Description

Technical FieldA mobile mobility aid, in particular an electric separator mobile, having a cabin for a person operating the mobility aid is described.Background ArtMobile mobility tools are demanded in particular by persons with limited mobility and independence. With aging society, the proportion of people who rely on such solutions due to their limited mobility and independence increases. Accordingly, in the future, an increasing need for drivable mobility tools is to be assumed.Drivable mobility tools are, however, also used by Pendlers, in particular in urban areas. Further users of such mobility tools are users of long-distance recreational facilities such as golf courses or heel facilities.A large part of these mobility tools is operated by an electronic drive, such as an electric motor, with an electrical energy store, such as a battery. However, internal combustion engines, fuel cells, mechanical drives or hybrid drives from the aforementioned drive types are also conceivable.Previously known are mobile mobility tools which have a cabin for a person operating the mobility tool, wherein the cabin has a steering device in order to actuate a steering mechanism and thus to control the mobility tool.The known mobility tools are present in two embodiments. The former are designed to be fully open, i.e. have no or only negligible coverage of the cabin with respect to the external environment, in particular on the top side, the front side, the rear side, the left side and the right side of the cabin. Fully open cabins do not protect the occupants of the mobility aid from external environmental influences such as rain, snow, dirt, wind, extreme temperatures and other influences. In the event of accidents, the occupants of open cabins are likewise poorly protected. The mobility aid is deficient in crumple zones which protect the occupants from injuries. Mobility tools are thus also deficient in boundary installations which prevent them from falling out of the cabin of the mobility tool.The latter are designed to be completely closed, i.e. they have a complete covering of the cabin with respect to the external environment, in particular on the upper side, the front side, the rear side, the left side and the right side, but also on the underside. Due to the completely closed design, the ventilation of the cabin interior is very greatly restricted, so that active systems have to be used for ventilation. In addition, such mobility aids have a significantly higher own weight due to the additional body components, which in particular also ensures a higher energy consumption and increases the manufacturing costs.Technical DescriptionProceeding from this situation, it is an object to overcome the disadvantages of the previously known designs of mobile mobility tools and to create a mobility tool which has a certain proportion of safety and protection facilities and at the same time a low weight, a low energy consumption, low production costs and good ventilation.The aforementioned object is achieved by the features of the independent main claim. Advantageous embodiments are specified in the dependent claims. Insofar as technically possible, the teachings of the subclaims can be combined as desired with the teachings of the main and dependent claims.In particular, the object is accordingly achieved by a mobile mobility aid, in particular an electric separator vehicle, having a cabin for a person operating the mobility aid, the cabin having an underside, front side, upper side, rear side, left side, right side, wherein the front side of the cabin is oriented in the direction of travel, wherein the cabin in particular has a steering device and / or a seat device, wherein the cabin is completely enclosed at least on the underside, the front side and the upper side of the cabin and wherein the right side and the left side of the cabin are substantially open.Advantageous aspects are explained below and preferred modified embodiments are described further below. Explanations, in particular regarding advantages and definitions of features, are basically descriptive and preferred, but non-limiting examples. Where an explanation is limiting, this is expressly mentioned.A mobile mobility aid is a mechanically or electrically operated device which serves to enable persons with limited mobility to travel safely and independently. A mobility aid usually has a supporting structure, a drive unit, a control system and at least three contact points with the ground, such as wheels, in order to ensure stability and mobility. The device may include additional functions, such as seating systems, handles, spring systems, brake mechanisms, lighting units, and / or daily life support accessories.A cabin is a closed or partially closed structure which protects the driver of a mobility aid from external influences such as weather conditions, dust and / or noise and at the same time enables ergonomic operation and comfortable movement. It is usually fixed by the outer casing surrounding it. In this case, it can be delimited by a seat device, fixed and door systems, a roof structure, a front body, a rear body, a floor plate and / or frame structure and other conceivable arrangements.A steering device is an apparatus or a system that enables the direction of travel of a mobility aid to be controlled. It comprises mechanical, and / or electrical and / or electronic components that implement the movement of the steering mechanisms, such as the wheels and / or axles, according to the inputs of the driver. The steering device is designed to provide precise, safe and intuitive control, particularly for persons with limited physical mobility. The steering device can be operated via a steering wheel, a steering rod, a joystick or via keys or by touch inputs. The movement input can be transmitted to the steering mechanisms either purely mechanically, purely electrically or mechanically with electronic assistance.A seating device is a device that is integrated in the mobility aid and supports the user ergonomically, safely and comfortably during the trip. The seat device usually has a seat surface, a back support device, optional armrests and headrests and devices for height, inclination or position adjustment. It may include additional safety and comfort features to meet the specific needs of persons with limited mobility. For example, additional upholstery, a seat heater, a vibration damping, additional handles and holders or further devices are conceivable.In particular, the cabin is completely enclosed at least on the underside, the front side and the top side of the cabin. Completely enclosed means a structural design of the cabin of a mobility aid in which the respective side of the cabin, i.e. for example the underside, top side, front side, rear side, left side and / or right side, is completely covered or closed off by fixed, closed structures or structural elements, so that there are no openings, gaps or passages which could impair protection against external influences. With the exception of this, openings are provided for, for example, technical feedthroughs for cables, axles or the like, provided they are sufficiently sealed.Specifically, the right side and the left side of the cabin are substantially opened. Substantially open in this context means a configuration of the respective side of a cabin, i.e. for example the underside, top side, front side, rear side, left side and / or right side, in which the corresponding side of the cabin does not have any fixed or closed elements, so that there is unrestricted access to the interior space. In particular, no doors, windows or other structural obstacles are present in the corresponding areas of the cabin. Thus, the respective sides are fully open freely and continuously open. Movable elements such as hinged mirror structures, hinged armrests, removable covers, as well as safety-related elements such as support rods, crash guards or other functional devices may be present as long as they do not substantially obstruct access.According to a modified embodiment, it is provided that the cabin has a base plate and / or a frame structure on the underside. A