To save fuel costs, lightweight designs and materials are preferred for aircraft interiors. One of the challenges for aircraft seats is to reduce weight without compromising passenger comfort, or perhaps even while increasing comfort. This case study describes three different projects on lightweight designs for aircraft seats, using three-dimensional (3D) scanning methods (Franz, Kamp, Durt, Kilincsoy, Bubb, & Vink, 2011) to determine the ideal seat contour following the human body. The first project on upright sitting in an economy aircraft seat (Hiemstra-van Mastrigt, 2015) set out to collect imprints of the human body in a vacuum mattress by using a handheld 3D scanner to scan the body imprints and obtain a 3D surface. Subsequently, the different scans were superimposed in such a way that differences between the scans were minimized. Based on this “ideal curvature,” an adjustable seat pan concept was developed (Kuday, 2018). A similar 3D scanning method was applied in two other projects: first, developing a prototype for passengers sleeping sideways in a premium economy class aircraft seat (Lam et al., 2014) and, second, a human contour-based business class seating concept (Smulders et al., 2016). This case study concludes with advantages and recommendations for applying 3D scanning in similar projects.
Sitting still for extended periods of time can lead to physical discomfort and even serious health risks. Due to safety regulations, reducing passenger’ sitting time in aircrafts is not feasible. This paper presents the results of a laboratory study, in where an interactive airplane seat was compared with a current economy class seat. Participants used both seats for 3.5 h, and performed significantly more in-seat movements when using the interactive seating system. Furthermore, this interactive seat predominantly lead to significantly better comfort experiences and reduced discomfort experiences, however no significant differences have been found in self-reported localized musculoskeletal discomfort. Passengers indicated that they would prefer this interactive seat over a standard aircraft seat.
When experiencing comfort, the different human senses all play a role. According to Bubb (2008) [1], six factors determine discomfort: Smell, Light, Vibrations, Sound, Climate and Anthropometry. Bubb [1] presented these factors in a discomfort pyramid, with Smell as most important factor and Anthropometry as least important.The goal of this study is to investigate whether the expectations of aircraft passengers are comparable to the hierarchy of the human senses as proposed by Bubb’s discomfort pyramid [1]. A survey has been conducted among aircraft passengers (respondents with flight experience in the last year). In total 183 respondents between 19 and 64 years old (mean: 30.5, SD: 12.8) were asked to rank six different factors: Smell, Light, Vibrations, Sound, Climate and Anthropometry. These factors were presented to the respondents as 15 different pairs (e.g. Smell-Sound), and respondents were asked to indicate for each pair, which is most important
according to them in order to experience comfort. The results of this study suggest that the expectations of aircraft passengers differ from the hierarchy of senses suggested by Bubb [1]. In this study, respondents indicated ‘anthropometry’ as most important, whereas this was the least important factor according to Bubb [1]. The other factors, in reducing order of importance according to the respondents of this study, were 'noise, smell and climate’, ‘vibration’ and, lastly, ‘light’. However, according to the remarks made by the participants, some factors could be interpreted in different ways. For example, climate does not only refer to temperature, but also to humidity and atmospheric pressure. Therefore, these factors and their influence on comfort and discomfort experience should be studied in more detail. ...
