Dynamic hook insert for a movable seat back

1. A dynamic hook insert for a movable seat back tethered to a cabin wall, said insert comprising:

a body configured for attachment to a latch bracket on a seat back;

an elongated, generally U-shaped channel formed in said body, said channel configured to slidably receive a striker pin extending from a cabin wall; and

a stand-off extending from said body generally transversely away from said U-shaped channel for creating a bendable section in said body to dynamically absorb vibrations transferred to and from the striker pin and for automatically accommodating relative dimensional variance in the striker pin.

2. The insert of claim 1 wherein said body includes at least one mounting flange.

3. The insert of claim 2 wherein said channel includes a mouth, said bendable section including a chamfer adjacent said mouth for facilitating ingress of the striker pin.

4. The insert of claim 3 wherein said stand-off is disposed adjacent said mouth.

5. The insert of claim 3 wherein said bendable section includes a retraining strap extending generally transversely away from said U-shaped channel for operative interaction with the latch bracket.

6. The insert of claim 1 wherein said body includes a pair of spaced apart mounting flanges on one side of said channel.

7. A movable seat back assembly of the type normally tethered to a cabin wall, said assembly comprising:

a seat back having a rearward surface presenting toward a cabin wall;

a rigid latch bracket extending from said rearward surface, said latch bracket including an elongated generally U-shaped slot for receiving a striker pin anchored to the cabin wall;

a dynamic hook insert directly connected to said latch bracket, said insert including a pair of generally parallel legs spaced apart from one another and joined together at their respective upper ends, a separation between said legs forming an elongated, generally U-shaped channel lining said U-shaped slot of said latch bracket; and

at least one of said legs of said insert being generally transversely spaced from said slot of said latch bracket and comprising a resiliently bendable section dynamically movable relative to said latch bracket for absorbing vibrations transferred to and from the striker pin and for automatically accommodating relative dimensional variances in the striker pin.

8. The assembly of claim 7 further including a stand-off disposed between said bendable section and said latch bracket for maintaining said space there between.

9. The assembly of claim 8 wherein said stand-off is integrally formed on said bendable section of said insert.

10. The assembly of claim 9 wherein said insert includes at least one mounting flange on said leg opposite said resiliently bendable section.

11. The assembly of claim 10 wherein said channel includes a mouth, said bendable section including a chamfer adjacent said mouth for facilitating ingress of a striker pin.

12. The assembly of claim 11 wherein said stand-off is disposed adjacent said mouth.

13. The assembly of claim 11 wherein said bendable section includes a retaining strap extending generally transversely away from said U-shaped channel for operative interaction with said latch bracket.

14. The assembly of claim 9 wherein said insert includes a pair of mounting flanges spaced apart from one another and straddling said latch bracket.

15. The assembly of claim 14 wherein said pair of mounting flanges and said latch bracket include at least two aligned holes, and a fastener extending through said aligned holes for securely retaining said insert in an operative position relative to said latch bracket.

16. A method for reducing vibration-induced noise in the connection between a movable seat back and a cabin wall, said method comprising the steps of:

providing a latch bracket on the seat back having a U-shaped slot;

lining the slot with a polymeric insert having a complimentary U-shaped channel;

providing a striker pin on the cabin wall;

tethering the seat back to the cabin wall by slidably engaging the striker pin inside the channel; and

creating a resiliently bendable section in the insert for dynamically deflecting in the region of abutting contact with the striker pin including interposing a stand-off between the insert and the slot of the latch bracket to establish an air space between at least a portion of the insert and the slot of the latch bracket.

17. A method for reducing vibration-induced noise in the connection between a movable seat back and a cabin wall, said method comprising the steps of:

providing a latch bracket on the seat back having a U-shaped slot;

lining the slot with a polymeric insert having a complimentary U-shaped channel;

creating a resiliently bendable section in the insert for dynamically deflecting in the region of abutting contact with the striker pin;

providing a striker pin on the cabin wall;

tethering the seat back to the cabin wall by slidably engaging the striker pin inside the channel; and

locating the bendable section relative to the latch bracket with a retaining strap.
