Description

The proposed solution relates to a standing seat which can be fastened to a wall of a vehicle and is set up to support an essentially standing person, as well as a seat arrangement having such a standing seat.

Standing seats are known in particular from the field of local public transport in the form of upholstered surface elements which are essentially set up to absorb forces acting orthogonally to the surface element. In particular, however, standing seats of the prior art are not able to support a person supporting themselves with respect to forces which act along an axis within a plane of the surface element.

The proposed solution is thus based on the problem of improving a standing seat for attachment to the wall of a vehicle with a view to supporting differently directed forces and thereby reducing the component volume, especially when not in use.

This problem is solved by a standing seat with the features of claim 1 and a seat arrangement with the features of claim 24.

Accordingly, the standing seat has a fastening part with which the standing seat can be fastened to a wall of a vehicle for intended use. In addition, the standing seat has a support part which is provided for supporting the hip area of a person and which is connected to the fastening part and, in an embodiment which minimizes the assembly effort, can be designed in one piece with the fastening part. In an embodiment that reduces the manufacturing costs, the one-piece fastening / support part can be implemented using a plastic in an injection molding process. Furthermore, the standing seat comprises at least a first and a second side part which can be pivoted relative to the fastening part. In this case, the first and second side parts can be transferred into a fixing position in order to produce a lateral fixation of a person who is supported on the support part. In this fixing position, for example, both side parts can each rest on one side of the hip area of the person to be supported or can partially encompass them. Furthermore, in order to reduce the component volume when not in use, the side parts can be pivoted into a neutral position in which they are essentially in a plane of extent with the support part. This results in the need for an adjusting mechanism which realizes the pivotable connection of the first and second side parts with the fastening part.

In an advantageous further development of the standing seat, the support part also has an adjustment option with regard to the position relative to the fastening part, the support part being adjustable at least between a creation and a second position. In the initial position, the support part extends essentially coplanar to the wall of the vehicle and thus serves, among other things, to support the person who is being supported with regard to forces directed orthogonally to the wall of the vehicle. In a second position, on the other hand, the support part is pivoted relative to the fastening part in such a way that a surface normal of the support part has a non-vanishing portion along the vertical. Thus, in the second position, the support part is set up to at least partially support a person who is supporting himself with regard to a force acting along the gravity of the earth.

A support part set up in this way can have an essentially square base area, the base area denoting an area which is described by an orthogonal projection of the support part created on the wall of the seat that is intended to be attached to the wall. In principle, however, all forms are conceivable which are suitable for supporting the forces caused by a person supporting himself in the sense of an appropriate level of comfort.

In different embodiments, the adjustment mechanism can be designed in such a way that the first and second side parts and the support part can be adjusted independently of one another and thus serve to achieve a particularly high degree of customizability with regard to the adaptation of the standing seat to a person who is supported. Alternatively, the first and second side parts and the support part can be adjusted in a coupled manner in order to enable extensive adjustment of the standing seat by a small number of adjustment actions.

The support part, which is fastened pivotably relative to the fastening part, can be fastened, inter alia, to the wall of the vehicle and / or have a corresponding articulated connection to the fastening part of the standing seat. If the pivotable support part is connected to the fastening part, it can be connected via a film hinge, in particular to avoid joints and to improve the manufacturing process, which reduces the flexural rigidity along a definable area and thus enables pivoting.

In one embodiment, the pivoting of the first and second side parts can be implemented with the aid of a spindle drive. This has, inter alia, a horizontal threaded rod which is arranged on a rear side, facing the wall, of the standing seat which is fastened to the wall in normal use. The threaded rod, which can be rotated by external force, has a first and a second slide, which can each be arranged behind a side part and translate the rod rotation into a linear displacement along the threaded rod. Such a linear displacement can be converted into a pivoting movement of the side parts by means of an articulated connection of a slide with a respective side part. In another embodiment, a slide with at least one support section facing the standing seat is supported on each side part. In this case, a spring load is applied to the side parts in such a way that the first and second side parts are pressed against one slide in each case, regardless of its position along the threaded rod. Furthermore, the rear sides of the first and second side parts are each designed in such a way that the slide moves in the direction of the threaded rod center, i.e. in the direction of the connection of each side part, with the fastening part and / or the support part, resulting in a pivoting of the side part relative to the fastening part and thus leads to the transition from the neutral position to the fixing position.

