  • Housing of a heating or air-conditioning system of a motor vehicle and method thereof
    Patent number: 6296284
    Abstract: A housing and a housing assembly method of a heating or air-conditioning system of a motor vehicle has at least two housing parts that can be sealingly connected to one another along their separating plane. The peripheries of each housing part has a tongue and groove connecting members. The two housing parts are held together with the tongue and groove connecting members by displacing the two housing parts linearly relative to one another along the separating plane so that the tongue and groove formed around the peripheries of the two housing parts sealingly connect together. Locks or latches are provided in the tongue and groove connection to prevent the housing parts from inadvertently displacing along the separating plane.
