Abstract: The invention relates to a modular exoskeleton structure that provides force assistance to a user, comprising a base module (1) comprising a lumbar belt (11) 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 (14) for an exoskeleton structure, comprising: a hoop (141) designed to be anchored to the hip modules, at the hips of a user, a support rod (142) designed to extend along the back of the user and capable of being engaged in a pouch of a backpack to suspend the backpack to the backpack support module (14), wherein the rod (142) comprises a first rod element (1421) connected to the hoop (141), a second rod element (1422) capable of sliding with respect to the first rod element (1421) so as to vary a length of the rod (142), and a damper for cushioning the movement of the second rod element (1421) with respect to the first rod element (1422) caused by the walking of the user.

Abstract: 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.

Abstract: The invention relates to a foot module (7) for an exoskeleton structure, comprising an ankle joint (72), a first support plate (732) designed to be supported on the top of a boot of the user, when the foot module (7) is attached to the foot of the user, a second support plate (735) capable of being disposed under the sole of the boot, a first segment (731) connecting the ankle joint (72) to the first support plate (732) and a second segment (733) connecting the first support plate (732) to the second support plate (735), the first segment (733) and the second segment (735) 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).

Abstract: The invention relates to an exoskeleton structure that provides force assistance to a user, comprising: a first module capable of being attached to a first portion of the body of a user, a second module capable of being attached to a second portion of the body of the user, the second module being connected to the first module by means of a joint (52, 62) allowing rotation of the second module (5, 6) with respect to the first module, an actuator (521) comprising a stator (522) and a rotor (523) capable of being driven in rotation with respect to the stator (522) to move the second module (5, 6) in rotation with respect to the first module (1, 5), and an elastic return element (524) arranged to: in a first angular range of movement (?1) of the rotor with respect to the stator (522), not exert any return force on the rotor (523) and, in a second angular range of movement (?2) of the rotor (523) with respect to the stator (522), exert a return force tending to oppose rotation of the rotor (523) with respect to

Abstract: The invention relates to a back module (2) for an exoskeleton structure, comprising a spinal column segment (21) designed to extend along a spinal column of a user, the spinal column segment (21) comprising a plurality of vertebral elements (211), stacked on one another, and a flexible connecting element (212) connecting the vertebral elements (211) to one another, the spinal column segment (21) having a stable equilibrium position in which the flexible connecting element (212) holds the vertebral elements (211) supported against one another, and the flexible connecting element (212) being elastic so that, during a movement of the back of the user, the flexible connecting element (212) allows a movement of the vertebral elements (211) with respect to one another, while exerting a return force tending to return the spinal column segment (21) the stable equilibrium position.

Abstract: The invention relates to a shoulder module (3) for an exoskeleton structure, the shoulder module (3) being designed to connect an elbow module (4) attached to an arm of a user to a back module (2) attached to the back of the user, the shoulder module (3) comprising: a plurality of connecting parts (34, 36, 38, 310), and a first pivot (35) connecting two of the connecting parts (34, 36) while allowing rotation of one of the connecting parts with respect to the other connecting part (34) according to a first axis of rotation (X1), during a rotation of the elbow module (4) with respect to the back module (2) corresponding to an abduction or adduction movement of the shoulder of the user, in which the connecting parts (34, 36, 38, 310) include a connecting part (38) comprising two parts (381, 382) mounted sliding with respect to one another by means of a slideway (383), the sliding of the parts (381, 382) with respect to one another allowing shortening or lengthening of the connecting part (38) of the elbow m
