Abstract
An elevator car of an elevator system includes a car body, and a car frame supportive of the car body. The car frame includes two or more opposing upright assemblies, a crosshead assembly located above the car body, and a plank assembly located below the car body. A plurality of seismic retainers are located at each of the upright assemblies. The plurality of seismic retainers are configured for a non-contact relationship with a guide rail of the elevator system during normal operation of the elevator system, and configured to react guide rail loads during a sway event via contact with the guide rail.
