Device for supporting at least one arm

A device for supporting the arms of a user, the device comprising:

• a first arm support element with a first arm shell for placing on a first arm;
• a second arm support element with a second arm shell for placing on a second arm;
• at least one passive actuator configured to apply a force to at least one of the first and second arm support elements;
• at least one counter bearing which comprises at least one force transmission element and a counter bearing element, wherein the first and second arm support elements are each connected to the at least one force transmission element via a first joint such that the first and second arm support elements can be swivelled about at least one swivel axis, wherein the at least one force transmission element is connected to the counter bearing element via a second joint such that the at least one force transmission element can be swivelled;
• wherein application of the force to at least one of the first and second arm support elements by the at least one passive actuator when at least one of the first and second arms of the user is raised such that an elbow of the user is above a shoulder of the user causes displacement of at least one of the first and second arm shells along the at least one of the first and second arms of the user toward at least one of a first and second hand of the user,
• wherein the device also comprises at least one restraining element to restrict the displacement of at least one of the first and second arm shells along at least one of the first and second arms towards at least one of the first and second hands of the user when the device is mounted and the at least one passive actuator applies the force to the at least one of the first and second arm support elements, but which does not influence a displacement of the first and second arm shells in the opposite direction;
• wherein the at least one restraining element is designed to be flexible yet inelastic and forms a loop with at least one further section of the device, wherein the loop is formed on a torso of a user when the device is mounted on the user.

A device for supporting the arms of a user, the device comprising:

• a first arm support element with a first detachable arm shell for placing on a first arm;
• a second arm support element with a second detachable arm shell for placing on a second arm;
• at least one passive actuator configured to apply a force to at least one of the first and second arm support elements;
• at least one counter bearing which comprises at least one force transmission element and a counter bearing element, wherein the first and second arm support elements are each connected to the at least one force transmission element via a first joint such that the first and second arm support elements can be swivelled about at least one swivel axis, wherein the at least one force transmission element is connected to the counter bearing element via a second joint such that the at least one force transmission element can be swivelled;
• wherein application of the force to at least one of the first and second arm support elements by the at least one passive actuator when at least one of the first and second arms of the user is raised such that an elbow of the user is above a shoulder of the user causes displacement of at least one of the first and second arm shells along the at least one of the first and second arms of the user toward at least one of a first and second hand of the user,
• wherein the device also comprises at least one restraining element in the form of an item of clothing or part of an item of clothing, the item of clothing being a t-shirt, a shirt, a vest or a jacket, the restraining element being adapted to restrict the displacement of at least one of the first and second arm shells along at least one of the first and second arms towards at least one of the first and second hands of the user when the device is mounted and the at least one passive actuator applies the force to at least one of the first and second arm support elements in a direction of the first and second hands of the user, but which does not influence a displacement of the first and second arm shells in the opposite direction;
• wherein the at least one restraining element features a reinforcement and is designed to be flexible yet inelastic.
