Abstract: A counterbalance mechanism for coupling with a closure panel to assist in opening and closing of the closure panel between a fully closed position and a fully open position of the closure panel, the counterbalance mechanism including: a housing coupled at one end to one of the closure panel and a body of a vehicle by a first connector and at another end by a second connector to the other of the body and the closure panel, the housing containing an extension member and a spring positioned along a longitudinal axis, the spring positioned adjacent to the first connector; the first connector having a body with a connection portion coupled by a connection to an end of the housing positioned at the one end; and a spring retention mechanism for inhibiting extension of the spring out of the one end of the housing, the spring retention mechanism including: a spring retainer positioned between the spring and the end; and a retainer pin positioned between the spring retainer and the end; wherein upon decoupling of the connection portion with the end, the retainer pin inhibits movement of the spring and the spring retainer towards the one end along the longitudinal axis.

Abstract: A method for constructing an extension mechanism for a closure panel of a vehicle, the extension mechanism including an extension member housed in a body housing, such that the extension member extends and retracts with respect to the body housing as the closure panel is opened and closed, the extension mechanism having a first connection at one end for connecting the extension member to the vehicle and a second connection at the other end for connecting the body housing to the vehicle, the method comprising the steps of: overlapping a tube wall of the body housing with an end portion of the body housing, the end portion having a receiving indentation; receiving a deformed portion of the tube wall into the receiving indentation in order to form a crimp connection between the tube wall and the end portion; and positioning a clamping member having a body by at least a portion of the body over the tube wall, such that the deformed portion is sandwiched between the portion of the body and the receiving indentation.

Abstract: A motor-less counterbalance strut for selectively braking pivotal movement of a closure member includes a housing connected to one of closure member and a motor vehicle body and an extensible member slideably moveable relative to housing connected to the other of closure member and motor vehicle body. The extensible member has a rotary drive member configured to drive a driven member and cause movement of extensible member between retracted and extended positions. A gearbox unit has an input operably driven by a rotary output of the rotary drive member and an output operably driven in response to the movement of the input. The output is fixed to a friction plate configured for operable communication with a brake rotor. An electro-mechanical actuator is operable to move brake rotor into and out of braking engagement with friction plate to establish a braking and non-braking condition of extensible member.

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: A extension mechanism for coupling with a closure panel to assist in opening and closing of the closure panel for at least a portion of a path including a housing member, an extension member and one or more bushings for positioning the extension member within the housing member. The bushings can provide friction for assisting in hold positions of the extension mechanism. The extension mechanism can be incorporated as part of a biasing strut such as a spring configured strut.

Abstract: An electromechanical strut is provided for moving a pivotal closure member between open and closed positions relative to a motor vehicle body. The electromechanical strut includes a drive mechanism having a motor-gearbox assembly, flex coupling assembly, and a spring-loaded supplemental friction assembly that are operable to drive a rotatable power screw. The drive mechanism converts rotary motion of the power screw into linear motion of an extensible member to move the extensible member between a retracted position corresponding to the closure member closed position and an extended position corresponding to the closure member open position. The motor-gearbox assembly includes a motor and a geartrain having an output component driven at a reduced speed relative to the motor speed. The flex coupling assembly is operably disposed between the output component and the power screw. The spring-loaded supplemental friction assembly generates and applies a supplemental frictional force to the flex coupling assembly.
