Procede de fabrication d'une pedale creuse bi-matiere et pedale correspondante

Abstract

The invention relates to a pedal (1) comprising a lever (2) extending in a longitudinal direction (L) from a shoe (3) for receiving a control force (F) to an organ joint (4) to allow tilting of said pedal about a pivot axis (XX '), said pedal being characterized in that said lever (2) is formed by a hollow lever body (5) which divided transversely to the longitudinal direction, and preferably in a joint plane (PJ) horizontal, in a first half-shell (6) made of a first material and a second half-shell (7) made of a second material, preferably distinct from the first material, at least one of said first and second materials consisting predominantly, and preferably entirely, by a polymer or a polymer blend.

Description

technical field [0001] The present invention relates to the general field of controlling pedals, in order to equip a pedal assembly, such as a car pedal assembly, allowing the user, in particular the driver, to control any function, such as acceleration, clutching or braking. Background technique [0002] It is currently known, for example from document EP-0714056, that one-piece pedals are made of plastic material, depending on the injection molding process. [0003] In order to ensure their robustness, such pedals require a special constructional arrangement, especially in the presence of multiple ribs. [0004] However, such an arrangement tends to complicate the structure of the pedal and, as a consequence, the method of its manufacture, since said method must use injection molding tools, which are very specific, complex and relatively expensive, and especially when multiple core body. [0005] Furthermore, pedals made of known plastic materials are sometimes subjected...

Problems solved by technology

[0004] However, such an arrangement tends to complicate the structure of the pedal and, as a consequence, the method of its manufacture, since said method must use injection molding tools, which are very specific, complex and relatively expensive, and especially when multiple Core time

[0005] Furthermore, despite the above-mentioned structural arrangement, pedals made of known plastic materials are sometimes subjected to relatively high levels of stress and deformation
