Different variations of use are possible. In addition the chair can provide a backrest, that travels within a horizontal concave way, swinging mounted (suspended from a high fixing point) forearm rests that lock to help one rise, and movable and lockable leg supports plus antiglare lighting. (version A1, A1,2 or A1,2,3 etc.)
Version B has the drive integrated in the seat itself and
is a compact design. Therefore it can be carried out as chair (adding legs
or post with 5 wheels), seat/standing seat (adding a base with a gas spring
for alternating between heights), footstool (with short or no legs) and/or
standing space (positioned flat on the ground, without legs).
Version B (Fig.5) is qualified as a introductory model due to low production cost and it's versatility .
Since the times of ,,homo erectus" man is used to the passive
following of an active motion or movement in seated position such as being
carried as a child on the hips of the mother or horseback riding. This is
carried out unconsciously and without muscle tense up, having the affect
of being very relaxing but not tiresome, and having a therapeutical use.
Because the motion is resilient gentle and slow, an ergonomic seating position will be encouraged if not enforced., many muscles in the pelvic area will be used without tension and the upper body can be kept steady. This will support blood circulation of the entire body the (intervertebral) disks will experience a softly varying strain and the upper thighs will be relieved of pressure.
This chair will enhance the well-being, will result
in a feeling of security and safety, without
having a tiresome effect, and being moved slowly will not distract from the actual work because one follows the motion unconsciously.
The user will realise an upgrading of his workplace,
what will result in a better work climate. The therapeutical benefit
is not to be underestimated
That the chair can be employed in home workplaces or private use also, results in quite a large market.
Conventional chairs, like chairs similar to rocking chairs,
swivel chairs, chairs to kneel on or balls to sit on have all different disadvantages
in reference to ergonomic seating. They either lead to relatively crouched
or cramped upper body posture with a round back, which is bad for spine and
disks and will eventually give backaches, or in case of the kneeling chair
the body weight puts pressure on the crucial ligament. Besides one can sit
wrong in the best ergonomic chair because it does not force into an upright
position resulting in backaches, aches of the neck- and shoulder region and
too large seats in a wrong angle will restrict blood flow.
Extract from the brochure ,,Telearbeit" (Teleworking) of the German ministries of BMA ,BMWi and bmb+f, page 92, § 4.5:
In his working life an office worker spends approximately 80.000 hours mostly seated. If only for that reason the chair should be better than the standard calls for. An american study claims that a bad office chair will swallow up five minutes of productivity every hour. Pains and aches and loss of working capacity are held responsible for this unusual result.
This chair will meet the following requirements, to provide:
(Fig.5)can be used as a (moving) standing space
(for instance for work at machine tools) (like standing on the helm of a
sailing yacht) and
adding legs it is a heatable footstool,
adding longer legs or any kind of solid base it is a chair similar to Version A,
adding a special base with a gas spring it is a chair that can alternate between the position of sitting and standing and supports to get up to standing position too,
besides it can be built in into a car seat.
In addition the backrest can be a pillow type neck- and backrest for use on couches, camp beds or beds to maintain a reading position or to help getting up or sitting up, plus it is useful after plastic surgery of the face.
Multiple variations of design with many options within the levels of specification are possible.
Prototypes (of version B) have been built.
