Abstract
Description
- The invention relates to a folding chair comprising a seat and a backrest that are hinge-connected to each other, wherein the chair has a folded position, wherein the seat and the backrest are substantially located adjoining each other, and an unfolded position, wherein the seat and the backrest extend out at an angle in relation to each other, and wherein the backrest comprises a lumbar support section with a section that bulges outward in the direction facing the seat. The chair is for example a garden chair or camping chair.
- A folding chair with an ergonomically shaped backrest is known from
EP 689784 - An objective of the invention is to provide an improved folding chair.
- This objective is achieved in that the backrest comprises a seating space section underneath the lumbar support section, and in that the seating space section is concave in the direction facing the seat. By "underneath" the lumbar support section, the side of the lumbar support section facing the seat is intended. In other words the seating space section of the backrest is located at the end of the backrest between the seat and the lumbar support section.
- The lumbar support section extends in the transverse direction from the backrest. The seating space section is underneath the lumbar support section. The behind of a person seated in the chair according to the invention is partly accommodated in the concave seating space section. Surprisingly, because of this, the lumbar support section appears to fit well with the back of different persons of varying height and build. By using the seating space section, the lumbar support section becomes positioned correctly for different persons - even though each person's back has a different shape. This pleasant seating comfort makes the chair attractive for many people.
- In one embodiment, the seating space section has a radius of curvature, R1 of 150-250 mm, for example of approximately 200 mm. It is also possible for the convex part of the lumbar support section to have a radius of curvature, R2 of 70-170 mm, for example of approximately 120 mm. This is favorable for comfort when seated.
- It is possible that, in the unfolded position, the seat forms a seating area, wherein the convex part of the lumbar support section has a top that is determined by the point protruding furthest outward in the direction of the seat, and wherein the distance d1, viewed perpendicular to the seating area, between the seating area and the top is 180-250 mm, for example approximately 195. The makes the chair according to the invention particularly comfortable.
- In one embodiment, the lumbar support section comprises a lower end that is connected to the concave seating space section, wherein the lumbar support section, at the end facing away from the seating space section, is provided with an uppermost part that is concave in the direction facing the seat, and wherein the end of the uppermost part forms the upper end of the lumbar support section at the side facing away from the seating space section, and wherein the lumbar support section has a height that is determined by the distance between the lower end and the upper end thereof, and wherein such height is 200-300 mm, for example approximately 250 mm. This improves the comfort of the chair when seated.
- For example, the concave uppermost part has a radius of curvature, R3, of 200-300 mm, for example approximately 250 mm. A smooth transition into the backrest is formed in this manner.
- Otherwise, the concave seating space section and the convex section of the lumbar support section can be connected directly to each other. It is also possible for the lumbar support section to have a straight lowermost part underneath the convex part, which is connected to the concave seating space section. Additionally, the backrest can comprise a straight section underneath the concave seating space section. The lumbar support section can furthermore be provided with a straight transition part located between the convex part and the uppermost concave part. The backrest normally has a substantially straight backrest section that is connected to the lumbar support section at the side of it that faces away from the seating space section.
- In one embodiment, the backrest is provided with a frame comprising two side bars, which extend substantially parallel and at a distance from each other, as well as a fabric support member attached to the side bars, and wherein the lumbar support section and the concave seating space section are formed in each side bar. The side bars are therefore formed with the sections and/or parts and/or radii of curvature as described above. The fabric support substantially follows the shape of the side bars.
- In the unfolded position it is possible for the seat to form a seating surface, wherein the support member has a lower edge that is spaced from the seating surface, and wherein the distance between the lower edge and the seating surface, viewed perpendicular to the seating surface, is 70-170 mm, for example 120 mm. An extra seating space is formed in this manner for the behind, thus increasing comfort when seated.
- Also the angle between the seating surface and the backrest can be greater than 95°, preferably greater than 100°. For example, with the chair in the unfolded position the backrest can be adjusted to different angles in relation to the seating area, wherein the angle between the seating area and the backrest, in the most vertical position of the backrest, is greater than 95°, preferably greater than 100°. The chair is particularly suitable for use as a garden chair or a camping chair in this manner.
- In one embodiment, the chair is provided with chair legs each comprising an underside that said undersides being aligned in a horizontal plane, when the chair is unfolded, and wherein the seating area is arranged at an angle of 5-25° in relation to said horizontal plane. Such a slight rearward leaning angle makes the chair particularly suitable for use as a garden chair or a camping chair.
