Orthopedic device

An orthopedic device comprising:

• a shell mechanism configured to have an open position, configured for a body part to be brought into the shell mechanism, and a closed position, in which the shell mechanism is configured to be engaged at least partially around the body part arranged in the shell mechanism;
• at least one actuation element which is configured to be actuated when the body part is introduced into the shell mechanism, and which brings the shell mechanism from the open position to the closed position, wherein the at least one actuation element comprises a tensile force transmission element, the tensile force transmission element having a length that is shorter than an inner circumference of the shell mechanism in the closed position;
• wherein the tensile force transmission element extends in the shell mechanism and is configured such that the body part inserted into the shell mechanism contacts and moves the tensile force transmission element thereby applying a tensile force that moves the shell mechanism from the open position to the closed position to partially encompass the body part, and wherein the tensile force transmission element is a cloth.
