The airflow device has an airflow channel which is arranged downstream of the air intake part and connected thereto and through which the air entering through the air intake part can be conducted. The airflow device has at least one air-regulating lamella which is pivotably mounted on the airflow device on a pivot bearing and which is configured and arranged such that it can influence the airflow entering through the air intake part by changing its pivot position. The pivot bearing for the at least one air-regulating lamella is formed by a first bearing portion which is part of the air intake part and by a second bearing portion which is part of the airflow channel. ## Claims ### Claim 1 An airflow device (1) for regulating the air intake (4) in vehicle front ends, the airflow device (1) comprising: an air intake part (2) through which air can enter into the airflow device (1); an airflow channel (3) arranged downstream of the air intake part (2) and connected thereto, through which the air entering through the air intake part (2) can be conducted; and at least one air-regulating lamella (5) which is pivotably mounted on the airflow device (1) on a pivot bearing (3c, 2a) and is configured and arranged such that the at least one air-regulating lamella (5) can influence the air flow entering through the air intake part (2) by changing its pivot position, wherein the air intake part (2) and the airflow channel (3) are separate components from each other, wherein the pivot bearing (3c, 2a) for the at least one air-regulating lamella (5) is formed by a first bearing portion (2a) which is part of the air intake part (2) and by a second bearing portion (3c) which is part of the airflow channel (3), wherein the air intake part (2) comprises a drive (6) coupled to the at least one air-regulating lamella (5), which drive (6) pivots the at least one air-regulating lamella (5) in the event of an actuation of the drive (6), wherein the air intake part (2) has a first drive retention portion (2b), and the airflow channel (3) has a second drive retention portion (3b), wherein the drive (6) is accommodated between the first drive retention portion (2b) and the second drive retention portion (3b). ### Claim 2 (depends on 1) The airflow device (1) in accordance with claim 1, further comprising a fastening element that is arranged in the region of an end face of the air intake part (2) facing toward the airflow channel, and/or in the region of an end face of the airflow channel (3) facing toward the air intake part (2). ### Claim 3 (depends on 1) The airflow device (1) in accordance with claim 1, further comprising a circumferential sealing element that is arranged in the region of an end face of the air intake part (2) facing toward the airflow channel, and/or in the region of an end face of the airflow channel (3) facing toward the air intake part (2). ### Claim 4 (depends on 1) The airflow device (1) in accordance with claim 1, wherein the first bearing portion (2a) is integrally formed with the air intake part (2). ### Claim 5 (depends on 1) The airflow device (1) in accordance with claim 1, wherein the second bearing portion (3c) is integrally formed with the airflow channel (2). ### Claim 6 (depends on 1) The airflow device (1) in accordance with claim 1, wherein the drive (6) is fixed to the air intake part (2) and/or to the airflow channel (3). ### Claim 7 (depends on 2) The airflow device (1) in accordance with claim 2, further comprising a circumferential sealing element that is arranged in the region of the end face of the air intake part (2) facing toward the airflow channel, and/or in the region of the end face of the airflow channel (3) facing toward the air intake part (2). ### Claim 8 (depends on 4) The airflow device (1) in accordance with claim 4, wherein the second bearing portion (3c) is integrally formed with the airflow channel (2).
