A backrest adjustment pin assembly provides for adjustment of the backrest assembly and the seat assembly. The backrest adjustment pin assembly may be operated either by directly retracting a lock pin or remotely by actuating a remote handle assembly. ## Claims ### Claim 1 A weight bench system comprising: a seat assembly; a backrest assembly, said backrest assembly includes a rear backrest link pivotally attached to a forward backrest link at a backrest pivot axis, said forward backrest link pivotally attached to an intermediate link at an intermediate pivot axis, said intermediate link attached between said seat assembly and said backrest assembly; and a backrest adjustment pin assembly engaged with sad rear backrest link, said backrest adjustment pin assembly includes a lock pin engaged with a lever, said lock pin axial movable along an axis transverse to an axis about which said lever pivots. ### Claim 2 (depends on 1) The system as recited in claim 1, further comprising a frame assembly, said rear backrest link pivotally attached to said frame assembly at a rear pivot axis, said intermediate link pivotally attached to said frame assembly. ### Claim 3 (depends on 1) The system as recited in claim 1, wherein said lock pin includes a longitudinal slot within which an arm of said lever is received. ### Claim 4 (depends on 3) The system as recited in claim 3, wherein said lock pin is spring biased. ### Claim 5 (depends on 3) The system as recited in claim 3, wherein said lever is spring biased. ### Claim 6 (depends on 1) The system as recited in claim 1, further comprising a remote handle assembly connected to said lever. ### Claim 7 (depends on 6) The system as recited in claim 6, further comprising a cable which connects said remote handle assembly to said lever. ### Claim 8 (depends on 6) The system as recited in claim 6, wherein said remote handle assembly is mounted to said backrest assembly. ### Claim 9 (depends on 1) The system as recited in claim 1, wherein said seat assembly includes a seat cushion frame support link pivotally mounted to said intermediate link. ### Claim 10 (depends on 9) The system as recited in claim 9, further comprising a seat cushion frame pivotally mounted to said seat cushion frame support link. ### Claim 11 (depends on 10) The system as recited in claim 10, further comprising a seat adjustment pin assembly mounted to said seat cushion frame, said seat adjustment pin assembly selectively engageable with one of a multiple of apertures within said seat cushion frame support link. ### Claim 12 A weight bench system comprising: a seat assembly; a backrest assembly; an intermediate link attached between said seat assembly and said backrest assembly; a forward seat link; an intermediate seat link pivotally mounted to said forward seat link; and a seat link pivotally mounted to said intermediate seat link and pivotally mounted to said intermediate link. ### Claim 13 (depends on 12) The system as recited in claim 12, further comprising a frame assembly, said forward seat link pivotally mounted to said frame assembly. ### Claim 14 (depends on 12) The system as recited in claim 12, further comprising a seat cushion frame support link pivotally mounted to said intermediate link and pivotally mounted to said intermediate seat link. ### Claim 15 (depends on 14) The system as recited in claim 14, further comprising a seat cushion frame pivotally mounted to said seat cushion frame support link at an axis common to said intermediate seat link. ### Claim 16 A weight bench system comprising: a seat assembly; a backrest assembly including a rear backrest link pivotally attached to a forward backrest link; a backrest adjustment pin assembly engaged with said rear backrest link; a remote handle assembly connected to said backrest adjustment pin assembly; and an intermediate link attached between said seat assembly and said forward backrest link. ### Claim 17 (depends on 16) The system as recited in claim 16, further comprising a seat adjustment pin assembly mounted to said seat assembly, said seat adjustment pin assembly selectively engageable with one of a multiple of apertures to select an angle between a seat cushion frame support link and a seat cushion frame. ### Claim 18 A method of positioning a weight bench seat assembly relative a backrest assembly comprising the steps of: articulating a backrest assembly; articulating a seat assembly in response to articulating the backrest assembly, the seat assembly defining seat pivot axis which transits both forward an aft in response to a unidirectional articulation of the backrest assembly through a range of motion; and transiting the seat pivot axis forward until the backrest assembly obtains an approximately thirty degree position then the seat pivot axis reverses and traverses aft in response to the backrest assembly increasing beyond the approximately thirty degree position. ### Claim 19 A method of positioning a weight bench seat assembly relative a backrest assembly comprising the steps of: articulating a backrest assembly; articulating a seat assembly in response to said step (A), the seat assembly defining a seat pivot axis which transits both forward and aft in response to a undirectional articulation of the backrest assembly through a range of motion; and transiting the seat pivot axis aft until the backrest assembly obtains an approximately thirty degree position then the seat pivot axis reverses and traverses forward in response to the backrest assembly continuing toward a zero degree position.
