Embodiment Construction

[0033] by means of figure 1 3 to 3 show a first exemplary embodiment of the filter element in a simplified state of production. figure 1 A perspective view of the corrugated structure 2 is shown for this purpose. The pleat structure 2 is formed, for example, from a filter web material, wherein known mechanisms such as knife pleat structures or rotary pleat structures can be used. For example, the filter web material can be heat-treated in order to better fix the pleat contours 3 . exist figure 1 The front and rear fold contours 3 can be seen in the diagram of . Reference numeral 6 shows a front end crease. Usually side strips are now glued to the pleat profile 3 in order to impart stability to the entire pleat structure 2 . This is not necessary for the filter element proposed by the invention.

[0034] figure 2 A perspective view of a corrugated structure 2 already provided with an injected plastic frame 4 is shown. The corrugation structure 2 is fastened on the corr...

Abstract

The invention relates to a filter element (1), for example a cabin filter for a motor vehicle, comprising a pleated structure (2), a plastic frame (4) that is molded at least in part to the pleated structure (2) for supporting pleat profiles (3) of the pleated structure (2), and a plastic foam seal (7) that is foamed at least in part to the plastic frame (4). In a method for producing a corresponding filter element (1), a plastic frame (4) is generated at least in part around a pleated structure (2) in a first injection molding process, and subsequently a plastic foam seal (7) is generated at least in part on the plastic frame (4) in a second injection molding process.

Description

technical field [0001] The invention relates to a filter element, in particular to a cabin air filter for a motor vehicle. Furthermore, the invention describes a method for producing a filter element. Background technique [0002] For filtering fluids such as fuel, other operating media or interior air, for example in the automotive sector, pleated or pleated filter web materials are often used. Here, it is often necessary to support the pleat profile by means of auxiliary means in order to maintain the shape when the fluid flows through. Furthermore, it is desirable to seal the filter element at its edge relative to the filter receptacle or the corresponding filter housing, so that unfiltered fluid does not get trapped in the pleated filter medium. flowed by. [0003] In order to stabilize the zig-zag filter medium with respect to the pleats, side strips of filter web material were pasted onto the pleat profiles, which on the one hand are used for stabilization and on th...
