The Belle Collaboration has recently reported a study of the decays B → Ds1(2536)+ and has given also estimates of relevant ratios between branching fractions of decays B → D(*)DsJ(*) providing important information to check the structure of the Ds0*(2317), Ds1(2460) and Ds1(2536) mesons. The disagreement between experimental data and Heavy Quark Symmetry has been used as an indication that Ds0*(2317) and Ds1(2460) mesons could have a more complex structure than the canonical one. We analyze these ratios within the framework of a constituent quark model, which allows us to incorporate the effects given by finite c-quark mass corrections. Our findings are that while the Ds1(2460) meson could have a sizable non- component, the Ds0*(2317) and Ds1(2536) mesons seem to be well described by a pure structure.
