Definitions
- the invention relates to a chair according to the preamble of the first claim.
- GB-A-553,750 discloses a chair which has a backrest and a curved, S-shaped seat when viewed from the side.
- the user's isch rest in the lowest point of the seat and the thighs are forced into a horizontal, possibly even angled position by the highest point of the seat, so that an ergonomically unfavorable position results.
- GB-A-1,294,092 describes a generic chair with a reclining backrest and a seat, divided into a rear, front rising and a front, falling region. Again, the user is placed in an ergonomically unfavorable position in which the thighs are horizontal or even angled and the upper body is leaning back.
- the task is therefore to provide an ergonomic chair that does not have these disadvantages.
- someone sitting on the chair should adopt a posture that is easy on the back without tiring the user.
- the thighs come to rest on the front area of the seat that slopes forward. Similar to the seat wedge, this results in a slightly sloping position of the thighs, which makes it easier to straighten the upper body.
- the ischium (os tuber ischii) rests on the rear, rising area of the seat and provides a good grip.
- the backrest supports the back in the area of the thoracic vertebrae and pushes it forward, which enables relaxed, upright sitting.
- the backrest is preferably shaped in such a way that the buttocks are not hindered from behind and are at most supported laterally.
- the seat, and in particular its front area, can also become narrower towards the front. This causes the thighs to assume a slightly spread, V-shaped position. This makes it even easier to tilt the pelvis forward.
- FIGS. 1 to 3 The basic structure of the exemplary embodiment described can be seen from FIGS. 1 to 3.
- the chair has a forward converging seat 1 and an upward converging backrest 2 and rests on three legs 3, 4, 5.
- the seat is in a front and a rear area 6 and 6 respectively. 7 divided. In this exemplary embodiment, both areas are executed in a flat manner.
- the front area drops forward, the rear area rises forward.
- the backrest 2 is recessed in a lower buttock area 8.
- the upper support part 11 is located above the rear area 7 of the seat surface.
- the opening 12 serves to grasp the chair.
- the chair shown here is made of wood and upholstered in the surface 1.
- Typical dimensions of the example shown are: total height a of the backrest from the seat approx. 45 cm; Length b of the rear area of the seat surface about 15 to 25 cm (preferably 18-20 cm); Length c of the front area of the seat to the apex about 15 to 25 cm (preferably 20 to 22 cm); Width d of the recessed buttocks area approx. 15-25 cm (preferably 20 cm); Height e of the buttocks area approx. 15 - 25 cm (preferably 20 cm); Rise angle of the rear area of the seat approximately 4 ° to 10 ° (preferably 6 °); Decline angle of the front area of the seat surface about 4 ° to 10 ° (preferably 6 °). These dimensions relate to the design model shown and can also be selected differently.
- FIG. 4 shows the chair according to the invention with a person sitting on it.
- the thighs 20 are in a slightly sloping position and are somewhat spread apart due to the seat surface which becomes narrower towards the front.
- the seat leg 21 of the seated person rests on the rear area 7 of the seat surface.
- the rear seat part and the sacrum 22 can follow their natural, curved course and are not hindered, but only supported laterally by the support parts 9 and 10.
- the upper body is supported in the area 23 of the burst vertebrae and in particular the sixth thoracic vertebra by the upper support part 11 of the backrest. Thanks to the shape of the backrest, which becomes narrower at the top, the shoulder blades are exposed, so that a complete erection of the shoulder area is not hindered.
- the seated person automatically assumes a relief posture in which the pelvis is tilted forward, the chest is straightened and the spine is optimally loaded. Seat damage and in particular Damage to the spine and intervertebral discs is prevented.
- the chair Since the chair has only one front leg, the lower legs are not hindered and can also be angled backwards.
- the chair is not only suitable for healthy, but also for sick people.
- patients with traumatic brain injury who take a forward bent position in a normal chair straighten up in the chair described.
- the chair is also very pleasant for people with hip problems, since the spread leg position makes it easier to sit down and get up.
- the design of the chair shown in the figures can be modified in many ways.
- a conventional telescopic leg can be used, as is known from office chairs. This allows the height of the seat to be adjusted to the length of the legs of the seated person.
- the two areas 6 and 7 of the seat surface form two flat levels here. But you can also bend and e.g. be convex.
- the front area 6 can also drop on both sides so as not to impede the thighs and to facilitate a spread-out sitting position.
- the recess 8 of the backrest can be omitted in particular if the backrest in the seat area is set back sufficiently.
