AntiShock AS: comfort and safety
The locking gas spring with the "AntiShock" module detects the load condition of the application and reacts accordingly. When used in an office chair with dynamic free-swinging, the Varilock with AntiSchock provides the user with a smooth moving action (comfort function). In addition, it will return the non-loaded backrest slowly from the reclined to the vertical position when released. Thus it will avoid the so-called catapult effect (safety function).
In the case of height-adjustable tables which have a low intrinsic weight but are subjected to high loads when in use (Varilock with a high extension force), the Varilock allows a quick height adjustment of the loaded table and, thanks to AntiShock, also prevents the tabletop rising up too quickly when the empty, unloaded table is released.
