## Abstract

An anti-vibration device including first and second rigid strength members interconnected by an elastomer body, the first strength member includes a base and at least three branches extending from the base along a first direction toward the second strength member, the three branches including two external branches and one central branch. The second strength member includes a transversal portion and at least two branches extending along the first direction from the transversal portion, respectively between the external branches and the central branch of the first strength member. The elastomer body extends transversally to the first direction between the external branches of the first strength member and has four legs extending respectively between the branches of the first strength member and the branches of the second strength member.

## Claims

### Claim 1

An anti-vibration device including at least first and second rigid strength members interconnected by an elastomer body,
wherein the first strength member includes a base and at least three branches extending from the base substantially along a first direction toward the second strength member, said at least three branches including two external branches and one central branch, said external branches extending from the base further than the central branch and being extended inwardly toward each other by noses,
wherein the second strength member includes a transversal portion and at least two branches extending along the first direction from the transversal portion, respectively between the external branches and the central branch of the first strength member, said second strength member including a central bar extending from the transversal portion up to outwardly extending stop members,
wherein said noses of the first strength member are respectively disposed for abutment against said transversal portion and said stop members, said stop members being disposed to avoid contact of the branches of the second strength member against the base of the first strength member in the first direction and to avoid contact of the branches of the first strength member against the transversal portion of the second strength member in the first direction,
and wherein the elastomer body extends transversally to the first direction between the external branches of the first strength member and has at least four legs extending respectively between the branches of the first strength member and the branches of the second strength member.
