Abstract
A closure release device includes a housing fixedly attached to a closure and an actuating lever rotatably disposed on an axis of rotation on the housing. A crank lever is rotatably disposed on the axis of rotation. A coupling member is to selectively couple the actuating lever to the crank lever for rotation together. A shape memory alloy (SMA) actuator is to selectively cause the coupling member to selectively couple the actuating lever to the crank lever. The SMA actuator is electrically actuated. The crank lever is to connect to a latch to selectively release or engage the latch in response to a coupling state of the actuating lever with the crank lever and an actuation state of the actuating lever.