In a further embodiment, the standing seat has a motorization which is set up to effect the adjustment movement of at least the first and second side parts in an external force-controlled manner. It is also possible here that the motorization is additionally set up for the adjustment movement of the support part.

In order to control the motorization by a person, the motorization can have an operating element which is set up to enable manual control of the aforementioned adjustment and displacement movements.

In a further development of the proposed standing seat, the adjustment mechanism has an evaluation device which is coupled to the operating element and is set up to store and evaluate the manual controls of the aforementioned adjustment and displacement movements made via the operating element. For this purpose, the evaluation device can use a statistically based logic which, for example, derives an expected value of the aforementioned adjustment and displacement movements from the majority of the previous manually performed controls. This expected value thus describes a predicted preferred setting, which can consist, for example, of an angle of inclination of the support part in the second position and a pivot angle of the side parts with respect to the fastening part in the fixing position. In particular, through the recurring execution of manual controls in the sense of fine tuning, a self-learning logic for the continuous improvement of the predicted preferred setting can be implemented.

In addition, the adjustment mechanism can have at least one sensor element which is coupled to the motorization, for example to detect the presence of a person. Such a sensor element can be implemented by a tactile sensor in the area of the support part which is able to detect a person who is supported on the support part. In alternative solutions, the sensor element can also be set up for distance measurements based on light or sound. By coupling such a sensor that detects the presence of a person with the motorization of the adjustment mechanism, an adjustment and / or displacement movement of the standing seat induced by the presence of a person can consequently be implemented to improve the comfort of use.

In a further embodiment, the adjustment mechanism has at least one sensor element which is set up to detect user-specific data which are suitable for predicting a preferred setting. Such data can include, for example, the leg length, the hip width and / or the height of the person using the seat. The user-specific data can, among other things, be obtained by distance measurements supported by light or sound or read out from a storage unit. Such a memory unit can have an RFID transponder, for example, which is coupled to an individualized ticket for local public transport for the person using the seat.

In a similar way, such a storage unit can also be a mobile terminal assigned to the person using the seat, such as a smartphone with devices for radio-supported data transmission such as, for example, Bluetooth, WLAN or NFC.

In a further development of the standing seat, the adjustment mechanism has a combination of the evaluation device with a sensor for detecting user-specific data, the user-specific data only serving to identify the person using the seat. As a result, the logic of the evaluation device can restrict the statistical basic set of the preceding controls to those that can be assigned to the user, or one in the sense of logic apply appropriate weighting. The evaluation device can thus be set up to further increase the convenience of use to carry out a prediction of the preferred setting that is adapted to the respective user.

In a further variant, the user-specific data required for a preferred setting can be provided by a non-local storage unit in the form of an IT infrastructure. In addition to such a non-local storage unit embodied as a cloud storage device, another local storage unit can provide data for identifying the person using the seat.

Thus, after successful identification of the person using the seat, the adjustment mechanism can request the user-specific data necessary for a preferred setting from the non-local storage unit in order to make a user-specific preferred setting.

Furthermore, under certain circumstances, manual controls carried out by the person using the seat via the operating element can be used to update the user-specific data stored in the non-local storage unit in the sense of the self-learning logic.

In an alternative or supplementary development, it is also possible for the adjustment mechanism to have a combination of the evaluation device with at least one sensor element for detecting user-specific data such as leg length, hip width and / or body size. The user-specific data obtained by the at least one sensor element can thus be assessed by the evaluation device with regard to the measurement reliability. For this purpose, a correlation analysis of individual measurements with a statistical distribution is possible, for example. Such a distribution can in turn be determined from the set of all previous measurements or otherwise stored in the evaluation device. In the case of individual measurements that may be classified as unsafe, predictions by the evaluation device can replace the unsafe measurements on the basis of the statistical distribution and any existing measurements classified as safe.

