Definitions

  • the present invention relates to a seat cushion with a rectangular base, which comprises a fluidbe sympathomimetic, elastic hollow body.
  • Seatballs or gymnastic balls which are made of a flexible plastic material and inflated with air. To maintain an upright sitting position, the user is required to actively stabilize his posture on the ball by using the lower trunk muscles. However, since the entire ball must be kept under constant control, such a ball is not particularly well suited for constant use as a seat device, for example in the office, as the seating position becomes slightly unstable. A simple but successful concept is therefore the use of seat pads that can be used with any chair.
  • Various embodiments are known which consist of a flexible material and are filled with air.
  • the object of the invention is therefore to provide a seat pad that allows a dynamic, back-friendly sitting and is easy and versatile, while still restricting the direction and extent of the dynamic movement.
  • a seat pad which comprises a fluid-fillable hollow body made of a flexible plastic material, which has a seat surface, a base surface opposite the seat surface and a circumferential connection region between the seat surface and the base surface, wherein the seat surface and the base surface substantially are rectangular.
  • the rectangular design has the advantage of restricting the movements that the user performs to stabilize his sitting position with the fuselage in substantially the two directions corresponding to the lateral orientations of the rectangular base and side surfaces of the seat cushion, that is to the rear and 90 ° offset to both sides.
  • the seat surface and the base are substantially identical in shape and size.
  • the seat and the support surface are in the unloaded state in essentially parallel to each other.
  • the pelvic tilting of the user is limited in particular to the rear, but also to the front, in order to avoid extreme tilting and thus poor posture.
  • the seat surface and the base surface run in the unloaded state obliquely to each other, so that there is a wedge-shaped cross-section of the seat cushion. This can assist a desired stronger tilt of the pelvis forward.
  • connection area between the seat surface and the base surface is arched outwards.
  • the curvature and the concomitant lack of edges has the advantage that the bearing surfaces of the legs are exposed to the edge of the pad at any point an unpleasant pressure and supports the uniform deformation of the pad and thereby the seat comfort under load.
  • the curvature of the connection region may comprise one or more beads.
  • the seat cushion on flat seat and base surfaces. This allows a stable and well-supported seating position without too deep sinking or too high instability by any bulges.
  • the height of the connection region is significantly less than the length or width of the rectangular seat and base surfaces.
  • the seat cushion is well suited to be used as an inconspicuous seating aid on a chair with ordinary seat height and stable enough for permanent use.
  • the ratio between height and width or height and length of the seat cushion in an embodiment according to the invention is preferably about 1: 3 to about 1: 7, more preferably between about 1: 4 and about 1: 5.
  • the width and the length of the seat cushion are between 25 and 45 cm, and more preferably between 30 and 35 cm. This corresponds to the usual required seat of a user.
  • the maximum height of the seat cushion in the unloaded state is preferably between 4 to 15 cm, and especially preferably between 6 and 9 cm. These heights have the advantage of being able to be used on any standard seating without unduly increasing the seat height while still providing sufficient air cushion height.
  • At least a part of the seat surface of the seat cushion is provided with nubs.
  • the nubs prevent slipping on the seat surface and at the same time ensure gentle circulation of the blood.
  • both the seat surface and the base surface of the seat cushion are provided with nubs so that the cushion can be used on both sides and has additional support on smooth surfaces of the chair.
  • the nubs on the seat cushion have a conical shape with rounded tips, on the one hand to achieve the mentioned desired effect, but on the other hand are not unpleasant when sitting.
  • the nubs are regularly distributed over the seat and / or the base.
  • Seat cushion according to one of the preceding claims, wherein the seat cushion has a valve for fluid filling. This allows the user to choose how much the pad is filled with air or other fluid.
  • the seat cushion is manufactured by means of rotational molding. This method of preparation is well suited for such plastic hollow body.
  • the seat cushion 1 has a flat, in cross-section substantially rectangular or in one embodiment also square shape.
  • the edges and corners are rounded on all sides, so that no disturbing edges occur when sitting.
