Abstract
A seal member for a hot gas path component in a gas turbine system is provided. The seal member includes a first seal pin, a second seal pin spaced from the first seal pin, and at least one cross-member. The at least one cross-member has a first end and a second end, and may be joined at the first end to the first seal pin and at the second end to the second seal pin. The at least one cross-member is configured to force the first and second seal pins apart when the seal member is subjected to a centrifugal force.

A bucket assembly comprising:
- a platform;
- a shank extending radially inward from the platform, the shank including a pressure side sidewall, a suction side sidewall, an upstream sidewall, and a downstream sidewall;
- a first seal pin disposed adjacent the upstream sidewall;
- a second seal pin disposed adjacent the downstream sidewall;
- and
- at least one cross-member having a first end and a second end, the at least one cross-member joined at the first end to the first seal pin and at the second end to the second seal pin,
- wherein the at least one cross-member is configured to force the first and second seal pins apart when the bucket assembly is subjected to a centrifugal force, such that the first seal pin and the second seal pin provide a seal between the bucket assembly and an adjacent bucket assembly.
