Seat assembly for a vehicle
View Patent ↗A seat assembly for a vehicle includes a seat bottom and a seatback. The seatback includes a seatback frame and is selectively rotatable relative to the seat bottom from an upright position to a forward position. A seatbelt assembly includes a retractor coupled to the seatback frame and a belt selectively extendable from and retractable to the retractor. A first end of the belt is disposed in the retractor. A guide is coupled to the seatback frame and defines an orifice with the belt slideably extending through the orifice. The retractor and the guide are fixed relative to the seatback frame and the second end of the belt is fixed to the seatback frame. The retractor, the guide, and both ends of the belt rotate from the upright position to the forward position in response to a force exerted on the seatback frame during rapid deceleration of the seat assembly.
1. A seat assembly for a vehicle, said seat assembly comprising:
a seat bottom;
a seatback coupled to said seat bottom and having a seatback frame, said seatback frame having a U-shaped cross-section defined by a first edge extending along an axis and a second edge spaced from said first edge and extending along said axis and a surface extending from said first edge to said second edge defining a channel extending along said axis between said first edge and said second edge;
a seatbelt assembly including a retractor and a belt having a first end disposed in said retractor with said belt extending from said retractor, said belt extending along said axis in said channel and being selectively extendable from and retractable to said retractor;
a guide spaced from said retractor and coupled to said seatback frame and defining an orifice with said belt slideably extending from said channel through said orifice; and
a cover having an inner surface defining a cavity receiving said seatback frame with said inner surface extending from said first edge to said second edge of said seatback frame for enclosing said belt in said channel between said retractor and said guide.
2. The seat assembly as set forth in claim 1 wherein said inner surface of said cover contacts said first and second edges of said seatback frame.
3. The seat assembly as set forth in claim 1 wherein said guide is selectively moveable between fixed positions along said axis.
4. The seat assembly as set forth in claim 1 wherein said cover defines an opening extending along said axis with said guide selectively moveable along said opening and with said belt extending from said guide through said opening.
5. The seat assembly as set forth in claim 1 wherein said seatback frame defines a track extending along said axis and a plurality of indentations along said track and said guide includes a slider slideably engaging said track and a shaft selectively engageable with said indentations for fixing the guide to said track.
6. The seat assembly as set forth in claim 1 wherein said seatback frame is rotatable relative to said seat bottom from an upright position to a forward position.
7. The seat assembly as set forth in claim 1 wherein said seatback frame is further defined as at least one tower extending upwardly from said seat bottom.
8. The seat assembly as set forth in claim 1 wherein said seatback frame is further defined as at least towers spaced from each other along said seat bottom with said cover rigidly coupling said towers to each other with said towers and said cover rotating from an upright position toward a forward position.
9. The seat assembly as set forth in claim 1 further comprising an energy absorbing device coupled to said seatback for selectively allowing movement of said towers relative to said seat bottom to absorb energy in response to forces exerted on said seatback.
10. The seat assembly as set forth in claim 9 wherein said energy absorbing device includes an energy absorbing member that deforms to absorb energy as said towers move relative to said seat bottom and a stopping member that selectively limits movement of said towers relative to said seat bottom.
11. A seat assembly for a vehicle, said seat assembly comprising:
a seat bottom;
a seatback coupled to said seat bottom and having at least two towers spaced from each other, said towers each having a U-shaped cross-section defined by a first edge extending along an axis and a second edge spaced from said first edge and extending along said axis and a surface extending from said first edge to said second edge defining a channel extending along said axis between said first edge and said second edge;
a seatbelt assembly including a retractor and a belt having a first end disposed in said retractor with said belt extending from said retractor, said belt extending along said axis in said channel of one of said towers; and
a cover having an inner surface defining a cavity receiving said towers with said inner surface extending from said first edge to said second edge of said towers for enclosing said belt along said channel.
12. The seat assembly as set forth in claim 11 wherein said inner surface of said cover contacts said first and second edges of said towers.
13. The seat assembly as set forth in claim 11 wherein said cover defines an opening extending along said axis with said belt extending from said channel through said opening.
14. The seat assembly as set forth in claim 11 wherein said towers are moveable relative to said seat bottom from an upright position to a forward position.
15. The seat assembly as set forth in claim 14 further comprising an energy absorbing device coupled to said seatback for selectively allowing movement of said towers relative to said seat bottom to absorb energy in response to forces exerted on said seatback.
16. The seat assembly as set forth in claim 15 wherein said energy absorbing device includes an energy absorbing member that deforms to absorb energy as said towers move relative to said seat bottom.
17. The seat assembly as set forth in claim 16 wherein said energy absorbing device includes a stopping member that selectively limits movement of said towers relative to said seat bottom.
18. A seat assembly for a vehicle, said seat assembly comprising:
a seat bottom;
a seatback coupled to said seat bottom and having at least two towers spaced from each other, said towers each having a U-shaped cross-section defining a channel,
said towers being moveable relative to said seat bottom in response to forces exerted on said seatback;
a seatbelt assembly including a retractor and a belt having a first end disposed in said retractor with said belt extending from an retractor, said belt extending along said axis in said channel of one of said towers;
a cover having an inner surface defining a cavity receiving said towers with said inner surface extending across said channel of said towers for enclosing said belt in said channel; and
an energy absorbing device coupled to said seatback for selectively allowing movement of said towers relative to said seat bottom to absorb energy in response to the forces exerted on said seatback.
19. The seat assembly as set forth in claim 18 wherein said energy absorbing device includes an energy absorbing member that deforms to absorb energy as said towers move relative to said seat bottom.
20. The seat assembly as set forth in claim 18 wherein said energy absorbing device includes a stopping member that selectively limits movement of said towers relative to said seat bottom.
21. The seat assembly as set forth in claim 18 wherein said cover defines an opening extending along said channel with said belt extending from said channel through said opening.
22. The seat assembly as set forth in claim 18 wherein said towers are rotatable relative to said seat bottom from an upright position to a forward position.
