US Patent 9492838 Pretensioner pivot device

A flexure joint interposed between and connecting a first end and a second end has a spherical member, a receiving member configured and arranged to maintain and selectively engage the spherical member, and a connector in communication with the receiving member for releasably locking the spherical member in position as between at least a first locked position and a second locked position relative to the receiving member. Repositioning of the spherical member as between the first and second locked positions is effective for repositioning the shaft relative to the handle as between a first locked position and a second locked position.