floor panel can be easily mounted and simplifies the mounting of further superstructures and components above the floor panel. A frame construction, on the other hand, offers a high structural stability with a simultaneously low weight. Frame structures can be constructed in modular fashion, so that a plurality of variant embodiments can be realized without complicated modifications. Mobility tools with a combination of base plate and frame structure are also conceivable in order to benefit from the advantages of both embodiments.According to a modified embodiment, it is provided that the base plate has a profiled foot rest. A profiled foot rest has structured, corrugated or another shaped surface and thus offers advantages with regard to safety, comfort and functionality. A profiled surface offers better support for more stability and against undesired slipping off, in particular in the case of moisture or moisture. Moreover, a profiled surface can improve the drainage of water and dirt, thereby producing a self-cleaning effect.According to a modified embodiment, it is provided that the base plate has a cup-shaped receiving means for receiving a foot section of a walking aid, wherein the receiving means is connected to the base plate and / or frame structure. The cup-shaped receiving means completely and securely encloses the foot section of a walking aid. The receiving means thus reduces the risk that the walking aid will slip or become detached from the anchoring of the holding device in the event of unintentional contacts. Furthermore, the driver is also protected from undesired direct contact with the foot section of a walking aid, which may be soiled or wet if necessary.According to a modified embodiment, it is provided that the cabin has at least one lateral boarding edge, wherein the lateral boarding edge is arranged in particular on the floor panel and / or frame structure. A unique lateral boarding edge may serve as an optical aid for people with limited mobility when boarding the mobility tool.According to a modified embodiment, it is provided that the floor panel has a lateral protrusion on one side or on both sides as a boarding aid, wherein the corresponding lateral protrusion extends at least partially along the lateral boarding edge of the cabin.A lateral protrusion means a structural element arranged laterally on the base plate and protruding there upwards, to the side or downwards. A lateral protrusion, which extends at least partially along the boarding edge, helps both boarding and disembarking and, in particular, allows people who rely on walking aid to use the mobility aid without additional aid by providing a second step, in particular at a different height than the floor panel.According to a modified embodiment, it is provided that the cabin has a planar roof construction on the upper side and this completely encloses the cabin on the upper side. Such a flat roof construction offers extensive protection against various weather conditions, such as rain, snow, wind, dust, dirt or direct solar radiation. Furthermore, occupants are also protected from falling objects such as branches of trees and dirt. The flat roof construction enables a more uniform load distribution and thus increases the overall stability of the mobility aid. Together with ironing means, it can also serve as a rollover protection system. In particular, a planar roof construction offers a possibility of mounting solar modules on the roof construction or integrating them into the same without great investment costs. The range of the mobility aid could thus be increased.According to a modified embodiment, it is provided that the planar roof construction has at least one dome-shaped region, preferably two dome-shaped regions. Dome-shaped regions refer to structures or sections typically characterized by a curved, curved surface that rises from the base to a central point and then smoothly narrows or expands. Dome-shaped regions are generally symmetrical. The curvature is uniform throughout the structure, resulting in an optical harmonic shape. In the roof construction, the dome-shaped areas increase head clearance for the occupants located in the cabin. A better load distribution is achieved by the dome shape, whereby the overall stability is increased. In particular, however, the coupling shape also better dissipates rain, snow and dirt falling onto the roof construction, with the result that a self-cleaning effect is produced.According to a modified embodiment, it is provided that the planar roof construction has four outer edges, wherein the roof construction has a roof construction edge lip on at least one outer edge, preferably on two or three outer edges, wherein the at least one roof construction edge lip forms at least one outlet channel with the roof construction. The roof construction edge lip minimizes spray water to the sides in the event of rain and prevents uncontrolled outflow of, for example, rainwater via the outer edges of the roof construction. Instead, rainwater can collect in the drain channel between the roof construction edge lip and the roof construction and then flow off in a controlled manner to the front side of the cabin and flow off from there along a front pane edge to the front body. Alternatively, however, it is also conceivable for the rainwater to flow off to the rear side of the cabin. The selective removal of water and dirt prevents water and / or dirt from splashing from the roof structure when it flows down into the cabin of the mobility aid, which improves the cleanliness of the cabin, whereby in particular exposed interior areas are kept dry and whereby water accumulations at undesired locations are reduced. Due to a certain design freedom in the roof construction edge lip, it can be designed such that the aerodynamics of the mobility aid are improved and / or a seamless visual integration of the roof construction edge lip into the overall appearance of the mobility aid results.According to a modified embodiment, it is provided that the mobility aid has at least one removable skirt, wherein the left side is at least partially closable by a first removable skirt; and / or wherein the right side is at least partially closable by a second removable skirt. Partially closable means that the skirt closes a region of a cabin side as required, other parts remaining open. Thus, on the one hand, a targeted protection of the interior and / or occupants from environmental influences can be achieved and, at the same time, another function, such as, for example, a sufficient ventilation, a sufficient visibility, the accessibility or other functions, can be ensured. The protection of the cabin can thus be optimally and flexibly adapted to the environmental conditions. A removable skirt means that the skirt is not permanently attached to the mobility implement, but rather is attached only temporarily, and can easily be removed if necessary. A releasable connection is provided here, which is configured in particular in a force-fit, form-fit or force-fit manner. Zippers, hooks, clips, pushbuttons, magnets, hook-and-loop connections and / or screws are conceivable. Other connections are also conceivable. The detachable nature of the connection ensures a certain modularity, which offers the user advantages with regard to flexibility, personalizability and exchangeability. Different skirts are also conceivable during journeys in city traffic, in rural traffic and in off-road traffic. Not least, safety-relevant aspects can also be addressed with a skirt. Depending on the configuration, a skirt can prevent occupants from falling out of the cabin in the event of a collision or a sharp cornering.According to a modified embodiment, it is provided that the rear side is at least partially closable by a third removable skirt. Partially closable means that the skirt closes a region of a cabin side as required, other parts remaining open. Thus, on the one hand, a targeted protection of the interior and / or occupants from environmental influences can be achieved and, at the same time, another function, such as, for example, a sufficient ventilation, a sufficient visibility, the