Definitions
- the invention relates to a chair with a resiliently supported on a frame, movable seat plate and a backrest.
- Office chairs have reached a high level in terms of functionality, ergonomic qualities and durability in recent years. Naturally, this has always resulted in more complex, heavier and also more expensive constructions.
- the object of the invention is to create a simple, light, inexpensive to manufacture chair which, despite the structural simplification, offers good seating comfort and meets the ergonomic requirements.
- the seat plate is made of thin, flexible plate material which is guided downward in a U-shape around the front edge of the seat plate and is firmly clamped to the frame.
- plywood or various plastic materials can be considered as a flexible, elastic plate material of this type.
- At least one link pivotably connected to the frame is expediently provided between its rear area and the frame, which is firmly connected to the seat plate in the rear area of its underside and causes the seat plate at its rear area compresses along a predetermined path, and that the seat plate is forced to bend essentially S-shaped when it is compressed, which results in an ergonomically favorable adaptation to the body shape of the user.
- the backrest preferably also consists of an elastic, plate-shaped material. It is preferably connected to the rear end of the seat plate.
- a guide is preferably attached, on which the backrest is guided in a vertically adjustable manner.
- Fig. 1 is a schematic perspective partial view of a chair according to the invention
- FIG. 1 shows a chair according to the invention with a vertical column 10 forming the frame with a bogie (not shown) at the lower end, a seat plate 12 and a backrest 14 and two armrests 16 and 18.
- a bogie not shown
- the column 10 another frame, for example a frame with four legs may be provided.
- the seat plate 12 consists of a thin, flexible plate material which is bent around the front edge of the seat plate 12 in a U-shape downwards and firmly clamped in the upper region of the column 10 with its lower, again rearward-facing section 22 is. This results in a firm but resilient support of the seat plate 12 due to the flexibility of the plate material of the seat plate 12 when the chair is used by one person.
- two parallel links 24 are provided in the example shown, which are pivotably mounted in an axis 26 at the upper end of the column 10 and from there are guided obliquely backwards and upwards.
- These links 24 are rigidly attached under the rear end region of the seat plate 12, as can be seen in more detail in FIG. 2. In this way, the rear end of the seat plate 12 is guided precisely when deflected, and the rest of the seat plate 12 is also forced by the rigid connection to the links 24 to an essentially S-shaped deformation, which is ergonomically and anatomically known has proven particularly favorable.
- This S-shaped deformation is based on the fact that at least the rear edge area of the seat plate always runs parallel to the handlebars during the downward movement of the handlebars 24, and the plate thus only rises S-shaped to the height of the front edge in the central area in the rearward lowered position .
- Connection fittings 2 are indicated in FIG. 2, which bring about a rigid connection of the links 24 with the rear end region of the seat plate 12 over a certain length.
- a vertical guide device 30 is rigidly attached, which receives the backrest 14 vertically displaceable, so that a separate height adjustment of the backrest 14 is made possible. The size of the user of the chair can thus be taken into account.
- the plate-shaped material of the seat plate 12 and also the backrest 14, which can be, for example, plywood or a suitable plastic with corresponding elasticity, can be increased by numerous slots in the longitudinal direction of the chair or vertical slots 32, 34 in order to increase the flexibility , parallel, unmarked stripes. This streak formation immediately increases the flexibility in the transverse direction of the seat plate 12 or backrest 14, thus improving adaptation to the body shape of the user.
- the invention makes it possible to use the inherent elasticity of the panel material, in particular a plywood panel, not only in the immediate area of the seat panel, but also in the manner of a spring.
- a chair mechanism which meets the usual requirements for seating comfort and the adjustment possibilities is thus created, which does not require a single additional spring. It is also possible to offer relatively simple and inexpensive chairs with a high level of user comfort.
