  • Patent number: 7574828
    Abstract: A powered sliding device comprises wire cables (21?, 21?) provided between a sliding door (11) and a vehicle body (10), and a power unit (20) for sliding the sliding door when the wire cables are moved by the power of a motor. The power unit is provided in the inner space of the sliding door. The wire cables are composed of the door-opening cable (21?) and the door-closing cable (21?) connected to the power unit at a base end side, respectively. A front end of the door-opening cable is fixed to the vicinity of the rear end of a lower rail (14) after having passed through a lower roller bracket (18) of the sliding door, and the front end of the door-closing cable is fixed to the vicinity of the front end of a center rail (16) after having passed though a center roller bracket (19) of the sliding door.

  • Patent number: 7438331
    Abstract: An apparatus for opening and closing a door of a vehicle, which allows a door of a vehicle to be slidably moved, includes a door operation lever that is rotated when an inside knob is operated; a door holding unit that is released by rotation of the door operation lever; an operation output unit that is included in the inside knob; and a base plate on which the inside knob is arranged in such a manner that the inside knob is moved to be operated, and on which the door operation lever is arranged in such a manner that the door operation lever partially faces an area in which the operation output unit is moved in response to an operation of the inside knob. The door operation lever is rotated by making the operation output unit abut on the door operation lever when the inside knob is operated.

  • Patent number: 7334498
    Abstract: An initial tension device has a wire cable for connecting a drive unit and a movable member, a tension case fixed to an immovable member, a regular retainer engageable with an outer cable of the wire cable, and a slot formed in the tension case to extend in the longitudinal direction of the wire cable. The regular retainer engaged with the outer cable moves together with the outer cable by the tension applied to the wire cable through the length defined by the slot. The regular retainer is engaged with the outer cable in the state where a maximum tension is applied to the wire cable.

  • Patent number: 6935071
    Abstract: In the present powered sliding device for a vehicle slide door, when a center bracket is relatively rotated with respect to a slide door due to an overview shape of a center rail during a sliding movement of the slide door, the center pulley is relatively displaced in a certain amount by the rotation of the center bracket with respect to the slide door, but the center pulley is not displaced any further than the certain amount by the rotation of the center bracket.
