Taking the load off aircraft seating with innovative hinge technology

26 April 2018
Founded in 1984, Italian-headquartered company Geven S.p.A. has evolved from its roots as a family-run business initially specialising in upholstery for the automotive sector to become one of the global leaders in the design and manufacture of aircraft seating and interiors. By achieving approved supplier status with top tier Aerospace OEMs Geven has demonstrated consistent reliability and outstanding quality, dedication and professionalism in the aviation sector.
 
Geven sought to replace their headrest hinge as part of their goal to reduce the overall weight of their seats, enabling airlines to meet industry environmental standards whilst at the same time maintaining a high level of user experience in an extremely competitive market.
 
THE CHALLENGE
New industry standards, as set by bodies such as the International Civil Aviation Organization (ICAO) and the EU emissions trading system (ETS), require airlines to reduce their fuel consumption and CO2 emissions. In response, Geven explored ways to reduce the weight of their aircraft seating without compromising function and passenger experience, or increasing production costs. When redesigning the head supports in their existing seating, they were looking for a solution that
would help to eliminate any avoidable weight or bulk. Geven’s seat headrests were previously fitted with heavy hinges that were more than 18mm in diameter. While these hinges functioned adequately, they added unnecessary weight to the seating and did not complement the design aesthetics.
 
Geven sought a product which would be light enough to help reduce the overall seat weight, but with a high enough level of functionality to meet the needs of the passengers of leading airlines. This posed a significant challenge because reducing the overall size, diameter thickness and weight of the hinge could potentially affect the performance of the headrest. In addition to these challenges, Geven was also looking for a product which would fit seamlessly within their complete range of aircraft seating.
 
THE SOLUTION
Geven replaced the existing headrest hinge with Southco’s E6 Constant Torque Position Control Hinge series, a low-profile high torque friction hinge measuring approximately 10mm in diameter. Southco’s E6 class hinge incorporates Southco’s patented Positioning Technology, which provides constant resistance throughout the entire range of motion, enabling airline passengers to easily position headrests and other mounted components with zero-drift and backlash, even under vibration or dynamic loads, holding them securely at any desired angle. In addition to helping reduce their headrest size, the E6 class hinge provided an added benefit in that it eliminated the need for secondary supports, simplifying Geven’s build process and reducing costs.
 
Based on a standard product, the overall cost of the development remained low. Southco slightly adapted the E6 hinge for Geven to add further length and provide greater torque, allowing them to design a headrest with low profile. Having been rigorously tested over 20,000 cycles with performance remaining within the optimal static torque range, the hinge ensures that the headrest maintains a consistent, high level of performance. As a result, using the E6 series has helped Geven to reduce the overall weight of their seats, helping airline companies to meet industry environmental standards while reinforcing quality, reliability and durability for their passengers.
 
THE IMPLEMENTATION
Integrating a proven solution like Southco’s E6 hinge series into Geven’s existing range of aircraft seating allows Geven to demonstrate exceptional value to their company and customers. As a standard product, the E6 is an affordable solution that offers design flexibility; furthermore, its long cycle life means that it is also helping airlines to reduce their maintenance costs. While the project started primarily as a retrofit initiative, the Southco hinge is now being built into both
premium and economy class seating ranges. Geven continues to experience the benefits of incorporating Southco technology; having won a range of additional contracts with leading worldwide airlines, they are reaching new clients with the prospect of supplying additional elements for their aircraft.
 
THE RESULTS
“Working with Southco, we were looking to upgrade our current headrest system as the former system was a bulky, visible solution that added extra weight without superior performance,” said Pasquale Rapullini, R&D Area Manager, Geven. “With new industry pressures, OEMs need suppliers to develop innovative solutions to help achieve challenging targets. The integration of the E6 into our new seat and headrest design was a major benefit to us, as we were able to cost-effectively reduce the profile of the hinge whilst maintaining high levels of torque. We are looking forward to continuing our partnership with Southco.”
