Abstract:
An resilient member for a side bearing assembly includes a first rigid element extending in a linear direction and having a first end and a second end. A second rigid element extends in the linear direction of the first rigid element spaced from the first rigid element to provide a space between the two. The second element also has a first end. The first end of the second element is displaced along the linear direction away from the first end of the first rigid element. Resilient or elastomeric material fills the space between the first rigid element and the second rigid element with a substantially concave profile connecting the first ends of the two elements. The resilient material includes at least one weakened region along the substantially concave portion thereof as a result of assembly, which is located where the resilient material is subjected to the relatively lower stresses and strains when used in a side bearing assembly.
