Pulling element for pulling a closing element out of a filter of an escape filter device, escape filter devices, escape filter device system and method for mounting an escape filter device system

An escape filter device comprising:

• a hood;
• a filter, which has a filter inlet side and a filter outlet side, integrated into the hood;
• a closing element;
• and
• a pulling element for pulling out the closing element from the filter, wherein the filter inlet side or the filter outlet side is closed in a gas-tight manner by means of the closing element and the pulling element is arranged on the closing element, the escape filter device is arranged in a device shell in a resting position with a resting distance to the device shell, and the escape filter device is moveable into a removal position with an increased removal distance to the resting distance, the pulling element comprising:
• a first fastening section for fastening the pulling element to the closing element;
• and
• a second fastening section for fastening on an inner side of the device shell, wherein the two fastening sections have a fastening distance to one another, which is smaller than or equal to the removal distance.

An escape filter device system, comprising:

• a device shell having a first inner side and a second inner side;
• an escape filter device comprising:
• a hood;
• a filter, which has a filter inlet side and a filter outlet side, integrated into the hood;
• a closing element;
• and
• a pulling element for pulling out the closing element from the filter, wherein the filter inlet side or the filter outlet side is closed in a gas-tight manner by means of the closing element and, the pulling element comprises a first fastening section for fastening the pulling element to the closing element and a second fastening section, wherein the two fastening sections have a fastening distance to one another, which is smaller than or equal to a removal distance between the device shell and the escape filter device;
• and
• a pulling element holding device, wherein:
• the escape filter device is arrangeable in a resting position in the device shell and the device shell is openable for transferring the escape filter device into a removal position;
• and
• the pulling element holding device is arranged on one of the first inner side and the second inner side of the device shell for fastening the second fastening section of the pulling element to the pulling element holding device, wherein the pulling element and the pulling element holding device are configured and are coordinated with one another such that the closing element is automatically pulled out of the filter during the opening of the device shell upon reaching the removal distance between the device shell and the escape filter device.

A method for mounting an escape filter device system the method comprising the steps of:

• providing an escape filter device comprising a hood, a filter, which has a filter inlet side and a filter outlet side, integrated into the hood, a first closing element, a second closing element, a first pulling element and a second pulling element, each pulling element comprising a first fastening section for fastening the pulling element to the closing element and a second fastening section for fastening on an inner side of a device shell, wherein the two fastening sections have a fastening distance to one another, which is smaller than or equal to a removal distance;
• providing the device shell, in which the escape filter device is arrangeable in a resting position and which is openable for transferring the escape filter device into a removal position;
• fastening the first fastening section of the first pulling element to the first closing element;
• fastening the second fastening section of the first pulling element to a first pulling element holding device at a first position on the inner side of the device shell;
• fastening the first fastening section of the second pulling element to the second closing element;
• closing the device shell until reaching a mounting position, wherein the device shell is not yet completely closed in the mounting position, and
• with the device shell in the mounting position, fastening the second fastening section of the second pulling element to a second pulling element holding device at a second position on the inner side of the device shell;
• and
• closing the device shell completely.
