  • Publication number: 20090309325
    Abstract: A step device for a vehicle including a movable step arranged in a doorway opened and closed by a door is disclosed. The step device includes a drive unit, an open/close mechanism, a projection/retraction mechanism, and a plate cam. The open/close mechanism opens or closes the slide door. The projection/retraction mechanism moves a movable step. The plate cam is rotated by the open/close mechanism and engaged with a bushing arranged on the projection/retraction mechanism to enable or disable power transmission between the open/close mechanism and the projection/retraction mechanism. The plate cam includes a first recess and a second recess. The first recess pushes the bushing during rotation of the plate cam when the slide door is in a range of a predetermined open/close position to enable or disable power transmission between the open/close mechanism and the projection/retraction mechanism.

  • Patent number: 6811404
    Abstract: The additional segment of a wire harness 3 which is required for opening/closing a slide door 1 and constitutes a curved segment 20 is housed in a protector 9. The protector 9 has curved walls 28, 29, guide rail 30, slider 31 and first and second harness outlets 32, 33. When the slide door 1 is opened/closed, the wire harness 3 shuttles to and fro within the second wire harness outlet 33. The looseness of the wire harness when the slide door is opened/closed may be absorbed in such a manner that it is supported by an elastic member in a state where the wire harness has been curved within the protector without using the guide rail 30 and slider 31. The protecting member may be provided with a bending limiting portion, harness securing portion and flange or slanted sliding-contact portion which serve to slide the wire harness smoothly. In this configuration, it is possible to realize improvement of easiness of assembling, saving of the space and smooth operation of a power supply apparatus.
