The partial decay widths into the $K_1(1270)\\bar{K}$ and $b_1(1235)\\pi$ channels are calculated via a triangular loop mechanism. In this mechanism, the $h_1$ state couples to $K^* \\bar{K}^*$, and final-state interactions between $K^*$ and $\\bar{K}^*$ proceed through pseudoscalar-meson exchange, leading to the final states $\\bar{K}$ (or $\\pi$) and $K_1(1270)$ [or $b_1(1235)$].
