congress would effectively be pushing the cost of plane tickets out of reach for the most price-sensitive travelers.”

Cohen is calling on the FAA to study seat safety regarding size and then, if necessary, issue minimum or specific seat sizes as a mandated federal industry standard.

Airline seats: Tricky positions

The powerful Washington airline lobbying group Airlines for America says the Department of Transportation’s Advisory Committee for Aviation Consumer Protection has decided to not make a recommendation on seat sizes.

The DOT oversees the FAA.

“We also believe that government should not regulate, but instead market forces, which reflect consumer decisions, and competition should determine what is offered,” Airlines for America told CNN in a statement Wednesday. “… And as with any commercial product or service, customers vote every day with their wallet.”

Cohen, a member of the House Transportation and Infrastructure Committee, plans to propose the legislation as an amendment to an FAA reauthorization bill on Thursday.

He’s also introduced it as a separate bill.
