Abstract
A self braking spool module of or for a resistance trainer that comprise a spool that can have a cable wound onto it when rotated in in a first rotational direction. A spool housing presents a sleeve about the coiled cable. When the spool in rotated in a second rotational direction to wind cable off the spool and cause spool overrun, cable spirals outwardly off the spool and contacts the sleeve to thereby apply a braking force to the spool by virtue of friction between the sleeve, spool and cable to reduce the speed of rotation of the spool in the second rotational direction.

1-33. (canceled)
A resistance trainer comprising:
- a housing,
- a resistance mechanism mounted to said housing and comprising:
- an electric motor having a rotational output axis, and
- a spool mounted to rotate about a spool axis and relative the housing,
- a user interface presented external of the housing, able to be subjected to movement by the user relative the housing when using the trainer, and
- a cable extending between the user interface and the spool and having (+) a first end region at where cable is able to wind onto the spool in a coiled configuration, and a second end region where the cable is coupled directly or indirectly to the user interface,
- wherein the resistance mechanism further comprises a coupling between the motor and the spool that is adapted and configured to couple the motor and spool for co-rotation in the same rotational direction, while allowing the motor and spool to rotationally decouple for rotation in relatively opposite directions, and
- wherein the resistance mechanism is further configured to generate a driving force of the motor that both:
- drives rotation of the spool in a first rotational direction about the spool axis to wind cable onto the spool, and
- resists, via the spool and cable, user-driven rotation of the spool in a second rotational direction about the spool axis.
40-47. (canceled)
A resistance mechanism configured for mounting to a resistance trainer, the resistance mechanism comprising:
- an electric motor having a rotational output axis, and
- a spool mounted to rotate about a spool axis and relative the housing,
- wherein the resistance mechanism unit further comprises a coupling between the motor and the spool that is adapted and configured to couple the motor and spool for co-rotation in the same rotational direction, while allowing the motor and spool to rotationally decouple for rotation in relatively opposite directions, and
- wherein the resistance mechanism is further configured to generate a driving force of the motor that both:
- drives rotation of the spool in a first rotational direction about the spool axis, and
- resists, via the spool, user-driven rotation of the spool in a second rotational direction about the spool axis.
