摘要

Improvements introduced in the tilting of the bed bases on the beds, characterized in that by means of them a base is reached that tilts and is raised automatically or mechanically adopting an angular position on the bed, due to the competition of a torsion bar, which offers a central stretch from which they start, perpendicularly, two lateral ones, which present, one with respect to the other, a certain angular position, when the torsion bar is not subjected to any tension, *** see image (Machine-translation by Google Translate, not legally binding)
