A steering wheel and column assembly for a vehicle includes a steering column housing and a steering column shaft rotatably coupled to the steering column housing. A steering wheel includes a central hub coupled to the steering column shaft and a steering wheel rim connected to the central hub by one or more spokes extending radially from the central hub. A dampening system cooperates with the steering wheel and includes at least one mass damper body disposed adjacent to central hub. One or more vibration damping elements extend at least partially through the at least one mass damper body and the central hub. One or more resilient support members cooperate with the at least one mass damper body, central hub and the one or more vibration damping elements to absorb vibrations in the steering wheel and column assembly.

The present invention is directed to systems for providing a pathway for at least one electrical conductor to supply current from a vehicle or marine craft power source to a steering wheel comprising at least one working element for heating or controls. The present invention utilizes a clock spring assembly inside a channel created by a housing mount and a housing base and encased in a housing cover for infinite rotation of the steering wheel while still maintaining a path for current to travel through the clock spring to the wheel.

A vehicle includes a steering wheel support assembly that includes a trim component that defines a trough. The vehicle further includes a steering wheel operably coupled to the steering wheel support assembly and operable to pivot about a first axis from a steering wheel use position to a steering wheel stowed position. In the steering wheel use position, the steering wheel is operable to rotate about a second axis to steer the vehicle. In the steering wheel stowed position, a portion of the steering wheel is received within the trough defined by the trim component.

A steering wheel includes: a hub; a rim connected to the hub through a plurality of spokes; and a first steering wheel remote control and a second steering wheel remote control arranged on sides of the hub, respectively, in a symmetric manner. A biological parameter measuring apparatus includes: a first conductive bezel arranged around the first steering wheel remote control; a second conductive bezel arranged around the second steering wheel remote control; and a signal processor, which is electrically connected to the first and second conductive bezels, configured to process and calculate a biological parameter based on a signal detected by at least one of the first conductive bezel or the second conductive bezels. The first conductive bezel is spaced apart from the second conductive bezel.

The invention aims at providing a work vehicle in which an operator can easily view each of switches in spite of the work vehicle in which a plurality of switches such as a DPF regeneration switch, a working switch and a one-touch automatic switch are concentrically provided on a front surface of a control seat. In a work vehicle having a cabin which is inward provided with a control seat installed in a travel machine body, a DPF regeneration switch, a working switch, and a one-touch automatic switch are provided. The DPF regeneration switch is provided on an upper surface of a steering column in a base portion of a control steering wheel, and the DPF regeneration switch is arranged in a field of vision of an operator under a straight moving work posture.

A steering apparatus for use in steering a vehicle includes: a movable body to which an input device is attached, the movable body configured to move back and forth in an extend-retract direction between a first position closer to the front of the vehicle and a second position closer to the driver; an intermediate guide that guides the movable body in the extend-retract direction, and moves back and forth in the extend-retract direction; a base guide that is attached to the vehicle and guides the intermediate guide in the extend-retract direction; a first extend-retract mechanism including an extend-retract drive source that causes the intermediate guide to move back and forth relative to the base guide; and a second extend-retract mechanism that causes the movable body to move back and forth relative to the intermediate guide by using driving force of the extend-retract drive source.

A steering wheel for vehicle having a steering column includes a steering wheel main body and a horn control assembly. The steering wheel main body includes a pressing portion, a handle and at least one connection portion. The handle is disposed around the pressing portion. The connection portion connects the handle to the pressing portion. The horn control assembly includes a pressure sensing module, a control module and a horn. The pressure sensing module is disposed at the pressing portion for sensing the pressed status of the pressing portion and outputting a pressure sensing signal. The control module is configured to have preset pressure ranges and connected to the pressure sensing module. The preset pressure ranges correspond to multiple volume levels of the horn. The control module receives the pressure sensing signal and compares it with the preset pressure ranges to control the volume of the horn to sound.
