1. A portable body massager comprising:

  • a portable housing sized to be received and supported by a backrest of a conventional chair, the housing having a longitudinal axis and an external contact surface for receiving a portion of a body of a user;

    a longitudinal guide mounted in the housing;

    a carriage oriented in the housing and cooperating with the guide for limited longitudinal translation in the housing along the guide;

    a first motor supported upon the carriage, the motor having a motor output shaft driven thereby, the motor output shaft being operably coupled to the housing to translate the carriage along the guide;

    at least a pair of massage members transversely spaced about the longitudinal axis, each of the at least a pair of massage members being supported by the carriage for imparting a massage effect upon the portion of the user'"'"'s body as the carriage is translated relative to the housing;

    a second motor supported upon the carriage in operable communication with the at least a pair of massage members for driving the at least a pair of massage members relative to the carriage for providing a kneading massage effect to the user'"'"'s body corresponding to a longitudinal orientation of the carriage and for user-selected operation of the at least a pair of massage members relative to the carriage providing selective orientation adjustment of the at least a pair of massage members relative to the longitudinal axis independently of translation of the carriage along the guide so that a user can select a stationary orientation of the at least a pair of massager members for imparting the massage effect;

    a worm mounted to and driven by the motor output shaft;

    a worm gear rotatably mounted to the carriage and operably driven by the worm;

    a pinion gear rotatably mounted to the carriage and operably driven by the worm gear;

    a longitudinal rack affixed to the housing and engaged with the pinion gear such that rotation of the pinion gear translates the carriage along the guide;

    wherein the orientation adjustment of the at least a pair of massage members is controlled from a control pad; and

    wherein operation of the first motor further comprises user-selected rotation for translating the carriage to a desired longitudinal orientation.