accessibility or other functions, can be ensured. The protection of the cabin can thus be optimally and flexibly adapted to the environmental conditions. A removable skirt means that the skirt is not permanently attached to the mobility implement, but rather is attached only temporarily, and can easily be removed if necessary. A releasable connection is provided here, which is configured in particular in a force-fit, form-fit or force-fit manner. Zippers, hooks, clips, pushbuttons, magnets, hook-and-loop connections and / or screws are conceivable. Other connecting means are also conceivable. The detachable nature of the connection ensures a certain modularity, which offers the user advantages with regard to flexibility, personalizability and exchangeability. Different skirts are also conceivable during journeys in city traffic, in rural traffic and in off-road traffic. Not least, safety-relevant aspects can also be addressed with a skirt. Depending on the configuration, a skirt can prevent occupants from falling out of the cabin in the event of a collision or a sharp cornering.In particular, the first, second and / or third removable aprons can be connected to one another; releasably, for example by means of a Velcro or a zipper, or non-releasably, for example sewn or in any desired manner in one piece.According to a modified embodiment, it is provided that the mobility aid has a releasable closure mechanism, in particular a zipper, in order to fix at least one removable skirt to the roof construction. The detachable nature of the connection ensures a certain modularity, which offers the user advantages with regard to flexibility, personalizability and exchangeability. Different skirts are also conceivable during journeys in city traffic, in rural traffic and in off-road traffic. A zipper is particularly advantageous because it is easy and quick to operate with limited fine motor capabilities and low power, because it makes a continuous connection without interruptions, because it can be made water impermeable and because it is particularly durable. A zipper is also particularly resistant to unintentional loosening of the connection.According to a modified embodiment, it is provided that the at least one removable skirt is at least partially made of flexible material and the at least one removable skirt can be rolled in, wherein the roll-in skirt can be fixed to the roof structure in the rolled-in state via a connecting means, in particular a snap-in buckle. The advantage of a flexible skirt material is that the skirt can be collapsed or rolled up to a small pack size when not in use and thus easier to store. Packing dimensions are understood to mean the space requirement in length×width×height of a folded object. Due to the flexibility, the skirt can easily be guided over add-on parts such as armrest, handle or mirror structures and thus be adapted to different contours and geometries. Due to the flexibility, the skirt can be compactly rolled in, in particular, also in the assembled state. As a result, the covered surface can be variably adjusted by the skirt on the one hand and adapted to the circumstances, and on the other hand the skirt can also be stored in a completely rolled-up manner in the region of the outer edge of the roof construction. Fixing a skirt, which is rolled up as described, to the roof structure by a connecting means allows the occupant to reduce the skirt briefly to a minimum covering surface without having to remove the skirt completely. Particularly suitable connecting means are plug buckles. Plug-in buckles can be operated particularly quickly, intuitively and easily with one hand by simple insertion and unlocking, even with limited fine motor capabilities. In combination with tensionable straps, a particularly easily adaptable connection for fixing rolled-in skirts can be realized therewith. Plug-in buckles are also cost-effective to produce, easily replaceable and durable.According to a modified embodiment, it is provided that the cabin has a front window and a front body on the front side. The windshield offers effective protection against wind, rain and snow, which facilitates the use of the mobility aid under various weather conditions. However, it also protects the driver from dust, insects, stone blows and other objects. The front window may be equipped with UV protection in order to protect the occupants from solar radiation.The front body enhances the stability of the mobility aid in the front area, as a result of which the occupants are protected in the event of an accident, in particular in the event of a frontal collision. The front body also forms the basis for the assembly of headlights, high beam lights, indicators, windscreen wipers and / or mirror constructions.Front windshield and front bodies can in particular also be configured to be aerodynamically advantageous, so that the air resistance of the mobility aid is reduced and the energy efficiency is increased.According to a modified embodiment, it is provided that the front body has at least one windshield wiper. A windshield wiper is an additional device for the safety and functionality of mobility tools. A windshield wiper significantly improves visibility in poor weather conditions by removing dirt, water, snow, dust and the like from the windshield and keeping the windshield clean overall. By cleaning the pane, the mobility aid can be used independently of the weather. Furthermore, accidents in road traffic can be avoided by a clear view. A windshield wiper also increases the comfort for the occupants, since the windshield therefore no longer has to be cleaned manually.According to a modified embodiment, it is provided that the windshield wiper has at least one windshield wiper receptacle, at least one windshield wiper linkage and at least one windshield wiper arm, wherein the at least one windshield wiper receptacle is connected to the windshield wiper linkage and wherein the windshield wiper linkage is connected to the windshield wiper arm. By separating the windscreen wiper receptacle, windscreen wiper linkage and windscreen wiper arm and their respective connection, the actuation of the windscreen wiper arm can be shifted into the periphery of the window. Thus, the visual limitation by the windshield wiper itself is minimized and the non-visual surface of the windshield is maximized. In this case, the windscreen wiper arm and windscreen wiper linkage can in particular also be of very delicate design, as a result of which visual restrictions can be further reduced. The split structure provides some modularity, which can reduce production costs. The flexibility also ensures freedom of design, since, for example, a re-adjustment or an upgrading of components is made possible. Various functions are assigned to the various windscreen wiper parts. The windscreen wiper arm ensures the cleaning of the window, the receptacle ensures the transmission of a drive torque or an actuation to the linkage, and the linkage ensures the implementation of a targeted movement sequence of the windscreen wiper arm.According to a modified embodiment, it is provided that the windscreen wiper arm extends completely over the windscreen, wherein in particular the windscreen wiper linkage extends at least partially over the windscreen. In particular in the case of mobile mobility tools or Senior Mobiles with large and curved front panes, a windscreen wiper arm running completely over the pane ensures uniform and complete cleaning. In particular, it is thus also ensured that the view through the pane is improved and thus the safety is increased. Thus, the risk of overlooking obstacles or traffic signs due to soiled pane areas is minimized. The windscreen wiper linkage running partially over the window distributes the actuation forces more uniformly to the windscreen wiper arm, which makes the mechanism more stable and longer-lived. It also protects the mechanism from overloading, since a stable base for the windscreen wiper arm is thus present.According to a modified embodiment, it is provided that the windscreen wiper arm can be actuated in a permanently perpendicular orientation on a circle