Patent ID: 7048265

Claim:
A mount assembly for use with a vehicle having a frame and a vehicle body, said mount assembly comprising: a support structure having an aperture and adapted to be mounted to the frame of the vehicle; a carrier adapted to be mounted to the vehicle body and at least partially disposed within said aperture with said support structure being displaceable relative to said carrier along a line of travel when the frame moves relative to the vehicle body; and an insulator disposed between said support structure and said carrier for coupling said carrier to said support structure; said insulator having a first portion defining a first resistance and a first maximum width for isolating said displacement of said support structure during an application of a first force along said line of travel in a first direction which at least partially compresses said first portion, and a second portion defining a second resistance and a second maximum width with said second resistance being greater than said first resistance for isolating and translating said displacement of said support structure after said application of said first force and during an application of a second force along said line of travel in said first direction wherein said second force is greater than said first force such that both of said first and second portions are at least partially compressed and said second width being larger than said first width to define a ledge on said second portion extending outwardly beyond said width of said first portion, said insulator defining an opening through said first and second portions and a base extending from said openings to said ledge with said base being substantially flat relative to said support structure and abutting said support structure for ensuring that said first and second portions are properly compressed during said applications of said forces, said first and second portions having a first height that is substantially uniform between said base and a top of said first portion, and said second portion having a second height that is substantially uniform between said base and a top of said ledge for allowing said first and second portions to be compressed uniformly during said applications of said forces, said second height of said second portion being smaller than said first height of said first and second portions; said carrier defining a cup at least partially surrounding said first portion and compressing said uniform first height of said first and second portions without compressing said ledge and said second portion when said first force is applied with said cup including a flange spaced from said ledge during said application of said first force and engaging and compressing against said uniform second height of said ledge during said application of said second force.
