Abstract
A window lifter for a motor vehicle contains a plastic component and a metal component. The plastic component is at least in sections in mechanical contact with the metal component on a bearing surface, and wherein microcapsules are embedded into the plastic material of the plastic component at least in the region of the bearing surface. The microcapsules are filled with a lubricant.
Claims14
A window lifter for a motor vehicle, comprising:
- a metal component;
- and
- a plastic component having a contact surface, said plastic component being at least partially in mechanical touching contact with said metal component on said contact surface, and said plastic component having microcapsules filled with a lubricant being embedded in a plastic material of said plastics component at least in a region of said contact surface, said microcapsules constructed with different geometric properties for opening said microcapsules at different instances based upon mechanical loading thereon.
A method of forming a window lifter, which comprises the steps of:
- providing a metal component;
- and
- distributing microcapsules filled with a lubricant in a granulated plastic, the microcapsules constructed with different geometric properties for opening the microcapsules at different instances based upon mechanical loading thereon;
- and
- producing a plastic component from the granulated plastic for the window lifter, the plastic component having a contact surface and being at least partially in mechanical touching contact with the metal component on the contact surface, and the plastic component having the microcapsules filled with the lubricant being embedded in the granulated plastic of said plastic component at least in a region of the contact surface.
