Problems solved by technology

On the other hand, this system has in particular the following disadvantage: the energy conductors (here electrical conductors) in the branches of the steering wheel (which supply the energy consumption) need to be positioned in order to guarantee that said conductors are not located in aggregates which are subsequently injected around the metal structure. surface level
This positioning achieved by the metal part between the hub and the rim on the one hand increases the finished product of the metal part and on the other hand limits the number of conductors from the hub to the rim due to space reasons

Embodiment Construction

[0025] specific implementation plan

[0026] figure 1 A vehicle steering wheel according to the invention is shown. The steering wheel comprises four branches ( 10 , 20 , 30 and 35 ) connecting a central hub 40 to a rim 50 forming a support for the driver of the vehicle.

[0027] The hub 40 comprises a metal part 41 comprising a hole 42 for securing an interface to a steering rod (not shown).

[0028] In order to give it good mechanical resistance, the rim 50 comprises a metal core. This metal core is connected to said hub 40 by means of two mechanical connections (which are metal pieces) immersed in each of said branches 10 and 20 (also referred to as first branches). Thus, the rim 50 is properly attached to the hub 40 and positioned accurately relative to the hub 40, so that the branches 30 and 35 (also referred to as second branches) do not have to be between the rim 50 and the A mechanical connection is included between the hubs 40, since the stiffness is sufficient. ...

Abstract

The invention relates to a vehicle steering wheel comprising: - a metal hub, - a rim, - at least one branch comprising a mechanical connecting piece securing the rim to the hub, characterized in that it comprises at least one other branch made from injected polymer between the hub and the rim, with no mechanical connecting piece securing the rim to the hub, and containing at least one energy conductor, the steering wheel comprising positioning means arranged to position said at least one energy conductor before the polymer of said branch is injected so as to guarantee a minimum distance between said at least one energy conductor and a surface of the polymer once injected.

Description

technical field [0001] The present invention generally relates to a steering wheel intended to be installed in a vehicle, and in particular to a steering wheel which proposes a function requiring energy supply at the level of the rim. Background technique [0002] A vehicle steering wheel with energy dissipation in its rim is known from the prior art, for example as described in WO2010113551A1. On the other hand, this system has in particular the following disadvantage: the energy conductors (here electrical conductors) in the branches of the steering wheel (which supply the energy consumption) need to be positioned in order to guarantee that said conductors are not located in aggregates which are subsequently injected around the metal structure. the surface level of the object. This positioning achieved by the metal part between the hub and the rim increases the finished product of the metal part on the one hand and limits the number of conductors from the hub to the rim o...
