A latch assembly for a compartment of a vehicle interior is provided. The latch assembly comprises a frame, a first pawl member, a second pawl member, a lever member, and a resilient member. The frame has a first portion, a second portion, and a third portion. The frame is fixed to a cover of the compartment. The first pawl member is slidingly disposed in the first portion of the frame. The second pawl member is slidingly disposed in the second portion of the frame. The lever member has a first and a second pivot pin and a center hub. The center hub is rotatably supported by the third portion of the frame. The first pivot pin is disposed in the first pivot slot of the first pawl member. The second pivot pin is disposed in the second pivot slot of the second pawl member.

A mount assembly is provided for mounting a component, such as an engine, to a vehicle for active control of vibration. The assembly includes first and second mounting members and, an intermediate insert with first and second elastomeric systems connecting said first and second mounting members with the intermediate insert in between. An actuator in parallel with said first elastomeric system provides vertical force to said first elastomeric system to provide a relatively soft vertical rate. A controller operates the actuator in response to sensed vibration so that the vertical force tends to avoid or cancel it. A relatively high fore/aft and lateral dynamic rate of the first system protects the actuator. The second elastomeric system connects the second mounting member with the intermediate insert and exhibits a relatively high vertical rate and a relatively soft fore/aft and lateral rate. One or more sensors feeds data to a controller that analyzes the vibrations to determine the harmonics thereof. The controller then constructs one or more output waveforms and feeds them to the actuator so that a force is applied across the first elastomeric system between the first mounting member and the intermediate insert, thereby tending to produce the relatively soft vertical rate for component isolation and noise suppression.
