A cushion module is provided herein and includes a mounting manifold and a retaining plate. An array of pneumatic assemblies is coupled to and disposed between the mounting manifold and the retaining plate. Each pneumatic assembly includes a pneumatic cylinder having a piston rod and configured to receive pressurized air for moving the piston rod to a selected position. The pressurized air supplied to each pneumatic cylinder is variable and the piston rods collectively define a support surface having variable contour and firmness, and on which an object is rested to assess the comfortability of the support surface.

An air bleed system for a suspension fork or shock absorber includes: a fluid passage between an interior of the suspension and an exterior of the suspension; and a manually operable valve having a first position substantially closing the fluid passage and a second position allowing fluid flow between the interior and the exterior.

An air spring may include a first end member and a second end member spaced from each other; a flexible bellows having a first end portion airtightly coupled to the first end member, a second end portion airtightly coupled to the second end member, and a jacket mounted on the circumference of the flexible bellows and configured to support the flexible bellows.

A gas cylinder actuator with overtravel safety device, comprising a tubular jacket for gas containment, which is closed hermetically at one end by a bottom provided with a gas filling valve and at the opposite end by a head portion, which is provided with a hole for the passage of a stem with a piston, the jacket, the bottom and the piston forming the gas expansion and compression chamber. The head portion comprises an annular body, which is fixed internally to the jacket, and is provided with a central hole for the passage of the stem with the interposition of dynamic sealing elements, static sealing elements being interposed between the annular body and the jacket and an element for controlling the descending motion of a slider of a press with which the actuator is associated being provided and protruding from the annular body or from the jacket, the control element being preset to selectively move or break or deform in order to break or deform or render ineffective in general the static and dynamic sealing elements.

A bushing bypass. The bushing bypass includes a bushing having a top surface and a bottom surface. The bushing also includes an inner diameter surface extending between the top surface and the bottom surface. The bushing also includes an outer diameter surface extending between the top surface and the bottom surface. The bushing further includes a channel formed in the outer diameter surface. The channel extends from the top surface of the bushing to the bottom surface of the bushing.

A shock absorbing system for a bicycle front fork includes an outer tube and an inner tube which includes a piston located therein, and the lower end of the inner tube is movably inserted into the outer tube. A piston tube is connected between the lower end of the outer tube and the piston. The inner tube includes a first chamber and a second chamber formed therein with the piston located between the first and second chambers. A path formed between the piston and the piston tube. A manual valve is located in the piston tube and includes a rod and a movable part. The rod includes an extension section protruding beyond the outer tube. When the extension section is pushed, the rod moves upward to switch the path from a sealed status to an opened status, and the first chamber communicates with the second chamber.
