ABSTRACT:
TECHNICAL FIELD
The invention relates to a body flap for the tank filler neck with a remote unlocking mechanism for passenger vehicles using a locking bolt engaged with a closure part by way of a spring and disengaged from the closure part by way of a solenoid.
DISCUSSION OF THE PRIOR ART
DE 25 33 104 A1 discloses a tank closure for passenger vehicles with a remote unlocking mechanism in which a spring-loaded locking bolt can be disengaged, via a solenoid, from a closure part on a body flap. In the case of the known tank closure for passenger vehicles, the solenoid can be arranged directly on a base plate which can be arranged in the direct vicinity of the body hollow which accommodates the tank filler neck. In this known body flap for the tank filler neck with a remote unlocking mechanism, the region directly adjacent to the body hollow, which accommodates the tank filler neck, has to be accessible from the body interior, and an appropriate fixing means for the base plate, on which the solenoid is arranged, has to be provided. In the case of a passenger vehicle of the sports coupe type, as a consequence of the short, rear body overhang and the tank filler neck arrangement which is required because of the tank position, the difficulty can arise of the region directly adjacent to the body hollow of the tank filler neck not being readily accessible for the installation of a base plate with a solenoid and the locking bolts.
SUMMARY OF THE INVENTION
An object of the invention is to provide an assembly for a body flap for the tank filler neck with a remote unlocking mechanism, which assembly enables the locking bolt, which interacts with the body flap, to be used even in difficult space conditions and enables the base plate to be mounted in a readily accessible position. According to the invention this object is achieved by a body flap for a tank filler neck, of the type explained in the preamble of patent claim

, having the features listed in the defining part of patent claim

.
As the result of the solenoid and the locking bolt being arranged in the side limbs of a U-shaped plastic component, and the armature of the solenoid acting on the locking bolt via a lever linkage which is mounted in the base of the U-shaped plastic component, a U-shaped assembly is provided in which the locking bolt can extend, supported via a seal, into the body hollow of the tank filler neck and this assembly can be fixed in a position which is favorable for installation with its base plate, which is formed by one side limb, on an inside panel of the body. A Bowden cable laid in a U-shaped bend can be used instead of the lever linkage.
A lever arrangement may be used to make manual unlocking possible if there is a fault in the electrical system.
