<p>The car seat is supported on a base frame and support frame which are coupled together by two scissor frames formed by two intersecting scissor arms pivotally connected by a bolt. A support lever has at its free end a run-up face which acts on a support roller which is mounted on the base frame to move in the plane defined by the run-up face. The support lever is adapted to swivel together with pair of scissor arms out of the corresponding arms of the two scissor frames. The support roller is pressed by a support spring mounted on the same base frame against the run-up face.</p> |
