Foot plate assembly for use in an exoskeleton apparatus

An exoskeleton configured to be worn by a person and comprising:

• a) at least one leg structure comprising a knee pivot axis and a lower leg portion having a front side, a rear side and opposed inner and outer transversely spaced apart lateral sides, the lower leg portion is located only on an outer lateral side of the person when the exoskeleton is worn by the person, the lower leg portion extending longitudinally from the knee pivot axis;
• b) a foot plate pivotally mounted to the lower leg portion at a connection point proximate an ankle pivot axis of the person when the exoskeleton is worn by the person, the foot plate comprising an underfoot support portion and a flange extending longitudinally along the outer lateral side from the underfoot support portion towards the knee pivot axis and being supported by and pivotally mounted with respect to the lower leg portion, the foot plate having a forward portion forward of the lower leg portion, a middle section pivotally mounted to the lower leg portion and a rearward portion rearward of the lower leg portion;
• and,
• c) a biasing member housed at least partially within the lower leg portion and extending between the lower leg portion and the foot plate, the foot plate is moveably between a first position in which the rearward portion extends longitudinally away from the knee pivot axis and the forward portion extends longitudinally towards the knee pivot axis and a second position in which the rearward portion extends longitudinally towards the knee pivot axis and the forward portion extends longitudinally away from the knee pivot axis and the foot plate is biased to the first position.
