Rising obesity levels mean car makers are having to go to ever more elaborate lengths to accommodate supersized drivers. Mercedes is testing stronger version of the grab handles, so they can cope with extra weight of heavier passengers hauling themselves out of their seats. Ford has increased the size of dashboard buttons so that drivers with large 'sausage' fingers don't accidentally press several at once. And many manufacturers now offer electrically powered steering wheels that lift away from the driver when the engine is turned off, to aid and easier gateway.
Manufacturers are taking a scientific approach to the problem, too. BMW has recruited a group of 800 'guinea pigs' to study mobility in a car's cabin - to help it ensure its models can fit 95% of body size. The firm has developed seats with "comfort adjusters" - adjustable side bolsters that will grip thinner occupants and still be comfortable for larger ones.
Ford and Nissan have created fat suits for engineers to wear while developing control systems, so that buttons can be placed in convenient locations for larger drivers. The suit is responsible for the movement of the hazard light button from below the steering wheel to the top of dashboard.
Examples of inclusive design solutions:
- Steering Wheel: Lifts away from driver when engine is switched off for easy exit from car.
- Dashboard Buttons: Strategically placed and bigger accommodate 'sausage' fingers.
- Hazard Light: Button moved from under steering wheel to top of dash for easy access.
- Seats: Adjustable side bolsters allow larger drivers to get comfortable.