In all of the aforementioned embodiments, in order to improve the comfort of use, the first and second side parts of the standing seat can each provide a support surface for supporting the arms of the supported person, which are particularly suitable in the fixation position for the arms of the person being supported, in particular the forearms, along the To support the gravity of the earth.

Furthermore, in an alternative variant, the first and second side parts can be articulated to the support part to realize a connection that is pivotable with respect to the fastening part, wherein the first and second side parts can be connected to the support part via film hinges to avoid gaps. This avoids the formation of joints, in particular joints with a width that can be varied by the adjustment mechanism, which reduces the risk of unwanted inclusion of textiles or body parts of people in the vicinity.

In a further development of the proposed solution as claimed, the standing seat has a displacement mechanism which allows the height of the support part and / or the first and second side parts to be adjusted based on the distance to the floor of the vehicle. A support of the hip region of a person using the seat is thus made possible, regardless of the size of the person. In particular, the standing seat attached to a wall for intended use can additionally or exclusively be set up to be moved based on the spacing of the support part from the wall of the vehicle. In this way, especially in combination with a pivotable support part, the standing seat takes up little space when it is not in use by largely resting the support part against the wall on the one hand and sufficient spacing to increase the pivoting range of the support part on the other. In a specific implementation, the displacement mechanism of the standing seat has at least one guide part for the spaced-apart connection of the fastening part to the support part at different distances predetermined by the displacement mechanism. Here, the guide part is connected to the rear side of the support part facing away from a supported person in normal use and can be moved along at least one spatial direction with respect to the fastening part.

Such a displacement mechanism can, for example, comprise a telescopic rod which, based on a longitudinal axis of the telescopic rod, is connected in a vertical orientation with the fastening part fastened to the wall during normal use and the support part. The fastening part can thus serve as an abutment for forces acting vertically and horizontally on the support part. For this purpose, the displacement mechanism can have a gear mechanism, which preferably has a large adjustment path in a continuously variable manner. In particular, the gear mechanism is set up to withstand vertical and horizontal maximum loads that are greater than those in the standing seat for each position of the standing seat that can be reached by moving along the travel path intended use by one person on the standing seat.

Such a gear mechanism can be implemented, for example, by a cable pull or a toothed rack, which can be set up to move the telescopic rod by an external force to increase the comfort of use. In addition, there is a large number of further embodiments of a gear mechanism which meet the claimed features and whose advantages and disadvantages result from the special applications of the proposed solution.

In order to achieve effective support on the wall of torques caused by a person supporting himself on the standing seat, it is particularly advantageous for embodiments with long travel paths accessible through the height adjustment if the guide part is relieved by at least one additional support element connected to the support part. Such a support element is used here for the torque-minimizing support of forces acting horizontally on the support part on the wall by minimizing the vertical distance between the forces acting horizontally on the support part and a connection point of the support element with the support part. In this case, the support element must be mounted on the wall such that it can be moved along the path of the support part predetermined by the movement mechanism.

Such a movable mounting of the support element, which can be set up to support horizontal forces in any direction, can be implemented, for example, by at least one linear guide fastened to the wall. Here, the at least one linear guide can be aligned parallel to the orthogonal projection of the displacement path of the support part predetermined by the displacement mechanism on the wall and the support element attached to the support part can be in engagement with the at least one linear guide.

In an alternative embodiment, which is characterized by a low installation effort and low production costs, the at least one support element is supported on the wall with at least one rotatably mounted rotating element. Thus, when the support part is displaced, the rotating element rolls along the displacement path specified by the displacement mechanism on the wall. In principle, a combination, for example in the form of rotating elements rolling in a link guide, is also conceivable for combining the advantages of both embodiments.

