Exoskeleton e.g. knee exoskeleton, arrangement for patient, has Bowden cable system coupled to circular arc joint, where circular arc joint causes displacement of joint components relative to each other when subjected to traction force

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes an exoskeleton arrangement, such as a knee exoskeleton, that uses a special circular arc joint attached to a limb joint. The movement is achieved by pulling on a Bowden cable, which causes the joint components to move relative to each other in a controlled manner, simulating a natural limb motion.

Use CasesContent extracted from patent full text and abstract with AI.

• Rehabilitation devices for patients recovering from injuries affecting the knee or other limb joints
• Assistive equipment for people with mobility impairments to support walking or standing
• Wearable robotic exoskeletons for augmenting human strength or performance in industrial or military applications
• Physical therapy tools to help improve patient mobility and strength
• Support devices for elderly individuals to aid in daily activities

BenefitsContent extracted from patent full text and abstract with AI.

• Provides controlled and natural movement of limb joints, closely mimicking physiological motion
• Offers adjustable assistance or resistance for personalized rehabilitation or support
• Reduces mechanical complexity by efficiently transferring force via the Bowden cable system
• Can be adapted to multiple limb joints, not limited to the knee
• Enhances comfort and fit due to sliding surfaces and articulated joint design

Patent Abstract

The arrangement has a circular arc joint (1) attached to a limb joint, and a set of joint components (5, 7) articulately connected to the circular arc joint. The joint components are displaceable relative to each other by displacement along a circular arc. A Bowden cable system is coupled to the circular arc joint, where the circular arc joint is coupled to an exoskeleton drive and causes the displacement of the joint components relative to each other when the joint is subjected to a traction force. A sliding surface is formed at one of the joint components.
