Description

Detailed Description of the Invention a. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a door opening prevention device for an automobile sliding door.

b. 2. Description of the Related Art Some automobiles provided with a slide door on the side of the vehicle body have a fuel filler port provided within the sliding range of the slide door. In such an automobile, if the sliding door is accidentally opened during fueling by inserting the fuel gun into the fuel filler port, the fuel gun may be damaged or the sliding door may be deformed. There is inconvenience.

For this reason, in this type of vehicle, the door lock device of the slide door cannot be released during refueling, and more specifically, the operating member arranged inside and outside the slide door and the door lock device are connected by a transmission rod. When the door lock device is unlocked by the operation of the operation member to open the slide door, a rod restraint device is arranged beside the transmission rod. And the lid of the fuel filler port are connected by interlocking means, so that the rod restraint device is inactive when the lid is closed, and vice versa when the lid is open. It is configured.

In such a slide door, when the lid of the fuel filler port is opened for refueling, the rod restraint device operates to restrain the transmission rod and prevent the transmission rod from moving. Therefore, even if the operator tries to operate the operating member by mistake, the transmission rod does not move, so that the operating member cannot be operated and the door lock device cannot be unlocked. This can prevent accidental opening of the slide door during refueling.

g. As described above, according to the present invention, a blocking device is provided in the middle of the transmission member from the operating member to the door lock device, and the blocking device is activated when the lid of the fuel filler is opened. Since the transmission path is cut off, the door lock device cannot be unlocked even if the operating member is operated when the lid is open, which unexpectedly opens the sliding door during refueling and the sliding door refuels. It is possible to eliminate the inconvenience of colliding with the gun, and because the transmission path of the transmission member is blocked when the lid is opened, its movement is not restricted.
Even if the operating member is operated in this state, there is no fear that the operating force will act on the transmitting member as an unreasonable force, so that the deformation or damage of the transmitting member can be prevented in advance.

Further, since the idling mechanism functions according to signals from two points of the door lock knob on / off operation and the opening / closing of the lid of the fuel filler port, the unexpected opening of the slide door during refueling can be prevented.
