Abstract
An electronic unit defines an interior and includes a circuit card assembly disposed in the interior. An enclosure surrounds five sides of the interior. A sixth side of the interior is closed by a circuit card assembly. The circuit card assembly is coated with a metal layer configured to contain flame within the interior.
Claims20
An assembly comprising:
- an electronic unit having a front unit defining an interior and having a rear unit containing electronic devices, the electronic unit including:
- a bezel extending around and closing four sides of the interior, the bezel defining a front opening to the interior and a rear opening to the interior;
- a circuit card assembly extending across the rear opening and engaging the bezel at each of the four sides to close the rear opening;
- and
- a visual display panel extending across the front opening and engaging the bezel at each of the four sides, the visual display panel closing the front opening, the visual display panel including a flame resistant material,
- wherein the circuit card assembly is coated with a metal layer configured to contain flame within the interior,
- wherein the interior is contained by the bezel, the circuit card assembly and the visual display panel as a flame resistant unit separated from the rear unit by the circuit card assembly.

A visual display assembly for an instrument panel, the assembly comprising:
- a front unit defining a first interior and including:
- a visual display panel with a transparent substantially non-flammable surface disposed on a first side of the visual display panel;
- a circuit card assembly disposed on a second side of the visual display panel;
- and
- a bezel surrounding four sides of the visual display panel, the bezel defining a front opening to the interior and a rear opening to the interior, the visual display panel closing the front opening and the circuit card assembly closing the rear opening;
- and
- a rear unit defining a second interior and including:
- a case with five substantially closed sides and an open side that faces the front unit;
- and
- electronic devices contained in the second interior and coupled with the circuit card assembly;
- wherein the front and rear units are disposed adjacent each other, with the circuit card assembly facing the open side, the circuit card assembly separating the first interior from the second interior, the circuit card assembly coated with a metal layer to inhibit flame propagation between the first and second interiors and to contain flame within the first interior.

A visual display assembly for an instrument panel, the assembly comprising:
- a front unit defining a first interior containing flammable internal componentry and including:
- a visual display panel with a transparent substantially non-flammable layer disposed on a first side of the visual display panel that has a surface facing out of the instrument panel;
- a circuit card assembly disposed on a second side of the visual display panel that is opposite the first side;
- and
- a bezel surrounding four sides of the visual display panel, the bezel defining a front opening to the first interior and a rear opening to the first interior, the visual display panel closing the front opening and the circuit card assembly engaging the bezel at each of the four sides and closing the rear opening;
- and
- a rear unit defining a second interior and including:
- a case with four substantially closed sides and an open side that faces the front unit, the four substantially closed sides of the case engaging the bezel;
- and
- electronic devices contained in the second interior and coupled with the circuit card assembly;
- wherein the front and rear units are connected together, with the circuit card assembly having a metal layer that closes the open side and the rear opening, the circuit card assembly separating the first interior from the second interior, the metal layer configured to inhibit flame propagation between the first and second interiors and to contain flame within the first interior.
