Abstract: A static cycling machine includes a base assembly. A front post support structure is arranged on the base assembly. A front post assembly is arranged on the front post support structure and is angled forward with respect to a support substrate, the front post assembly being adjustable in length and configured to permit a handlebar assembly to be mounted thereon. A rear post support structure is arranged on the base assembly. A rear post assembly is arranged on the rear post support structure and is angled rearward with respect to the support substrate, the rear post assembly being adjustable in length and configured to permit a seat assembly to be mounted thereon. Linear actuators are arranged on respective support structures and operatively engaged with respective post assemblies to adjust the lengths of the post assemblies. A control system controls operation of the linear actuators. A crank assembly is arranged on at least one of the base and support structures.

Abstract: A static cycling machine includes a support assembly and a drive assembly. A frame assembly is mounted on the support assembly. The frame assembly includes a seat tube assembly extending from the drive assembly, the seat tube assembly being adjustable in length. A down tube assembly extends from the drive assembly, the down tube assembly being adjustable in length. A handlebar assembly is mounted on the down tube assembly. A fork assembly is connected to the handlebar assembly and is adjustable in length. The seat tube, down tube, handlebar and fork assemblies are connected to each other such that at least the dimensions of the frame assembly can be adjusted by adjusting the lengths of the tube assemblies. A driven wheel assembly is operatively connected to the drive assembly so that work applied to the drive assembly can be transmitted to the wheel assembly. Actuators are operatively engaged with the frame assembly to adjust dimensions of the frame assembly.

Abstract: An airbag module 20 is described having side walls 28, 29 which are weakened by being out of plane so that upon contact from a knee bolster 17 they collapse in a controlled manner.
