Abstract
An example of an asymmetric cuff assembly for a powered orthotic device for use by a wearer includes: a first cuff shell having a first concave interior surface shaped to overlie a first muscle of a limb of the wearer; a second cuff shell having a second concave interior surface shaped to overlie a second muscle of the limb of the wearer and having a second cross-sectional area that is greater than a first cross-sectional area of the first cuff shell; and a pivot mechanism pivotally coupling the first cuff shell to the second cuff shell along an axis that is generally parallel to the limb of the wearer with the asymmetrical cuff assembly worn by the wearer.

An asymmetric cuff assembly for a powered orthotic device for use by a wearer, the asymmetric cuff assembly comprising:
- a first cuff shell having a first concave interior surface shaped to overlie a first muscle of a limb of the wearer;
- a second cuff shell having a second concave interior surface shaped to overlie a second muscle of the limb of the wearer and having a second cross-sectional area that is greater than a first cross-sectional area of the first cuff shell;
- and
- a pivot mechanism pivotally coupling the first cuff shell to the second cuff shell along an axis that is generally parallel to the limb of the wearer with the asymmetrical cuff assembly worn by the wearer.
An arm cuff assembly for a powered orthotic device for use by a wearer, the arm cuff assembly including a first cuff shell pivotally coupled to a second cuff shell, and a retention mechanism comprising:
- a fabric strap coupled to the first cuff shell;
- and
- a ring pivotally coupled to the second cuff shell;
- wherein at least one of:
- (1) the ring can pivot between a donning state and an in-use state, the ring extending away from the second cuff shell more in the donning state than in the in-use state, at least one of the second cuff shell and the ring configured to inhibit pivoting of the ring with the ring in the donning state, and the strap includes a first portion configured to pass through the ring and to releasably attach to a second portion of the strap;
- (2) the fabric strap has an end portion that is configured to pass through the ring, and the fabric strap has a base portion that includes a strap stiffener to cause the fabric strap to extend away from the first cuff shell;
- (3) the fabric strap includes a base portion coupled to the first cuff shell and an end portion that is configured to pass through the ring and that includes an asymmetrical set of attachment jaws configured to attach to respective sides of the base portion;
- and
- (4) the fabric strap includes an end portion that is configured to pass through the ring and that includes an outer webbing member and an inner webbing member with the inner webbing member attached to the outer webbing member at at least two connection points, wherein a length of the inner webbing member between the two connection points is shorter than a length of the outer webbing member between the two connection points.
