1、 Main functions:

This machine is suitable for testing the front end stability of seats (such as chairs and office chairs).

2、 Test principle:

Place the sample on the test bench, block the front foot with a cushion block, and then apply a certain load on the seat. At the same time, apply a force of 20N before the loading point to check whether the sample is tilted forward to evaluate the forward stability of the sample.

3、 Technical parameters:

1. Maximum load of seat: 600 N, cumulative; Tensile force 20 N

2. Loading point position: seat center position, 60 mm from the front edge

3. Size of seat loading pad: diameter 200 mm, arc r300 mm

4. Loading rod: diameter 19 mm; Both ends: type A, spherical SR19 mm; Type B, 45 degrees sharp

5. Lifting method of weight basket: manual control

6. Air source: 6 kgf/cm ^ 2 or more stable air source (provided by the user)

7. Overall dimension: 1800 * 1000 * 80 (mm) (length * width * height)

8. Weight: about 150 kg

4、 Reference standards: EN581-1/- 2/- 3, EN 1022, EN 1729-2, ANSI/BIFMA X5.1, etc.
