Dual motion sloped floor recline mechanism for a theater seat
Provided is a dual motion recline mechanism for a seating assembling and seating assembly including the same. The seating assembly provides a user with the ability to both tilt the seat member so as to save space and the comfort of a back member capable of reclining. The recline mechanism includes a seat frame carrier assembly, a seat pivot pin, a seat carrier chassis plate, a rear pivot link, a chassis mounting plate, a back frame assembly, and a linear actuator connected by various pivotal, sliding or fixed connections. The linear actuator is remotely situated including for example behind the back frame assembly or under an arm rest. Optional elements include a seat front guide block, a seat front guide rod, back frame guide block and a back guide pin. The seating assembly may be a theater seat. The seating assembly may be mounted on a flat or sloped surface.
1. A dual motion recline mechanism for a seat assembly comprising:
a seat frame assembly wherein said seat frame assembly is configured to pivot between an upright position and a horizontal down position;
a seat carrier chassis plate operatively connected to said seat frame assembly by a pair of seat pivot pins, wherein said seat carrier chassis plate provides support for said seat frame assembly and is configured to allow the movement of said seat frame assembly;
a seat front guide rod;
a chassis mounting plate, wherein said chassis mounting plate is connected to said seat frame assembly by said seat front guide rod;
a linear actuator;
a pair of rear pivot links wherein each of said pair of rear pivot links is operatively connected to said chassis mounting plate via an upper end of each of said pair of rear pivot links, to said seat carrier chassis plate via a center of each of said pair of rear pivot links and to said linear actuator via a lower end of each of said pair of rear pivot links; and
a back frame assembly operatively attached to said seat carrier chassis plate and to said linear actuator,
wherein said linear actuator is configured to allow said seat carrier chassis plate to pull said back frame assembly downward and forward and to allow said pair of rear pivot links to rotate and pull said seat carrier chassis plate in a down and forward direction thereby pulling said seat frame assembly forward; and
wherein said chassis mounting plate is further connected to said seat frame assembly by said pair of rear pivot links.
2. The dual motion recline mechanism of claim 1 , wherein said seat frame assembly is connected to the said seat carrier chassis plate by a pivotal connection.
3. The dual motion recline mechanism of claim 1 , wherein said back frame assembly is attached to said seat carrier chassis plate by a pivotal connection.
4. The dual motion recline mechanism of claim 1 , wherein said linear actuator is situated behind said back frame assembly.
5. The dual motion recline mechanism of claim 1 , wherein said linear actuator is situated under an arm rest attached to said seat assembly.
6. The dual motion recline mechanism of claim 1 , wherein said linear actuator is attached to said pair of rear pivot links.
7. The dual motion recline mechanism of claim 1 , further comprising a seat front guide block attached to said chassis mounting plate so as to provide further support to said seat carrier chassis plate, wherein said seat front guide block and said seat front guide rod are connected by a sliding contact connection.
8. The dual motion recline mechanism of claim 1 , wherein the back frame assembly comprises a back mounting bracket attached to the seat carrier chassis plate.
9. The dual motion recline mechanism of claim 1 , wherein said linear actuator is operatively connected to a back mounting bracket by a motor drive link.
10. A seat assembly comprising the reclining mechanism of claim 1 .
11. The seat assembly of claim 10 , wherein said seat assembly is a theater seat.
12. The seat assembly of claim 10 further comprising:
a seat member comprising said seat frame assembly, configured to operate between an upright position and a horizontal down position;
a pair of side panels operatively connected to and on opposite sides of said seat member;
a back member disposed between and operatively connected to said pair of side panels, wherein said back member comprises said back frame assembly and is configured to pivot between a closed upright position and an open reclined position.
13. The seat assembly of claim 10 , wherein said seat assembly is configured to be mounted on a sloped floor.
14. The seat assembly of claim 13 , further comprising an adjustable leg allowing said seat assembly to be mounted on a sloped floor.
15. The seat assembly of claim 14 , wherein said adjustable leg is a bolt-on leg, a screw-type leg, a clamp-type leg, a linkage support or a threaded leg.
16. The seat assembly of claim 10 , wherein said seat assembly is configured to be mounted on a flat leveled floor.
17. The dual motion recline mechanism of claim 1 , wherein said seat carrier chassis plate is operatively connected to said seat frame assembly by said pair of seat pivot pins, wherein said pair of seat pivot pins are pivotal connections allowing said seat frame assembly to pivot.
18. The dual motion recline mechanism of claim 1 , further comprising a fixed base attached to said chassis mounting plate.
19. The dual motion recline mechanism of claim 1 , further comprising a back frame guide block attached to said back frame assembly.
