Driver Capsule concept is comprehensive in its treatment of
every recognized aspect of the means of reducing the G forces acting
on the human physique. However, are-thinking of the urgency of the
need to deal effectively with basilar skull fracture and hyperextension
of the neck has led to a different approach to achieve acceptance,
to accelerate the development and to bring the Basic Driver Capsule
version into production and wide use in the shortest possible time.
This policy recognizes that the racing community demands a simple,
inexpensive retrofit that can be available in months, rather than
the time that fabricators contemplate when presented with the broad
comprehensiveness of the complete Driver Capsule design.(See also the Fitch Full Driver Capsule)
Basic Driver Capsule incorporates only the principal
feature of the original, the hinged seat-back - the feature
that reduces life-threatening accelerations more effectively
than anything currently proposed. Reduced to essentials, the
original metal hip hinge is replaced by a seat-back pivot integral
with the lap belt and its anchor, as illustrated.
seat-back pivots at the driver's hip. The lap belt threads
through slots, thus the mechanical hinge of the original design
is replaced by a second function of the lap belt in the Basic
Driver Capsule. Multiple slots for the lap belt and the
shoulder straps through the seat-back accomodate all drivers.
the belt in this manner may be controversial in view of the
recent focus on belt efficiency related to its alignment.
Any secondary use of belts must have the full approval of
all parties. Without it, the use of the belts will revert
to the original metal hinge.
