Abstract
An ejector element with a trigger for a belt buckle sensor includes a plate-shaped ejector body and a trigger blade of a magnetic and/or metallic material for producing a change in a magnetic field of a Hall sensor or an inductive sensor. The ejector element is distinguished by the fact that the trigger blade is connected in one piece to the ejector body, wherein the one-piece connection between the trigger blade and the ejector body is produced by an injection-molding process.
Claims4
An ejector element with a trigger for a belt buckle sensor comprising
- a plate-shaped ejector body and
- a trigger blade of a magnetic and/or metallic material for producing a change in a magnetic field of a Hall sensor or an inductive sensor,
- wherein the trigger blade is connected in one piece to the ejector body, and wherein the one-piece connection between the trigger blade and the ejector body is produced by a multi-component injection-molding process;
- wherein an entirety of the trigger blade is formed from a first plastic that is a magnetic and/or metallic polymer/plastic and the ejector body is formed from a further plastic, wherein the trigger blade and the ejector body are a common molded structure such that the one-piece connection between the trigger blade and the ejector body is a molded connection between the first plastic and the further plastic.
A method for producing an ejector element with a trigger for a belt buckle sensor, comprising the following steps
- injecting a magnetic and/or metallic polymer/plastic, forming a trigger blade, into a cavity of a multi-component injection-molding machine,
- injecting a further plastic, forming an ejector body, into the cavity, so that a one-piece connection between the trigger blade and the ejector body is produced by a multi-component injection-molding process, wherein:
- the magnetic and/or metallic polymer/plastic forming the trigger blade and the further plastic forming the ejector body are injected into the cavity one after the other according to a multi-component injection molding or sandwich process, wherein first the magnetic and/or metallic polymer/plastic forming the trigger blade-is injected into the cavity and then the further plastic forming the ejector body is injected into the cavity, or vice versa, or
- the magnetic and/or metallic polymer/plastic forming the trigger blade and the further plastic forming the ejector body are injected into the cavity simultaneously, so that the ejector element is produced according to a co-injection process.
