Embodiment Construction

[0026] image 3 Shown is a front view of the upper body OK of the user AW, on which the exoskeleton 10 for supporting or increasing the working performance of the arms 20 of the user AW is arranged.

[0027] The exoskeleton 10 basically comprises a torso attachment device 30 , a bracket 9 , a lifting rod 7 , a boom 4 and a ratchet mechanism 1 .

[0028] The torso attachment device 30 is used to releasably attach the exoskeleton 10 to the torso (ie upper body OK) of the user AW (see image 3 ). The torso attachment device 30 may in this case be configured in the form of a hard shell, an elastic chest strap or a belt. Furthermore, the torso attachment device 30 comprises a closure VS arranged in the middle of the chest of the user AW, with which closure the torso attachment device 30 configured, for example, as a chest harness can be opened and closed. The closure VS may be configured, for example, as a Velcro fastener or a buckle.

Abstract

An exoskeleton for supporting at least one arm of a user, comprising a torso attachment device for releasably connecting the exoskeleton to a torso of the user; a holder for connection to the torso attachment device; a lifting rod that is reversibly movable relative to the holder in a first direction and a second direction; a boom for releasable connection to the arm of the user; and a ratchet mechanism for connecting a first end of the lifting rod to a first end of the boom, thus making it possible to selectively set the boom to perform a repeated sectorial rotary movement in a first direction of rotation and to prevent the boom from moving in a second direction of rotation.

Description

technical field [0001] The present invention relates to an exoskeleton for supporting at least one arm of a user. Background technique [0002] Exoskeletons commercially available and available for passive and / or active support of a user's limbs (especially arms) typically include hip fasteners, first and second support struts, and first arm supports and Second arm support. The first support strut and the second support strut are fastened vertically to the left and respectively right sides of the hip fastener. At the upper end of the first support strut, the first arm support is fastened in a rotatable manner via a pivot bearing. Likewise, at the upper end of the second support strut, the second arm strut is rotatably fastened via a further pivot bearing. The arm supports can be fixed at different angular positions relative to the support posts so that the user's arms can be rested on the deployed arm supports. By means of the spring, the arm support can push the user's ...
