Title:
HYDRAULIC DAMPER WITH COMPRESSED GAS EXTEND ASSIST
Document Type and Number:
WIPO Patent Application WO/2018/200964
Kind Code:
A9
Abstract:
A dampening system (28) that includes an actuation state and/or a door actuation system that includes a single-use pressurized tank (34). The dampening system or the door actuation system may include a damper (30) and a fluid pressure source (e.g., the single-use pressurized tank (34)) that pressurizes the damper to actuate from a first position to a second position. The pressurization allows the damper to actuate another component, such as a vehicle door (26) that is operably coupled to the damper. A user may shift the damper into the actuation state to actuate the vehicle door open during an emergency, such as when a military vehicle is on its side after an explosion knocks over the vehicle and the vehicle door is too heavy for the user to open without assistance.
