Legged mobility exoskeleton device with enhanced adjustment mechanisms

Abstract:

A hip component for a legged mobility device has a hip body, and a hip insert assembly for adjusting a size of the hip component. The hip insert assembly includes a carrier assembly mounted to the hip body, and a main insert assembly spaced apart from the carrier assembly. Adjustment screws are connected to the carrier assembly and the main insert assembly. The carrier assembly includes an adjustment mechanism including a drive shaft and an adjustment chain to effect translational movement of the adjustment screws to move the main insert assembly to adjust both width and depth of the hip component simultaneously. The hip component includes abduction/adduction control mechanism that includes elastomeric bushings that are selective as to resistance level and shape to control a degree of abduction and adduction, and to preset an initial angle. A leg component includes a central carrier, and first and second housings that are located on opposite sides of the central carrier. An adjustment mechanism including a drive shaft that drives driven shafts, such as by a worm/worm gear interaction, effects movement of the first housing to relative to the second housing to adjust a length of the leg component.
