[0034] The invention further encompasses a system, comprising the
wearable sitting posture assisting device and comprising at least
one alternative individualization assembly, which is configured for
at least partly replacing the individualization assembly in order
to implement an alternative wearable sitting posture assisting
device together with the functional assembly. In particular, the

respectively, or vice versa.
[0057] In the case shown, the person 200a wears the leg unit 102a
on a right leg 204a. The leg unit 102a is arranged on a rear side
211a of the leg 204a of the person 200a. Furthermore, the person
200a wears the additional leg unit 104a on a left leg 206a. It is
also conceivable that a person wears a leg unit on a left leg and
an additional leg unit on a right leg. Furthermore, it is
conceivable that a person only wears one leg unit. In addition, it
is conceivable that a wearable sitting posture assisting device
comprises only one leg unit. It is also conceivable that a leg unit
is arranged on a lateral side of a leg and/or on a front side of a
leg and/or between two legs of a person.
[0058] The person 200a sits or partly sits on the wearable sitting
posture assisting device 100a in a sitting direction 134a. The
person 200a faces and/or looks in the sitting direction 134a when
facing forward. The sitting direction 134a is oriented parallel to
a ground on which the person 200a is sitting or walking or

direction which is oriented parallel to the upper leg longitudinal
axis 110a. The upper leg longitudinal axis 110a is oriented
parallel to a main extension direction of a thigh 208a of the leg
204a of the person, in particular when the person 200a sits, and/or
partly sits and/or walks and/or stands up and/or stands while
wearing the wearable sitting posture assisting device 100a.
[0060] The wearable sitting posture assisting device 100a comprises
a seat unit 112a. The seat unit 112a is connected to the upper leg
support 108a. In the partly sitting posture and/or in the sitting
posture the person 200a sits on the seat unit 112a. In the case
shown the person 200a sits on the seat unit 112a and on a seat unit
114a of the additional leg unit 104a in the partly sitting posture.
The seat unit 112a comprises a sitting element 116a. The sitting
element 116a contacts the thigh 208a of the person 200a.
Furthermore, in the sitting posture and/or in the partly sitting
posture the sitting element 116a contacts a buttock 210a of the
person 200a. The seat unit 112a comprises a sitting surface 118a.
The sitting element 116a comprises the sitting surface 118a. The
sitting surface 118a is configured for allowing the person 200a to
sit down on it with his thigh 208a and/or with his buttock
210a.
[0061] It is also conceivable that a wearable sitting posture
assisting device comprises only one seat unit, in particular a
common seat unit of two leg units. In particular, in this case it
is conceivable that the seat unit is saddle-shaped and/or
implemented in the manner of a saddle, in particular arranged
between the legs of a person.
[0062] The wearable sitting posture assisting device 100a comprises
a lower leg 124a. The lower leg 124a comprises a lower leg support
126a. The lower leg 124a has a lower leg longitudinal axis 128a.
The lower leg longitudinal axis 128a is oriented perpendicularly to

sitting direction 134a and a surface normal of a ground the
wearable sitting posture assisting device 100a is standing on in
the normal wearing condition. The lower leg longitudinal axis 128a
and the upper leg longitudinal axis 110a are arranged in a common
plane. The lower leg support 126a has a main extension direction
which is oriented parallel to the lower leg longitudinal axis 128a.
The lower leg longitudinal axis 128a is oriented parallel to a main
extension direction of a shank 212a of the leg 204a of the person
200a, in particular when the person 200a sits, and/or partly sits
and/or sits and/or stands while wearing the wearable sitting
posture assisting device 100a.
[0063] The upper leg 106a and the lower leg 124a define a sitting
angle 130a. The sitting angle 130a is an angle included by the
upper leg longitudinal axis 110a and the lower leg longitudinal
axis 128a. The sitting angle 130a is similar or identical to an
angle between the thigh 208a and the shank 212a of the person 200a.
The sitting angle 130a having a value between 60.degree. and
130.degree., in particular a value of approximately 90.degree.,
corresponds to different sitting postures or to at least one
sitting posture. The sitting angle 130a having a value between
130.degree. and 170.degree. corresponds to different partly sitting
postures. In case the person 200a is standing while wearing the
wearable sitting posture assisting device 100a, the sitting angle
130a has a value between 160.degree. and 180.degree., in particular
a value of approximately 180.degree.. In case the person 200a is
walking while wearing the wearable sitting posture assisting device
100a, the sitting angle 130a may significantly differ from
180.degree., in particular in case the person 200a bends his knee
202a. In the sitting posture and/or in the partly sitting posture
and/or when standing, the sitting angle 130a and an analogously
defined additional sitting angle of the additional leg unit 104a
are advantageously identical. However, it is also conceivable that
the person 200a may sit on the wearable sitting posture assisting
device 100a in a sitting posture or a partly sitting posture with
the sitting angle 130a and the additional sitting angle differing,
in particular by up to 5.degree., by up to 10.degree., by up to
15.degree., by up to 20.degree., by up to 30.degree., by up to
40.degree., or more. When the person 200a is walking while wearing
the wearable sitting posture assisting device 100a, the sitting
angle 130a and the additional sitting angle may significantly
differ, for instance in case the person 200a bends one of his knees
202a more than his other knee 202a.
