  • Publication number: 20180163438
    Abstract: A self-centering handle assembly is provided for a vehicle door. The handle assembly includes a pivoting handle base coupled to the vehicle door at a pivot axis, and includes a front face having a first and second opposing ends. The first and seconds ends are configured for a selective pivotal movement in opposite directions about the pivot axis. First and second drive arms are provided extending a distance from a rear portion of the handle base and configured for coordinated movement with the respective first and second ends of the handle base. A bell crank is provided, coupled to the handle assembly, and configured to rotate about a second pivot axis. Rotation of the bell crank is driven by movement of the first and second drive arms. A biasing member is in contact with the bell crank and urges the bell crank to a return to a self-centering, rest position.

  • Patent number: 8975850
    Abstract: There is provided a driving control device of an opening and closing body, which drives the opening and closing body in a closed state by a motor through an idling section thereof. The device includes a calculation section for calculating a rotation speed difference between a rotation speed of the motor in the idling section and a current rotation speed of the motor; and an insertion detection section for detecting insertion of a foreign member based on the calculated rotation speed difference and a predetermined threshold value. The threshold value monotonously decreases according to an increase in the rotation amount of the motor to coincide with a fully-closed state threshold value at a predetermined rotation amount of the motor within an error range of the rotation amount corresponding to the fully-closed state, and to maintain the fully-closed state threshold value to a maximum rotation amount in the error range.