segment in a lateral direction via the front windscreen. The lateral movement along a segment of a circle uniformly and efficiently covers the entire front pane. The vertical alignment ensures that the upper and lower regions, in particular the corner regions, of the front pane are also reached, which is often neglected in conventional systems. The vertical alignment also ensures a uniform force distribution on the wiper arm and on the windshield, as a result of which the wear of mechanics and wiper lips is reduced. The construction also minimizes the risk of the wiper arm being blocked or damaged by asymmetric loads. With the circular movement along the lateral axis, the requirements for the drive means are reduced because then in particular rotational drive means can be used which belong to the most common drive means and can be made very compact. In the vertical rest position, the windscreen wiper arm in particular also generates less air resistance than if the windscreen wiper arm were to be at a lateral angle to the vertical axis. As a result, the aerodynamics of the vehicle are improved.According to a modified embodiment, it is provided that the windshield wiper has two windshield wiper receptacles and wherein the windshield wiper linkage has two wiper rods of equal length and a substantially horizontal alignment rod, is configured in such a way that the wiper rods are mounted with their respective first end in one of the respective windshield wiper receptacles and are connected with their respective second end to one end of the alignment rod in each case, wherein the horizontal distance of the windshield wiper receptacles corresponds to the length of the alignment rod. Due to the uniform length of the wiper rods and the horizontal alignment rod, the movements of the wiper rods are perfectly synchronized. The forces for actuation can thus be transmitted uniformly from the two drives to the windscreen wiper arm. Due to the design with a horizontal alignment rod, the windscreen wiper arm is less susceptible to forces acting transversely to its vertical alignment. Thus, the windscreen wiper arm can be held in its vertical orientation when forces act transversely to its vertical orientation. In this case, a lever effect can be achieved via the horizontal alignment rod. The horizontal alignment rod also allows a compact construction that easily fits into the vehicle design without requiring much space.According to a modified embodiment, it is provided that the windscreen wiper linkage has at least one spring system, wherein the spring system generates a contact pressure of the windscreen wiper arm on the window. The spring system allows the windscreen wiper arm to lie flexibly on concave or convex disc shapes with a uniform contact pressure. The uniform contact minimizes the formation of wiping stripes and substantially improves cleaning performance. As a result of the constant adaptation of the pressure, the windscreen wiper arm is worn less strongly, which lengthens its service life. The spring system holds the windscreen wiper arm firmly on the window even under severe conditions such as heavy rain, snow or dirt. At the same time, the spring system also yields when an unoverspendable obstacle is present on the pane. This can be, for example, an ice layer on the pane. Instead of loading the drives in such a case by excessively high load torques, the spring system yields and slides over the obstacle. The service life of the drive components and of the windshield wiper parts is thus significantly increased. The spring system also absorbs minor movements and vibrations, which reduces the load on the mechanics and the drive.According to a modified embodiment, it is provided that the windscreen wiper arm has at least one wiper blade, made of at least partially elastic material. The elastic material optimally adapts to the contour of the pane, regardless of its shape or curvature. As a result, the constant contact pressure can be realized particularly easily.According to a modified embodiment, it is provided that the spring system generates the contact pressure via a bistable rotary joint. A bistable pivot joint is a mechanical joint which can change between two stable positions. These positions are the equilibrium positions in which the joint remains without additional force application. The transition between these positions takes place by an external force effect, wherein the joint in the described case is held in the two stable positions by a force of the spring system. An embodiment with a magnet system instead of a spring system is also conceivable. The two stable positions may be as follows. First, the working position of the windscreen wiper arm, i.e. the pressed-on state on the pane. Secondly, the maintenance position of the windscreen wiper arm, i.e. the inclined state of the windscreen wiper arm away from the window when it hangs in the air and both the window and the windscreen wiper arm can be maintained. The transition between the two positions can be overcome with a low muscle power of an operating person.According to a modified embodiment, it is provided that the front body has a headlight, in particular an LED headlight. A headlight is an essential component for illuminating the travel path and for increasing the visibility of a mobility aid. In particular, modern LED headlights can adapt the light cone of the headlights to the driving situation (e.g., cornering light, low beam). LED headlights offer the following advantages compared to conventional halogen or xenon headlights. LEDs generate a brighter and clearer light, which illuminates the travel path in an optimal manner. They also provide more precise and uniform illumination without dark spots. LEDs consume up to 80% less energy than conventional halogen lamps, which protects the energy storage, such as a battery, of the mobility aid and increases the range. They have an average lifetime of 15,000 to over 50,000 hours, making them far more durable than e.g. halogen lamps. LED headlights are smaller and lighter, which offers more freedom of design in the design of the mobility aid. LEDs are also more resistant to vibrations and shocks, making them ideal for mobility tools travelling on uneven terrain.According to a modified embodiment, it is provided that the front body has at least one, in particular two turn signal lights, in particular LED turn signal lights. Turn signal lights, also called turn signal indicators, are essential safety elements on drivable mobility tools. They serve for communication between road users, signal other road users a planned change of direction and contribute substantially to avoiding accidents. The clear communication with other road users is of particular importance in the case of moving mobility tools, which are often in mixed traffic situations with pedestrians, bicycles and motor vehicles. LEDs immediately reach their maximum brightness, which is advantageous particularly in the case of brake lights or turn signal lights. In particular, it is provided that the flasher lights are configured dynamically. Such flasher lights point in the intended direction of travel due to their lighting behavior. This increases the signal effect and realizes a particularly aesthetically appealing turn signal light. In particular, it is provided that the indicator lights can be operated intuitively via an actuating means on the steering devices. While the indicator lights are active, a noise signal can be provided in particular, which notifies the driver of the mobility aid of the active state of the indicator lights.According to a modified embodiment, it is provided that the front body has an outer front cladding means and an inner front cladding means embedded in the outer front cladding means, and at least one, in particular two, bracket means. The outer front cladding means provides a robust outer shell which protects the mobility aid from impacts and external influences. The inset interior front panel means enhances the stability of the body and absorbs additional loads, especially in frontal collisions. The separation into outer and inner front cladding means results in a modularity