ABSTRACT:
A quick release clutch interposed between the handle and rod of a manual seat adjuster uses a piezoelectric element to create a rapid disconnect on the selective application of an electrical signal. A resilient bearing on one side of a shoulder interface maintains frictional contact between two clutch members, while an expandable piezoelectric stack on the other side pushes the shoulders apart.
