B4.2 Cockpit Internal Cross Section: - проходное сечение кабины водителя.

B4.2.1 A free vertical cross section, which allows the template shown in Figure 9 to be passed horizontally through the cockpit to a point 100 mm (4 inches) rearwards of the face of the rearmost pedal when in the inoperative position, must be maintained over its entire length. If the pedals are adjustable, they will be put in their most forward position. – свободное вертикальное проходное сечение, которое позволяет пример показанный на рисунке 9 должен быть пропущен горизонтально через КВ в точку 100 мм сзади лицевой стороны самой задней педали когда она в нерабочем положении, должна поддерживаться по всей длине. Если педали регулируемые, они будут поставлены в самую переднюю позицию.

B4.2.2 The template, with maximum thickness of 7mm (0.275 inch), will be held vertically and inserted into the cockpit opening rearward of the Front Roll Hoop, as close to the Front Roll Hoop as the car’s

design will allow. – образец, с максимальной толщиной в 7 мм будет установлен вертикально и будет вставлен в КВ открывающуюся назад от переднего обруча катания, настолько близко в переднему обручу катания насколько это позволяет сделать модель автомобиля.

B4.2.3 The only items that may be removed for this test are the steering wheel, and any padding required by Rule B5.7 “Driver’s Leg Protection” that can be easily removed without the use of tools with the

driver in the seat. The seat may NOT be removed. – единственные вещи которые могут быть убраны для этого теста это руль, и любые уплотнения требуемые правилом Б.5.7 которые могут легко сниматься без использования каких-либо инструментов с водителем в сиденье.

B4.2.4 Teams whose cars do not comply with B4.1 or B4.2 will not be given a Technical Inspection Sticker and will NOT be allowed to compete in the dynamic events. Командам, чьи машины не удовлетворяют Б.4.1 или Б.4.2, не будет дан стикер прохождения технического осмотра и они будут недопущены к соревнованиям.

Note: Cables, wires, hoses, tubes, etc. must not impede the passage of the templates required by B4.1

and B4.2.примечание: кабели, провода, шланги, трубы и тд не должны мешать прохождению образца требуемого правилом Б.4.1 и Б4.2

B4.3 Driver’s Seat – сиденье водителя

B.4.3.1 The lowest point of the driver’s seat must be no lower than the bottom surface of the lower frame rails or by having a longitudinal tube (or tubes) that meets the requirements for Side Impact tubing, passing underneath the lowest point of the seat. – низшая точка сиденья водителя должна быть не ниже чем поверхность дна поручня нижнего каркаса или имея продольную трубу(ы) которые удовлетворяют требованиям для труб бокового удара, проходящих под низшей точки сиденья.

B.4.3.2 When seated in the normal driving position, adequate heat insulation must be provided to ensure that the driver will not contact any metal or other materials which may become heated to a surface

temperature above sixty degrees C (60°C). The insulation may be external to the cockpit or

incorporated with the driver’s seat or firewall. The design must show evidence of addressing all three

(3) types of heat transfer, namely conduction, convection and radiation, with the following between

the heat source, e.g. an exhaust pipe or coolant hose/tube and the panel that the driver could contact,

e.g. the seat or floor: - в нормальном сидячем положении для вождения, соответствующая теплоизоляция должна быть обеспечена чтобы гарантировать что водитель не коснется какого-либо металла или других материалов температура поверхности которых могла бы быть более 60 градусов по цельсию. Изоляция может быть внешней для КВ или объединена с водительским сиденьем или брандмауэром. Модель должна предоставлять доказательство адресации всех трех типов теплопроводности, а именно проводимость, конвекция и излучение, со следующими источниками тепла, то есть выпускной трубопровод или шланг охлаждающей жидкости/труба и панель чтобы водитель имел контакт, то есть сиденье или пол:

a. Conduction Isolation by: - изоляции проводимости путем:

i. No direct contact between the heat source and the panel, or

ii. A heat resistant, conduction isolation material with a minimum thickness of 8 mm (0.3

in) between the heat source and the panel. – отсутствия прямого контакте между источниками тепла и панелью, или теплостойким изоляционным материалом с минимальной толщиной в 8 мм между источником тепла и панелью.

b. Convection Isolation by a minimum air gap of 25 mm (1 inch) between the heat source and

the panel - изоляция теплоотдачи путем минимального воздушного просвета в 25 мм между источником тепла и панелью

c. Radiation Isolation by: - изоляция излучения путем:

i. A solid metal heat shield with a minimum thickness of 0.4 mm (0.015 in) or

ii. Reflective foil or tape when combined with a.ii above. – крепкого металлического теплостойкого щита с минимальной толщиной 0,4 мм или с помощью отражающей фольги или ленты совместимой с а.ii сверху.

B4.4 Floor Close-out – закрытие полов

All vehicles must have a floor closeout made of one or more panels, which separate the driver from

the pavement. If multiple panels are used, gaps between panels are not to exceed 3 mm (1/8 inch). The

closeout must extend from the foot area to the firewall and prevent track debris from entering the car.

The panels must be made of a solid, non-brittle material. – все ТС должны иметь закрытые полы с одной или несколькими панелями, которые отделяли бы водителя от тротуара. Если используются разнообразные панели, щель между панелями не должны превышать 3 мм. Покрытие должно протягиваться от зоны где находятся ступни до брандмауэра и должно предотвращать выпад развалившихся частей из машины. Панели должны быть сделаны из крепкого, нехрупкого материала.

B4.5 Firewall - брандмауэр

B4.5.1 A firewall must separate the driver compartment from all components of the fuel supply, the engine oil and the liquid cooling systems. It must protect the neck of the tallest driver. It must extend

sufficiently far upwards and/or rearwards such that any point less than 100 mm (4 ins.) above the

bottom of the helmet of the tallest driver shall not be in direct line of sight with any part of the fuel

system, the cooling system or the engine oil system.

B4.5.2 The firewall must be a non-permeable surface made from a rigid, fire resistant material.

B4.5.3 Any firewall must seal completely against the passage of fluids, especially at the sides and the floor of the cockpit, i.e. there can be no holes in a firewall through which seat belts pass.

B4.5.4 Pass-throughs for wiring, cables, etc. are allowable if grommets are used to seal the pass-throughs.

Also, multiple panels may be used to form the firewall but must be sealed at the joints.

B4.6 Accessibility of Controls

All vehicle controls, including the shifter, must be operated from inside the cockpit without any part

of the driver, e.g. hands, arms or elbows, being outside the planes of the Side Impact Structure defined

in Rule B3.24 and B3.31.

B4.7 Driver Visibility

B4.7.1 General Requirement

The driver must have adequate visibility to the front and sides of the car. With the driver seated in a

normal driving position he/she must have a minimum field of vision of two hundred degrees (200°) (a

minimum one hundred degrees (100°) to either side of the driver). The required visibility may be

obtained by the driver turning his/her head and/or the use of mirrors.

B4.7.2 Mirrors

If mirrors are required to meet Rule B4.7.1, they must remain in place and adjusted to enable the

required visibility throughout all dynamic events.

B4.8 Driver Egress

All drivers must be able to exit to the side of the vehicle in no more than 5 seconds. Egress time

begins with the driver in the fully seated position, hands in driving position on the connected steering

wheel and wearing the required driver equipment. Egress time will stop when the driver has both feet

on the pavement.