In a further embodiment, the standing seat additionally has a back part which is set up to support the back region of a person sitting on the standing seat. Such a back part can, for example, have an essentially square base area, the base area denoting an area in the following which is described by an orthogonal projection of the back part onto the wall of the seat that is intended to be attached to the wall. In principle, however, all forms are conceivable which are suitable for supporting the forces caused by a person supporting himself in the sense of an appropriate level of comfort.

The back part can either be fastened directly to the wall of the vehicle or have a connection to the support part and / or to the fastening part. In particular, the back part can be designed in one piece with the support part and / or the fastening part in order to avoid material joints which may interfere with use and to minimize the manufacturing and assembly costs.

In a further development of the proposed solution, the standing seat has a displacement mechanism which allows the height of the back part to be moved relative to the distance to the floor of the vehicle and the distance of the back part relative to the distance between the back part and the wall of the vehicle. This can enable the back region of a person using the standing seat to be supported regardless of the person's size. In a specific implementation of a back part not connected to the standing seat, the displacement mechanism has for this purpose a reflection of the components provided for moving the support part, which follow the above statements on the displacement mechanism of the standing seat. In particular, the back part here has its own fastening element for fastening to the wall of the vehicle, which serves as an abutment for forces that occur. In addition, the back part has a guide element for the spaced-apart connection of the fastening element to the back part at different distances predetermined by the displacement mechanism. Here, the guide element can be connected to the rear side of the back part facing away from a supported person during intended use and can be moved along at least one spatial direction with respect to the fastening element.

In principle, for all of the aforementioned embodiments of at least the support part, the side parts and the back part, an ergonomic shape and / or the use of upholstery are advantageous in the sense of a high level of comfort.

Furthermore, all of the aforementioned embodiments can have automated anti-trap protection, which in a first variant can be implemented by limiting the maximum current of the motorization. In this way, the movement and adjustment movements can be interrupted or appropriately reversed in the event of a blockage of the component to be moved or adjusted, in particular by textiles or body parts of people in the vicinity.

In a further development of the anti-trap protection, the anti-trap protection is effected as a result of the detection of unwanted trapping of textiles or body parts of people in the vicinity by the adjustment or displacement mechanism concerned. For this purpose, the surfaces, edges and joints relevant for such jamming have a suitable sensor system in order to be able to detect the jamming in a spatially resolved manner.

Such a sensor system can have, for example, pressure sensors, sensors integrated into textiles, buttons, and tactile or capacitive sensors. In particular in the case of embodiments according to the invention, in which a single motor effects the adjustment and / or displacement movement of several device components, such a sensory detection of trapping can improve the trapping protection compared to a simple current limitation of the electric motor.

For a further advantageous embodiment of the proposed solution, the standing seat in one of the aforementioned embodiments is part of a seat arrangement. In addition to the standing seat attached to the wall, the seat arrangement has an additional footrest which is positioned such that a person supporting himself on the standing seat can support himself with his feet on a footrest provided by the footrest. Here, the footrest surface can be inclined to the wall and thus to the person supported on the standing seat, which means that a surface normal of the footrest surface intersects a plane of the wall of the vehicle to which the standing seat is attached at an intersection. Thus, the contact pressure exerted by the person supporting himself on the standing seat can be increased and consequently an unwanted escape of the person supporting himself from the standing seat caused by unforeseen acceleration situations of the vehicle can be avoided. To further develop this effect, the footrest surface can also have an anti-slip coating.

A further development of the proposed seat arrangement has a position adjustment mechanism for the footrest, which is set up to adjust at least the alignment of the footrest surface relative to the floor of the vehicle. This means moving the imaginary point of intersection of the normal to the surface of the footrest surface with the wall of the vehicle to which the standing seat is attached when used as intended, horizontally and / or vertically. In particular, in addition to pivoting the footrest surface about one or more horizontal pivot axes, this can also include a translative movement of the footrest surface along the vertical.

