Abstract

A vehicle, in particular for conveying people and/or freight, includes at least one fireproof electrical network, at least one first vehicle region having a first fire load, and at least one second vehicle region having a second fire load that is smaller than the first fire load. In order to keep the necessary fireproofing as low as possible, at least part of the fireproof electrical network is disposed in the second vehicle region.

First claim

The invention claimed is:

1. A vehicle for conveying at least one of people or freight, the vehicle comprising:
at least one first vehicle region having a first fire load, said at least one first vehicle region being configured for conveying people or freight;
at least one second vehicle region having a second fire load being smaller than said first fire load, said at least one second vehicle region not being configured for conveying people or freight, wherein said at least one first vehicle region is located above a floor of the vehicle and said at least one second vehicle region is located below the floor of the vehicle;
a fireproofing device including a fire-protective housing disposed in said at least one second vehicle region;
at least one fireproof electrical network, at least part of said at least one fireproof electrical network being disposed in said fire-protective housing; and
said fireproofing device including at least one circuit board disposed in said fire protective housing, said fireproofing device configured to function as a device selected from the group consisting of a fire alarm system, an emergency travel device for the vehicle, and a public information system; and
a network being external to said housing, said at least one fireproof electrical network including at least one plug connector for connecting said part of said at least one fireproof electrical network inside said housing to said network external to said housing;
said housing including a wall with said plug connector disposed therein, said at least one circuit board extending in a direction away from said wall of said housing.

2. The vehicle according to claim 1 , which further comprises a body of the vehicle forming at least one fireproof section in said at least one second vehicle region, at least part of said at least one fireproof electrical network being disposed in said at least one fireproof section.

3. The vehicle according to claim 1 , wherein said at least one fireproof electrical network includes a plurality of sub networks having different functionalities required in an event of a fire, all of said sub networks being disposed in said housing.

4. The vehicle according to claim 1 , wherein said at least one fireproof electrical network includes at least one switching element disposed on said at least one circuit board.

5. The vehicle according to claim 4 , wherein said at least one switching element is at least one relay.

6. A vehicle for conveying at least one of people or freight, the vehicle comprising:
at least one first vehicle region having a first fire load, said at least one first vehicle region being configured for conveying people or freight and being delimited by a component;
at least one second vehicle region having a second fire load being smaller than said first fire load, said at least one second vehicle region not being configured for conveying people or freight, wherein said at least one first vehicle region is located on one side of said component and said at least one second vehicle region is located on another side of said component;
a fireproofing device including a fire-protective housing disposed in said at least one second vehicle region;
at least one fireproof electrical network, at least part of said at least one fireproof electrical network being disposed in said fire-protective housing in said at least one second vehicle region;
said fireproofing device including at least one circuit board disposed therein, said fireproofing device configured to function as a device selected from the group consisting of a fire alarm system, an emergency travel device for the vehicle, and a public information system; and
a network being external to said housing, said at least one fireproof electrical network including at least one plug connector for connecting said part of said at least one fireproof electrical network inside said housing to said network external to said housing;

said housing including a wall with said plug connector disposed therein, said at least one circuit board extending in a direction away from said wall of said housing.
