Claim Text:
1. A switchable, hydraulic damping mount defining a first longitudinal direction comprising: a working chamber defining a first volume and configured to be filled with a hydraulic fluid; a channel; a compensation chamber defining a second volume configured to be connected to said working chamber via said channel; a partition wall configured to separate said working chamber from said compensation chamber; a first diaphragm arranged in said partition wall in such a manner so as to be deflectable in the first longitudinal direction; a switching actuator configured to control said first diaphragm and having a first state in which said first diaphragm is fixed in a rest position and a second state in which said first diaphragm is released for a movement in the first longitudinal direction; a second diaphragm arranged in said partition wall and configured to be deflectable and influence said first volume of said working chamber; an air chamber arranged between said first diaphragm and said second diaphragm and configured to be closed to the atmosphere when said switching actuator is in said first state and to be connected to the atmosphere when said switching actuator is in said second state; said switching actuator having a first member configured as an integral part of said first diaphragm and being deflectable therewith between a first position corresponding to said first state of said switching actuator and a second position corresponding to said second state of said switching actuator wherein said air chamber is connected to the atmosphere; said switching actuator having a second member coacting with said first member to move said first member with said first diaphragm between said first and second positions; a sealing seat; said first diaphragm having an annular sealing lip; said switchable mount defining at least one ventilation slot via which said air chamber can be connected to the atmosphere; said first diaphragm having at least one window via which a connection of said air chamber to said ventilation slot is enabled; said first state of said switching actuator being a deenergized state thereof; and, said first diaphragm being configured to bear against said sealing seat with said annular sealing lip so as to cause said connection from said window to said ventilation slot to be blocked for air in said air chamber.
