Abstract

A passive seat belt system includes a seat belt buckle of a receptacle device having a connecting switch member connected to a battery of a vehicle and a tongue of a webbing so that the vehicle can be actuated or not in response to fastening or unfastening of a seat occupant.

Claims

1. A passive seat belt system including a seat belt buckle device of a fixed belt and a tongue of a restraining webbing for being adapted to be engaged with the seat belt buckle device, said passive seat belt system comprising:

a housing defining said seat belt buckle device, said housing including;

a tongue inserting hole for slidably receiving a tip of said tongue,

a pressing plate for engaging said tongue with or releasing said tongue from an engagement aperture,

a moving member having a raised portion extending from the top portion of said moving member,

a movable operating rod operatively connected to said moving member for movement to a first position and to a second position,

a first resilient spring operatively connected to an attaching plate and a contacting terminal and the movable operating rod,

a second resilient spring operatively connected to the raised portion and the movable operating rod,

a connecting switch box containing said attaching plate, said first resilient spring connected to said connecting switch box and one side of said attaching plate, said contacting terminal attached to the other side of said attaching plate for fixing to said movable operating rod, and a pair of conducting terminals attached to the interior of said connecting switch box for operatively associating with said contacting terminal,

a key box including a starting terminal and a driving terminal for receiving a vehicle key,

a starting relay operatively connected to the key box, including a first connecting switch and connected to an engine of a vehicle, and

a running relay including a second connecting switch and connected to said driving terminal and a battery, so that when said operating rod is in said first position said contacting terminal connects to said pair of conducting terminals the vehicle cannot be started and when said operating rod is in said second position said contacting terminal is disengaged from said pair of conducting terminals the vehicle can be started.

2. The passive seat belt system of claim 1, wherein the first connecting switch contains two terminals so as to connect to the engine of the vehicle for its ignition when the seat occupant fastens the seat belt or disconnect to the engine of the vehicle for its deactivation when the seat occupant unfastens the seat belt.

3. The passive seat belt system of claim 1, wherein the second connecting switch contains two terminals so as to connect to the battery for driving the vehicle when the seat occupant fastens the seat belt or disconnect to the battery for stopping the vehicle when the seat occupant unfastens the seat belt.
