Description

Folding chair

The invention relates to a folding chair, comprising two front legs and two rear legs that support a seat element on their upper side for supporting a user of the folding chair, the front legs mutually, the rear legs mutually, and in each case situated on the same side of the folding chair front and rear legs are mutually connected by scissor constructions that consist of two scissor arms intersecting and pivotally connected at the point of intersection, which scissor arms all with a first mutually corresponding end can be pivoted but not slidable with the respective front and rear legs .are connected.

A folding chair of this type is known from U.S. Pat. No. 6,247,749. With this known folding chair, the upper ends of the front legs end at the upper ends of the scissor arms. The hind legs, in the unfolded position of the folding chair, extend beyond the upper ends of the scissor arms to form a backrest. Although this known folding chair is handy in its use, it is less suitable for very small children, since this known folding chair provides, in addition to a support for the seat, only a support for the back of a user.

It is an object of the present invention to provide an improved folding chair of the type mentioned in the preamble.

According to the present invention, this object is achieved by the fact that, in the case of a folding chair of the type mentioned in the preamble, the front legs and the rear legs are provided at their upper ends with pivotable extensions which are pivotable between a substantially parallel fold-in position extending to the relevant leg and a deployment position extending substantially in line with the relevant leg, the 1024134 _____

With the longer length of the extensions of the hind legs, a backrest can be realized which provides good support to a user, for example a small child.

In another embodiment of the folding chair according to the invention, it is ensured that the strip of material connecting the extensions of the front legs is provided with at least one passage for the legs of a user. For example, it is possible that the relevant strip of material has two adjacent passages for one leg each. As a result, a very stable sitting position can be provided, in particular for a small child.

Various types of materials can be used for the material strips, but it is preferred that the material strips are made of a flexible material, such as, for example, textile strips or the like. Such flexible material strips allow the hinge movement of the extensions in a simple manner, without the seat element having to be detached from these extensions. If the material strips consist of a non-flexible material, it is generally necessary to separate them from the extensions prior to the hinge movement.

A special embodiment of the folding chair according to the invention is also mentioned, wherein the scissor constructions are of such a nature that the legs in the folded position of the folding chair run substantially parallel, but diverge downwards in the unfolded position of the folding chair . Because in the unfolded position of the folding chair the legs thereof diverge downwards, a larger base surface area of the folding chair is, as it were, obtained, so that its stability is increased. This can be of particular importance when the folding chair is used by a, often mobile, small child.

Can be slidably connected to the respective front and rear legs (see Fig. 2a, pivot points 13).

In the position shown in Fig. 1, the folding chair is in an unfolded position, wherein the extensions 8-11 of the legs 1-4 assume a so-called folding position, in which they extend substantially in line with the respective legs . Here, at the location of these extensions 8-11, there is a seat element consisting of a bottom part 14, a back part 15, two side parts 16 and 17 and an advantage 18 that defines two openings 19 and 20. The bottom part 14 is intended to support the seat of a user (for example a small child), while the back part 15 will of course provide a support for the back. The side parts 16 and 17 prevent lateral movement of the user, while the openings 19 and 20 are intended for allowing the legs of the user to pass.

As is clearly visible in Fig. 1, the legs 1-4 range from top to bottom. As a result, the folding chair has a stable position.

The lower ends of the scissor arms 6, 7 are connected to sliding parts 21 which can slide up and down along the relevant legs.

Fig. 2a shows the fully folded position of the folding chair (the seating element is not shown).

The legs 1-4 are close to each other in a substantially parallel position, while the scissor arms 6,7 are pivoted about their respective pivot point 5 and the sliding parts 21 are slid downwards along the respective legs. The extensions 8-11 (extension 11 is not visible) are pivoted outwardly about their hinges 12 to a position in which they extend substantially parallel to the respective legs 1-4. In the folded position shown in Fig. 2, the folding chair has a compact configuration.

The seat element can be made from various materials, but preferably from textile. The movement of the scissor structures can be limited by stops (not shown) cooperating with the sliding parts 21 on the respective legs.

The invention is not limited to the embodiment described above, which can be varied in many ways within the scope of the invention as defined by the claims.
