Claims28
An exoskeleton for a limb of a user wherein the limb has an upper portion connected to the body of a user and a lower limb portion, the exoskeleton comprising:
- a) a body portion;
- b) at least one limb structure comprising an upper limb portion moveably mounted to the body portion and a lower limb portion moveably mounted to the upper limb portion;
- c) a first drive motor provided on the upper limb portion and having a motor axis that extends generally parallel to the upper limb portion;
- and,
- d) a first drive force transmission mechanism drivingly connecting the drive motor to one of the body portion and the lower limb portion, the first drive force transmission mechanism comprising a first gear provided on an upper end of the lower limb portion or on the body portion and a first transfer member extending transverse to the motor axis.
An exoskeleton comprising:
- a) a left leg structure, a right leg structure and a waist member, each leg structure comprising an upper leg portion and a lower leg portion moveably mounted relative to the upper leg portion;
- b) a drive motor provided on the upper leg portion;
- and,
- c) a drive force transmission mechanism drivingly connecting the drive motor to the lower leg portion
- d) a plurality of straps securing a user to the leg structures whereby the user's weight is transmitted to the exoskeleton by the left and right leg structures.
