TECHNICAL FIELDThe invention relates generally to seating apparatuses, and specifically to a seating apparatus with a settable supporting unit that is provided for integration in a seat component.
BACKGROUNDA seating apparatus with a settable supporting unit, which is provided for integration in a seat component formed by a backrest and which includes a pneumatic, inflatable supporting means, is known.
However, there is a need for a seating apparatus with a settable supporting unit that is integrated in a seat component and that has at least one pneumatic supporting means and at least one mechanical supporting means, with the pneumatic supporting means being coupled to the mechanical supporting means for actuation of the mechanical supporting means.
SUMMARYIn view of the above, a seating apparatus is provided with a settable supporting unit that is integrated in a seat component and that has at least one pneumatic supporting means and at least one mechanical supporting means.

According to another exemplary embodiment, a seating apparatus is provided with a settable supporting unit for integration in a seat component. The settable supporting unit has at least one adjustable, mechanical supporting means. A setting unit is provided for setting the supporting unit in an at least partially automated manner as a function of at least one characteristic variable.
Another exemplary embodiment includes a method for setting a supporting unit that is provided for integration in a seat component and that has at least one mechanical supporting means. According to the method, the supporting unit is set as a function of at least one characteristic variable.
Further advantages emerge from the following description of the drawings. The drawings illustrate exemplary embodiments of the invention and, together with the description and the claims, contain numerous features in combination. One skilled in the art will also consider the features individually and put them together to form meaningful further combinations.
In the drawings:
Referring now to the drawings in which like numerals reference like parts,
As used throughout, “mechanical supporting means” is to be understood, in particular, as meaning a means which is formed by a body and, in particular in comparison to a flexurally soft component, such as a flexurally soft casing of a pneumatic supporting means and a flexurally soft fabric upholstery, is suitable and, in particular, also provided for the purpose of transmitting functional forces transversely with respect to a surface extent. In this case, the means which is formed by the body is advantageously designed such that it is flexurally rigid transversely with respect to its surface extent and/or, particularly preferably, such that it is elastically deformable, in particular by more than one millimeter by the weight of a passenger in the use situation. An elastic deformability enables advantageous adaptations and transitions to be achieved.
The mechanical supporting means here can be produced from various materials appearing expedient to a person skilled in the art, such as, in particular, from composite materials, such as carbon fiber materials, glass fiber materials, and/or also from one or more plastics, for example by it being produced by multi-component injection molding, etc. Furthermore, “provided” is to be understood as meaning specially equipped and/or designed.
By means of a corresponding configuration according to the invention, large adjustments can be realized in a simple manner using small quantities of air, to be precise, in particular if the mechanical supporting means is formed by a pivotably mounted flap. Advantageous adaptations can be realized with little expenditure of energy, within short periods of time. Furthermore, the pivotable mounting enables advantageous transitions to be achieved. In principle, however, mechanical supporting means guided movably in an at least partially translatory manner would also be conceivable.
The mechanical supporting means can be designed such that they can be set manually and/or via additional actuators. However, the pneumatic supporting means is particularly advantageously coupled to the mechanical supporting means and is provided for actuation of the mechanical supporting means, as a result of which additional, in particular heavy actuators can be avoided.
In a further refinement, the mechanical supporting means may have a changing rigidity, in particular flexural rigidity, in the direction of at least one surface extent, thus enabling different supporting effects to be obtained in a specific manner over the surface extents.
Furthermore, a seating apparatus may comprise a settable supporting unit which is provided for integration in a seat component and comprises at least one adjustable mechanical supporting means, the seating apparatus having a setting unit which is provided for setting the supporting unit in an at least partially automated manner as a function of a characteristic variable. As a function of the characteristic variable, an advantageous setting can be realized and the comfort can be increased. By means of the combination of at least one mechanical supporting means and at least one pneumatic supporting means, various supporting effects can advantageously be obtained, and, in particular, an advantageously large setting range can be achieved, and therefore various settings can advantageously be realized as a function of at least one characteristic variable.
In this case, the setting unit can set the supporting unit as a function of various characteristic variables appearing expedient to a person skilled in the art, but, particularly advantageously, as a function of a position of the seat component and, in particular, as a function of a position of the backrest. Substantially changing demands imposed on the supporting unit can therefore advantageously be taken into account by changing a position of a seat component and, in particular, the position of a backrest.
The supporting unit preferably forms a settable lordosis support such that an advantageously large setting range, in particular a setting range dependent on a characteristic variable, can be achieved, in particular in the lower region of a backrest.
