Leading and subleading twist transverse momentum dependent partondistribution functions (TMDs) are studied in a quark model framework providedby the bag model. A complete set of relations among different TMDs is derived,and the question is discussed how model-(in)dependent such relations are. Aconnection of the pretzelosity distribution and quark orbital angular momentumis derived. Numerical results are presented, and applications for phenomenologydiscussed. In particular, it is shown that in the valence-x region the bagmodel supports a Gaussian Ansatz for the transverse momentum dependence ofTMDs.
