A filter element for filtering a fluid has a filter body with a filter medium folded in a zigzag shape with folds extending in a fold direction. The filter body has an end edge bonding which seals fold ends of the folds. The filter body has an outer contour with recesses. The end edge bonding, in a region of the recesses of the outer contour of the filter body, is embodied discontinuously. The end edge bonding has at least one outwardly positioned first bonding segment and an inwardly positioned second bonding segment, viewed in the fold direction. The inwardly positioned second bonding segment, in a transverse direction relative to the fold direction, is arranged at a spacing to the at least one outwardly positioned first bonding segment. The at least one outwardly positioned first bonding segment and the inwardly positioned second bonding segment bond at least one common fold.

A smart multi-modal vehicular air filtration management system including a first filter element and a second filter element disposed in a fresh air housing, wherein the fresh air housing has an inlet and an outlet. Additionally, a third filter element is provided which is disposed in a cabin housing, the cabin housing having one or more inlet. A fluid channel arranged between the fresh air and cabin housing. Finally, a diverter is included which is disposed near an outlet of the fresh air housing, wherein the diverter is configured to cause air to flow through the fresh air housing selectively through one or both of the first filter element and the second filter element.

Smart multi-modal vehicular air filtering system and associated methods

A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.

A coupling device for connecting media-conducting lines has a one-part or multi-part first coupling section and a one-part or multi-part second coupling section. At least one locking element is fastened with at least one connecting section to the first coupling section and is provided with one or more locking arc sections extending in a circumferential direction between the first and second coupling sections. The second coupling section has a locking section extending circumferentially at least partially about a circumference of the second coupling section. At least one of the one or more locking arc sections interacts with the locking section.

A filter element for an air filter has a filter bellows with a filter medium folded multiple times. A recess is disposed in the filter bellows and is designed to receive a guiding rib of the air filter. The recess is curved at least in sections thereof along a length extension of the recess. The air filter has a housing and a guiding rib, wherein the filter element is arranged at least partially in the housing and the guiding rib is immersed at least partially in the recess of the filter element. In a method for producing the filter element, the recess in the filter bellows is formed with a computer-assisted separation method that forms the recess to be curved at least in sections thereof.

A flat air filter element for an air filter has a filter medium of cellulose material and a sealing element extending circumferentially about the filter medium. Sealing element and filter medium have at least one recess at an outer contour of the flat air filter element. The sealing element has a circumferentially extending holding groove to be engaged by a housing part of a filter housing. The filter housing has a housing pot, a housing cover to cover the housing pot, and a closure element for closing the filter housing. The flat air filter element is secured in the closed state of the filter housing by circumferentially clamping the sealing element between housing pot and housing cover. The circumferentially extending holding groove of the sealing element is engaged by housing pot or housing cover. The closure element of the filter housing is arranged in the region of the recess.

A filter element is provided with a filter bellows that has an inflow side and an outflow side for a fluid to be filtered, wherein the filter bellows is made of a zigzag-folded filter medium with folds with fold edges. The inflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the inflow side and the outflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the outflow side. At least one filter element holding device is provided that holds the filter element in a filter housing. The at least one filter element holding device is connected directly or indirectly with the filter bellows. At least one supporting element supports the filter element in the filter housing; the at least one supporting element is separate from the at least one filter element holding device.
