Definitions

  • the invention relates to a piece of seating furniture with a frame, a seat surface and a backrest, the seat surface being displaceable forwards or backwards relative to the frame and with it the backrest which is articulated and pivoted on the frame and on the front side of which a front backplate rests. which is movable relative to the backrest.
  • the invention avoids these disadvantages. It is based on the object of designing seating of the type mentioned at the outset in such a way that the lumbar region is always supported regardless of the inclination of the backrest of the seating furniture selected by the user, the user being able to make any inclination of the backrest while simultaneously displacing the seating surface, without a relative shift between him or his clothes and the individual parts of the seat and the front back plate.
  • the invention is characterized in that the front back plate is divided in its central region by an essentially horizontally extending joint into an upper and a lower partial plate.
  • the backrest is thus pivoted together with the seat surface and, at the same time, the front backplate slidably mounted on it is displaced relative to the backrest, so that the aforementioned disadvantageous forces no longer occur.
  • a growing area in the area of the joint between the seat surface and the backrest is filled by the front back plate, so that the London vertebra area of the person in question is supported very well and constantly over the entire displacement path.
  • the front back plate extends at least to the height of the backrest, which is therefore completely covered towards the user.
  • the front back plate can also extend upwards beyond the backrest.
  • the front back plate also moves forward and backward together with the seat. It serves to noticeably improve leadership the front back plate below its joint when a web connects the joint joint between the seat and the backrest on the one hand to the front back plate on the other. The web moves to a certain extent automatically when the seat and front back plate are shifted, the portion of the front back plate located below the joint relative to the frame in the desired manner.
  • the forces to be applied here are particularly low if the joint between the web and the front back plate is arranged at a distance from the lower edge of the front back plate, as is preferred.
  • the conditions are preferably such that the web forms an approximately right angle with the front back plate in the rest position of the seating.
  • a spring element connects the frame to the seat surface that pulls the seat surface into the rest position.
  • a pressure element can also be provided, which presses the seat surface into the rest position or into the starting position.
  • the novel seating furniture has a headrest, its inclination is also adjusted, the backrest and the front backplate being articulated in the neck area for this purpose and a band connecting the seat surface to the uppermost part of the backrest.
  • the band is preferably designed as a steel band.
  • a chair with armrests without armrests is shown in the drawing.
  • the principles described can equally well be applied to a chair or other seating, for example an aircraft seat, motor vehicle seat, armchair, etc., with or without armrests.
  • the novel seating furniture consists of a frame 1, a seat 2, a backrest 3 and a front back plate 4 located on the front of the backrest.
  • a guide rail X runs essentially horizontally and guides the seat surface 2 on the frame 1.
  • Another guide rail Y guides the rear area of the seat 2 and the front back plate 4.
  • a further guide line Z runs in the area of a joint C of the front back plate 4 and guides it on the backrest 3.
  • a tension spring 5 connects the frame with a joint A, which connects the lower part of the backrest 3 with the rear part of the seat 2.
  • a web 6 also acts, the other end of which is attached to a joint D on the lower part of the front back plate 4. In the starting position (cf. FIG. 1), the web 6 forms approximately a right angle with the lower part of the front back plate.
  • the front back plate thus consists of several parts, namely a lower part 7, which is formed between a joint E and the joint C.
  • the hinge E is formed on the lower edge of the front back plate and is guided along the guide Y.
  • the front back plate consists of a central part 8 and one or more upper parts 9, which are connected to one another via one or more joints G.
  • the upper part 9 is provided when the seating has a headrest.
  • the rear backrest 3 is continued in an upper part 13, which is articulated on the rear backrest 3 via a joint F.
  • Padding 10 for the seat surface and 11 for the backrest with Gann plate are also indicated in the figures. If the seat surface 2 with its cushion 10 is pulled forward in the direction of the arrow 12 by the body movement of a person sitting on the seating furniture, the joint A of FIG. 1 moves to the location A1 of FIG. 2. The spring 5 is expanded. As a result, the rear backrest 3 rotates about the joint B with which it is articulated on the frame 1. The angle alpha between the seat 2 and the backrest 3 increases. With constant distances between the joints A - D and D - E If this angle alpha is increased, the joint E must move to E1 (FIG. 2). This inevitably moves the joints C to C1 and D to D1. This creates a continuous support of the lumbar region by means of the lower part 7, which is tracked.
  • the movement described back and forth can only be achieved by a corresponding body movement, and that without actuating levers or buttons.
  • armrests are not included in the construction described because the backrest 3 is pivotably mounted on the frame 1 via the joint B. Rather, the armrests only need to be connected to the frame 1 in the usual way.
  • the spring balancer 5 holds the seating furniture in the upright position in the unoccupied state.
