Definitions
- the invention relates to a Clothingrichtrollstuhl with a chassis and a hinged on the chassis raising rack, a first and a second
- Parallelogram lever whose front ends are hinged to the chassis and pivotable about a first and a second pivot point and at the rear ends of the backrest is articulated at a third and a fourth hinge point.
- European patent EP 0 815 822 discloses a righting wheelchair having a
- Chassis and a Aufrichtgestell comprising a seat and a backrest.
- the erecting frame comprises two parallelogram levers, the front ends of which are articulated to the chassis and pivotable about fixed pivots. At the rear ends of the ParaUelograrrvmhebel the backrest is hinged.
- the Anlenkun the Aufrichtgestells by means of two parallelogram lever has the advantage that the
- Backrest does not change the inclination angle when erecting the erecting rack, i. the angle of inclination which the backrest occupies relative to the horizontal in the sitting position is also present in the erecting position.
- a disadvantage of the Aufrichtrollstuhls described is that the backrest is not adjustable in inclination.
- An adjustability of the backrest is desirable because the wheelchair users want to adjust the inclination of the backrest depending on the operation.
- the backrest is tilted slightly forward so that it occupies an acute angle with the horizontal.
- the wheelchair user wants to sit relaxed in the wheelchair and will tilt the backrest backwards accordingly (obtuse angle).
- the erecting wheelchair according to EP 0 815 822 has a frame formed from tubes on which the front and rear wheels are arranged.
- the leg of a legrest is translationally guided in the frame, which makes the footrest a stable
- the Aufrichtgestell is pivotally connected via a connecting member with the shaft of the legrest such that when erecting the Au frichtges partly the footrest moves down.
- a disadvantage of this construction is that the footrest is arranged so far in front of the seat, that the assumption of a dynamic sitting position is prevented by the wheelchair user.
- wheelchair users who do sports want to take an active driving position to increase the maneuverability of the wheelchair.
- Such is characterized in that the
- a trolley trolley which has a consisting of two longer and two shorter levers articulated parallelogram.
- the longer levers are adjustable in length.
- the shorter and longer levers are connected to joints, which joints allow only a Rota tionbe wegun g the lever relative to each other.
- the axis of rotation of the seat occupies a different position on the frame than the axis of rotation of the articulated parallelogram.
- the back adjustment has a self-contained articulated parallelogram and the seat moves independently of this.
- One of the levers is a length-adjustable gas spring, which allows the wheelchair to be set up.
- the seat and the gas spring are hinged at their front ends to the support frame of the wheelchair and hinged with their rear ends to a plate.
- the rear E de the seat is L-shaped, whereby the rear end of the seat in the region of the plate is offset in the erected position in the form of a step to the rear.
- the seat is therefore with the backrest in the erected position in any plane.
- the plate forms an unpleasant for the wheelchair user projection, which prevents the wheelchair user leaning against.
- Erecting position substantially in the same plane as the seat is. Also, the wheelchair as many settings allow, so that the same chair for different body sizes is customizable.
- the invention relates to a Clothingrichtrollstuhl with a chassis and a hinged on the chassis raising rack.
- the Aufrichtgestell has as essential components on a first and a second Parallelogrammhebel, hereinafter referred to as perch and control rod.
- Their front ends are hinged to the chassis and pivotable about a first and a second pivot point.

- one of the articulation points is adjustable relative to the other articulation points. It is particularly preferred if one of the hinge points a
- the perch and the control rod have a different length.
- optimization of geometry can be achieved.
- the parallelism of the backrest and seat in the erect position can be optimized regardless of the inclination of the backrest in the sitting position.
- one of the bars is shorter than the perch, by a certain amount, preferably between 1 and 30 mm and more preferably between 15 and 25 mm. It has been found that relative length differences between 1 and 6% and preferably 2 and 4% are sufficient to achieve the desired functionality of the bars, preferably the control bar, is shorter than the perch, by a certain amount, preferably between 1 and 30 mm and more preferably between 15 and 25 mm. It has been found that relative length differences between 1 and 6% and preferably 2 and 4% are sufficient to achieve the desired functionality of the
- a displacement of a hinge point can be achieved in various ways.
- One possibility is to make the adjusting rod and / or the seat rod variable in length. This can, for example, with a threaded sleeve with two
- Hinge point is variable relative to the other hinge points in stages.
- the adjusting mechanism can be realized for example by a slot and a locking element.
- the locking element can be, for example, a set screw or a clamping screw, which can be tightened in any position along the slot.
- the first part median ismu s can therefore be infinitely variable.
- the slot is provided on a connecting piece which connects the third and fourth hinge point.
- Connector which acts as one of the levers of the lever parallelogram, may be formed such that the seat post, the control rod and the backrest column are hinged thereto and lie the seat post and the backrest column in the erected position in a plane.
- the pivoting mechanism is formed by a base plate and a pivot arm having a first and second end, wherein the pivot arm is pivotally connected at its first end pivotally about a fifth hinge point to the base plate.
- Backrest are pivotally connected to the base plate and the control rod with the fourth pivot point is articulated mi d m the second end of the pivot arm connected.
- the swivel arm can be easily pivoted relative to the base plate, whereby the backrest inclination is very precisely adjustable.
- the end positions of the pivot arm are predetermined relative to the base plate by an eccentric.
- the eccentric can for example be realized by a turntable which rotates in the base plate and a bolt which is eccentrically fixed to the hub. The bolt is rotatably received in a passage of the swing arm.
- the eccentric allows the backrest tilt is very accurate and almost infinitely adjustable.
- the eccentric is durable and does not wear off.
- the position of the fourth pivot point is variable by means of the adjustment mechanism, because to adjust the adjustability of one of the rear
- the two first (front) hinge points are fixed points.
- the hinge points of the seat and the control rod in the longitudinal direction of the parallelogram are seen as offset by a certain distance from each other on the chassis, i. they do not lie vertically above each other, but are offset from one another.
- the chassis comprises two side parts, which are connected to one another via a strut. This results in a stable construction.
