DE102006053053B3 - Dynamic seat contact support for e.g. chair, has seat plate connected with elastic unit over ball bearing in tiltable and rotatable manner in each direction in base of elastic unit, where base of elastic unit is connected with baseplate - Google Patents

Abstract

The support has a seat plate (1) connected with an elastic unit (3) over a ball bearing (5) in a tiltable and rotatable manner in each direction in a base of the elastic unit. The base of the elastic unit is connected with a baseplate (2), and a delimitation ring is attached to the base plate, where center of the ring is identical with a center of the elastic unit. The ring is attached under the seat plate, where maximum tilting angle of the seat plate is determined by radius and height of the ring. The plate and/or the elastic unit are made of plastic.

Description

The The invention relates to a dynamic seat support for tilting and rotational movements.

The modern seating school recommends as dynamic as possible Sitting, sitting with movement, muscle tension, bad posture and disc damage to prevent too one-sided continuous loads.

By the well-known dynamic seating elements becomes a dynamic sitting already possible. However, the impulse to move must always come from the sitter himself. In order to initiate the movement, a certain resistance must be overcome become, so that after a certain time a lack of exercise established.

Out The prior art dynamic seating elements are known which already movement possibilities, as tilting movements and rotational movements offer.

From the DE 1 805 116 A is a chair known, the seat support is pivotally mounted by means of a helical or torsion spring along the axis of symmetry of the chair, wherein the helical or torsion spring is mounted on a pedestal via a hinge, which may have, for example, balls.

There the hinge in this seating is mounted below the tilting mechanism, the axis of rotation remains always perpendicular to the ground and does not adapt to the tilting movement the spine. As a result, it comes to sweeping movements, which also upper body and Head to be moved laterally.

outgoing From this prior art, the invention is based on the object to create a seat cushion, the tilting and rotating movements allows such that the axis of rotation always remains perpendicular to the tiltable seat.

These The object is solved by the features of the main claim.

advantageous Embodiments are specified in the subclaims 2 to 7.

Thereby, that is a ball bearing between seat and elastic element is, the axis of rotation remains unchanged even with tilting movements to the plane of the seat plate.

The Base of the elastic element can be connected to a base plate be as easy to use as a unit both on unpadded as Can also be used on upholstered seats.

Around to limit the inclination between seat and base plate and thereby the pinching of e.g. Avoid fingers under the edge of the seat can a limiting ring or limiting elements may be provided.

The Material of the seat plate may consist of a group consisting of wood, Plastic, fiberglass and metal, to be selected. Is the seat plate upholstered, the upholstery material can consist of a group consisting made of foam without cover, foam with fabric or leather cover, Foam with molded plastic cover, cork, artificial turf and felt, selected be.

Around Slipping the seat cushion on a chair or damaging the seat Storage area too can prevent on the underside of the base plate a protective layer to be appropriate.

By the seat cushion according to the invention should preferably many degrees of freedom, directions of movement with the least possible resistance allows become. As a result, the sitter is in an unstable balance and stays by constant, automatic, small compensatory movements to maintain balance moving. The continuous back movements cause muscle tension and disc damage prevented. The small compensatory movements are from the subconscious controlled and the sitter does not have to constantly be aware of the impulse to move give. As a result, a lack of movement is avoided.

By the dynamic seat pad gets the sitter more possibility of movement with tilting and turning movements, which enhances well-being and creativity to be influenced.

The Invention will now be described with reference to an embodiment with reference explained on the drawing.

It demonstrate:

1 : a schematic representation of a seat cushion according to the invention

2 : A plan view of the seat pad according to 1 , schematized

3 u. 4 : the seat cushion according to 1 and 2 with a delimiting ring

The in the 1 to 4 seat cushion shown has a base plate 2 on, on the with tig an elastic element 3 , eg a rubber cylinder, is fastened. The attachment can eg by a screw 4 or by gluing. On this elastic element 3 becomes a seat plate 1 with an axial ball bearing 5 so attached that the ball bearing 5 between seat plate 1 and elastic element 3 located and the seat plate 1 in relation to the elastic element 3 and base plate 2 can be rotated. This connection can eg with a screw 4 respectively. The connection between seat plate 1 and ball bearings 5 and / or ball bearings 5 and elastic element 3 can also be done by gluing, for example. The elastic element 3 can also consist of another elastic material, such as plastic or metal.

The base plate 2 can be placed on the seat of a normal chair or seat.

As the 3 and 4 show, the tilting of the seat plate 1 through a ring on the base plate 2 , called bounding ring 6 , to be delimited end-to-end, being the center of the boundary ring 6 identical to the center of the elastic element 3 is. About the distance of the ring 6 to the elastic element 3 and about the height of the ring 6 the maximum tilt can be determined. As a result, excessive tilt angle and the pinching of eg fingers under the edge of the seat plate can be avoided. The ring 6 can be made of different materials, such as wood, rubber, plastic, felt.

The limiting mechanism does not have to be ring-shaped but can also consist of one or more on the base plate 2 attached limiting elements exist, by their height and distance to the center of the elastic element 3 the maximum tilt angle can be determined. Heights and distances to the center of the individual boundary elements need not be the same, so that the maximum tilt angle can be set different for different directions. The material of the limiting elements may for example consist of wood, metal, plastic, felt, rubber.

The seat plate 1 can be upholstered. For upholstery foam with or without cover, cork, felt or cut synthetic turf can be used as a design element.

The underside of the base plate 2 can be upholstered to prevent it from slipping on the chair or damaging the shelf. The bottom may also be covered with a deformable layer, eg foam, to accommodate the ergonomically shaped seat of some office furniture.

The outer shape of the seat plate 1 and / or base plate 2 is arbitrary and can be shaped eg round, oval or ergonomic.
