The ejection element includes: a sheet-like ejector main body; and a trigger piece made of a magnetic and/or metallic material for causing a change in the magnetic field of the hall sensor or the inductive sensor. The ejection element is characterized in that: the trigger piece is connected to the ejector body in one piece, wherein the one-piece connection between the trigger piece and the ejector body is established by an injection molding process.)

1. A trigger-equipped ejection element for a seat belt buckle sensor, the ejection element comprising:

a sheet-like ejector main body; and

a trigger piece made of a magnetic and/or metallic material for causing a change in the magnetic field of the Hall sensor or inductive sensor,

it is characterized in that the preparation method is characterized in that,

the trigger piece is connected to the ejector body in a single piece, and wherein the single piece connection between the trigger piece and the ejector body is established by an injection molding process.

2. The ejection element according to claim 1,

it is characterized in that the preparation method is characterized in that,

the trigger piece is made of a magnetic and/or metallic polymer/plastic and the ejector body is made of plastic, and wherein the one-piece connection between the trigger piece and the ejector body is established by a multicomponent injection molding process.

3. The ejection element according to claim 2,

it is characterized in that the preparation method is characterized in that,

the ejector body is made of POM.

4. The ejection element according to claim 1,

it is characterized in that the preparation method is characterized in that,

said trigger plate has a magnetic and/or metallic element, and wherein said ejector element is manufactured by coating said magnetic and/or metallic element with plastic, such that said trigger plate and said ejector body are manufactured in one piece by an injection moulding process.

5. The ejection element according to claim 1,

it is characterized in that the preparation method is characterized in that,

the ejection element is made of POM.

6. A seat belt buckle comprising:

a hall sensor or an induction sensor for detecting a locked state of the buckle,

the ejection element according to any one of claims 1 to 5, displaceable by a belt tongue, for changing the magnetic field of a hall sensor or an inductive sensor for detecting the locked state of the belt buckle.

7. A method for manufacturing the ejection element with trigger for a buckle sensor according to any one of claims 1 to 3, comprising the steps of:

the magnetic and/or metallic polymer/plastic from which the trigger piece is made is injected into the cavity of a multi-component injection molding machine,

injecting another plastic material into the cavity from which the ejector body is made, such that a one-piece connection between the trigger piece and the ejector body is established by a multicomponent injection molding process, wherein

According to a "multi-component injection molding or sandwich process", the magnetic and/or metallic polymer/plastic from which the trigger piece is made and the plastic from which the ejector body is made are injected into the cavity in sequence, wherein the magnetic and/or metallic polymer/plastic from which the trigger piece is made is first injected into the cavity and the plastic from which the ejector body is made is subsequently injected into the cavity, or the order is reversed, or wherein

The magnetic and/or metallic polymer/plastic from which the trigger piece is made is injected into the mould cavity simultaneously with the plastic from which the ejector body is made, so that the ejector element is manufactured according to a co-injection moulding process.

8. A method for manufacturing the ejection element with trigger for a seat belt buckle sensor according to claim 1 and any one of claims 3 to 4, the method comprising the steps of:

placing a magnetic and/or metallic element for the trigger piece into a cavity of an injection molding machine,

injecting the plastic into the cavity of the mold,

whereby the trigger piece and the ejector body are manufactured by an injection molding process.
