Abstract

A vehicle occupant protection system (10) includes a seat belt buckle (12) for receiving a seat belt tongue (16). A Hall effect device (62) is mounted on the seat belt buckle (12). The Hall effect device (62) has at least one electrical lead (72, 74). A magnet (68) is mounted on the seat belt buckle (12). The magnet (68) and the Hall effect device (62) are moveable relative to each other to first relative positions upon receipt of the seat belt tongue (16) in the seat belt buckle (12). The Hall effect device (62) provides a signal in response to the magnet (68) and the Hall effect device (62) being moved to the first relative positions. An electrical conductor (92, 94) has an electrical connection (110, 114) with the electrical lead (72, 74). The electrical connection (110, 114) is provided by melted portions (112, 116) of the electrical lead (72, 74) and the electrical conductor (92, 94) that are bonded together.

Claims

1. A vehicle occupant protection system comprising:

a seat belt buckle for receiving a seat belt tongue;

a Hall effect device mounted on said seat belt buckle, said Hall effect device having at least one electrical lead;

a magnet mounted on said seat belt buckle, said magnet and said Hall effect device being moveable relative to each other to first relative positions upon receipt of said seat belt tongue in said seat belt buckle, said Hall effect device providing a signal in response to said magnet and said Hall effect device being moved to said first relative positions; and

an electrical conductor having an electrical connection with said electrical lead, said electrical connection being provided by melted portions of said at least one electrical lead and said electrical conductor that are bonded together.

2. The vehicle occupant protection system of claim 1, wherein said electrical connection is formed by resistance welding said portions of said electrical conductor to said portions of said at least one electrical lead.

3. The vehicle occupant protection system of claim 1, wherein said electrical conductor comprises a wire.

4. A vehicle occupant protection system comprising:

a vehicle occupant protection device having a base part;

at least one electrical component mounted on said base part, each of said at least one electrical component having at least one electrical lead;

an electrical conductor having an electrical connection with said at least one electrical lead, said electrical connection being provided by melted portions of said at least one electrical lead and said electrical conductor that are bonded together,

said vehicle occupant protection device further comprising a seat belt buckle for receiving a seat belt tongue and said at least one electrical component further comprising a Hall effect device mounted on said seat belt buckle, said electrical connection electrically connecting said Hall effect device to said electrical conductor.

5. The vehicle occupant protection system of claim 4, further comprising a magnet mounted on said seat belt buckle, said magnet and said Hall effect device being moveable relative to each other to first relative positions upon receipt of said seat belt tongue in said seat belt buckle, said Hall effect device providing a signal in response to said magnet and said Hall effect device being moved to said first relative positions.

6. A vehicle occupant protection system comprising:

a vehicle occupant protection device having a base part;

at least one electrical component mounted on said base part, each of said at least one electrical component having at least one electrical lead;

an electrical conductor having an electrical connection with said at least one electrical lead, said electrical connection being provided by melted portions of said at least one electrical lead and said electrical conductor that are bonded together,

said vehicle occupant protection device further comprising a seat belt buckle for receiving a seat belt tongue and said at least one electrical component further comprising a Hall effect device mounted on said seat belt buckle and a capacitor mounted on said seat belt buckle, said electrical connection electrically connecting said Hall effect device and said capacitor to said electrical conductor.

7. The vehicle occupant protection system of claim 6, further comprising a magnet mounted on said seat belt buckle, said magnet and said Hall effect device being moveable relative to each other to first relative positions upon receipt of said seat belt tongue in said seat belt buckle, said Hall effect device providing a signal in response to said magnet and said Hall effect device being moved to said first relative positions.
