Abstract
A gas compression spring is mounted with an exterior element configured to allow a user to adjust the extension of the spring by rotating or sliding the exterior element. The user can line up an internal mechanism which is configured to limit the extension of the gas spring, and therefore stop the extension of the gas spring at a predetermined height. Additionally, an override mechanism is included where a user requires full extension of the gas spring. For example, the user can override the internal mechanism by applying a force in the direction of the extension, which disengages the mechanism allowing full extension. When the spring is compressed again, the mechanism resets and opens to the predetermined height. The gas spring can be utilized in a vehicle liftgate system, allowing the liftgate to open at one or more heights based upon the internal mechanism settings of the gas spring.
