Abstract

A seat device has a seat surface 1 and two support surfaces 5 for the lower legs. These support surfaces 5 preferably slope down from the front region of the seat device in the direction of its rear region. To permit adaptation to different body sizes and/or table heights, the seat device is provided, in its lower region serving for support on the ground, with a separating plane 8 extending approximately horizontally. There is a releasable connection between the two base parts of the seat device which are separated by this plane. <IMAGE>

Description

SPECIFICATION Seat device The invention relates to a seat device with a seat surface and two support surfaces located lower relative to the latter, for the lower legs angled backwards in respect of the thighs, the support surfaces preferably sloping down from the front region of the seat device in the direction of its rear region.

The aim of the invention is to design such a seat device with simple means, in such a way that it can be adapted quickly to different body sizes or differenttable heights.

To achieve this object, the invention envisages, in a seat device of the type mentioned in the introduction, that the seat device be divided into two seat parts in its lower region, a releasable connection, for example a screw connection, existing between theses two seat parts. As a result, it is possible not only to adapt to different body sizes (adults - children), but also to change the vertical position of the seat surface, for example depending on whether the seat device is to be used at a relatively high or relatively low table.

Further details emerge from the exemplary embodiment of the invention which is described below and illustrated in the drawing, in which: Figure 1 shows a side view of a seat device according to the invention.

Figure 2 shows an end view in the direction of the arrow 11 in Figure 1.

The seat device has a seat surface 1, the substructure 2 of which can be made wing-shaped and is supported by a web-like centre part 3. This part 3 merges into an upper base 4 which has the two sup port surfaces 5 extending in a longitudinal direction.

The point of transition 5' between the centre part 3 and the upper base 4 can be curved in a cross section perpendicular to the longitudinal centre plane 7 (see Figure 2).

The support surfaces 5 preferably slope from the front 6 to the rear 7, so that, in the seating position indicated by dot-and-dash lines, there is a sufficiently large angle between the thigh and the lower leg of the seated person. The seat surface 1 can be slightly curved (not shown).

In its lower region the seat device is divided by a separating plane 8 into the upper base part 4 already described and a lower base part 9, which can be fastened to one another by means of a releasable connection, for example a screw connection 10. The base parts 4, 9 are preferably congruent to one another and the elements of the releasable connection on the two base parts 4, 9 are matched to one another in their dimensions and positions in space.

As a result, on the one hand, a tilt-proof retention of the seat device on the ground is ensured, but, on the other hand, the lower part does not project laterally beyond the floor area ofthe seat device, which would be troublesome when it is used. The seat device can consist of any material which allows such sitting. Thus, the material used can be a foam which, though having a certain elasticity, nevertheless also has sufficient stiffness.

1. Seat Device with a seat surface and two support surfaces located lower relative to the latter, for the lower legs angled backwards in respect of the thighs, the support surfaces preferably sloping down from the front region of the seat device in the direction of its rear region, characterised in that in its lower region serving for support on the ground, the seat device has a separating plane (8) extending approximately horizontally, and in that there is a releasable connection between the two base parts (4, 9) separated as a result.

2. Seat Device according to Claim 1, characterised in that a screw connection (10) serves as a releasable connection.

3. Seat Device according to Claim 1 or 2, characterised in that the base parts (4, 9) are congruent to one another at least on their abutting surfaces.

4. Seat Device substantially as described with reference to and as illustrated in the accompanying drawings.