of the front body, which enables a separate design and exchangeability. The bracket means provide additional structural support to the front body at the height of the front window and thus ensure increased stability and resistance. The strap means can also be used in particular to fasten components such as handles, baskets, mirror structures or safety devices or to support devices such as the roof structure. However, the ironing means can also be used without any add-on components as a supporting retaining means during entry and exit. The bracket means can in particular also be used for fastening skirts or covers in order to protect the cabin from moisture, for example.According to a modified embodiment, it is provided that the pane has a rubber lip on the left and / or right side, wherein the rubber lip surrounds the pane on the left and / or right side. Rubbers are understood to mean the vulcanizates of natural and synthetic rubbers. Rubber remains flexible, even in the event of temperature fluctuations, weathering influences and UV radiation, and thus ensures a permanent seal. The rubber lip prevents water from penetrating the cabin via the edge of the pane and thus protects it from moisture. Rather, the rubber lip enables efficient discharge of rainwater, melt water, snow and dirt on the side of the window pane up to the part of the front body which is located below the window pane. In addition, the rubber lip protects the lateral edges of the pane from abrasion or contact with hard surfaces and articles. Cracks in the pane are thus avoided.According to a modified embodiment, it is provided that the cabin has a rear body and a rear structure on the rear side. The rear body protects sensitive components such as drive means, energy stores, wheel suspensions or electronic systems from weathering influences, dirt and damage. In addition, it ensures additional protection in rear-end collisions of other road users and thus protects the occupants from injuries. The rear body offers space for tail lights, brake lights and reflectors, which increase the visibility of the vehicle in road traffic. Backup cameras, sensors, or other technologies may be incorporated into the rear body to facilitate operation of the mobility implement. The rear structure can accommodate additional loads such as transport means, such as a trunk, trailer couplings, or other devices. The rear construction additionally enables the fastening of accessories such as baskets, carriers, holders for walking aids and the like. By means of a stable rear structure, additional loads can be introduced effectively into the rear body. It is conceivable, for example, for at least parts of the weight of the roof construction to be conducted on the rear construction loads and the weight of the roof construction to thus be conducted at least partially via the rear body to a rear wheel axle.According to a modified embodiment, it is provided that the rear structure has at least one, preferably two, rear vertical bow means. The vertical yoke means effectively deflect loads and forces downwardly, which increases the stability of the overall structure. The vertical yoke means act as load bearing means which absorb vibrations and loads and thus extend the life of the mobility aid. The vertical bow means provide fastening points for transport means such as luggage carriers, baskets, as well as for holders for walking aids, tail lights or reflectors. Cables or sensors can be guided through or along the vertical bracket means from the body of the hook to the roof structure in order to integrate technical devices such as backup cameras, lighting or sensors. The vertical bow means may also serve as an impact guard and absorb the energy in the event of an accident before the occupants of the cabin are injured. In conjunction with cross braces, the vertical bracket means can form a particularly stable frame structure.According to a modified embodiment, it is provided that the at least one rear vertical bow means has a main extension curve and two ends. The main extension curve of the vertical bow means gives it a truss-like function, so that tensile and compressive forces in the longitudinal or normal force direction, i.e. in the direction of the main extension curve, can be absorbed particularly well and transverse forces can be reduced.According to a modified embodiment, it is provided that the rear vertical bow means are spaced apart from one another by at least one, preferably two cross braces. Cross braces connect the vertical bracket means and improve the overall stability of the rear structure by enabling a uniform load distribution. The cross braces reduce, for example, the torsion forces acting on the vertical bow means. The cross braces also act as a stabilizer that minimizes vibrations and oscillations, which increases the comfort of the ride. The cross braces make it possible for the vertical bracket means to be made less massive, which reduces material costs. The cross braces also provide stable fixing points for safety-relevant elements such as tail lights, reflectors or backup cameras and provide fastening possibilities for transport means such as baskets and luggage carriers as well as for holders for walking aids or other payloads.According to a modified embodiment, it is provided that the spacing of the rear vertical bow means corresponds substantially to the cabin width. The adaptation of the vertical bow center distance to the cabin width ensures a wide and stable base of the rear structure, which reduces tilting moments of the mobility aid and increases driving safety. The vertical bow means form a frame which encloses the cabin in particular at the rear corners and offers additional protection in the event of collisions.According to a modified embodiment, it is provided that at least one of the rear vertical bow means has a holding means for holding a walking aid. The holding means is designed such that the walking aid can be easily latched and unlatched without requiring great force expenditure. Users who rely on walking can carry them with ease, thereby promoting their independence. The arrangement on the rear vertical bow means enables the external fastening of the walker without restricting the interior of the cabin. The walking aid is thus also in a readily accessible position, so that the user can easily reach it before, after or during getting in and out and can place it independently and remove it. The holding means can be arranged in particular at a height and position ergonomic for the user, so that the user can easily remove and place the walking aid. The holding means can be designed for different types of walking aids, such as walking sticks, rollerators, backs or other walking aids. The transport of other objects such as umbrellas or foldable chairs is also conceivable.According to a modified embodiment, it is provided that the rear body has at least one tail light and / or at least one stop light. Tail lights increase the visibility of the mobility aid in poor lighting conditions, such as twilight, night or fog. Brake lights signal other road users clearly and early that the mobility aid decelerates, whereby rear-end collisions can be avoided. The presence of rear lights and stop lights also contributes in principle to the fact that the mobility aid is also perceived in dense traffic or in poorly illuminated paths. The rear and stop lights can be designed in such a way that they are harmonically integrated into the rear body without disturbing the optics. In particular, the tail and / or stop lights are designed as LED tail and / or LED stop lights. In particular, modern LED rear and / or LED brake lights can adapt the light cone of the headlights to the driving situation. LED rear and / or LED stop lights offer the following advantages compared with conventional halogen or xenon headlights. LEDs generate a brighter and clearer light, which optimally illuminates the travel path in the reverse gear. They also provide more precise and uniform illumination without dark spots. LEDs consume up to 80% less energy than conventional halogen lamps, which protects the energy storage, such as a battery, of