Exoskeleton structure that provides force assistance to the user

Abstract

The invention concerns an exoskeleton subassembly comprising: —a first exoskeleton part (32), —a second exoskeleton part (33), —a connecting assembly (60) connecting the first exoskeleton part (32) to the second exoskeleton part (33), the connecting assembly (60) comprising a guide (61) mounted securely relative to one of the first part (32) and the second part (33), and a pin (62) mounted securely relative to the other of the first part (32) and the second part (33), the pin (62) being mounted slidingly inside the guide (61) between a first end position and a second end position, wherein the connecting assembly (60) further comprises a limiting device (64) arranged to allow the pin (62) to rotate relative to the guide (61) when the pin (62) is in the first end position, and to limit the rotation of the pin (62) relative to the guide (61) when the pin (62) is in the second end position, the limiting device (64) comprising a resilient element (65) with which the first exoskeleton part (32) engages when the pin (62) is in the second end position, the resilient element (65) applying an elastic return force on the first exoskeleton part (33) that tends to resist the rotation of the first exoskeleton part (33) and the second exoskeleton part (32) relative to each other.
