Weightlifting bench with adjustable headrest
A weight bench system includes an adjustable headrest assembly. The adjustable headrest assembly is movable from a position flat with a backrest assembly to a multitude of articulated positions. To reset the headrest assembly back to the flat position, the headrest assembly is articulated to a fully articulated position, then returned to the flat position.
1. An adjustable headrest assembly for a weight bench system comprising:
a guide plate which defines a guide plate opening with a first side which defines at least one support detent and a second side opposite said first side; and
a hanging lock pin which extends through said guide plate opening, said hanging lock pin engageable with said at least one support detent, said hanging lock pin spring loaded to alternate toward either said first side or said second side as the lock pin passes over center.
2. The assembly as recited in claim 1 , wherein said guide plate opening includes an upper side sloped downward toward said first side.
3. The assembly as recited in claim 1 , wherein said guide plate opening includes a lower side sloped downward toward said first side.
4. The assembly as recited in claim 3 , wherein said lower side is sloped downward into a support detent.
5. The assembly as recited in claim 1 , wherein said guide plate opening defines a continuous inner perimeter.
6. A weight bench system comprising:
a backrest assembly which supports a generally planar backrest cushion; and
a headrest assembly which supports a generally planar headrest cushion articulatably mounted to said backrest assembly, said headrest cushion at least partially recessed into said backrest cushion, said headrest assembly movable between a flat position relative to said backrest assembly and an angled position relative to said backrest assembly.
7. The system as recited in claim 6 , further comprising:
a seat assembly; and
an intermediate link attached between said seat assembly and said forward backrest link.
8. The system as recited in claim 6 , wherein said headrest assembly further comprises:
a guide plate mounted to said backrest assembly, said guide plate defines a guide plate opening with a first side which defines at least one support detent and a second side opposite said first side;
a headrest cushion frame pivotally mounted to said backrest assembly; and
a hanging lock pin which pivotally mounted to said headrest cushion frame, said hanging lock pin located through said guide plate opening, said hanging lock plate engageable with said at least one support detent.
9. The system as recited in claim 8 , wherein said headrest cushion frame is biased toward said flat position.
10. The system as recited in claim 8 , further comprising a spring mounted to said headrest cushion frame and said hanging lock pin, said hanging lock pin spring loaded to alternate toward either said first side or said second side as the lock pin passes over center.
11. The system as recited in claim 8 , wherein said guide plate opening defines a continuous inner perimeter.
12. A method of positioning a weight bench seat assembly relative a backrest assembly comprising the steps of:
(A) articulating a backrest assembly;
(B) 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 unidirectional articulation of the backrest assembly through a range of motion.
13. A method as recited in claim 12 , wherein said step (B) further comprising the step of:
(a) 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.
14. A method as recited in claim 12 , wherein said step (B) further comprising the step of:
(a) 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.
15. The system as recited in claim 1 , wherein said hanging lock pin extends from a headrest assembly pivotally mounted to a backrest assembly, said headrest assembly supports a generally planar headrest cushion.
16. The system as recited in claim 13 , wherein said headrest assembly is movable between a multiple of angled positions, each of said positions defined by a support detent.
17. The system as recited in claim 13 , wherein said headrest assembly is movable between a zero (0) degree position, an eight (8) degree position, and a twelve (12) degree position, each of said positions, defined by a support detent.
