US 20090236896 A1Abstract
The invention is based on a seat arrangement, in particular for an aircraft seat, with a back rest unit. It is proposed that the back rest unit has at least one stiffening means in a seat region.
[0001] The invention is based on a seat arrangement according to the precharacterizing clause of claim 1.
[0002] A seat arrangement with a backrest unit and a fixing unit is already known, said fixing unit being provided for locking the backrest unit in a plurality of positions. For this purpose, the fixing unit has fixing means arranged symmetrically on both sides.
[0003] The invention is based on a seat arrangement, in particular for an aircraft seat, with a backrest unit.
[0004] It is proposed that the backrest unit has at least one stiffening means in a seat region. In this case, a seat region is to be understood in particular as meaning a region which is arranged in a seat, as viewed in the operational position thereof, below a lumbar region of the backrest unit, which lumbar region is provided in particular for lumbar support. By means of an appropriate configuration, weight, components, costs and/or outlay on installation can be saved. In particular, a fixing unit which is provided for locking the backrest unit in at least one position and which has only a single fixing means arranged on one side, in particular on one side of the backrest unit, can be provided. A fixing means can be avoided on a second side of the backrest unit and, in association therewith, components, weight, costs and outlay on installation can be saved.
[0005] In a further configuration of the invention, it is proposed that the stiffening means extends from a first side region into a second side region of the backrest unit, as a result of which the two side regions can advantageously be coupled via the stiffening means, and forces and/or moments acting on the one side region of the backrest unit can be transmitted to the other side region of the backrest unit by means of the stiffening means and therefore stiffening can be achieved. In this case, a side region of a backrest unit is to be understood in particular as meaning a region defined by a support part of the backrest unit.
[0006] Furthermore, it is proposed that the seat arrangement has a kinematic unit via which the backrest unit is coupled to a seat frame, as a result of which a movement of the backrest unit can advantageously be coupled to a seat base.
[0007] If two kinematic parts of the kinematic unit are coupled via the stiffening means, an advantageous force flux can be obtained, to be precise in particular if the stiffening means is formed by a torsion rod which is provided for transmitting a torsional moment. Furthermore, a force introduced on the one side region of the backrest unit can be transmitted in a particularly space-saving manner to the second side region by a stiffening means formed by a torsion rod.
[0008] The stiffening means can furthermore be integrated in a particularly space-saving manner if the same is coupled in a rotationally fixed manner to at least one kinematic part formed by a pivotable lever, and preferably to at least two kinematic parts of the kinematic unit, which kinematic parts are formed by pivotable levers, and in particular if the stiffening means is arranged coaxially with respect to a pivot axis at least for one kinematic part formed by a lever.
[0009] The stiffening means is preferably formed by a tube, thus making it possible to achieve a component having a high degree of rigidity, in particular a high degree of torsional rigidity, and a low weight, which component is advantageously suitable for transmitting a torque or torsional moment, to be precise in particular if said component is designed with a round cross-sectional area.
[0010] In a further configuration of the invention, it is proposed that the seat arrangement comprises a seat support arrangement with an individual seat supporting bar unit, as a result of which components and weight can be saved and in addition a required construction space can be reduced and a “living space” can be increased.
[0011] Owing to the possible reduction in weight, the seat arrangement according to the invention is suitable in particular for an aircraft seat, but in principle a corresponding seat arrangement can also be used in other seats appearing suitable to a person skilled in the art, such as, in particular, in motor vehicle seats, seats for lecture halls, etc.
[0012] Further advantages emerge from the description below of the drawing. The drawing illustrates an exemplary embodiment of the invention. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them to form meaningful further combinations.
[0014] FIG. 1 shows a schematically illustrated aircraft seat with a seat arrangement according to the invention in a side view, and
[0015] FIG. 2 shows the aircraft seat from FIG. 1 from above.
[0016] FIG. 1 shows a schematically illustrated aircraft seat 10 with a seat arrangement according to the invention, in a side view. The seat arrangement comprises a backrest unit 12 which is coupled via a kinematic unit 22 and via a seat support arrangement 34 to a seat frame (not illustrated specifically) which is provided to be mounted on a cabin floor of an aircraft. The seat support arrangement 34 comprises an individual seat supporting bar unit 36 which is coupled or connected fixedly to supporting bars 38, 40 of the kinematic unit 22 (FIGS. 1 and 2).
[0017] The backrest unit 12 has a stiffening means 16 which is arranged in a seat region 14 below a lumbar region 68 for the lumbar support of a passenger, to be precise in a front seat base region in front of the seat supporting bar unit 36 and which extends transversely with respect to the flying direction from a first side region 18 into a second side region 20 of the backrest unit 12, or from one side of the seat base region to an opposite side of the seat base region.
[0018] The backrest unit 12 comprises a substantially U-shaped support unit 42 extending into a head region of the backrest unit 12. On a side facing the seat base region, the sides of the backrest unit 12 have a respective support part 44, 46 which is coupled rigidly to the support unit 42 and is coupled rigidly in each case to support parts 48, 50 of the backrest unit 12, which support parts extend into the seat base region.
[0019] The support parts 48, 50 are coupled in a rear seat base region via pivotably mounted levers 52, 54 of the kinematic unit 22 to the supporting bars 38, 40 of the kinematic unit 22. Furthermore, the support parts 48, 50 are coupled pivotably in coupling points 56, 58 in a front seat base region to kinematic parts 24, 26 of the kinematic unit 22, which kinematic parts are formed by levers and in turn are coupled pivotably in coupling points 60, 62 to the supporting bars 38, 40.
[0020] The stiffening means 16 formed by a tubular torsion rod is provided for transmitting a torsional moment between the two kinematic parts 24, 26, which are designed as levers, and is arranged for this purpose coaxially with respect to a pivot axis 28 of the kinematic parts 24, 26, is mounted rotatably in the supporting bars 38, 40 and is connected in a rotationally fixed manner to the kinematic parts 24, 26, to be precise via respective transverse bolts 64, 66 extending through the stiffening means 16 and respectively through the kinematic parts 24 and 26.
[0021] Furthermore, the seat arrangement comprises a fixing unit 30 which is provided for locking the backrest unit 12 in a plurality of positions, the fixing unit 30 having an individual fixing means 32 arranged on one side in the region of the supporting bar 38. A fixing means is not arranged in the region of the supporting bar 40. The fixing means 32 comprises a piston which is guided in a hydraulic cylinder 70 and is coupled via a piston rod 72 to a free end of the support part 48. On the side facing away from the free end of the support part 48, the hydraulic cylinder 70 is supported in a support part 74 fastened to the supporting bar 38. A support part 76 corresponding to the support part 74 is fastened to the supporting bar 40. The mounting of the support parts 48, 50 within the kinematic unit 22 is identical except for the fixing unit 30, and the kinematic unit 22 is of identical design in the side regions of the seat base apart from the fixing unit 30. If a manual load occurs in a side region of the backrest unit 12, said manual load is transmitted as a torque or torsional moment via the levers or kinematic parts 52, 24 or 54, 26 facing said side region to the stiffening means 16 and via the stiffening means 16 to the opposite side region of the backrest unit 12, as a result of which the backrest unit 12 is stiffened, in particular compared to a corresponding configuration without the stiffening means 16.
