The disclosed subject matter of the present application will now be described in more detail with reference to exemplary embodiments of the apparatus and method, given by way of example, and with reference to the accompanying drawings, in which:
A few inventive aspects of the disclosed embodiments are explained in detail below with reference to the various figures. Exemplary embodiments are described to illustrate the disclosed subject matter, not to limit its scope, which is defined by the claims. Those of ordinary skill in the art will recognize a number of equivalent variations of the various features provided in the description that follows.
Known arrangements of grab bars, as well as components associated with grab bars, have deficiencies. For example, a front seat in front of the grab bar can deflect toward the grab bar during operation of the vehicle. As a result, the front seat can come into contact with the fingers of a passenger grasping the grab bar while seated in a rear seat that is behind the front seat and the grab bar. A wire form bar can be connected to the grab bar to extend between the front seat and the grab bar and can a form a space between the wire form bar and the grab for the fingers of the rear seat passenger. As a result, the wire form bar can block the front seat before the front seat can impact the fingers of the rear seat passengers while grasping the grab bar. However, the rear seat passenger can mistakenly grasp the wire form bar instead of the grab bar. Thus, the front seat can impact the fingers of the rear seat passenger. Accordingly, it is desirable to provide a rear seat passenger with further protection against an impact between the front seat and the fingers of the rear seat passenger while grasping the grab bar.
