  • Noise insulation arrangement for shift lever
    Patent number: 5941123
    Abstract: A noise insulation arrangement reduces transmission of noise through an opening of a partition having a margin with a perimeter defining the opening. A shift lever assembly extends through the opening. This arrangement uses a noise insulator including a first noise barrier portion disposed in the opening adjacent to the perimeter of the partition and a first resilient portion extending between the first noise barrier and the shift lever assembly. A insulator cover is connected between the shift lever of the shift lever assembly and the margin of the partition. The cover includes a second noise barrier portion disposed adjacent to the perimeter and a second flexible portion. The second resilient portion is in the form of a bellows extending over the first resilient portion of the noise insulator.
