Title: FILTER ELEMENT, IN PARTICULAR AIR FILTER ELEMENT
Abstract:
The invention relates to a filter element, in particular an air filter element (1), for a fresh air system of an internal combustion engine, or for a ventilation- and/or air-conditioning device of a motor vehicle, said filter element comprising: a filter body (2) made of a folded filter material (6), that laterally surrounds an internal space (7) of the filter element (1), except in a lateral connection region (8); a first end plate (3) and a second end plate (4) which are sealingly attached to the filter body (2) at sides that are facing away from one another; and a front plate (5) which is arranged in the connection region (8) and which has a connecting piece (13) for supplying or conducting away air. A reliable construction is formed when the front plate (5) has first and second end plate joining regions (14, 16) facing the first and second end plates (3, 4), which end plate joining regions are fused with the front-side front plate (5)-facing ends (15, 17) of each end plate (3, 4), and when the front plate (5) has first or second end fold joining regions (18, 19) assigned to a first or second end (9, 10) of the filter body (2), into which end fold joining regions at least one first or second end fold (11, 12) is plasticised, said end fold being formed at the first or second end (9, 10) of the filter body (2)
