Air filter element with retaining geometry

摘要

Disclosed is an air filter element (200) for insertion into an air filter housing, comprising an intake surface (275), a discharge surface (285), a filter medium (210), and a filter element-retaining device (240) which extends along at least a section of the periphery of the filter medium (210), between the intake surface (275) and the discharge surface (285), and which includes a retaining arrangement (270) that radially projects from the filter medium (210).

1. An air filter element for insertion into an air filter housing (100), wherein the air filter element (200) has:
an intake surface (275), a discharge surface (285), a filter medium (210), a filter element retaining device (240), wherein the filter medium (210) extends between the intake surface and the discharge surface in an axial direction of the air filter element (200), wherein the filter element retaining device is connected to the filter medium (210), wherein the filter element retaining device (240) has a retaining arrangement (270) projecting radially from the filter medium (210) and a seal arrangement (260) with a circumferential seal line (261), wherein the filter medium (210) has at least one edge (213) between the intake surface (275) and the discharge surface (285) on which a first filter medium side surface (211) and a second filter medium side surface (212) adjoin each other, wherein the filter element retaining device (240) has a radial bulge (243) on the edge, wherein the radial bulge (243) is arranged on a respective edge (213) of the at least one edge (213) of the filter medium (210), the respective edge (213) connecting the first filter medium side surface (211) and an connected adjoining filter medium side surface (212); wherein the radial bulge (243) projects radially outwardly beyond the first filter medium side surface (211) at the respective edge (213) but does not project over the adjoining filter medium side surface (212), such that the radial bulge (243) on the respective edge of the filter medium projects radially outwardly over only one side surface of the filter medium (210); wherein the seal arrangement (260) has a seal line (261) running around the filter medium (210), the seal line (261) running along the radial bulge.
