D. THE HELMET
9. CHIN BAR
The E1 is equipped with a chin bar that pivots up and can be easily opened
and closed by means of the operating element located in the middle of the
chin bar. The movement of the section required for this is optimised for
convenient, smooth operation.
LOCK SYSTEM
The chin section is equipped with a specially developed lock system on the
left and the right side. The construction design of the lock system is similar
to the door lock systems used in car design. Despite there being locks on
both sides, the chin section opens with only one button. The lock in the
opposite side is simultaneously operated by bowden cable.
The mechanically optimised system reduces the force need to operate the
two locks to a comfortable 16 N, although the safety-relevant overall locking
force is many times this amount.
OPERATION
The chin bar can be opened at any time irrespective of the position of the
visor or sun visor. The stiff, positive engagement at the end of travel ensures
the chin bar remains safely in place when raised.
OPENING THE CHIN BAR
1. Open the chin bar by sliding the red
button located in the middle of the chin
zone forwards in the direction of the
arrow as far as it will go, using your
thumb.