In terms of a high level of comfort, such positional adjustments of the foot part predetermined by the position adjustment mechanism can be performed with the adjustment and movement of the first and second side parts of the standing seat and / or the adjustment and movement of the support part of the standing seat and / or the adjustment and movement of the back part of the Be coupled to the standing seat. Such a coupling can be set up mechanically or electronically, for example, in such a way that at least one of the aforementioned adjustment or displacement movements triggers the remaining coupled movements.

In the sense of increased contact pressure at least on the support part by the person supported on the seat arrangement as well as a high level of comfort, in one embodiment the coupling can also be set up in such a way that for each position of the footrest and the support part given by the coupled adjustment movement, an axis of extension of the support part along the wall and an inclination axis of the footrest pointing in the direction of the wall enclose a constant angle. This means in particular that at least one surface normal of the support part and at least one surface normal of the footrest intersect and enclose an angle that is independent of the coupled adjustment movement.

The attached figures illustrate possible variants of the proposed solution by way of example.

1a shows an embodiment of a proposed standing seat S. , especially for use in local public transport vehicles, in the neutral position. In the embodiment shown, the standing seat S. a fastener MP on, which is attached orthogonally to a wall and with a support part provided to support the hip area of a person SP connected is. The support part which extends over a large area and is arranged coplanar to the wall SP here has a square base with a horizontal alignment of two opposing borders. The two vertically running opposite borders are referred to below as the sides of the support part. On both sides of the support part SP are each found at a distance from the support part SP separated two side panels SiP1 , SiP2 which also have a square base and, in the neutral position shown here, are coplanar with the wall and with two each on the sides of the support part SP boundaries aligned in parallel are arranged.

As is particularly evident in 1b you can see the fastening part MP at the same time orthogonally with the flat extending support part intended to support the hip area of a person SP connected. Thus, the support part shown here is SP set up by forces acting essentially horizontally and orthogonally to the wall via the fastening part MP to be supported on the wall.

In 1c are the first and second side panels SiP1 , SiP2 the in 1a and 1b illustrated embodiment relative to the fastening part MP swiveling on the mounting part MP articulated via a bow rod. Here, one of the arch rods is fixed to the back of one of the side parts facing the wall SiP1 , SiP2 connected. Thus, the illustrated arrangement of the first and second side parts is used SiP1 , SiP2 in the neutral position, among other things, the reduction of the standing seat S. occupied space when not in use. To produce a lateral fixation of one on the support part SP supportive person can use the first and second side panels SiP1 , SiP2 be transferred into a fixing position, in which, for example, one side part SiP1 , SiP2 in each case rests on one side of the hip area of the person supporting himself or partially embraces it. For this purpose, the articulated connection of the bow rods with the fastening part can be set up in such a way that the pivotability the bow bars can be blocked manually or electronically in the fixing position.

In addition, the illustrated first and second side parts SiP1 , SiP2 in the neutral position, it can also be set up to apply forces acting essentially horizontally and orthogonally to the wall via the fastening part MP to be supported on the wall. For this purpose, the articulated connection of the first and second side parts SiP1 , SiP2 be designed with the fastening part in such a way that the first and second side parts SiP1 , SiP2 starting from a coplanar arrangement cannot be pivoted in the direction of the wall. For such an embodiment, for example, the articulated connection could have a stop element which correspondingly restricts the pivoting range of the bow bars.

In alternative embodiments, the first and second side parts SiP1 , SiP2 instead of the fastening part MP connected, on the support part SP be hinged, furthermore, the support part SP and the fastening part MP to reduce the assembly effort in one piece and be realized, for example, by a plastic in the injection molding process.

