Workplace design centres on human needs as the measure of all things

The aims and tasks of ergonomics:

  • To design work practices and workplaces in keeping with people’s needs
  • To ensure that the work environment and equipment create ideal work conditions
  • To minimise the strain to which people are subjected at work

People and ergonomics.
The most common problem when sitting: Sitting with a hunched back

  • The longitudinal ligaments of the spine and intervertebral disc become increasingly slack and shorter
  • Shoulder, back and neck muscles are subject to static strain

Possible consequences:

  • Neck pains, back pains, general fatigue
  • Pressed-in stomach, detrimental effects on digestive organs
  • Negative effects on the muscles
  • Lack of concentration and tiredness due to reduced circulation of blood and lymphatic fluid

The remedy from Klöber

An ergonomically effective chair must be adaptable to the user’s individual needs and type of work.

 

The quality of an office chair thus hinges on its capacity to implement the ergonomic requirements of dynamic seating and to accommodate the user’s individual anthropometric characteristics, such as weight and size.

Movement is the key to sitting correctly

Dynamic seating: Avoids dangerous one-sided strain by regularly changing the seated posture.

 

Industrial health experts prescribe continuous switching from a forward (upright) posture through an open posture to a relaxed, leaning-back posture.

  • Alternating use and relaxation of muscles and intervertebral discs
  • Improves nutrition of the discs which are particularly at risk
  • Avoids straining the intervertebral discs
  • Enhances the sense of well-being
  • Stimulates the natural metabolic processes
  • Supplies the muscles with fresh oxygen
  • Prevents static muscular tension and premature fatigue

The Klöber Synchro mechanism

The point-synchronised motional sequence guarantees that the backrest follows the movement of the back precisely – without any “shirt-pulling” effect.

Klöber’s patented quick-set adjustment to the user’s body weight

Klöber’s innovative, patented quick-set adjustment mechanism enables user-friendly, simple and convenient fine adjustment to the user’s body weight over a broad range.

A handle permits adjustment to any body weight between 45 kg and 125 kg.

Basic seat tilt / tilt adjustment

The seat angle should always be adjustable: A forward tilt of up to –3° is ergonomically expedient when adopting an upright, i.e. forward seated posture.

  • Prevents sitting with a hunched back
  • Conducive to an upright position for pelvis and spine (“lordotic curve”)
  • Prevents congestion of the blood flow in the thigh area

Seat suspension

Even in its lowest position, the seat surface should have a suspension depth of at least 1 cm.

Klöber ensures this by means of a pneumatic spring with rubber dampening.
The impact which occurs when sitting down on the seat in its lowest position is absorbed and the strain on the intervertebral discs is relieved.

Seat depth adjustment

Seat depth adjustment (sliding seat) is ergonomically recommendable to enable individual adaptation to different thigh lengths, particularly for tall people.

Backrest shape and backrest height adjustment

Anatomical shaping of the backrest contours in longitudinal and transverse directions and optimum adaptation to users of different sizes and proportions are important in order to ensure that the backrest affords full support. The backrest then effectively relieves the strain on the back muscles and intervertebral discs.

Armrests

Far from being a mere status symbol, armrests on an office chair fulfil key ergonomic functions and play a vital role in ensuring well-being ain the workplace:

  • They afford support when standing up and sitting down (the spine is lowered onto the seat’s upholstery without jolting)
  • They relieve the strain on the muscles of the shoulders and the upper arms
  • They relieve tension in the area of the neck and the cervical vertebrae
