Hoffmann Group 47 Swivel work chairs Base-Tec How to select your optimum work chair: 1. Seek out the suitable surface: Wood PU- The economy version: simple, competitive, stain-resistant (e.g. in a training workshop). The allrounder: soft, practical and robust (e.g. in industrial factory areas). Synthetic leather - The comfortable one: comfortable, soft and washable (e.g. in the drawing office). Available in ESD version. Fabric - The breathable option: soft, comfortable and breathable (e.g. in a foreman's office). Available in ESD version. How to select your optimum work chair: 2. Select the correct frame: Wear-resistant large pad feet. Suitable for: Working when applying considerable force or performing very fine motor movements. When the floor is extremely dirty. For chairs with seat height above 650 mm, DIN 68877 prohibits the use of castors. Load-responsive castor braking for hard floors. Suitable for: All applications not covered by the use of floor pads. Note: Castors can easily be fitted in place of pads. Pad feet cannot be fitted in place of castors (the gas pressure spring would strike the floor). After selecting the work chair, it has to be adjusted for the optimum seating posture, appropriate to your work and to your physical size. 1. Set the seat height correctly: 90-degree rule: approx. 90 degrees between upper arm and forearm when the forearm is resting horizontally on the work surface. At least 90 degree angle in the knee joint when the foot is placed flat on the ground. The feet must have solid contact with the ground or the footrest. Use the whole of the seat area. Stay in contact with the backrest. 3. Adjust the seat angle: Most workplaces in production require a forward leaning working position. Ttie seat inclination setting should be chosen to maintain a body posture angle of at least 90 degrees and to reduce pressure on the thigh area. This ensures even blood circulation and effectively avoids sitting with a hunched back. 2. Backrest height adjustment: Adjust the backrest so that the lumbar support presses against your backbone and supports it in the region of the 3rd and 4th lumbar vertebrae (about belt height). 4. Continuous contact with the backrest for dynamic sitting: The backrest automatically tracks every movement of the upper body. The back is supported at all times. This enables dynamic sitting, in which the musculature remains relaxed and the backbone and spinal discs are not subjected to loads. The permanent contact backrest can be locked into any desired leaning position, if you are performing work that demands precise motor control, restraint or application of force. ESD - Electrostatic Discharge ESD means electrostatic discharge of charged objects or persons. Electrostatic discharges can cause damage to micro-electronic components, since in relation to mass the energy in a static discharge has the same effect in a semiconductor as the energy in a bolt of lightning when it strikes a tree.