In 2a is the support part SP of the proposed standing seat S. relative to the fastening part MP pivotable about a horizontal connecting axis with the fastening part MP connected. Thus, the support part SP in particular adjustable between an initial position and a second position. In this embodiment, the support part is substantially rectangular in shape, the edges opposite in pairs having a horizontal or a vertical orientation. The first and second side panels SiP1 , SiP2 are, however, formed in the shape of a right-angled trapezoid, with each of the first and second side parts SiP1 , SiP2 with the longer of the parallel opposite border parallel to the sides of the support part SP is arranged such that the longer of the parallel opposite edges of the trapezoids the support part SP is facing. Along the facing edges of the first and second side parts SiP1 , SiP2 and the support part SP extends a film hinge FH , which is one of the first and second side panels SiP1 , SiP2 with the support part SP connects. This allows the formation of joints, in particular joints, with the adjustment mechanism AT THE variable width can be avoided, which minimizes the risk of unwanted inclusion of textiles or body parts of people in the vicinity.

In the initial position shown, the support part extends SP essentially as in 1a , 1b , 1c coplanar to the wall of the vehicle and thus serves, among other things, to support the person who is being supported with regard to forces directed horizontally and orthogonally to the wall of the vehicle. Furthermore, the creation shown reduces that caused by the support part SP occupied space volume.

In 2 B is the support part SP of the proposed standing seat S. as well as in 2a relative to the fastening part MP pivotable about a horizontal connecting axis with the fastening part MP connected. Furthermore, there is the adjustment mechanism AT THE on a rear side of the support part facing the wall SP with this, as well as in a manner not shown with the first and second side parts SiP1 , SiP2 connected in order to be able to adjust them from the neutral to the fixing position. As in 2 B shown, has the surface normal ASP of the support part SP a non-negligible vertical portion, whereby a person sitting on it can be supported at least partially with regard to forces acting along the gravity of the earth.

The support part SP In addition to the essentially flat shape shown here, they have any different shapes, as long as they are suitable for supporting the forces caused by a person supporting themselves in the sense of an appropriate level of comfort.

In 3 is the standing seat S. essentially as in 2a and 2 B but shown in a position attached to the wall for intended use. For adjusting the first and second side panels SiP1 , SiP2 from the neutral to the fixing position is on the back of the support part SP the adjustment mechanism AT THE with the support part SP connected. In the embodiment shown here, the adjustment mechanism AT THE including a horizontal threaded rod AT 3 on which one is on the back of the standing seat S. on the support part SP is arranged. The threaded rod rotatable by external force AT 3 also has a first carriage AM1 and a second slide ON 2 on, each behind one of the first and second side panels SiP1 , SiP2 can be arranged and the rotation of the threaded rod AT 3 into a linear displacement along the threaded rod AT 3 translate. In the embodiment shown here, one slide is supported in each case AM1 , ON 2 with at least one of the standing seats S. facing support section AM11 , AM21 of the slide on one at a time back SiP11 , SiP21 the side panels SiP1 , SiP2 from. Here are the side panels SiP1 , SiP2 acted upon by a spring load in such a way that the first and second side parts are pressed on SiP1 , SiP2 to one sled each AM1 , ON 2 regardless of its position along the threaded rod AT 3 is realized. Furthermore, here is the back SiP11 , SiP21 the first and second side panels SiP1 , SiP2 each designed in such a way that a method of the slide AM1 , ON 2 in the direction of the middle of the threaded rod, that is, in the direction of the connection of each of the first and second side parts SiP1 , SiP2 with the fastening part MP and / or the support part SP for pivoting the respective side part SiP1 , SiP2 relative to the fastening part MP and thus leads to the transition from the neutral position to the fixing position. Alternatively, the slide can be used to transfer the linear displacement AM1 , ON 2 in a pivoting movement of the side parts SiP1 , SiP2 basically also an articulated connection of each slide AM1 , ON 2 each with one of the first and second side panels SiP1 , SiP2 suitable.

The further development of the standing seat S. to adapt to the body size of different sizes the standing seat S. people using it is in 4a shown in rear view. Here is the support part SP with a substantially square base with the trapezoidal first and second side parts SiP1 , SiP2 as in 2a each shown via a film hinge FH connected.
