Merritt engineering and biological research ergonomics fixed seat body showed sedentary can cause illness and musculoskeletal disorders. Home, office and automobile industry will use the study to improve seating comfort and reduce complications. But so far, only a very small number of public seating manufacturers realize the importance of sound ergonomic design. Despite sitting in stadiums will not lead to musculoskeletal disorders, but reasonable seat design helps reduce the discomfort caused by sedentary. With the deepening development of ergonomic research, experts have gradually begun to develop standards after the seat design. By leading companies to hire a professional designer ergonomic chair experts and to jointly design new fixed seats, and launched in durability, safety line, in terms of comfort and taste of leading Hess? Venues fixed seats. Leading by three fixed seat section to achieve comfort: the seat, back and armrests, to assess whether they meet the standards, and each member has a specific ergonomic basis. Curved seat surface of the first part of the chair seat base curve reasonable than any plane seat, can make sedentary people feel more comfortable. Pressure on the ischial tuber (pelvic floor protruding bones) causes hip pain and discomfort. After sedentary can cause poor blood circulation to the body portion. However, the curve of the seat surface pressure can be distributed to more areas, reducing local pressure, promote blood circulation. Combined with back and seat surface, so that the chair of the ischial area to provide more support. Curved surfaces can be applied to the pelvis The pressure is distributed to the peripheral parts of the body, which greatly reduce the pressure on the pelvis. Transition the front edge of the seat cushion sofa traditional flat Hisaza likely to cause physical discomfort, numbness legs and feet. Angular edge will increase the pressure on the hamstring muscles and thighs popliteal arteries, these pressures will reduce the venous blood circulation. Round the outside corner chair should be rounded to fit the asymmetrical sitting or legs open posture. Legs open when seated, lower pressure is passed on to the thigh high thigh. Gradual transition will reduce the pressure on the outer arc of thigh high. Pelvic: Seat curve to provide appropriate support to the pelvic, pelvis called intermediate micro height, this part of people sitting in the chair to reduce the forward part of the opportunity slip. Thus helping to maintain the correct posture, and enough space for the legs. Leader in providing consistent support fixed seats while reducing pressure on the hips. The design also can be spread all throughout the seat weight, reduce the pressure on the sciatic tubers and sensitive parts of the thighs, avoid sedentary or plane seat hip caused numbness. Seat also has front and edge transition radian angle, at any sitting position, can reduce pressure on sensitive parts of the thighs. Leading fixed seats with a special design tailbone, you can make comfortable seating, to prevent slipping forward. In the seated positioning, handrails play a very important role. Conducive to correct posture, without causing hump. The second part of the seat back tilt-back chair should provide proper support to the body, the main role is to provide torso stability and back muscles relaxed. 10o inclination of the seat back is the key to the trunk of the body. Chair should tilt backwards at an angle of 8o-15o in order to support and stabilize the torso. Studies have shown that a reasonable seat back inclination can be reduced back pressure, so that the body is more comfortable in this situation, so that in a relaxed state. Cooperating with the back, while the seat should be half inclined, if not synchronous modification, the body easily forward slip. Lumbar support curve is significantly affecting the back seat comfort and posture. Anatomically, the waistline upper torso was so natural before the bow, to avoid lower back discomfort. The current measure has been determined ergonomic seat body should first 1-5 lumbar vertebrae provide support. Leading fixed seats depending on the shape of the human spine itself, the choice of bentwood manufacture S-shaped profile, while the chest and lumbar spine to provide support when seated at random, to reduce after hip angle and vertebral ligaments and muscle strain. 12o curved surfaces and longer the back is the spine of auxiliary support systems, while leaning back, the outline of the body upper portion of the support provided to reduce the pressure on the spine, helping to reduce back fatigue. The third part of the leading fixed seat armrest ergonomics will be mainly introduced to the unique design of the armrest is provided sufficient leg space and provides support arm. Whether continued use or for temporary use, armrests reflects its importance. Designed armrests person's weight can be dispersed to other ancillary support systems. This helps to reduce the pressure on the weight of the dispersion seat and back of the right armrest installation helps stretch the upper chest and back bone, eliminating the hump phenomenon caused by sitting right in. Internal modeling handrail while reducing pressure on the elbow, avoid numbness. Grab the front surface of the circular can avoid being hit, the pain caused by injury, rounded edges while reducing the possibility of the clothes were hung or torn. And edge angle of the seat, like handrails shall meet irregular posture (eg legs open posture), so the legs can be placed under the armrest. The main technical performance Merit seat one, the mechanical properties (refer to ASTM Test Method ASTM and GB / T 10357.3-1989 test method) 1, fully enclosed hinge can successfully withstand 350,000 operations, lubricate spring fatigue does not occur, or bearing wear can be measured. 2, the seat impact resistance: can successfully withstand 40 pounds of sand bags 1000 shocks; sand bags should fall on the central chair, distances of 6 inches (Note: 1 inch = 2.54 cm), 8 inches, 10 inches , 12 inches; the striking frequency of 18 times per minute; total 4000 hit. 3, the back swing horizontally resistance testing capabilities: withstand 40,000 times staggered swing cycle impact (using two opposing 40 pounds of sandbags). Sandbags should be level and peer movement, tested on the following distances are 10,000 times: 6 inches, 8 inches, 10 inches, 12 inches; the striking frequency of 36 times per minute. 4, the seat static load capacity: The seat can be long-term support and tolerance 2700N evenly distributed static load. 5, the seat backrest static load capacity: back are long-term tolerance evenly distributed static load 950N, with an angle of 45 degrees upward pressure to the back of the seat. 6, handrails static load capacity: seat armrest 950N can support evenly distributed static load, load a direction perpendicular to the axis urging handrail. Second, anti-UV and anti-aging properties (refer to ASTM G 154 Cycle 1 testing methods and QB / T2601-2003) The seats with special paint, anti-UV agents, antioxidants can ensure lasting bright color seat, within five years to ensure that no obviously fading, discoloration and surface cracking phenomenon. Testing based on ASTM G 154 Cycle 1 3-year 5-year stability stability 8-year stability test results Zone C = 1150Hrs YES = 1950Hrs YES = 3000 Hrs YES Third, the flame retardant properties of the seats with special brominated flame retardants, Great Lakes BA-59P, by vertical combustion test method, to the FV-1 level requirements GB / T2408-1996; level after burning test method can be achieved in the FH-2 class requirements GB / T2408-1996. Fourth, the antistatic properties of the seat of high density polyethylene (HDPE) raw materials add special antistatic agent, significantly reducing plastic surface resistance to reach 108 ~ 109Ω, reduce dust accumulation to improve cleanliness, efficient and long-lasting anti-static properties perfectly suited used in the northern dry climate.
