ABSTRACT:
A ladder for use with vehicles is composed of two flexible supporting members and a number of foot steps, said supporting members comprising a reinforcement located in the vicinity of that face of the member which is directed outwardly from the vehicle so as to give said member a greater resistance to bending in the direction of the vehicle than in the opposite direction. According to another aspect of the invention each foot step at the opposite ends thereof is pivotally connected to brackets mounted in the flexible supporting members.
