Leverkusen, Germany -- Lantal, a Swiss supplier serving the aviation industry, has developed a seating system that uses films made of thermoplastic polyurethane (TPU) from Covestro.
Air travellers can individually adjust the firmness of their seats or backrests by further inflating the cushions or releasing air from them, Covestro said.
The innovation was used in the Solar Impulse 2 (Si2), a plane which circumnavigated the globe using only sun power. Si2 also features Covestro's insulation and other products supplied by Covestro, as UTECH-polyurethane.com has reported in the past.
Covestro added that the seats are in 170 aircraft already.
Installing Lantal’s seating, said Covestro, saves of up to three kilos per seat in business class and five kilos in first class. In terms of comfort, the elastic and flexible TPU films ensure that the pressure inside the cushions is optimally distributed, added Covestro.
Andreas Guhmann, technology director for pneumatic comfort systems at Lantal, said the reduced weight “saves fuel and reduces CO2 emissions”.
The system’s "zero maintenance requirement" helps to further reduce operating costs, added Guhmann.
