To adjust the machine with work

Its a laborious and expensive solution, justifiable in a

few exceptional cases.

2. have several fixed sizes

All size must be available and between sized user

may not be accomodated well

3. Make it adjustableBest fit to all people, but the adjustment features

must be easy to use.

MOBILITY

Legs provide us powerful mobility.

Arm provide us with long reaches and

extensive mobility in the shoulder and elbowjoints.

As we move about, we usually combinemovements in several body joints to generatethe flexibility needed. Actual ranges of

motion depend very much on health, fitness,training, skill, age, and any disability.

Dissimilar measuring techniques andinstructions to the clients can cause great

diversity in reported result of mobility rangesof groups of people.

Mobility is not always in the middle of the

range. Some preferred motions occur near the

mean mobility of the body joint. But oftenmotion take place close to a joints flexibility

limits. (example in Table 2.2)

- Chairs are in wide use in the so-called western

countries, such as Europe, the Americas,

Australia/New Zealand.

- Work tasks may be quite different and

require special skill and motions. Unfortunately,

few ergonomic recommendations for non-

western conditions are at hand.

It appears convenient to describe these reach

envelopes for hands and feet as partial spheres

around the temporary locations of body joints.

In reality, several parts of the body may moveat the same time, and force or vision

requirements may establish specific constraints.

Movement of the forearm in the elbow joint,

close to an approximately 90-degree bend,

combine with some rotation in the shoulder,

determines the envelope for fine manipulationand other light work (figure 2.16, 2.17, 2.18)

The operator can cover this area with small

displacements in knee and ankle joints, both

near 90 degrees. This is the best space for foot

activities that require exertion of only smallforce and energy, usually by pushing down the

whole foot, or just the heel or toes.

Foot controls that demand substantial forward-push force from the seated operator must belocated higher and farther away so that the

knee ankle is around 150 to 160 degrees.Pay attention :

- the almost fully extended leg does not allowfor much displacement of the foot.

- A strong backrest is necessary to counteractthe pedal push.

56/56

Frequent operation of pedals is only suitable for

a seated operator : a standing person obviously

can not use both feet simultaneously, and even

use of only one foot would require balancingthe whole body on the other foot.

although birds can stand on one foot for long

time, humans can not do so easily.
