"Seat, especially for motor vehicles" Marguerite, Agnes DAVIS, née BEÜRRIER Priority: FRANCE, 6 June 1966

The object of the present invention is a seat of a new and simple type with improved comfort, in particular for means of passenger transport, such as passenger cars, motor boats, airplanes, etc ...

The seat according to the invention is particularly suitable for bumps, jerks and sudden movements caused by the vehicle the passengers are transferred, picked up, distributed and attenuated.

The seat has a rigid, one-piece support structure, e.g. a tubular support structure for the seat board and the backrest Frame forms.

009834/0491

The seat according to the invention is particularly remarkable in that that in the frame a made of flexible and essential * · Inextensible elements formed latticework or mesh is built, which at the same time the seat board and the backrest carries and which at least through two substantially opposite edges on the above-mentioned frame Is attached with the help of elastic means such as coil springs.

The spiral springs carrying the braid allow to a certain extent that which is transmitted from the vehicle to the occupants To absorb shocks elastically., The flexible, but essential The non-stretchable braid acts like a hammock and lies over a wide area on the body of the occupant being carried at. Since it is essentially inextensible, the braid resists to a certain extent the uncomfortable, rocking resonance frequencies, which can occur with elastic braids.

According to a further feature of the invention, the braid of crossed steel wires or similar · At least some of the wires are covered with a flexible or fibrous material, such as _e string, Papierbindfaden, natural or synthetic fibers or wrapped "

In order to improve the comfort of the occupant, the seat frame can have a certain curvature, which namely gives the backrest a curvature. It is also possible to provide superstructures that work closely with the frame to give the seat the desired curvature; in this case the mesh is stretched over these superstructures. In addition, a suitable covering of the seat is provided. _Ä .

The invention is illustrated below by the detailed description an embodiment and with reference to the attached drawings explained in more detail by way of example.

- Figure 1 let a perspective view of the invention manufactured seat supports;

- Figure 2 shows in a larger hatred stick and with partial Tear out a part of the braid that is shown in FIG Sits is built in |

- Figure 3 is a light in cross section of the line III-III along the figure 2!

- Figures 4 and 5 show a spring on a larger scale, used for fastening the braid in the support frame will·

According to the embodiment shown in the drawings the seat of the invention consists essentially of a e.g. tubular frame 1 in which the flexible, but essentially non-stretchable braid, which at the same time supports the 3xtzbrett and the backrest, is built in · The frame 1 has a Rigidity sufficient to carry the occupant with practically no change in shape

Bas braid 2 consists of essentially inextensible Wires, e.g. steel wires similar to piano strings. According to the example shown, the wires are in two substantially perpendicular directions crossed. The wires 3 are parallel to the side 4 of the frame, while the wires 5 run parallel to sides 6 of the frame.

The braid formed by the crossed wires 3 and 5 ' is stretched between the two opposite sides 6 of the frame by means of the spiral springs 7 and 8. According to the presented

009834/0691

Example are the springs 7, the (nioht shown) sitting / board supporting GefleclÄrteil keep elastic than the springs ■ 8 carrying the backrest · In fact, the weight distributed the inmates more than the seat board as Via the Rttcklehne .

In addition, the distance between the springs 7 and β can nioht the same and also not regular · The lumbar region can, for example, be better supported than another part of the body.

In order to prevent the wires 3 from slipping over the wires 5 and the generation of noise, the wires 5 can e.g. with a flexible or fibrous material S ^ and a twine, Paper binding thread, natural or synthetic »fibers, etc. · · be clothed or wrapped · The wires are then simply bent over, as can be seen in particular from Figure 3 · The intermediate wires 10 maintain a suitable distance between the wires 3. The wires 10 run parallel to the wires 5 and can consist of a material similar to the latter, they can also simply consist of string or of any striok be formed · The braid 2 is characterized by the particular shape of the springs 7 and 8, as it is clear from the figures 4 and 5 is borrowed, very easily built into the frame At the height of the seat board, the springs 7 can, for example, in the holes 11 drilled in the frame penetrate while the springs be fastened near the backrest to tabs or hooks 12 connected to the frame · The other ends of these springs are simply connected to the two end parts of the wires 5 of the braid. 009834/0491

The seat will then be covered accordingly * If desired, can it still be covered with cushions

It stands to reason that it is so very easy to find a hammock Seat images that distribute the weight of the occupant over a large area, dampen the shocks and the uncomfortable Avoids rocking frequencies.

The seat described can be completed by numerous improvements and accessories, without departing from the scope of the To leave the invention · For example, the shape and rounding of the frame can be adapted to the shape of the occupant's body. One can the superstructures on which the mesh is stretched, too attach to the frame in such a way that the seat is given the most comfortable and most suitable seating surface. In particular, can Such superstructures are preferably placed in the lumbar region in order to reduce the physical fatigue of the occupant in this very sensitive area of the Körjberg.

In addition, suitable means can be provided to the Adjust the height and inclination of the seat as required.

The braid can also be formed by wires that cross each other differently than is shown in the embodiment described e.g. with other than right-angled crossings and / or in wire directions that are not parallel to the frame sides are.

Of course, the invention is not limited to the embodiments described and illustrated, which only have been given by way of example.