In a further refinement, the supporting unit may have at least two pneumatic supporting means for obtaining different settings, thus making it possible, in a structurally simple manner, to obtain different supporting effects, to be precise, in particular if the pneumatic supporting means have coupling points to the mechanical supporting means, which coupling points are spaced apart at different distances from a pivot axis of the mechanical supporting means.
Furthermore, the setting unit may comprise a valve unit, thus making it possible, via the control and/or regulation of a quantity of air in a pneumatic supporting means, to realize an adjustment in a simple manner, to be precise, by air being supplied via the valve unit and/or, in particular, by air being let out via the valve unit from a certain position of the seat component or by a pneumatic supporting means being vented.
Referring again to
The three pneumatic supporting means 14, 16, 18 are arranged between the backrest fabric 32 and the mechanical supporting means 20, are coupled to the mechanical supporting means 20 via a respective coupling point and are provided for actuation of the mechanical supporting means 20 (
The pneumatic supporting means 16, 18, which are of kidney-shaped design, are arranged in a left and right region of the backrest below the pneumatic supporting means 14, i.e. on a side thereof which faces away from the pivot axis 26, and are coupled in the lower region of the mechanical supporting means 20 to the same via coupling points. The coupling points of the pneumatic supporting means 16, 18 are therefore spaced apart further from the pivot axis 26 than the coupling point of the pneumatic supporting means 14.
The mechanical supporting means 20 can be deformed elastically transversely with respect to its main surface extent and, in its surface extent 22, i.e. in the direction of the longitudinal axis 38 of the backrest, has a continuously changing flexural rigidity, to be precise, the flexural rigidity increases continuously from the upper region of the mechanical supporting means 20 in the direction of the lower region of the mechanical supporting means 20, which region faces the seat base 36. For this purpose, the mechanical supporting means 20 is designed to be thinner-walled in the upper region or in the region of the pivot axis 26 and therefore to have a lower flexural rigidity and to be thicker-walled in the lower region or in the region facing away from the pivot axis 26 and therefore to have greater flexural rigidity, as a result of which particularly advantageous adaptability can be achieved in the upper region of the mechanical supporting means 20 and an advantageous transmission of force can be achieved in the lower region of the supporting means 20.
Furthermore, the seating apparatus has a setting unit 24 with a valve unit 46 which is provided to set the supporting unit 12 in a partially automated manner as a function of a position of the backrest.
If the backrest is in its upright position or in a position associated with starting and landing of an aircraft, the pneumatic supporting means 14 can be filled and also emptied by a passenger via an operating unit (not illustrated specifically) by means of an electric pump 42 via the valve unit 46 of the setting unit 24, and therefore the mechanical supporting means 20 can be actuated (
The relatively low inherent rigidity of the mechanical supporting means 20 in the upper region means that, in the upper region of the same, an advantageously extensive support of the lordosis of the passenger is brought about. The pneumatic supporting means 14 is coupled in a relatively flexurally soft region to the mechanical supporting means 20 such that the latter can advantageously be deformed elastically about the pneumatic supporting means 14, as indicated by dashed lines in
In the upright position of the backrest, a connection between the pump 42 and the pneumatic supporting means 16, 18 is prevented via the valve unit 46 of the setting unit 24, and the pneumatic supporting means 16, 18 are vented via the valve unit 46.
If the backrest is brought into an inclined position, a connection between the pump 42 and the pneumatic supporting means 16, 18 is produced via the valve unit 46 of the setting unit 24 and a connection between the pump 42 and the pneumatic supporting means 14 is interrupted. Furthermore, the pneumatic supporting means 14 is vented. The pneumatic supporting means 16, 18 can now be filled and emptied by the passenger (
If the backrest is brought again into its upright position by the passenger, a setting movement is transmitted by the backrest to the valve unit 46 of the setting unit 24 by means of a mechanical unit 44, and the pneumatic supporting means 16, 18 are vented or air is let out of the pneumatic supporting means 16, 18, thus ensuring that a seat reference point is maintained. In addition, the pump 42 is connected again to the pneumatic supporting means 14. The pneumatic supporting means 16, 18 are therefore associated exclusively with inclined positions of the backrest while the pneumatic supporting means 14 is exclusively associated with an upright position, as a result of which only small quantities of air are ever required. In principle, however, other associations appearing expedient to a person skilled in the art are also conceivable; in particular, the supporting means 14 could be designed such that it can be inflated even in an inclined position of the backrest, for example in order to obtain an additional supporting effect.
The aforementioned exemplary embodiments are applicable for use in all seats, such as in seats for long-distance coaches, ferries, halls, convention halls, as well as in vehicle seats and, particularly advantageously, in aircraft seats.
The invention is described herein in detail with particular reference to presently preferred exemplary embodiments. However, it will be understood that variations and modifications can be effected within the scope and spirit of the invention.
