Spring-loading mechanism integrated tank flap for closing/locking fuel filling connecting piece at motor car, has spring element whose end elastically extends over hinge arm such that spring load acts on flap during opening of closure unit
The flap has a spring-loading mechanism pivotally supported a hinge arm (10) and a hinge pin in a bearing block that is fastened at an edge of a hollow body. The mechanism is held in a close position by a closure unit and pressurized in an opening direction with a spring load, which is applied by a spring element (20) supported against the bearing block. An end of the spring element is molded at the hinge arm of the flap while another end elastically and partially extends over the arm such that the spring load acts on the flap during opening of the closure unit over a defined opening angle. The spring element is formed as an elongated spring arm and consists of an elastically rebounding resilient plastic material.
