A holding plate for a vacuum cleaner filter bag, comprising
- a base plate with a through opening,
- a closing element pivotably arranged on the base plate for closing the through opening, and
- a spring element comprising a bending angle (β) that upon pivoting of the closing element in an opening direction from a first position, in which the through opening is closed, into a second position, in which the through opening is opened, in a predetermined pivoting angle range is smaller than a corresponding opening angle (α) of the closing element,
- wherein the closing element can be brought by a restoring force of the spring element in a direction opposite the opening direction from the second position into the first position, and
- wherein the spring element is arranged behind the closing element in the opening direction.
A holding plate for a vacuum cleaner filter bag, the holding plate comprising:
- a base plate with a through opening,
- a closing element pivotably arranged on the base plate for closing the through opening, and
- a spring element;
- wherein the closing element or the base plate comprises a support area on which the spring element movably rests in a contact area of the spring element, the support element comprising an elevation;
- wherein the closing element can be brought by a restoring force of the spring element in a direction opposite an opening direction from a second position in which the through opening is opened, into a first position in which the through opening is closed, and
- wherein the spring element is arranged behind the closing element in the opening direction.
