    Abstract: A friction based counterbalance mechanism for coupling with a closure panel of a vehicle to assist in opening and closing of the closure panel, the counterbalance mechanism including: a first housing having a first pivot connection mount for connecting to one of a body of the vehicle and the closure panel; an extension member coupled to the first housing at one end and being extendable and retractable with respect to a second housing coupled adjacent to the first housing along an axis, the second housing for connecting by a second pivot connection mount to the other of the body and the closure panel; a sliding friction mechanism having: a shaped sleeve mounted on an exterior surface of the extension member, the shaped sleeve providing an exterior friction surface; and a resilient friction element mounted to the second housing in a fixed location on the axis, the resilient friction element positioned between second housing and the shaped sleeve and biased into contact with the exterior friction surface; wherein relative movement between the shaped sleeve and the resilient friction element as the extension member is displaced generates sliding friction between the resilient friction element and the shaped sleeve.

    Abstract: The damped and compact hinge device includes a spring (17) fixed to a first member (3) and a second end coupled to interconnection means (13) having a first mobile pin (27) of a lever (23) sliding along a first slot (29) of the first member (3). The interconnection means (13) further includes a rod (31) connecting the lever (23) to a first end of a rocker arm (35), the rocker arm (35) having a first end linked via the rod (31) to the first mobile pin (27) and having an opposite end rotatably connected to a second member (5) by a fixing pin (37) spaced from a pivot pin (7). A median portion of the rocker arm (35) has a second mobile pin (41) for sliding in a second slot (43) of the first member (3), the second slot (43) being rectilinear, curved, or S or C shaped.
