Abstract
A clutch includes an outer race including pawls each having first and second arms and an inner race including teeth engageable with the pawls. A cage is radially disposed between the inner and outer races and is rotatable relative to the pawls to switch the clutch between a one-way mode and a fully locked mode. The cage includes ramps each configured to urge an associated one of the first arms into engagement with the teeth when the cage is in a first rotational position to put the clutch in the fully locked mode and resilient members each configured to urge an associated one of the second arms into engagement with the teeth when the cage is in a second rotational position to put the clutch in the one-way mode.
