Abstract: An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. In a case of assisting the user in turning left, the motor generates, when a right leg of the user is in a stance phase, a tension larger than or equal to a first threshold in each of the second, fourth, sixth, and eighth wires at an identical timing. In a case of assisting the user in turning right, the motor generates, when a left leg of the user is in a stance phase, a tension larger than or equal to the first threshold in each of the first, third, fifth, and seventh wires at an identical timing.

Abstract: A walking assistance apparatus includes a knee fastener, a heel fastener, a first wire and a second wire connected to the knee fastener and the heel fastener, a first motor connected to the first wire, a second motor connected to the second wire, and a control circuit that controls the first motor and the second motor. The first wire is connected to a first position included in a right-half region of the heel fastener. The second wire is connected to a second position included in a left-half region of the heel fastener. The control circuit acquires gait information of the user, and, based on the gait information, the control circuit controls the first motor to reduce a length of the first wire and the second motor to reduce a length of the second wire at a predetermined timing.

Abstract: An assist system includes a fist belt worn on an upper body part of a user, a second belt worn on a knee of the user, a wire, a motor coupled with a first end of the wire and disposed on the first or second belt, a drive controller that controls drive of the motor, a gyro sensor that is disposed on the second belt and that measures an angular velocity about a direction perpendicular to the direction of the wire, and a controller. When the angular velocity is greater than or equal to a first threshold with a first tension being applied to the wire using the motor, the controller outputs first information. A second end of the wire is coupled with the second belt when the motor is disposed on the first belt but coupled with the first belt when the motor is disposed on the second belt.

Abstract: An assistance apparatus includes wires that couple an upper body belt to be worn on an upper body of a user to first and second knee belts to be worn above left and right knees of the user, and a motor. In a case of assisting the user in turning left, the motor generates a tension in second and fourth wires in a period of 65% or more and 100% or less of a first gait phase of a left leg and a period of 0% or more and 20% or less of a second gait phase of the left leg, and generates a tension in sixth and eighth wires in a period of 65% or more and 100% or less of a first gait phase of a right leg and a period of 0% or more and 20% or less of a second gait phase of the right leg.

Abstract: An assist device includes an upper-body belt attached to the upper body of a user, first and second belts attached to the knees, a first wire coupling the upper-body belt to the first belt, a second wire crossing the first wire, a third wire coupling the upper-body belt to the second belt, a fourth wire crossing the third wire, and a motor coupled to one end of each of the first to fourth wires. When assisting users with walking, tensions equal to a first threshold value or greater are applied to one of the first and second wires and one of the third and fourth wires by the motor at different times. When detecting slacking of the upper-body belt, tensions equal to the first threshold value or greater are simultaneously applied to one of the first and second wires and one of the third and fourth wires by the motor.

Abstract: An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. When the assistance apparatus assists the user in turning left, the motor generates a tension larger than or equal to a first threshold in each of the second wire, the fourth wire, the sixth wire, and the eighth wire. When the fourth wire or the second wire is broken, the motor changes the wire in which a tension is generated.
