Abstract

An adjustable chair support system includes a first seat back support member spaced from a second seat back support member, and a seat back tensioning assembly that extends between the first and second seat back support members. The seat back tensioning assembly includes a carrier coupled to the first seat back support member, the carrier including an adjustable tension member and a first guide member, a pair of second guide members coupled to the second seat back support member, and a cable extending from the adjustable tension member into engagement with one of the pair of second guide members, with the first guide member, with the other of the pair of second guide members, and then returning to the adjustable tension member.

Claims (25)

1. An adjustable chair support system comprising:

a first seat back support member spaced from a second seat back support member;

a seat back tensioning assembly extending between the first and second seat back support members, the seat back tensioning assembly including:

a carrier coupled to the first seat back support member, the carrier including an adjustable tension member and a first guide member;

a pair of second guide members coupled to the second seat back support member; and

a cable extending from the adjustable tension member into engagement with one of the pair of second guide members, with the first guide member, with the other of the pair of second guide members, and then returning to the adjustable tension member.

2. The adjustable chair support system of claim 1 , wherein the adjustable tension member is configured to adjust a tension of the cable.

3. The adjustable chair support system of claim 1 , wherein a length of the cable extending between the adjustable tension member and one of the pair of second guide members decreases in response to actuation of the adjustable tension member in a first direction.

4. The adjustable chair support system of claim 3 , wherein actuation of the adjustable tension member in the first direction includes rotating a portion of the adjustable tension member.

5. The adjustable chair support system of claim 3 , wherein the length of the cable extending between the adjustable tension member and one of the pair of second guide members increases in response to actuation of the adjustable tension member in a second direction.

6. The adjustable chair support system of claim 5 , wherein the actuation of the adjustable tension member in the second direction includes sliding the portion of the adjustable tension member along an axis of rotation of the portion of the adjustable tension member.

7. The adjustable chair support system of claim 6 , wherein axis of rotation is perpendicular to the carrier.

8. The adjustable chair support system of claim 1 , wherein the seat back tensioning assembly is coupled to the first seat back support member by a first depth adjustment bracket.

9. The adjustable chair support system of claim 8 , wherein the first depth adjustment bracket defines a channel that is configured to receive a fastener, the fastener is configured to couple the first depth adjustment bracket to the first seat back support member.

10. The adjustable chair support system of claim 9 , wherein the first depth adjustment bracket is configured to slide relative to the fastener along the channel to adjust a depth of the seat back tensioning assembly relative to the first seat back support member.

11. The adjustable chair support system of claim 10 , wherein the first depth adjustment bracket is coupled to a first width adjustment bracket, the first width adjustment bracket is coupled to the first seat back support member.

12. The adjustable chair support system of claim 11 , wherein the first width adjustment bracket is configured to rotate with respect to an axis defined by the first seat back support member.

13. The adjustable chair support system of claim 12 , wherein the first width adjustment bracket defines a channel that is configured to receive a portion of the first seat back support member.

14. The adjustable chair support system of claim 13 , wherein the first width adjustment bracket is configured to slide relative to the first seat back support member to adjust a height of the seat back tensioning assembly relative to the first seat back support member.

15. The adjustable chair support system of claim 1 , wherein the seat back tensioning assembly is coupled to the first seat back support member by a first width adjustment bracket.

16. The adjustable chair support system of claim 15 , wherein the first width adjustment bracket is configured to rotate with respect to an axis defined by the first seat back support member.

17. The adjustable chair support system of claim 15 , wherein the first width adjustment bracket defines a channel that is configured to receive a portion of the first seat back support member.

18. The adjustable chair support system of claim 17 , wherein the first width adjustment bracket is configured to rotate with respect to the portion of first seat back support member that is received by the channel to adjust a width of the seat back tensioning assembly.

19. The adjustable chair support system of claim 17 , wherein the first width adjustment bracket is configured to slide relative to the first seat back support member to adjust a height of the seat back tensioning assembly relative to the first seat back support member.

20. The adjustable chair support system of claim 1 , wherein the adjustable chair support system is incorporated with a wheelchair.
