KW-BFM-10-01 Chair Backrest Tester (Back pulling)
| Working Rationale | 1 Imitate human body sit in a chair and lean back action to test the back performance. | ||||
| 2 Place 250lbs 16 dia sand bag in the seat,apply a force that is initially 90 degrees ± 10 degrees to the plane of the backrest. | |||||
| 3 Record the testing cycle, evaluate the product performance. | |||||
| Structure Characteristics | 1 Multi-function testing equipment, out-force and traveling for selection. | ||||
| 2 Through change the position of Pulley to change out-force direction of air cylinder. | |||||
| 3 The form-fitting Device was fasten to backrest which was connect to the air cylinder by Ribbon. When the force was lost, the backrest will return to the original state. | |||||
| 4 Precision manual pressure regulating valve ensure to get the stable and reliable out-force value which indicate in the digital display. | |||||