  • the cushion is already filled with a fluid in the illustrated state, preferably with air.
  • the degree of filling can be chosen freely and influences the seating comfort and dynamics of the cushion via the "hardness" of the seat.
  • a corresponding valve is attached to any suitable location of the seat cushion or incorporated directly into the material of the seat cushion.
  • the seat cushion comprises a base 4, with which the cushion rests on the chair, a seat surface 2 which lies opposite the base surface 4 and is arranged parallel thereto or coplanar thereto, and a connecting region 6 between the seat surface 2 and the base surface 4 shown embodiment, these three areas are integrally formed with each other and go without edges into each other.
  • the seat of the pillow should be approximately flat in the unloaded state; however, a slight curvature inwards or outwards is possible depending on the degree of filling.
  • the connecting region between the seat surface and the base surface is curved continuously and outwards, as can be seen in FIG. 1 or also in the sectional view from FIG. 3. This curvature can be designed as shown, but it can also consist of one or more beads.
  • the elastic surface transmits user's movements to the volume of fluid and the elastic pad itself, similar to a sitting ball.
  • the movement of the surface of the seat cushion according to the invention is that of a round Seat cushion similar.
  • the axes of movement of this movement are predetermined by the basic shape of the pad as illustrated in FIG. While no direction is preferred in the case of the round seat cushion, the angular design ensures that preference is given to movement axes which run from front to back or right to left when the seat is arranged as intended. Possibly unfavorable and harder to stabilize oblique tilting of the pelvis and the lower spine are reduced or completely avoided.
  • the course of the axes of movement parallel to the side edges of the rectangular seat cushion is indicated in Fig. 2 by the two arrows.
  • Another advantage of the invention is that the squared design forces the user into a more central seating position on the cushion.
  • the movements of the pelvic tilting are limited, especially the pelvic movements to the rear, so that a round back position is prevented.
  • the pelvic tilting forward is not extremely pronounced, in contrast to the tilting on, for example, a wedge pillow.
  • the spine of a user is kept in a rather neutral position, which is preferable in untrained muscles or already existing disc damage.
  • Excessive tilting of the pelvis which is not stabilized by the user, could increase the load on the intervertebral discs even further. Therefore, a combination of active and passive stabilization, as achieved by the combination of dynamic sitting on an air cushion while simultaneously guiding the movement through the rectangular shape of the cushion according to the invention, is very advantageous.
  • Such guidance of the movement in restricted directions of movement and preventing excessive tilting is particularly well suited for users to whom the round ball cushion offers too much room for maneuver, as they have, for example, little core muscle strength, as is the case with seniors, back patients at the start of therapy or Generally untrained persons may be the case.
  • the seat cushion can also be a wedge-shaped one Have cross-section, so that seat 2 and base 4 are inclined to each other, as shown by the sectional view in Figure 3b.
  • the rectangular basic shape of the seat cushion and the curvature of the connection area can be retained.
  • the seat cushion helps to dampen movement and impact on the spine via the air cushion. Any movement that is carried out by the user on the pillow is never abruptly stopped, but gently continued. As a result, the intervertebral discs are spared and relieved.
  • the air supply automatically provides an even pressure distribution, so that no unfavorable pressure points occur, which for example has a positive effect on the veins running in the sitting area and the thighs.
  • knobs 8 are arranged on the surface of the pad which serves as the seat 2 . These serve on the one hand to promote blood circulation and on the other hand prevent slipping or slipping on the pillow.
  • the knobs 8 are formed in the preferred embodiment shown in a conical shape with rounded tips, but may also be in any other form.
  • the nubs are formed integrally with the surface of the pad, which is easy to achieve in the conical shape shown.
  • the nubs could also be formed in a further embodiment also on both surfaces of the seat cushion, so that the user can use the seat cushion on both sides;
  • the nubs or generally the surface structure on each side of the seat cushion could differ in shape and / or size, so that the user can choose at any time between two surface finishes.
