Abstract: In a slat, in particular for an air vent in a vehicle, with a base body and an add-on part which are mounted at each other by means of a mechanical connection, the mechanical connection contains at least one holding element at one of the two components base body and add-on part and at least one receptacle for the holding element at the other one of the two components, wherein the receptacle includes at least one insertion portion, into which the holding element can be inserted in an insertion direction, and at least one succeeding holding portion, in which the holding element can be fixed.

Abstract: A non-return valve (10) for ventilating a vehicle interior, having a frame (12), in which at least one outflow opening (14) is configured. The outflow opening (14) is surrounded by a valve seat (16) and at least one valve flap (18). The valve flap (18) can move between a closed position, in which the valve flap (18) contacts the valve seat (16) and closes the outflow opening (14), and the opened position in which the valve flap (18) releases the outflow opening (14). The valve flap (18) is made of an elastically springy material and is attached such that a return force is generated which urges the valve flap (18) toward the valve seat (16).

Abstract: An air vent to be mounted on a vehicle body, has a frame molded of a plastic material and an antenna with a metallic antenna body. The antenna body is incorporated in the frame by being embedded in the plastic material or by over-molding the frame and antenna body with plastic material.
