Dampener for a vehicle seat recliner
View Patent ↗A recliner assembly for a vehicle seat having a seat back movably mounted relative to a seat bottom includes first and second frame members. The first frame member supports the seat back. The second frame member supports the seat bottom. The first frame member is pivotally attached to the second frame member and is movable between an upright position and a storage position. In the upright position, the seat back is in a generally vertical position for supporting an occupant seated on the seat. In the storage position, the seat back is positioned above the seat bottom. A damper is operatively connected between the first and second frame members. The damper dampens the movement of the first frame member relative to the second frame member when the first frame member is pivoted from the upright position to the storage position.
1. A recliner assembly for a vehicle seat having a seat back movably mounted relative to a seat bottom, said recliner assembly comprising:
a first frame member for supporting a seat back;
a second frame member for supporting a seat bottom, said first frame member pivotally attached to said second frame member and movable between an upright position wherein the seat back is in a generally vertical position for supporting an occupant seated on the seat, and a storage position wherein the seat back is positioned above the seat bottom; and
a damper operatively connected between said first and second frame members, said damper including first and second plates that are respectively connected to said first and second frame members and that slidably cooperate to dampen movement of said first frame member relative to said second frame member during only a portion of the movement from said upright position to said storage position.
2. The recliner assembly of claim 1 , wherein said recliner assembly further includes a spring member connected between said first and second frame members such that said spring member biases the seat back to its storage position.
3. The recliner assembly of claim 2 , wherein said spring member is a spiral spring.
4. The recliner assembly of claim 1 , wherein said damper utilizes sliding frictional engagement between two surfaces to provide the dampening movement of said first frame member relative to said second frame member.
5. The recliner assembly of claim 4 , wherein said damper includes a dampener operatively connected to one of said first and second plates.
6. The recliner assembly of claim 5 , further including a third plate that is fixed in position relative to said second plate, and wherein said dampener includes a pair of dampening surfaces which frictionally engage a pair of sliding surfaces of said second and third plates.
7. The recliner assembly of claim 6 , wherein said dampening surfaces are formed on opposed sides of said dampener.
8. The recliner assembly of claim 5 , wherein said dampener is made of plastic.
9. The recliner assembly of claim 5 , wherein said dampener is operatively connected to one of said first and second plates and is in selective sliding frictional engagement with the other one of said first and second plates.
10. The recliner assembly of claim 9 , wherein said dampener is molded onto said one of said first and second plates.
11. The recliner assembly of claim 9 , wherein said dampener is fastened to one of said first and second plates, and wherein said other of one of said first and second plates includes a third plate having said sliding surface in selective sliding engagement with said dampener.
12. The recliner assembly of claim 11 , wherein said dampener extends outwardly from said first plate, and wherein said third plate is spaced from said second plate by a distance less than the width of the dampener such that an interference fit exists between said second and third plates and said dampener.
13. The recliner assembly of claim 12 , wherein each of said second and third plates includes a coined edge defining a radius.
14. The recliner assembly of claim 12 , wherein said dampener includes a rounded edge defining a radius.
15. A seat assembly comprising:
a first frame member for supporting a seat back;
a second frame member for supporting a seat bottom, said first frame member supported on said second frame member for movement between first and second positions relative thereto; and
a damper including first and second plates that are respectively fixed in position relative to said first and second frame members, said first plate slidably cooperating with said second plate during only a portion of the movement of said first member from said first position to said second position relative to said second member.
16. The seat assembly of claim 15 , further including a dampener supported on one of said first and second plates, said dampener slidably cooperating with the other of said first and second plates during only a portion of the movement of said first member from said first position to said second position relative to said second member.
17. The seat assembly of claim 15 , further including a third plate that is fixed in position relative to said second plate, said first plate slidably cooperating with said second and third plates during only a portion of the movement of said first member from said first position to said second position relative to said second member.
18. The seat assembly of claim 17 , further including a dampener supported on said first plate, said dampener slidably cooperating with said second and third plates during only a portion of the movement of said first member from said first position to said second position relative to said second member.