the mobility aid and increases the range. They have an average lifetime of 15,000 to over 50,000 hours, making them far more durable than e.g. halogen lamps. LED tail and / or brake lights are smaller and lighter, which offers more freedom of design in the construction of the mobility aid. LEDs are also more resistant to vibrations and shocks, making them ideal for mobility tools travelling on uneven terrain. In combination with other systems (e.g., backup cameras or acoustic alerts), tail lights improve orientation and safe maneuvering.According to a modified embodiment, it is provided that the bracket means each extend from a front cladding means, underneath the roof construction, along as far as the rear structure of the cabin, wherein the bracket means are each connected in particular to a respective one of the rear vertical bracket means. The course of the bow means, the course of the vertical bow means of the rear structure and the connection between these bow means together with the body parts and the substructure or frame structure form a protective frame which completely surrounds the mobility aid and protects the occupants of the cabin from external influences in the event of an accident. The connection to the rear vertical bow means also ensures in particular an improved stability of the rear region of the mobility aid. They also carry the weight of the roof construction, whereby a uniform load distribution is achieved. This reduces unwanted oscillations or vibrations, which increases the driving comfort. The bracket means can furthermore serve as a holder for additional equipment, in particular within the cabin, for example for interior lighting, handles, holding devices or luggage nets. The ironing means and their course also offer an ideal space for laying and protecting electrical lines or cables (e.g. for lighting or communication systems). The continuous strap means provides an aesthetically pleasing connection between the front and rear of the cabin. Additional components or modules (e.g. side panels or skirts, in particular weather protection components) may be attached to the ironing means.According to a modified embodiment, it is provided that the headlight is arranged in the inner front cladding means and wherein the indicator lights are arranged in the outer front cladding means. The embedding in the inner front cladding means protects the headlight better from external effects such as stone chipping, weather influences or mechanical damage. The turn signal lights in the outer front cladding means are positioned further outwards, which increases their visibility for other road users, in particular during turning processes.According to a modified embodiment, it is provided that the front pane is arranged so as to be framed laterally by the two rubber lips, at the top by the roof construction and at the bottom by the front body. The comprehensive framing keeps the front window stable and minimizes vibrations during travel. The framing protects the occupants in the event of accidents in that the front windshield cannot easily be released from its anchoring. The pane is thus held in place even in the event of damage, whereby the risk of chip injuries is minimized. The flush integration of the front pane into the roof construction and the front body also optimizes aerodynamics, which improves the energy efficiency of the mobility aid. Framing the pane also reduces the formation of moisture and condensation at the pane edges.According to a modified embodiment, it is provided that each bracket means has a laterally protruding mirror construction. Mirror structures on the ironing means allow the rider of the mobility aid to improve around the mobility aid. This ensures safe manoeuvring in particular during lane changes, reverse drives or tight turning maneuvers. Blind spots in the driver's field of view can thus be reduced and accidents with obstacles, other vehicles and, in particular, damage to persons can be avoided. By attaching to the bracket means, the mirror construction can be attached at a height and inclination adapted to the driver and adapted according to the requirements thereof. Thus, the ergonomy can be improved. The mirror structures may optionally be provided with additional functions such as integral flashers, defrost heaters, or electrical adjustment mechanisms.According to a modified embodiment, it is provided that the seat device of the cabin has a seat surface, and / or a back support device, and / or a headrest and / or one or two armrests and / or a seat belt.A seating surface provides a firm and secure seating posture that minimizes unwanted movements of the driver and thus improves control of the driver over the vehicle, which is important in particular in cornering, in sudden braking maneuvers and in uneven terrain. The seat surface can be designed in combination with the seat device to be height-adjustable, pivotable or tiltable in order to meet the individual requirements of the users. In particular, the seat surface can be configured to be foldable in order to allow access to the frame structure and / or the base plate. The seat surface can furthermore be equipped with additional features such as seat heating or ventilation, whereby comfort and functionality are increased. The seat surface is in particular designed such that it supports ergonomic seating and prevents back pain and fatigue symptoms. It advantageously comprises special materials or upholstery, which ensure a uniform pressure distribution, thus promoting blood circulation.The back support device ensures that the driver remains in a stable seating position, which improves control over the mobility aid. In particular, in the case of sudden braking maneuvers or journeys on uneven terrain, the driver is stabilized as a result. The back support device preferably adapts itself to the natural curvature of the spinal column and offers a comfortable and healthy seat position. Supporting the back and lumbar muscles reduces fatigue phenomena and stresses, especially during longer journeys. The back support device can in particular also have lateral cushions (e.g. in the form of contours). Such offer additional stability and prevent the driver from slipping laterally away. Advantageously, the back support devices are designed to be adjustable in their inclination angle, in their depth and in their height, so that the seat position can be adapted to the individual requirements of the driver. An adjustable back support device can be adapted to the height of the user's body, for example, in order to ensure optimum comfort. The back support device may have additional functionalities such as a massage function or a ventilation function in order to maximize comfort. The back support device is preferably configured to be foldable, thus allowing simplified access to a rear construction.A headrest provides protection for the neck and the spine of the driver, in particular during sudden braking, when driving on uneven terrain or when a rear-end collision occurs, i.e. during abrupt movements, by stabilizing the head, protecting against uncontrolled movements and minimizing the risk of a spin trauma. The headrest also relieves the neck and shoulder muscles during a normal journey, which prevents stresses and fatigue, in particular during long journeys with the mobility aid. In particular, the headrest is designed to be adjustable, such that the height and the inclination can be individually adjusted and can be adapted to the height of the driver's body in order to ensure optimum support. The headrest preferably has additional features such as loudspeakers, for example, whereby the comfort and the functionality of the headrest are increased.Armrests provide the driver with a shelf for the forearms, which relieves the muscles of the shoulders and the neck and prevents fatigue. The armrests additionally serve as a lateral delimitation and prevent the driver from sliding out of the seat, which is important above all in older persons or persons restricted in movement. The armrests provide the user with a stable support to which he can hold himself during getting in and out, as a result of