A modular exoskeleton structure provides force assistance to a user. The structure includes a base module including a lumbar belt capable of surrounding the waist of the user, a battery and a control unit attached to the lumber belt, a first attachment part attached to the belt and capable of cooperating with a second complementary attachment part of a hip module to attach the hip module to the base module by snapping the second attachment part into the first attachment part, and a third attachment part attached to the belt and capable of cooperating with a complementary fourth attachment part of a back module for attaching the back module to the base module.

Modular exoskeleton structure that provides force assistance to the user

The invention relates to a modular exoskeleton structure that provides force assistance to a user, comprising a base module () comprising a lumbar belt () capable of surrounding the lower trunk of the user, two hip modules capable of being attached to two respective thighs of the user, and a backpack support module () for an exoskeleton structure, comprising:

Backpack support module for a modular exoskeleton structure

A linking device for an exoskeleton structure is provided. The device an input part mounted in rotation with respect to a support, and a transmission device that when a load is applied to the input part to pivot the input part in a first direction of rotation, the transmission device transmits to a first connecting link a force to pivot the first connecting link to transfer the load to a first mechanical leg assembly and unload a second mechanical leg assembly of the exoskeleton structure, and when a load is applied to the input part to pivot the input part in a second direction of rotation opposite to the first direction, the transmission device transmits to a second connecting link a force to pivot the second connecting link to transfer the load to a second mechanical leg assembly and unload the first mechanical leg assembly.

Linking device for an exoskeleton structure facilitating the carrying of loads while walking or running

An exoskeleton subassembly is provided. The exoskeleton subassembly includes first and second exoskeleton parts, and a connecting assembly that connects the first and second exoskeleton parts. The connecting assembly includes a guide, a pin, and a limiting device. The guide is fixedly mounted on one part, and a pin fixedly mounted on the other part and slidably mounted inside the guide. The limiting device allows rotation of the pin with respect to the guide when the pin is in a first position, and to oppose the rotation when the pin is in a second position. The limiting device includes an elastic element engaged with the first part when the pin is in the second position. The elastic element exerts on the first part an elastic return force opposing relative rotation between the first and second parts both in two opposite directions of rotation.

Exoskeleton structure that provides force assistance to the user

The invention relates to an exoskeleton sub-assembly () comprising: &#x2014;a leg part () to be attached to a leg of a user, and&#x2014;a foot part () to be attached to a shoe of the user; the leg part () comprises a tibial segment () extending below the knee, along the tibia of the user, when the leg part () is attached to the leg, and the tibial segment () comprises a first component (), a second component () connected to the foot part (), and a first joint () connecting the second component () to the first component (), the first joint () permitting a rotation of the second component () with respect to the first component () caused by an internal or external rotation of the user's foot with respect to the leg.

Exoskeleton sub-assembly and exoskeleton structure including such a sub-assembly

The invention relates to a back module () for an exoskeleton structure, comprising a spinal column segment () designed to extend along a spinal column of a user, the spinal column segment () comprising a plurality of vertebral elements (), stacked on one another, and a flexible connecting element () connecting the vertebral elements () to one another, the spinal column segment () having a stable equilibrium position in which the flexible connecting element () holds the vertebral elements () supported against one another, and the flexible connecting element () being elastic so that, during a movement of the back of the user, the flexible connecting element () allows a movement of the vertebral elements () with respect to one another, while exerting a return force tending to return the spinal column segment () the stable equilibrium position.

Back module for an exoskeleton structure

The invention relates to a foot module () for an exoskeleton structure, comprising an ankle joint (), a first support plate () designed to be supported on the top of a boot of the user, when the foot module () is attached to the foot of the user, a second support plate () capable of being disposed under the sole of the boot, a first segment () connecting the ankle joint () to the first support plate () and a second segment () connecting the first support plate () to the second support plate (), the first segment () and the second segment () forming a spring capable of being compressed when the boot is in contact with the ground (S) and being expanded when the boot is not in contact with the ground (S).

Foot portion for an exoskeleton structure

The invention relates to an exoskeleton structure that provides force assistance to a user, comprising:

A shoulder module () for an exoskeleton structure that connects to an elbow module () attached to an arm of a user to a back module () attached to the back of the user. The shoulder module () has a plurality of connecting parts (), and a first pivot () connecting two of the connecting parts () while allowing rotation of one of the connecting parts with respect to the other connecting part () according to a first axis of rotation (X), during a rotation of the elbow module () with respect to the back module () corresponding to an abduction or adduction movement of the shoulder of the user. The connecting parts () include a connecting part () comprising two parts () that slide to allow shortening or lengthening of the connecting part () of the elbow module ().
