Abstract

The invention provides a seat clip ( 1 ) for attaching a seat to a frame of a chair, comprising an upper portion ( 2 ) arranged to be attached to the seat ( 6 ), a lower portion ( 3 ) comprising a latching element ( 5 ) arranged to be reversibly attached to the frame ( 7 ) by positive locking, and an intermediate portion ( 4 ) connecting the upper portion ( 2 ) to the lower portion ( 3 ) and being flexible, such that the seat clip can be deformed when pressure is applied to the intermediate portion ( 4 ) and/or the lower portion ( 3 ) in order to attach the latching element ( 5 ) to the frame ( 7 ).

First claim

The invention claimed is:

1. A seat clip for attaching a seat to a frame of a chair, comprising:
an upper portion arranged to be attached to the seat;
a lower portion comprising a latching element arranged to be reversibly attached to the frame by positive locking; and
an intermediate portion connecting the upper portion to the lower portion and being flexible, such that the seat clip can be deformed when pressure is applied to the intermediate portion and/or the lower portion in order to attach the latching element to the frame;
wherein the seat clip has a substantially S-shape from the upper portion to the lower portion.

2. Seat clip according to claim 1 , wherein the latching element comprises a first curved portion.

3. Seat clip according to claim 2 , wherein the intermediate portion comprises a second curved portion, which is curved in the same direction as the first curved portion.

4. Seat clip according to claim 1 , wherein the upper portion comprises at least one protrusion arranged to be inserted into at least one corresponding opening in the underside of the seat to establish a positive and/or non-positive locking between the seat clip and the seat.

5. Seat clip according to claim 4 , wherein a first and a second of at least two protrusions have different outer shapes and/or dimensions.

6. Seat clip according to claim 4 , wherein the at least one protrusion comprises a flexible tongue-like element extending laterally from the at least one protrusion.

7. Seat clip according to claim 1 , wherein the intermediate portion further comprises a grip arranged for pressing the clip towards the seat and/or the frame when attaching the seat clip to the seat and/or the frame, and for pulling the seat clip away from the seat and/or the frame when detaching the seat clip from the seat and/or the frame.

8. Seat clip according to claim 1 , wherein the seat clip is integrally formed.

9. Seat clip according to claim 1 , wherein the seat clip is made from a flexible material, in particular a plastic, in particular polyoxymethylene, POM.

10. A chair comprising:
a seat;
a frame; and
at least one seat clip comprising:
an upper portion arranged to be attached to the seat;
a lower portion comprising a latching element arranged to be reversibly attached to the frame by positive locking; and
an intermediate portion connecting the upper portion to the lower portion and being flexible, such that the seat clip can be deformed when pressure is applied to the intermediate portion and/or the lower portion in order to attach the latching element to the frame;

wherein the at least one seat clip is attached via its upper portion to the seat,
wherein the at least one seat clip is attached via its lower portion to the frame by positive locking, and
wherein the at least one seat clip has a substantially S-shape from the upper portion to the lower portion.

11. Chair according to claim 10 ,
wherein the seat comprises at least one opening;
wherein the upper portion of the at least one seat clip comprises at least one protrusion; and
wherein the at least one seat clip is attached to the seat via positive and/or non-positive locking by inserting the at least one protrusion into the at least one opening.

12. Chair according to claim 10 ,
wherein the frame comprises a groove; and
wherein the at least one seat clip is attached to the frame by interlocking the latching element with the groove.

13. Chair according to claim 11 , wherein the at least one opening is a through-hole or a blind hole.

14. Chair according to claim 11 ,
wherein the at least one opening comprises at least one notch or groove along its inner wall; and
wherein the at least one protrusion is formed such that it establishes a positive lock with the at least one notch or groove when the upper portion of the seat clip is inserted into the at least one opening.

15. A method of assembling a chair according to claim 10 , comprising the steps of:
attaching the at least one seat clip via its upper portion to the seat;
arranging the frame and the seat into a predetermined relative position; and
applying pressure to the intermediate and/or lower portion of the at least one seat clip such that the latching element engages with the frame to provide positive locking.