which these operations are facilitated. Armrests thus offer older users more support and safety, which is important particularly with limited movability. By additionally assisting the arms, the driver can operate the steering wheel or the control unit more relaxed and more precisely. Hinged armrests make it possible to additionally facilitate entry by offering more freedom of movement. In particular, the armrests can be designed to be adjustable. In particular, it is provided that the armrests can be adjusted by a rotation mechanism on the underside of the armrests. This adjustability enables the user to adapt the height and / or inclination of the armrests to individual requirements, so that an optimum seating position with maximum comfort can be ensured. Armrests are preferably provided with additional functions, for example storage surfaces, storage compartments or storage recesses for smaller objects, such as remote controls or mobile telephones.A seat device comprising a seat belt offers additional protection against injuries in the event of an impact or sudden braking. The seatbelt prevents the user from being thrown out of the seat during a sudden braking maneuver, a collision or a vehicle tip-over. Also on rough roads or uneven terrain, the seat belt ensures that the driver remains stably in the seat. The belt holds the user securely in the correct seating position, as a result of which the risk of injuries is accordingly fundamentally reduced. In particular for persons with limited movability or weak muscles, the safety belt also offers an additional safety comfort in addition to the additional support. The seatbelt can preferably be individually adapted in length and position in order to ensure the best possible comfort and hold for different body sizes.According to a modified embodiment, it is provided that the seat device is arranged in the rear part of the cabin in the direction of travel and wherein the back support device is configured such that it almost completely closes the rear side of the cabin.The back support device, which almost completely closes the rear side of the cabin, protects the driver of the mobility aid from wind, rain, snow or dirt, which could penetrate from behind. The closed rear side also prevents the entry of draft air, which increases comfort, in particular at colder temperatures or during journeys at higher speeds. Noise from the rear portion of the mobility assist and ambient noise are also attenuated, which contributes to a smoother driving atmosphere. The closed device also ensures additional protection in the event of an accident. The area behind the closed back support device can be used as a protected stowage space for personal objects, bags or walking aids. The closed construction makes it possible to integrate additional functions such as integrated transport means, for example pockets, holders or compartments, into the back support device. It can be designed such that it optically harmonizes with the rear body and the mobility aid has an optically appealing appearance.According to a modified embodiment, it is provided that the back support device and / or the seat surface comprise a spring system. A spring system should in principle initially be understood to mean all systems which have at least one spring element. In particular, this also includes combined spring damper systems. In the case of the back support device, a rotatory spring system on a rotational joint of the back support device is to be understood in particular. In the case of the seat surface, on the other hand, a linear spring system is to be understood here at least in the vertical direction. However, further spring systems in the horizontal direction are also conceivable. Vibrations due to uneven running surfaces, curbs or impact holes can be compensated for effectively by the spring system, which reduces the load on the body of the user. In particular, excessive loads on the spinal column and on the hip and knee joints are avoided. The suspension system also helps the mobility operator maintain the balance during travel. The spring system can preferably be adapted both manually and automatically to different driving conditions and to the driver.According to a modified embodiment, it is provided that the back support device is designed such that it can be displaced forwards and backwards in the direction of travel. As a result, the back support device can be adapted individually to the body dimensions of the driver in an optimum manner. The displacement of the back support device also allows to vary the distance to the steering device and the leg room to the front body, whereby users can optimize their arm and leg position. The ability to displace the back support device rearwardly provides additional freedom of movement within the cabin. This facilitates entry and exit for persons with limited mobility. By displacing the back support forwards, additional stowage space can be created behind the cabin, for example for purchases, personal objects or an additional walking aid.According to a modified embodiment, it is provided that the back support device has a transport means on its side facing away from the direction of travel, wherein the transport means is configured in particular to be closable. A means of transportation on the back support provides a convenient way of safely and conveniently carrying personal items, purchases, clothes or medicines. A transport means designed to be closable protects the contents from rain, snow and dirt and thus ensures reliable storage even in poor weather conditions. A transport means which is designed to be lockable in addition protects the content from theft or unauthorized access, which is particularly advantageous in public areas or when parking the vehicle. This anti-theft protection is of particular importance in particular for seniors. The positioning of the transport means on the rear side of the back support device makes efficient use of the space available there without restricting the freedom of movement or the comfort of the user in the cabin. Preferably, the transport means is integrated in the back support device or fastened thereto. This is particularly advantageous in combination with a foldable back support device, since access to the transport means within the cabin is thus made possible by folding over the back support device. When accessing the transport means from the rear side of the mobility aid, the user can hold himself on the vertical bow means of the rear construction. Depending on the configuration, the transport means can also be configured as a removable backpack, removable carrying bag or as a removable shopping trolley, which increases the flexibility.According to a modified embodiment, it is provided that the head restraint is adjustable at least in its height. A headrest provides protection for the neck and the spine of the driver, in particular during sudden braking, when driving on uneven terrain or when a rear-end collision occurs, i.e. during abrupt movements, by stabilizing the head, protecting against uncontrolled movements and minimizing the risk of a spin trauma. The headrest also relieves the neck and shoulder muscles during a normal journey, which prevents stresses and fatigue, in particular during long journeys with the mobility aid. The adjustability of the height of the headrest is of particular importance here, since it effectively protects the occupants only if it is set at the correct height and is adapted to the height of the driver's body.According to a modified embodiment, it is provided that the at least one armrest is adjustable at least in its angular position, in particular by a rotation mechanism. Armrests provide the driver with a shelf for the forearms, which relieves the muscles of the shoulders and the neck and prevents fatigue. The armrests additionally serve as a lateral delimitation and prevent the driver from sliding out of the seat, which is important above all in older persons or persons restricted in movement. The armrests provide the user with a stable support to which he can hold himself during getting in and out, as a result of which these operations