Patent Images
1. A chassis for an electrical component configured to be installed in a motor vehicle, comprising:
- an integral central portion having vertical side walls, wherein the vertical side walls have upper edges defining an upper opening on a first side of the vertical side walls and lower edges defining a lower opening on a second side of the vertical side walls opposite to the first side;
a horizontal upper portion disposed across the upper opening of the central portion at the first side of the vertical side walls and a horizontal lower portion disposed across the lower opening of the central portion at the second side of the vertical side walls;
the upper portion being associated with the vertical side walls of the central portion by the use of a first tab and a first tab receiving portion;
the lower portion being associated with the vertical side walls of the central portion by the use of a second tab and a second tab receiving portion; and
wherein the first tab receiving portion is substantially flexible and deflects when engaging the first tab and wherein the second tab receiving portion is substantially flexible and deflects when engaging the second tab.

9. A chassis for an electrical component configured to be installed in a motor vehicle, comprising:
-
a central portion, a lower portion and an upper portion; the central portion, the lower portion and the upper portions being made of a conductive plastic; wherein the central portion comprises a plurality of vertical side walls enclosing an interior volume, wherein upper edges of the vertical side walls define a horizontally extending upper opening on a first side of the vertical side walls, and wherein lower edges of the vertical side walls define a horizontally extending lower opening on a second side of the vertical side walls opposite to the first side; wherein the upper portion extends horizontally across the upper opening at the first side of the vertical side walls and the lower portion extends horizontally across the lower opening at the second side of the vertical side walls; wherein the upper portion and the lower portion are attached to the central portion by pressing the upper portion and the lower portion against the central portion in a direction substantially perpendicular to the upper portion and the lower portion; wherein the central portion includes one of a first tab and a first tab receiving portion and the upper portion includes the other of the first tab and the first tab receiving portion and wherein the central portion includes one of a second tab and a second tab receiving portion and the lower portion includes the other of the second tab and the second tab receiving portion; and wherein the first tab receiving portion is substantially flexible and deflects when engaging the first tab and wherein the second tab receiving portion is substantially flexible and deflects when engaging the second tab. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of assembling a chassis for an electrical component configured to be installed in a motor vehicle, comprising the steps of:
-
associating a central portion of the chassis with an upper portion of the chassis, the central portion comprising a plurality of side walls enclosing an interior volume configured to receive an electrical component, the side walls having upper edges defining an upper opening on a first side of the side walls and lower edges defining a lower opening on a second side of the side walls opposite to the first side; covering the upper opening of the central portion with the upper portion of the chassis, the upper portion extending perpendicularly to the side walls at the first side of the side walls;
covering the lower opening of the central portion with a lower portion of the chassis, the lower portion extending perpendicularly to the side walls at the second side of the side walls;
pressing a first tab receiving portion of one of the upper portion and the central portion over a first tab of the other of the upper portion and the central portion;
pressing a second tab receiving portion of one of the lower portion and the central portion over a second tab of the other of the lower portion and the central portion; and
thereby connecting the upper portion and the lower portion to the central portion. - View Dependent Claims (22, 23, 24, 25)
