Abstract
Abstract A passenger conveyance, such as a motor vehicle, a boat, an airplane or the like has walls which enclose and define a passenger compartment. A roof structure is provided on the passenger compartment. An arrangement for establishing within the passenger compartment an electrostatic field is provided and includes first electrode means which is remote from the roof structure, and second electrode means including an electrically conductive element and an electrically insulating element which insulates the conductive element from the remainder of the wall means. At least one of these elements constitutes at least a portion of the roof structure of the conveyance.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
125 words
In a passenger conveyance of the type having wall means enclosing and defining a passenger compartment provided with a roof structure, at least part of said wall means being electrically conductive, an arrangement for establishing within the passenger compartment an electrostatic field, said arrangement comprising first electrode means remote from said roof structure, second electrode means, including an electrically conductive element and an electrically insulating element insulating said electrically conductive element from the electrically conductive part of said wall means, at least one of said elements constituting at least a portion of said roof structure, and a source of electrical energy having two poles of opposite polarity respectively connected to said first electrode means and to said electrically conductive element of said second electrode means.
Claim 2
Dependent Claim
125 words
In a passenger conveyance of the type having wall means enclosing and defining a passenger compartment provided with a roof structure, at least part of said wall means being electrically conductive, an arrangement for establishing within the passenger compartment an electrostatic field, said arrangement comprising first electrode means remote from said roof structure, second electrode means, including an electrically conductive element and an electrically insulating element insulating said electrically conductive element from the electrically conductive part of said wall means, at least one of said elements constituting at least a portion of said roof structure, and a source of electrical energy having two poles of opposite polarity respectively connected to said first electrode means and to said electrically conductive element of said second electrode means.
Claim 3
Dependent Claim
