Abstract: An assist device includes: a first harness to be fitted to at least one of a shoulder region and a breast region of a user; a second harness configured to be fitted to one of a leg region and a waist region, of the user; a belt body provided so as to extend to the first harness and to the second harness along a back side of the user; an actuator provided in one of the first harness and the second harness; and a controller performs operation control of the actuator. The actuator winds a part of the belt body and unwinds the part of the belt body. The controller performs the operation control of the actuator based on a posture change of the user.

Abstract: An assist device includes a first body-worn unit that is worn on at least shoulders or a chest of a user; a second body-worn unit that is worn on each of right and left legs or a waist of the user; a belt body provided to extend along a back side of the user, from the first body-worn unit to the second body-worn unit; an actuator provided in the first body-worn unit or the second body-worn unit and allows a part of the belt body to be reeled and unreeled; a battery configured to supply electricity to the actuator; and a controller configured to control the actuator. When a remaining charge level of the battery has decreased to a predetermined set value, the controller executes a vibrating motion process of causing the actuator to perform a vibrating motion of intermittently repeating reeling of a minute amount of the belt body.

Abstract: An assist device includes a body mounting fixture, an actuator, an operation state detector, and a controller. The controller is configured to control drive of the actuator. The controller is configured to acquire an estimated posture of the wearer, which is estimated based on operation detection information detected by the operation state detector, when the actuator generates the assist torque. The controller is configured to determine whether or not the estimated posture is an unreasonable posture in which an excessive force is applied to a lower back portion.

Abstract: An assist device includes a first harness, a second harness, a belt body, an actuator and a controller. The controller is configured to perform operation control of the actuator. The controller is configured to, upon operation of the actuator being started in a state in which the first harness and the second harness is fitted to the user, perform winding of the belt body with a first winding force, and is configured to, upon the winding of the belt body being completed, change the winding force of the actuator to a second winding force that is smaller than the first winding force.

Abstract: An assist device includes a first harness, a second harness, a belt body, a mechanical unit and an attachment-detachment portion. The first harness is configured to be fitted to at least one of a shoulder region and a breast region of a user. The second harness is configured to be fitted to a leg region or a waist region of the user. The belt body is provided so as to extend to the first harness and to the second harness along a back side of the user. The mechanical unit includes an actuator provided in one harness of the first harness and the second harness and configured to wind and unwind a part of the belt body. The attachment-detachment portion is provided in the harness and the mechanical unit and is configured to detachably attach the mechanical unit to the harness.

Abstract: A second toothed member is configured to change its position between a meshing position where first teeth mesh with second teeth and a meshing releasing position where the first teeth do not mesh with the second teeth. A first toothed member and a facing member move together with an upper jacket. The second toothed member located at the meshing position receives an impact from the first toothed member so as to collide against an impact absorbing member after rupture of a guide shaft and deform the impact absorbing member. The second toothed member located at the meshing releasing position receives an impact from the facing member so as to cause rupture of the guide shaft and deformation of the impact absorbing member to occur concurrently.
