One application I have been asked about for the rotary viscous damper is in the furniture industry, industrial, commercial or residential. Overheard bins for file cabinets, movable work surfaces, seating or ergonomic applications where slamming of lids or furniture components need to be turned into a slow close member. The slow close feature can dramatically improve the safety situation. No more pinched body parts or loud, distracting noises. An office chair that pops back to vertical position a little too quickly can be a good application for a rotary viscous damper. Head rests can also be a good application for a friction hinge to adjust the angle relative to the back of your head.
