Claim 5:
6. A position-relative damper assist system (1) according to claim 5, wherein the chamber (13) containing the piston head (11) of the piston assembly (9) is defined about a portion of the top mounting component (5), and wherein the biasing component (35) with corresponding jounce displacement-profile surface (35a) is mounted onto the top mounting component (5) and is disposed along the chamber (13) of said top mounting component (5);
wherein the biasing component (35) includes a profiled bar (37) being provided with the jounce displacement-profile surface (35a);
wherein the profiled bar (37) is removably and pivotably mountable onto the top mounting component (5) via an attachment component (59);
wherein the profiled bar (37) is disposed centrally within the chamber (13) of the top mounting component (5);
wherein the piston head (11) comprises a corresponding central hole (39) for receiving therethrough the profiled bar (37) of the biasing assembly (21) during a relative displacement of the bottom mounting component (3) with respect to the top mounting component (5);
wherein the piston head (11) further comprises an interlocking component (41) disposed about the corresponding central hole (39) for interlocking with the profiled bar (37) during displacement of the profiled bar (37) through said corresponding central hole (39);
wherein the interlocking component (41) includes a pin (41a) being removably mountable onto the piston head (11) via a fastener (43), the pin (41a) being positioned, shaped and sized for extending within the corresponding central hole (39) and for further fitting into a corresponding slot (41b) disposed about the profiled bar (37);
wherein the pin (41a) is removably insertable into a corresponding receiving passage (85) defined about the piston head (11);
wherein the receiving passage (85) is disposed transversally with respect to the piston head (11);
wherein the receiving passage extends from the central hole (39) of the piston head (11) to a side surface (11c) of the piston head (11);
wherein the fastener (43) is positioned, shaped and sized so that a top portion thereof is lodged within a corresponding recess (45) of the piston head (11) of the piston assembly (9), so as to prevent the top portion of the fastener (43) from exceeding beyond a top surface (11a) of said piston head (11);
wherein the position-relative damper assist system (1) comprises a hollow separator component (47) being removably mountable onto the piston head (11), for use with an internal accumulator (49a), the hollow separator component (47) having an opened end operatively connectable to the corresponding central hole (39) of the piston head (11), and an opposite closed end for separating a fluid (51) of the internal accumulator (49a) from the fluid (17) of the chamber (13);
wherein the hollow separator component (47) is long enough for receiving the profiled bar (37) when the top and bottom mounting components (5,3) are operated in the compression mode;
wherein the profiled bar (37) is long enough for interacting with the jounce adjustment component (19a) when the top and bottom mounting components (5,3) are operated in the extension mode;
wherein the jounce adjustment component (19a) includes a spring-loaded plunger (53) having one end interacting with the jounce displacement-profile surface (35a) for moving in response to a corresponding contour of said jounce displacement-profile surface (35a);
wherein the jounce adjustment component (19a) includes a spring-loaded poppet (55) provided with an adjacent ball-bearing (57) interacting with the jounce displacement-profile surface (35a) for moving in response to a corresponding contour of said jounce displacement-profile surface (35a);
wherein the poppet (55) comprises a shouldering portion (31a) for resting against a corresponding abutment portion (33a); and
wherein a cross-sectional profile of the ball-bearing (57) is smaller than a cross-sectional profile of the poppet (55).
