Abstract: A portable restraint device for a commuter to retain balance on a public transportation vehicle. The portable restraint device wraps a hook around a horizontal, vertical, or ring-shaped grab bar on the train or bus. The hook may be shaped like a hook, or operable as a carbiner, and is configured to adjust and securely attach to a variety of grab bars on public transportation vehicles. The opposite end of the portable restraint device includes a loop, configured for a hand to grip. The loop is often a flexible meshing material designed for comfort on long commutes. By gripping the loop, the commuter avoids contact with the grab bar surface, thereby avoiding germs. A handle secures the hook to the loop. However, the commuter is also able to grip the handle to retain balance. After the commute finishes, the commuter disengages the portable restraint device from the grab bar.

Abstract: The present invention relates to a supporting module for vehicle doors and a mounting procedure for said module, wherein said module incorporates the usual functional elements provided in vehicle doors and is meant to facilitate the mounting tasks. It incorporates an element meant to provide a sealing by covering one of the main openings of the inner plate of the door box, thereby separating the wet area and the dry area of the vehicle. The special configuration of the module and the openings of the inner plate of the door box facilitate the mounting and removal tasks of the module and the elements incorporated on the door, as well as the establishment of a sealing. In addition, the module is freed of all structural responsibilities.
