Abstract: Vehicle including a frame, a seat, a wheel, a drive sprocket arranged on the wheel, a main drive sprocket, a transmission member coupling the drive sprockets, a pedal slider arranged in front of the seat and which swings forward and rearward, and a drive mechanism including an overrunning clutch system connected to the main drive sprocket. A power link is connected at a first end region to the pedal slider and at a second end region to the clutch system. Forward movement of the pedal slider causes movement of the power link and rotation of the clutch system which causes movement of the main drive sprocket and the wheel drive sprocket resulting in rotation of the wheel. A roller is arranged on the frame to guide the power link in a substantially horizontal plane in a portion between the roller and the pedal slider.

Abstract: Poppet valve for an internal combustion engine including a valve stem and a single circular valve head attached at one end of the valve stem. The valve head has a circular peripheral contour and an arcuate edge without any sharp elements to avoid turbulence and improve flow around the valve to therefore maximize flow velocity. This translates into increased cylinder breathing in the intake cycle and reducing back pressure in the exhaust cycle.

Abstract: Vehicular airbag system includes a holder, airbag assemblies each having at least one inflatable airbag, and support brackets arranged on the holder. Each support bracket retains an airbag assembly. The support brackets have different heights relative to a plane defined by or through the holder and are positioned relative to one another such that the airbags inflate at different heights relative to the plane and an airbag inflating at a greatest height from the plane overlies at least one other airbag closer to the plane. The holder may form a housing with a cover that is broken or displaced during airbag deployment, with the support brackets and airbag assemblies being situated in a chamber defined in the housing between the holder and the cover.

Abstract: Vehicular airbag system for a driver includes a steering column, a steering wheel assembly rotatably mounted to the steering column and including a core, and a plurality of airbags arranged in the core and configured to inflate outward from the core. The airbags are nested such that each airbag is configured to inflate within or over at least one other airbag. Activatable inflator systems are configured to inflate a respective airbag at a different speed of inflation. A control system is coupled to the inflator systems and controls activation of the inflator systems and thus inflation of the airbags. The inflator systems are configured such that one of the inflator systems configured to inflate an innermost airbag has a highest speed of inflation of the inflator systems and one of the inflator systems configured to inflate an outermost airbag has a lowest speed of inflation of the inflator system.
