Claims18
A vibration dampener for a structural frame member comprising:
- at least one generally disk shaped member having a centrally disposed aperture formed by an inner wall, an outer wall spaced radially from the inner wall with a web disposed therebetween, the outer wall adapted to be received by at least a portion of the structural frame member;
- and
- a cylindrical rod adapted to be inserted in the central aperture of said at least one disk shaped member, wherein said cylindrical rod cooperates with said at least one disk shaped member to dampen vibration from the structural frame member, wherein the web includes a plurality of radially outwardly extending spokes having a generally S-shaped cross section.
A vibration dampener for a vehicle frame member comprising:
- a pair of generally disk shaped members each having a centrally disposed aperture formed by an inner wall, an outer wall spaced radially from the inner wall with a web disposed therebetween, the outer walls adapted to be received by at least a portion of the vehicle frame member, wherein the web includes a plurality of radially outwardly extending spokes;
- and
- a rod adapted to be inserted in the central apertures of said pair of said disk shaped members, wherein said rod cooperates with said disk shaped members to dampen vibration from the vehicle frame member.
A vibration dampener for a vehicle steering column assembly comprising:
- a steering column support bracket adapted to receive a steering column, said steering column support bracket being adapted to be attached to at least one of a cross car beam assembly and a firewall of the vehicle;
- a pair of generally disk shaped members each having a centrally disposed aperture formed by an inner wall, an outer wall spaced radially from the inner wall with a web disposed therebetween, the outer walls adapted to be received by at least a portion of said steering column support brackets, wherein the webs include a plurality of radially outwardly extending spokes;
- and
- a rod adapted to be inserted in the central apertures of said pair of said disk shaped members, wherein said rod cooperates with said disk shaped members to dampen vibration from the vehicle in said steering column support bracket.
