Composites, including the laminate, and preferably a metal article, most preferably a rail for use in an electric transit system, are formed by bonding the laminate to the metal article using a suitable bonding agent such as a rubber to metal adhesive. In a preferred embodiment, the unvulcanized laminate is applied or connected to the metal article prior to vulcanization. Rubber clad rail assemblies having a closed cell rubber foam layer and methods for preparing the same are disclosed.

Abstract: The invention relates to a roll-bar system for vehicles comprising a roof, which can be retracted and raised in a motor-driven manner by a roof-displacement mechanism. The system consists of a roll-bar body that is associated with each seat and does not comprise a sensor-controlled crash drive. The body can be forcibly displaced autonomously, in conjunction with the roof-displacement mechanism, between a first rigid position, when the roof is closed, and a second raised, rigid position, when the roof is open. The aim of the invention is to raise the rigid roll-bar system into the respective rigid positions in a kinematically simple, forcibly guided manner.
