The new Shoei CW-1 Visor

NEW CW-1 Visor and Q.R.S.A System
Real Innovation
Brand New CW-1 Visor and Q.R.S.A. System (Europe)
Essential factor in mid and long term product
planning as a top manufacturer in a category
of premium helmet!!! It is to continue changing
always in order to realize profit and satisfaction
of customers continuously in a high level even
if current products are highly assessed.
CX-1 visor which SHOEI developed for the first
time in the industry as a visor integrated with
mechanism without separate cover created
various merits such as flush surface and one
touch removing/fixing. Its original design has
1
been a main stream of visor design followed
by many other manufacturers. Because of its
prominence of basic design we had been maintaining the basic structure of visor mechanism
for a long time. However, when we considered
what SHOEI full-face model of next generation
shall be, we fond it necessary to review design
including a visor mechanism from scratch for
further satisfaction of customers. As a result,
brand new CW-1 visor and Q.R.S.A. (Quick
Release Self Adjusting) System were born as
a real innovation.

2. Q.R.S.A. (Quick Release
Self Adjusting) System
1. Development Concept
As mentioned above, CX-1V visor had many
merits. What were developed for further convenience of users maintaining CX-1V’s merits
are CW-1 visor and Q.R.S.A. Base Plate. Specifically, we studied the points below as high
priority issues for convenience of users:
• To improve upper vision when Pinlock
Fog-Free Lens is equipped;
• To secure close contact of a visor and
a window beading while a visor is fully
closed;
• To realize easy adjustment of a base plate
for close contact of a visor; and
• To maintain smooth opening/closing of
2-D visor for racing same as 3-D visor for
general use
In addition to above, we found it important to
maintain and refine further the following merits
of current CX-1V:
• Easy and firm removing/fixing of a visor by
one action; and
• Elimination of visor’s fogging by pre-set
opening and a visor lock mechanism by
handling of a lever

• Variable Axis
There are several factors for a position of a rotation axis for opening/closing of a visor.
Securing full vision, positional relationship between inner surface of a visor and a shell or
parts, relation with a shell shape design and
relative angle of contact with a window beading for close contact have to be considered.
For some of these factors a rotational axis shall
be positioned rearward while it had better be
positioned forward. In order to resolve these
contradictory requirements comprehensively,
we applied in Q.R.S.A. System a variable axis
mechanism where an axis is moved front and
rear corresponding to opening/closing angles.
This mechanism made it possible to extend
Pinlock Fog-Free Lens upward and improved
close contact with a window beading further.

Structure and Components of Q.R.S.A. Base Plate
A Base Plate consists of an inner plate fixed to
a shell and an outer plate supporting a visor,
and sliding of an outer plate to the front and
the rear changes position of an axis.
When a visor is fully closed, an outer plate is
pressed rearward by 2 springs, assists close
contact of a visor and a window beading and
performs as an allowance for adjustment of
position of Base Plate.
Sixteen components of Q.R.S.A. Base Plate
were newly developed and for each of these
components such factors as strength balance,
3
sliding characteristics and light weight were
checked comprehensively to realize perfect
movement.

A visor developed together with Q.R.S.A. Base
Plate is CW-1. Both horizontal and vertical dimensions are enlarged so that it may correspond to extended vision caused by a wider
eye port.
a long time. Long experience and high technology for mold designing realized clear vision
with minimum distortion. Almost 100% of UV
ray is blocked and hard coating is applied to
protect from scratch.
A rib on an inner top of a visor eliminates step
with Pinlock Fog-Free Lens and realizes rigidity of a whole visor and flush surface with a
shell. A surface of an enlarged knob for opening/closing of a visor is adjusted to a direction
of visor opening for smooth handling.
CW-1 is made of polycarbonate and 3-D
molded as has been developed by SHOEI for
4. Characteristics of Q.R.S.A. + CW-1 Visor
• Substantially Extended Upper Vision of
Pinlock Fog-Free Lens
New shaped Pinlock Fog-Free Lens with extended vision is designed for Q.R.S.A.+CW-1
Visor. Combination of 2 layers structure with
air chamber between a visor and a lens and a
special coated anti-fog lens restrains fogging
and secures clear vision.
We received request to improve upper vision of
Pinlock Fog-Free Lens in a riding position leaning forward from many customers for former
model. In Q.R.S.A.+CW-1 Visor, we succeeded
4
in moving top end of Pinlock Fog-Free Lens
and silicone sealing out of vision by methods
below;
a) Control of Visor’s Movement by Variable
Axis;
b) Application of Rib at Inner Top of Visor to
Make Height of Visor’s Inner Surface Same
as Pinlock Fog-Free Lens
c) Extension of Visor Upward to Position Top
End of Pinlock Fog-Free Lens in Overlapping
Portion of Shell and Visor. Extended clear vision enhances comfort and concentration in
rain or low temperature which makes a visor
easy to fog.

