Each of the guide channels has a first end and a second end. A housing is mounted to the first ends of the guide channels. A shield is configured to: deploy from the housing; travel along the guide channels toward the second ends of the guide channels; and cover at least a portion of the opening, An actuator is configured to, in response to being triggered, deploy the shield from the housing and move the shield along the guide channels toward the second ends of the guide channels.
