Steering Section Layout With Offset Axis for More Driver Legroom

The patent changes the spatial arrangement from a conventional configuration where the handle-support shaft center axis coincides with the handle center axis of rotation, to an offset configuration where the handle-support shaft center axis is positioned above the handle center axis of rotation. This dimensional repositioning in the vertical direction creates additional leg space while preserving the steering function through the guide-roller mechanism.

The patent divides the rotating assembly into separate functional components: a fixed-side guide attached to the handle-support shaft, and a rotating-side guide attached to the handle, connected by rollers. This segmentation allows the handle to rotate independently about its own center axis while the handle-support shaft remains fixed, enabling the offset axis configuration that increases leg space.

The patent replaces the conventional mechanical rotational support where the handle-support shaft rotates with a guide-roller system. The fixed-side guide and rotating-side guide with rollers create a low-friction rotational interface that supports the handle's rotation while keeping the handle-support shaft fixed, achieving the desired leg space with a refined mechanical approach.

The patent introduces rollers as an intermediary element between the fixed-side guide and rotating-side guide. These rollers facilitate the rotational motion of the handle while the handle-support shaft remains fixed, acting as a mediator that enables rotation without requiring the support shaft itself to rotate, thus maintaining the offset axis configuration and increased leg space.
