NO852035L - WHEELCHAIR WITH SEATLETS AND CUTTING OPTIONS. - Google Patents

Description

DESIGNATION

Recliner with seat joints. and trim options'

area of application

The chair can be used for sitting and lying positions

different positions,

STATE OF THE ART

How the principles of sitting/lying combinations are created

day, the backrest is hinged to the seat by connecting these together at the lower part of the backrest and the rear part of the seat cushion. This leads to a wrong movement in relation to the body/chair, and is an orthopedic problem.

THAT WHICH IS PARTICULARLY ACHIEVED

With this invention, the friction that occurs between the back cushion and the sitting person's back when the latter moves to different sitting/lying positions will be eliminated. This is the orthopedic problem according to medical doctors.

THE MEANS NECESSARY FOR THE SPECIAL' TO BE ACHIEVED

By placing the hinges (joint) in the seat cushion in a position between the knee benders and the buttocks, you will achieve constant support around the spine and pelvis by placing the hinges in a more robust anatomically correct area, here the hip joint. That is that the invention retains part of the seat cushion for the back cushion, as this is molded in one piece;

the seat here has the shape of an old-style wooden seat. The rest of the seat cushion forms the support for the thigh (knee flexors). An electric frame cover has also been fitted which is attached to a support rod (axle) which runs from hinge to hinge. This will mean that, when seeking a reclining position, the frame cover is tightened around the seat cushions, thereby reducing the seat pit. For the cushion for the fully molded back/seat. air pockets can also be inserted into the cushion part with interconnected channels that provide support around the buttocks and up to the area around the lower thoracic vertebrae, this to further adapt to different body types. To achieve the movement to the various positions, the chair seat is suspended in a circular shape

strap that makes up the back of the chair and part of the seat follows the various positions. The hinge that sits here between the seat cushion is seat-seeking and controls the seat cushion's outer joint with the help of the knee benders dB this is possible via the feet's constant floor contact* The chair has a handle that can be set in a position such that Bt but can push his own body weight back and forth over the sliding track on the frame , The leg pillow is designed so that the roller at the end leads the pillow to a right angle i

relation to the seat cushion joint when the "bnhem position" is adopted.

FIG ORIGINATION

Reclining chair with bow strap according to the invention is shown in the drawing, where Figure 1 shows the profile of the chair. Figure 2 shows the armrest with the slides and locking mechanism as well as handles for trim movements.

DETAILED EXPLANATION OF WHAT YOU SEE IN THE DRAWING

Figure 1 shows a chair suspended on a circular-curved frame with circular-curved suspension (0) which forms part of the armrest (S). The armrest (S) follows the path of the chair frame (T) when changing positions. The armrest (S) is fitted with a release mechanism for a clamp lock which makes it possible to lock the position, figure 2t to the slides, fig. 1 (T). Handle (I) for trim movement mounted to strap. (A) shows the normBl sitting position with the possibility of a "bohemian position" (A2). (B) shows the lying position where (E1) illustrates the sitting-lying position and (B2) the lying position. The circular frame system can also be solved (fig. 2) by parallel bars to the outer seat cushion from the frame. The path of the chair (T) will then have an ellipse-shaped path so that in a reclining position the entire chair seat (also with back) is moved backwards, so that the parallel bars are inclined. Hinge (L) is centered so that it can receive control from the knee benders. Hinge (L) follows a circular slide leg during position changes from position (A) to . (B). Part bv hinge that follows the slide spDret has stop grooves for the movements (A2) and (B2), alternative 2 is dashed.

Figures 3 and 4 show the chair seat from above.

Claims (1)

Recliner w/seat joint where the hinge joints for the lying position are characterized by the joint (L) being moved to a position between the buttocks and the knee benders, or just below the hip joint, The frame is characterized by its round sliding track (T) which makes it possible to change position, A-B, as the armrests characterized by their round suspension slide (0) slide to desired positions (A* -B). The outer seat cushion (A1, A2, B1, B2) forms the second part of the seat cushion with a connection to the back part with a hinge (L) which is centered. The possibility of trim, characterized by handles that make it possible to push the body weight forwards and backwards, where you regulate the resistance in the armrests (S).. Handles attached to the frame in fig.- 2 (R), the seat cushions on ■ ff.• 1 • (K-Y), the pelvis with femoral bench (H). Fig. 3 and U show the seat cushions (K-Y) characterized by the handle separation (L) in the middle of the seat. The seat cushion (K) is shaped like an old-style tractor seat, and (Y) forms the outermost (second) part of the seat. The air pockets (M) characterized by their locations in the seat (K) and up in the lower part of the chair back. Fig. 1 (H) shows the pelvis and part of the femur in a sitting position. The chair can also be suspended at a point with the inertial path in a different position so that the same possibility is achieved using the hinge (L). This will then cause another rotational movement.
