A seat platform carrier for a chair tilts backward and forward relative to a base part when a load, such as a person sitting is the chair, is placed on the seat carrier. A resetting mechanism positioned the seat platform carrier to the same initial position when the load is removed. A lamellar pack attached to a hand lever provides the user with a means to lock the seat platform carrier in a desired tilted position. A height adjusting actuator is included in the base part to permit the user to select an appropriate seat platform height. A user sitting on the seat platform carrier is able to freely tilt forward or backwards. |
