Abstract
A seat furnished with seat part (3) and a back rest (4), where with seat part (3) and back rest (4) can be moved in regard to each other. Seat part (3) and back rest (4) are connected to each other and to separate from each so that the motion of the seat part (3) directed either to forward and/or down or backward and /or down can be transmitted either to an up forward and/or backward directed motion of the back rest.
Description
CHAIR
The invention relates to a chair furnished with a seat part and a back rest or similar, in which the seat part and the back rest are movable in regard to each other. With the chair all kinds of bases are meant, which are intended for sitting and resting, for instance couches and multifunction beds.
In seats adjustable seat parts and back rests are known. Usually the seat parts are individually adjustable as well as the back rests. Known as regulation of the seat part is height regulation and tilting, and tilting of the back rest, and also known is tilting of the whole seat position. By these application methods the aim is only to find the right position, and the regulations are locked within the limits wanted. In known seats there is in no way any relief for the back of the sitter.
By means of a seat according to the invention, in this regard a notable improvement is achieved and the invention is characterized in that the seat part and back rest are connected to each other and to separate from each other so that the motion of the seat part directed either to forward and/or down or backward and/or down can be transmitted either to an up forward and/or backward directed motion of the back rest.
The advantage of the seat according to the invention is that by means of a mechanism transmitting motion to the back rest or by means of other tools the back rest relieves the pressure of the sitter's vertebra and the feeling of pressure. Thus the back rest partly holds up the sitter. The invention is simple and cheap to accomplish in its basic form, where the sitter's own weight moves the seat part and this motion is transmitted as a motion raising the back rest. Also other embodiments of the invention that need outside energy are easily accomplished electrically, hydraulically or by means of pneumatic.
In the following the invention is disclosed with reference to the enclosed drawing, where Figure 1 shows an embodiment of the invention from the side.
Figure 2 shows the seat of figure 1 with the parts of the seat part and of the back rest moved.
Figure 1 shows a seat comprising the seat frame 1, including legs, and also a permanently fixed back rest frame 2. Further the frame 1 has on the seat under-side as a firm part an arm 10 furnished with an articulated point. All the other seat parts are movable.
Seat part 3 rests on a separate auxiliary frame 6, 7 and the frame 6, 7 is arranged to glide on frame 1, for instance, forward on conductors (not shown), and at the same time diagonally downward. Back rest 4 is arranged to move diagonally upward on auxiliary frame 5 from the position of figure 1. For instance, there is in the upper end of auxiliary frame 5 inside frame 2 a moving roll 12, by means of which the upper end of the back rest can move in the direction of frame 2.
The motions of seat part 3 and back rest 4 are by means of lever mechanism 8-11 connected to each other so that when the seat part and its auxiliary frame 5 are moving forward because of the sitter, and at the same time diagonally downward, bracket 9, which is fixed to auxiliary frame 7, meets lever 8, which is articulated to the end of fixed arm 10, whereby lever 8 turns and its other end lifts arm 11 so that on rising also auxiliary frame 5 of the back rests gets up.
When also the back rest 4 is furnished with portion 14, the back rest tends while rising also to raise the sitter. The leverages to lever shaft 8 are so chosen that remarkable raising force is produced into the back rest 4.
Figure 2 shows the same seat now with seat part and back rest moved. If the sitter would sit in place, his/her back would be affected by raising force from the back rest. If the back rest of auxiliary frame 5 would rise and sink in its own direction, as shown in figure 2, a slit will be formed between seat part 3 and back rest 4. Formation of this slit can also be avoided arranging in the lower end of the auxiliary frame 5 a steering, for instance a sleeve in the seat back part, whereby the auxiliary frame 5 can rise and sink in the sleeve and move together with seat part 5.
The sitter's own weight can be easily transmitted as force raising the back rest, if seat part 3 is arranged to move by means of its the auxiliary frame 7 also downward, while moving forward. A proper angle for the direction of the seat 3 motion is, for instance
between 5-25°. In certain cases the sea 3 motion backward and at the same time downward can com into question. The rise of back rest can be activated in many ways by using outside energy, as electric, hydraulic, or pneumatic equipment. Advantageous for the invention is hat the return motion of the seat also returns the back rest, or vice versa, the return of the back rest down also returns the seat to its original position. This can be accomplished by simple mechanism, as by means of a pulling element.
Claims
1. A seat furnished with seat part (3) and a back rest (4), where seat part (3) and back rest (4) can be moved in regard to each other, characterized in that the seat part (3) and back rest (4) are connected to each other and to separate from each so that the motion of seat part (3) directed either to forward and/or down or backward and/or down can be transmitted either to an up forward and/or backward directed motion of the back rest (4).
2. A seat according to claim 1 characterized in that back rest (4) can be moved by means of force generated to seat part (3) by the sitter.
3. A seat according to claim 1 characterized in that the mobility of back rest (4) is activated by means of an outside power unit, as an e electric lifter.
4. A seat according to claim 1 characterized in that that back rest (4) comprises shapes (14), which raise the sitter in the sitter's back portion, when to back rest (4) a motion upward is directed by means of the upward motion of seat part (3).
5. A seat according to claim 1 characterized in that the tools transmitting motion between seat part (3) and back rest (4) are mechanical (8-11), electric, hydraulic, pneumatic tools, as chains, cables or such.
6. A seat according to claim 1 characterized in that the lower end of back rest (4) is by means of portion (13) in its lower end connected to move with the back part of seat part (3) during its motions directed forward^ackward, at the same time when said portion (13) moves up or down in order to avoid formation of slit (a) between seat part (3) and back rest (4).
7. A seat according to claim 1 characterized in that seat part (3) is arranged to move diagonally downward at an angle between 5 - 25° in order to move the back rest (4) at least partly upward by means of said motion
