20090065988 | MULTIPLE STOP GAS COMPRESSION SPRING - 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. | 03-12-2009 |
20090236781 | Lockable Piston-Cylinder Unit - A lockable piston-cylinder unit includes a cylinder having at least one axially facing counterstop; a piston dividing the cylinder into a first working chamber and a second working chamber; a piston rod extending through the first working chamber to a free end outside the cylinder; and a fastening tube having a first end in which the free end of the piston rod is fixed, a second end which receives the cylinder coaxially, and at least one axially facing supporting stop. When the piston rod is extended to maximum extension, the fastening tube is rotatable relative to the cylinder from a release position, wherein the supporting stop is offset from a respective counterstop, to a locking position, wherein the supporting stop faces the counterstop so that the fastening tube cannot move axially relative to the cylinder. | 09-24-2009 |
20120126468 | UNIVERSAL WEAKENED STRUT SUPPORT - An improved adjustable lift strut support adapted for permanent attachment to a shock tube of a vehicle's failed lift strut. It is capable of quick safe attachment to a plethora of different diameter struts. It wont damage the shock tube assembly if it is left connected to the shock tube, nor will it damage the vehicles hood or liftback when they are closed with the support connected to the shock tube. | 05-24-2012 |

20090140474 | INTEGRATED CROSSOVER VALVE - An air suspension includes a crossover valve in fluid communication with a manifold, a first set of springs in fluid communication with the manifold through a first set of valves, and a second set of springs in fluid communication with the manifold through a second set of valves. The crossover valve is movable between an open position to allow fluid communication to each of the first and the second sets of springs and a closed position that separates the first set of springs from the second set of springs. | 06-04-2009 |
20090200716 | FLUID PRESSURE APPARATUS FOR A BICYCLE - A fluid pressure apparatus for a bicycle comprises a piston, a housing with a chamber dimensioned to receive the piston therein so that the piston can move axially, and first and second fluid ports in fluid communication with the chamber. The first and second fluid ports are located so that the piston is disposed between the first and second fluid ports when the piston is disposed in a piston home position. A first positioning element moves from a first home position towards a first direction, and a first biasing element biases the first positioning element towards the first home position. A first coupling element couples the first positioning element to move with the piston in the first direction, but the first positioning element and the piston move relative to each other when the piston moves in an opposite second direction. | 08-13-2009 |
