Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A seat track assembly for providing fore and aft movement of a seat along a floor of a motor vehicle includes a lower track fixedly secured to the floor. The seat track assembly also includes an upper track slidingly engaging the lower track and defining an internal channel there between. The upper track is coupled to the seat and allows for sliding movement of the seat along the lower track. In addition, the seat track assembly includes an anchor seated within the internal channel and fixedly secured to the lower track. In addition, the seat track assembly includes a reinforcement bracket seated within the internal channel and fixedly secured to the upper track. The reinforcement bracket selectively engages the anchor in response to a predetermined load to control deformation and prevent separation between the upper and lower tracks.
