There are rules like the minimum size of the cockpit opening and the cros sections. Seats are not interchangeable between seats. If Russell would move to merc any time soon, they have to make the cockpit a bit larger in W12/13Jolle wrote: ↑Mon Dec 07, 2020 2:40 pm[quote=notsofast post_id=943955 time=<a href="tel:1607347869">1607347869</a> user_id=15794]
Russell may have been robbed of a win, but he was certainly given the opportunity to demonstrate whatever skills he listed in his PowerPoint presentation.
On a more serious note, why couldn't he fit in Lewis' car? Aren't the dimensions of the survival cell standardized? Couldn't he have just taken his fitted Williams seat and stuffed it in the Mercedes?
The rules state a minimum width and height on two planes named A-A and B-B. The drivers feet at the rearmost pedal position must be 300mm behind A-A. The chassis is 300x275mm (w x h) with a 25mm radius on each corner at AA, and 450x400mm with r50mm at BB. The minimum length between A and B is 925mm and the volume has to grow linearly so the height at the pedal is ~315mm. However the length of the safety cell can be longer - which has some aero advantages to move the sidepod back from the wheels and increase bargeboard length - which reduces the height at the drivers pedals. Merc have one of the longest cars so you can assume the safety cell is part of the reason for that and with a smaller driver foot they can get away with minimising the cross section of the safety cell.
The rules for 2022 already have a slightly bigger minimum volume for the drivers legs/feet.