• Improved Close Contact of Visor and Window Beading
By application of a variable axis, an angle of
contact with a window beading becomes perfect when a visor is fully closed and secures
firm close contact all through circumference.
And also, when a visor is fully closed, an outer
base plate is pressed rearward to a direction
of a window beading by 2 springs and assists
close contact.
An improved close contact of a visor and a
window beading enhances wind breaking effect, and therefore, air turbulence around face
inside a visor is decreased and quietness is
improved by decrease of noise from around a
visor.
Structure of a window beading is also renewed
in new models applying Q.R.S.A+CW-1 Visor.
An upper portion is elastic in lip shape while
side portion and a bottom are in curled and
lip shapes respectively to secure close contact with a visor which is sliding rearward by
Q.R.S.A. System.
• Easy Adjustment of Visor Position
A careful positioning of screw was required in
former fixed axis type base plate for adjustment of a visor position.
In Q.R.S.A. + CW-1 Visor, a fully closed visor
is always pressed to a direction of a window

beading by positioning of a variable axis and
springs. This self adjustment mechanism allows minor difference and makes the system
perform properly. Adjustment of a visor position when a screw is loosened is easy due to
this tolerance.
NEW CW-1 Visor and Q.R.S.A System
• Corresponding to a Wider Eye Port
CW-1 Visor is designed to correspond to a wider eye port compared to a former model. An
extended vision contributes to a safe and comfortable riding.
• Easy One Action Visor Fixing/Removing
Easy fixing/removing favored in SHOEI visor
is succeeded to Q.R.S.A.+CW-1 Visor. To remove a visor, just open a visor fully, pull trigger
of Q.R.S.A. Base Plate downward and release

hook and gear. To fix it, press hook and gear
to Q.R.S.A Base Plate until it clicks in a same
fully opened position. It is very easy. You can
handle watching hook and gear by your eyes.

• Flush Surface and Round Shape contributing to Quietness
Q.R.S.A.+CW-1 Visor is in a coverless structure without any component located on a visor
to support it. Flush surface without unnecessary joint or step does not cause air turbulence
or an excessive air stream on a shell surface
and contributes to quietness. And, a rib at top
end of a visor minimizes gap with a shell. Thin
side ends improves flush surface with a shell.
Surface of mechanical portions in both sides is
designed in a 3-D round shape to fit to a shell.
fully opened position. It is very easy. You can
handle watching hook and gear by your eyes.
• Pre-set Opening and Visor Lock
SHOEI’s own visor lock and pre-set lever to
keep a visor in a slightly opened position are
improved further in Q.R.S.A. System for easy
handling. By moving a lever downward from a
standard position while a visor is fully closed,
an outer base plate slides forward and creates a slight gap between a visor and a window beading. A proper introduction of outer air
eliminates or avoids fogging. A visor is locked
and a sudden opening of a visor is avoided
when a lever is moved upward.*
* A visor may be opened even if it is locked when an excessive force is applied.

5. Newly Developed CWF-1 Visor for Races
A tear off film is essential in races. CWF-1 Visor equipping hooks to fix tear off films is also
newly developed. A visor surface is required to
be in 2-D to fix tear off films. In a former model,
there was a difference in angle of contact with
a window beading between 2-D visor for races
and 3-D visor for general use.
Therefore, opening and closing of 2-D visor was
not smooth as those of 3-D visor. In CWF-1 an
area inside an eye port to fix tear off films is
in 2-D while an area contacting with an window beading is in 3-D same as that of CW-1.
Additionally, movement of a variable axis of
Q.R.S.A. Base Plate secures smooth opening/
closing and close contact with a window beading while a visor is fully closed. Pinlock pins
are equipped to CWF-1 Visor for use of an exclusive Pinlock Fog-Free Lens for CWF-1. An
upper vision is, of course, secured for CWF-1
same as CW-1 when Pinlock Fog-Free Lens is
fixed. Intervention of tear off hooks and Pinlock pins is resolved by use of a single axis
component for both pins and hooks.

Both pins and hooks are in eccentric structure
for adjustment of tension and may be adjusted
separately. As a structure for rotation and fixing
in adjustment of eccentric mechanism for tear
off films, a radial spring is newly applied. When
a tear off hook is pushed, it rotates while it is
fixed when a tear off hook and a washer are
combined by a righting moment of spring. Use
of this mechanism realized easy adjustment of
a tear off hook without using a screwdriver.
