The construction is fully performed in a kinematical basis and deformed Casimir functions are also explicitly obtained. The cosmological constant $\\Lambda$ is included as a Poisson-Lie group contraction parameter, and the limit $\\Lambda\\to 0$ leads to the well-known kappa-Poincar\\'e algebra in the bicrossproduct basis.
