Steering wheel with non-rotating airbag
First Claim
1. A steering wheel comprising an armature having a hub that is coupled to a vehicle steering shaft, the hub being provided with an opening, and non-rotating housing assembled with the hub on a side of the hub that will be proximal with a vehicle driver, and a coiled element that is a cylindrical helix arranged coaxially with the steering wheel shaft and extends through the opening in the hub to couple the non-rotating housing to a stationary component of the vehicle, the coiled element spiralling through the hub opening when the steering wheel is rotated, the non-rotating housing supporting an airbag module, and further comprising conductors for power or signals and wherein the coiled element is provided with a slot that conveys the conductors through the opening in the hub.

Abstract
The present invention relates to a steering wheel having a stationary hub mounted portion. The steering wheel has an armature with a hub and is coupled to a vehicle steering shaft. The hub is provided with an opening through which a coiled element passes. A non-rotating housing is assembled with the hub. The coiled element connects the non-rotating housing to a stationary component of the vehicle. The coiled element screwing or unscrewing itself to or from the hub via the opening when the steering wheel is rotated.
