PERFECCIONAMIENTOS EN LEVANTA-CRISTALES PARA VEHICULOS AUTO-MOVILES

摘要

In the illustrated window raiser, the window is raised or lowered by a motor which drives a screw engaged with a nut constituting a slide guided in a slideway by means of two symmetrical crossed arms. The arms are connected to the slideways at the base of the window and to two fixed center slideways and are connected to each other at their crossing point by an articulation carried by the nut. The articulation rigidly interconnects two semi-arms constituting one of the arms and disposed on each side of the other arm which is in a single piece. The two arms are capable of undergoing angular movements on each side of the axis of the articulation. A drive comprising a pinion and a rack cable may be substituted for the illustrated screw and nut mechanism.
