Sammanfattning
The new generation of electric cars and future generations of autonomous cars will change
behaviors while charging and driving, creating opportunities where one can relax in the car. This
master thesis aimed to investigate how added support systems for lower legs and feet in Volvo cars
are valued by users, and how these support systems should be designed to suit different drivers to
improve sitting comfort during non-driving scenarios, such as waiting while charging or riding an
autonomous car. The process has been user-centered and iterative, starting with scope definition
and continuing with two user tests. The first user test focused on the design of the leg support,
including size, shape and placement. The second test focused on how to maximize sitting comfort
with leg and foot support, testing with and without the leg and foot support and with the user in
different torso angles. Test results were analyzed quantitatively and qualitatively, showing that
people sit most comfortably in a freely chosen seat back angle with both leg and foot support.
Guidelines for how the leg support should be designed and the foot support should be positioned
have been developed based on the user test results. The guidelines were then a basis for the final
prototype that was made
