  • Patent number: 5533597
    Abstract: The present invention provides a suspension control device with which the damping coefficient of the suspension can be easily adjusted on the basis of only the vertical vibration of a body of a vehicle, without measurement of the relative velocity or the relative displacement between the body and the wheel along the vertical direction. The absolute velocity of the body 1 is calculated on the basis of the detected signal of the acceleration sensor attached to the body 1, then the rotation angle .theta. of the movable plate is calculated on the basis of the absolute velocity, and the movable plate is rotated in the predetermined direction by the rotation angle .theta.. Accordingly, the damping coefficient is adjusted so that the coefficient in the extension of the shock absorber becomes larger and the coefficient in the compression of the shock absorber becomes smaller, or so that the damping coefficient in the extension becomes smaller and the coefficient in the compression becomes larger.

  • Patent number: 4749144
    Abstract: An emergency locking retractor for seat belts comprises a spindle, a swing member loosely inserted into the spindle and having engaging teeth on the outer periphery thereof, a locking member having internal teeth engageable with the engaging teeth of the swing member, a synchrogear slidably rotatable with the spindle to engage the swing member with the locking member, and an acceleration sensing device engagable with the synchrogear. The swing member has a supporting tooth in addition to the engaging teeth, the synchrogear is provided with a balance weight for compensating deviation of the center of weight of the swing member from the rotation center of the spindle, and the spindle is provided with a reinforcing plate and further with projections integrally formed which are so positioned that the projected portions may be present on the upper surface of the swing member to prevent any upward movement of the swing member causing disengagement.
