Abstract

A seat dump assembly includes an actuator, a seat dump mechanism remote from the actuator, a mechanical seat adjustment accommodation device, a first cable connecting the actuator to the mechanical seat adjustment accommodation device and a second cable connecting the mechanical seat adjustment accommodation device to the seat dump mechanism.

First claim

What is claimed:

1. A seat dump assembly, comprising:
an actuator;
a fixed track;
a carriage displaceable along said fixed track;
a first cable connecting said actuator to said carriage;
a spool carried on said carriage;
a spool retainer;
a first biasing element biasing said carriage into a home position with said spool held in said spool retainer;
a seat dump mechanism;
a second cable connecting said spool to said seat dump mechanism; and
a second biasing element eliminating slack and winding said second cable onto said spool.

2. The seat dump assembly of claim 1 , further including a sprocket on said spool.

3. The seat dump assembly of claim 2 , further including a lug on said carriage.

4. The seat dump assembly of claim 3 , wherein manipulation of said actuator displaces said carriage along said fixed track from said home position to a seat dump position wherein said spool is released from said spool retainer and said sprocket engages said lug (a) locking said spool against rotation, (b) activating said seat dump mechanism and (c) dumping a seat back.

5. The seat dump assembly of claim 4 , wherein said fixed track includes a base supporting a first guide element and a second guide element.

6. The seat dump assembly of claim 5 , wherein said first guide element extends along a first axis and said second guide element extends along a second axis wherein said first axis is parallel to said second axis.

7. The seat dump assembly of claim 6 , wherein said spool retainer includes a first catch and a second catch.

8. The seat dump assembly of claim 7 , wherein said first catch is outboard said first guide element on said base and said second catch is outboard said second guide element on said base.

9. The seat dump assembly of claim 8 , wherein said carriage includes a first follower receiving said first guide element and a second follower receiving said second guide element.

10. The seat dump assembly of claim 9 , wherein said carriage includes a cradle capturing a first end of said spool and a second end of said spool.

11. The seat dump assembly of claim 10 , wherein said first catch engages said first end of said spool and said second catch engages said second end of said spool when said carriage is in said home position.

12. The seat dump assembly of claim 11 , further including a boss on said fixed track retaining said first cable.

13. The seat dump assembly of claim 1 , further including a spool locking mechanism.

14. A seat dump assembly, comprising:
an actuator;
a seat dump mechanism remote from said actuator;
a mechanical seat adjustment accommodation device;
a first cable connecting said actuator to said mechanical seat adjustment accommodation device; and
a second cable connecting said mechanical seat adjustment accommodation device to said seat dump mechanism.

15. A method of dumping a seat back by use of a mechanical seat dump assembly, comprising:
connecting a remote actuator to a seat dump mechanism through a mechanical seat adjustment accommodation device; and
dumping the seat back in response to manipulation of said remote actuator.

16. The method of claim 15 , further including displacing a spool of said mechanical seat adjustment accommodation device from a home position to a seat dump position.

17. The method of claim 16 , further including cradling said spool in a carriage, connecting said remote actuator to said carriage by use of a first cable and connecting said spool to said seat dump mechanism by use of a second cable.
