Ergonomic Studies:

Tested multiple configurations with 20 members of the team of multiple heights and body types, with an adjustable cockpit setup

Collected data on preferred seat angle, visibility, steering wheel height, pedal tray adjustability range, elbow, and knee room

Determined position for the sub-belt harnessing tube

Tested steering wheel and headrest ergonomics for user feedback

Seat Assembly Design Goal:

Sturdier, more ergonomic seat design with dimples and flanged edges, fitting various drivers.

Multiple mounting points with bolts and nuts restrain the bending and make the seat stronger.

Design Details:

Added flanges on the side area for stiffer body support
Simple Dimple Die pattern limits the distortion of the back of the seat
Opening for Anti-Submarine Belts
Seat pads allow for adjustment of the driver’s head and line of sight for drivers of different heights

Testing:

Goal:

Test how extra flanged edges and dimples help to reduce deformation due to lateral force under 1.5g acceleration.

Result:

Even flanges for ½ could significantly reduce the deformation of the side of the seat compared to the unflanged sheet metal.
