Door handle for a car, and method for producing a door handle

Abstract

The invention relates to a door handle for a car, wherein the door handle has a handle section to be gripped manually and a pivoting bearing section, by way of which the door handle can be mounted on a car door such that it can be pivoted about a pivot axis between a closed position and an open position which unlocks the car door, wherein a metal ball, in particular a steel ball, or a metal cylinder, in particular a steel cylinder, is fastened to the door handle, wherein, if a predefined transverse acceleration which acts on the door handle occurs, the metal ball or the metal cylinder counteracts, as a counterweight, an opening force which acts on the handle section on account of the transverse acceleration. Moreover, the invention relates to a corresponding method for producing a door handle.

1 . A door handle for a car, wherein the door handle has a handle section to be gripped manually and a pivoting bearing section, by way of which the door handle can be mounted on a car door such that it can be pivoted about a pivot axis between a closed position and an open position which unlocks the car door, wherein a metal ball, in particular a steel ball, or a metal cylinder, in particular a steel cylinder, is fastened to the door handle, wherein, if a predefined transverse acceleration which acts on the door handle occurs, the metal ball or the steel cylinder counteracts, as a counterweight, an opening force which acts on the handle section on account of the transverse acceleration. 
     
     
         2 . The door handle as claimed in  claim 1 , wherein the center of mass of the door handle with the metal ball which is fastened thereto or the metal cylinder which is fastened thereto lies in the region of the pivoting bearing section, in particular substantially in the pivot axis of the door handle. 
     
     
         3 . The door handle as claimed in  claim 1 , wherein the metal ball or the metal cylinder is molded at least in sections into the door handle in the context of a plastic injection molding process for producing the door handle. 
     
     
         4 . The door handle as claimed in  claim 1 , wherein the metal ball or the metal cylinder is held in a latching manner in a latching receptacle of the door handle. 
     
     
         5 . The door handle as claimed in  claim 4 , wherein the latching receptacle has a plurality of elastic latching arms which hold the metal ball or the metal cylinder. 
     
     
         6 . The door handle as claimed in  claim 1 , wherein the metal ball or the metal cylinder is held by way of a force fit in a force-fit receptacle of the door handle. 
     
     
         7 . The door handle as claimed in  claim 1 , wherein after the fastening of the metal ball or the metal cylinder, the door handle with the metal ball fastened thereto or the metal cylinder fastened thereto has been coated, in particular has been coated galvanically, furthermore has been chrome-plated, in particular. 
     
     
         8 . A car door, comprising a door handle as claimed in  claim 1  which is mounted pivotably thereon. 
     
     
         9 . A method for producing a door handle as claimed in  claim 1 , comprising the steps:
 provision of a plastic injection mould with a mould cavity which represents the door handle,   automatic feeding and holding of a metal ball or a metal cylinder in a predefined position in the mould cavity,   injection of a plasticized plastic into the mould cavity, wherein the plasticized plastic flows at least in sections around the metal ball which is held in the predefined position or around the metal cylinder which is held in the predefined position,   opening of the plastic injection mould after a curing time and removal of the door handle with the metal ball which is molded at least in sections into said door handle or the metal cylinder which is molded at least in sections into said door handle.   
     
     
         10 . The method as claimed in  claim 9 , wherein the plastic injection mould has a slide which delimits the mould cavity in sections and can be moved in the longitudinal direction within a cavity, wherein the metal ball or the metal cylinder falls into the cavity when the slide is withdrawn from the mould cavity, and wherein the metal ball or the metal cylinder is subsequently conveyed by a movement of the slide in the longitudinal direction within the cavity along a conveying path into the predefined position in the mould cavity. 
     
     
         11 . The method as claimed in  claim 10 , wherein the cavity is formed by a hollow slide which surrounds the slide at least in sections and can be moved in the longitudinal direction independently of the slide, wherein the metal ball or the metal cylinder falls into the cavity when the slide is withdrawn from the hollow slide, wherein the metal ball or the metal cylinder is subsequently conveyed by a movement of the slide in the longitudinal direction within the hollow slide along the conveying path into the predefined position in the mould cavity. 
     
     
         12 . The method as claimed in  claim 10 , wherein a further slide which can be moved in the longitudinal direction is provided, which slide, in a position which is moved into the mould cavity, forms a stop for holding the metal ball or the metal cylinder in the predefined position. 
     
     
         13 . The method as claimed in  claim 9 , wherein a blocking pin which is mounted such that it can be displaced in its longitudinal direction is provided, which blocking pin is prestressed into a blocking position which protrudes in sections into the conveying path of the metal ball or the metal cylinder, wherein the metal ball or the metal cylinder presses the blocking pin, during the conveying along its conveying path into its predefined position in the mould cavity, out of its blocking position into a release position which releases the conveying path of the metal ball or the metal cylinder. 
     
     
         14 . The method as claimed in  claim 9 , wherein the door handle with the metal ball which is molded at least in sections into said door handle or the metal cylinder which is molded at least in sections into said door handle is coated galvanically, in particular is chrome-plated, after the removal from the plastic injection mould. 
     
     
         15 . The method as claimed in  claim 9 , wherein, after the removal from the plastic injection mould and optionally after coating, in particular galvanic coating, furthermore chrome-plating, in particular, the door handle with the metal ball which is molded at least in sections into said door handle or the metal cylinder which is molded at least in sections into said door handle is mounted pivotably by way of its pivoting bearing section on a car door.
