Description

GERMAN

There are combined reclining and sitting beds known from movable adjustable parts in which at consisting of three hinged support surfaces (foot, seat and back), The seat part can be lowered on one side and is therefore inevitable on a construction arranged on a base the back part can be raised on one side. All of these constructions have the disadvantage that only in one Position of the system of contact surfaces loaded with the human body equilibrium prevails and that at least one of the interconnected support surfaces must be moved horizontally, which of course still involves considerable friction.

The subject of the invention is a combined reclining and sitting bed that can be reclined as desired allows the user many intermediate positions and an anatomically most favorable sitting position, all of which Transfer movements independently by rolling. The change of position happens naturally human movements without any vertical displacement forces when moving from one position to the other or overcome large frictional forces and loosen and screw connections without any having to find out again. If the user stretches out in the sitting position, the support surfaces take over without any operating handles, the lying position automatically locks into place and locks into place here by itself. Conversely, if the user wants to sit up, they move at the slightest after they have been disengaged Contraction of the abdominal muscles counteract the contact surfaces of the sitting position.

In the drawing, an embodiment of the invention is shown schematically, namely shows

Fig. 1 the bed in the lying position and Fig. 2 the bed in the outermost sitting position.

The support surface of the bed made of belts or springs is hinged to each other in three connected parts divided, namely a foot part 3, a seat part 2 and a back part 1. The length ratios the support surfaces 1, 2, 3 are adapted to the body dimensions. The foot part 3 is firmly on Underframe 5 arranged.

In order to get from the couch to the sitting position, the relatively heavy back section must 1 in be brought up a steep slope. In addition, one must correspond to the bending of the user's knees Adjust the angle between the foot part 3 and the seat part 2.

For this purpose, the seat part 2 pivots with its rear end into a relatively lower center of gravity, wherein the back part 1 rises with its rear end. When the contact surfaces 1, 2 are flattened again the main pressure from the seat part 2 on the shoulders Combined reclining and sitting bed

and thus shifted to the back part 1. The large lever arm of the back part 1 leaves when it is pushed back raise the inclined seat 2 back to the horizontal position. The arranged on the underframe 5 Templates 4, on which rolls 6 attached to the back part 1 roll, are curved so that in the implementation of the adjustment of the back part 1, its erection from the lying position to the sitting position is facilitated and the recovery of the lying position is difficult. The counter pressure when pushing back of the back part 1 through the upper body will generally be perceived as pleasant. Since the Body proportions of people are different, the templates 4 can also be adjustable or also be built to adjust automatically during the change of position. The shape of the Template 4 is thus the sequence of the change in position of the support parts 1, 2 influenced. Consequently Any desired intermediate positions with a stable center of gravity can also be achieved. One can also store the templates 4 on an axis in such a way that they are positioned on the underside of the during the adjustment process Unroll back part 1, whereby mutual teeth or corrugations prevent sliding. The templates 4 can be arranged on the underframe 5 and the rollers 6 on the back part 1 or vice versa be. Latchings for the end and intermediate positions of the support surfaces 1, 2 can also be provided be.

The bed is suitable as a bed with reading position as well as an adjustable couch, deck chair, Sickbed or the like

Claims (7)

Patent claims: 1. Combined reclining and sitting bed, made up of three on an underframe, with hinges interconnected support surfaces 009 677/125 (Foot, seat, back part), the seat part of which can be lowered on one side and therefore inevitably the The back part can be raised on one side, characterized in that the back part (1) is fixed to the underframe (5) arranged foot part (3) rolls on curved templates (4) by means of rollers (6). 2. Bed according to claim 1, characterized in that the curvature of the templates (4) is formed is that raising the back section (1) from the lying position to the sitting position is made easier and the recovery of the lying position is difficult. 3. Bed according to claim 1, characterized in that the curvature of the templates (4) is designed so that both desired end positions with stable center of gravity and intermediate positions of the Support surfaces (1, 2) are possible. 4. Bed according to claims 1 to 3, characterized in that the templates (4) on the underframe (5) and the rollers (6) are arranged on the back part (1). 5. Bed according to claims 1 to 3, characterized in that the templates (4) on the back part (1) and the rollers (6) are arranged on the underframe (5). 6. Bed according to claims 1 to 5, characterized in that the templates (4) in such a way an axis are mounted that they roll on the underside of the backrest (1), with mutual Serrations or corrugations prevent sliding. 7.
