Abstract: [Problem] To provide a passenger restraint apparatus capable of suppressing the movement of an airbag away from a passenger without requiring a complex structure. [Resolution Means] A passenger restraint apparatus according to the present invention is configured to include a seat of a vehicle and restrain a passenger seated in this seat, wherein this passenger restraint apparatus includes: an airbag which is stored in a seat back part of the seat, and expanded and deployed to the side of the passenger seated in this seat; and a tension fabric which passes through the side opposite the passenger of the stored airbag so as to be stored from the seat back part of the seat to the seat cushion part, wherein, when the airbag is expanded and deployed, at least a portion of the tension fabric is configured so as to be deployed to the outside of this seat by the cleaving of the skin of the seat, in addition to being stretched from the position in the vicinity of the shoulder of the passenger in the seat back to the position on the front side of the vehicle on the side of the seat cushion, and wherein this tension fabric includes a part for holding the surface of the airbag opposite the passenger.

Abstract: A method for identifying geometric errors with respect to at least two translational axes and at least one rotational axis of a machine using a control device is disclosed. The method comprises the steps of: measuring positions of a jig in three-dimensional space using a position measurement sensor, wherein a measurement is carried out when the jig being indexed around the rotational axis by a plurality of angles is located at the positions; approximating a plurality of measured values of the positions measured in the measuring step to a circular arc; and calculating an error in regard to a center position of the rotational axis and/or a tilt error in the rotational axis, and tilt errors in the translational axes, based on the circular arc resulting from the approximating step.

Abstract: First of all, in a first step S1, each actuator command value for position command value and posture command value of an end-effector is determined. Next, in a second step S2, rotational resistance values of a first and a second universal joints are obtained, and in a third step S3, the force and the moment exerted to each of the second universal joints are computed using this, and in a fourth step S4, the resultant force and the resultant moment exerted to the end-effector are determined from these. Then, in the fifth step, the elastic deformation amount of a mechanism is computed using these, and a compensation amount of the actuator command value is computed using these values. And then, in the sixth step, the actuator command values determined in the first step are updated with the compensation amount determined in the fifth step taken into account.
