1. An evacuation slide, comprising:
- a slide lane;
an extension;
a hinge portion coupled between the extension and a head end of the evacuation slide configured to buckle in response to bearing a weight of at least 50 lbs and in response to a door sill height being less than or equal to a predetermined height; and
a lane diverter coupled to the evacuation slide, the lane diverter configured to contact an exit surface and deform a portion of the evacuation slide in response to the buckling;
wherein the deforming is configured to redirect the slide lane to a side exit of the evacuation slide.

Abstract
An evacuation system is provided. The system may comprise a girt coupled to a door sill and an evacuation slide. The evacuation slide may comprise a head end coupled to the girt, an extension, a hinge portion coupled between the head end and the extension, and a lane diverter coupled to the evacuation slide. A method is also provided. The method may include opening a door to expose a door sill, inflating the evacuation slide with the evacuation slide coupled to the door sill, bending a hinge portion of the slide in response to a door sill height being less than or equal to a predetermined height, and redirecting a slide lane to a side exit.