are facilitated. Armrests thus offer older users more support and safety, which is important particularly with limited movability. By additionally assisting the arms, the driver can operate the steering wheel or the control unit more relaxed and more precisely. Hinged armrests make it possible to additionally facilitate entry by offering more freedom of movement. Armrests are particularly advantageous which are designed to be adjustable in their angle of inclination. The armrests can thus be adapted to the individual requirements of the driver. In particular, it is provided that the armrests can be adjusted by a rotation mechanism on the underside of the armrests. The axis of rotation is preferably arranged parallel to the main direction of extension of the armrest. The driver can rest his arm on the armrest, can be supported with his thumb on an upper side edge of the armrest and can actuate the rotation mechanism on the underside of the armrest with at least one of the other fingers, i.e. his index finger, middle finger, ring finger or little finger. This allows the driver to adjust the inclination of the armrests with a simple hand movement during travel, so that an optimum rest position of the forearms can be ensured with maximum comfort.According to a modified embodiment, it is provided that the mobile mobility aid has at least one, preferably three or four wheels. Wheels allow the movement of the mobility aid on various planar and, however, also partly uneven substrates, such as, for example, asphalt floors, concrete floors, metal floors, gravel floors, stone pavement floors, rock floors, ramping threads, lawn surfaces, wood floors, sand floors, plastic floors. Wheels can also be adapted to various substrates in particular by profile, rubber mixture, size and width and tire pressure. With three wheels, the mobility aid initially stabilizes itself with respect to a single wheel or two wheel. Three wheels also allow only a small turning circle as opposed to a four wheel, making the vehicle easily maneuverable especially in narrow spaces such as homes, stores, pedestrian paths, or elevators. A three-wheel mobility aid is usually lighter than a four-wheel model, making it easier to transport and load. Tri-wheeled models often have a more sporting and compact external appearance that modem users are responding. The lower material and manufacturing complexity often results in lower costs of purchase and reduced maintenance effort. Tricycles are well suited for planar surfaces and moderately rough terrain such as fixed paths and urban areas. Four wheels, on the other hand, offer a higher level of tilting safety, especially in turns or when travelling over uneven terrain, for example on ballast paths, lawn surfaces or headstone plasters, but in particular also on unfixed terrain. The uniform weight distribution in a four-wheel drive ensures stable driving dynamics and a more reliable driving feel. Four-wheel models usually also offer better suspension and smoother handling, which is advantageous in particular on longer journeys or at higher speeds. Such mobility tools are usually more robust in design and can carry heavier loads, whether the user himself or additional luggage. The additional stability allows for a more secure integration of functions such as higher seating positions, which is particularly very popular with older drivers, large batteries for a greater range or heavy accessories or luggage.According to a modified embodiment, it is provided that the mobile mobility aid has at least one, preferably two, wheel axles. Two wheel axles allow better distribution of vehicle and user weight, making the mobility aid more resilient. The mobility aid can thus carry greater overall loads, such as additional persons, luggage or accessories, without impairing stability. Two wheel axles make it possible to use different wheel sizes on these two. Particularly large wheels can thus be used for the drive on one of the axles and smaller wheels for better handling on the other axle. With three wheels, the mobility aid initially stabilizes itself with respect to a single wheel or two wheel. Three wheels also allow only a small turning circle as opposed to a four wheel, making the vehicle easily maneuverable especially in narrow spaces such as homes, stores, pedestrian paths, or elevators. A three-wheel mobility aid is usually lighter than a four-wheel model, making it easier to transport and load. Tri-wheeled models often provide a more sporting and compact external appearance that modern users are responding. The lower material and manufacturing complexity often results in lower costs of purchase and reduced maintenance effort. Tricycles are well suited for planar surfaces and moderately rough terrain such as fixed paths and urban areas. Four wheels, on the other hand, offer a higher level of tilting safety, especially in turns or when travelling over uneven terrain, for example on ballast paths, lawn surfaces or headstone plasters, but in particular also on unfixed terrain. The uniform weight distribution in a four-wheel drive ensures stable driving dynamics and a more reliable driving feel. Four-wheel models usually also offer better suspension and smoother handling, which is advantageous in particular on longer journeys or at higher speeds. Such mobility tools are usually more robust in design and can carry heavier loads, whether the user himself or additional luggage. The additional stability allows for a more secure integration of functions such as higher seating positions, which is particularly very popular with older drivers, large batteries for a greater range or heavy accessories or luggage.According to a modified embodiment, it is provided that the first wheel axis corresponds to a front wheel axis and the second wheel axis corresponds to a rear wheel axis, wherein two wheels, the three or four wheels, are arranged on the rear wheel axis and one or two wheels, the three or four wheels, are arranged on the front wheel axis. Two wheel axles allow better distribution of vehicle and user weight, making the mobility aid more resilient. The mobility aid can thus carry greater overall loads, such as additional persons, luggage or accessories, without impairing stability. Two wheel axles make it possible to use different wheel sizes on these two. Particularly large wheels can thus be used for the drive on one of the axles and smaller wheels for better handling on the other axle. With three wheels, the mobility aid initially stabilizes itself with respect to a single wheel or two wheel. Three wheels also allow only a small turning circle as opposed to a four wheel, making the vehicle easily maneuverable especially in narrow spaces such as homes, stores, pedestrian paths, or elevators.

Such mobility tools are usually more robust in design and can carry heavier loads, whether the user himself or additional luggage. The additional stability allows for a more secure integration of functions such as higher seating positions, which is particularly very popular with older drivers, large batteries for a greater range or heavy accessories or luggage.According to a modified embodiment, it is provided that the steering device is operatively connected, in particular mechanically, to the front wheel axle. Front axle steering is the standard for most vehicles, making operation more intuitive for users. In comparison, rear axle steering requires uneasy steering movements that are more difficult to control for inexperienced drivers. In a front axle steering system, the vehicle remains more stable when cornering, since the front wheels specify the direction and the rear wheels follow. Rear axle steering can result in oversteering, which is particularly dangerous at high speeds. The front axle steering is thus particularly suitable for drivers with limited fine motor capabilities. Moreover, a rear axle steering system requires more complex joints and mechanics, since it is often claimed in addition to the drive. The front axle steering is simpler and longer-lived.In a mechanical operative connection, the user feels the resistance and the movement of the wheels directly via the steering device, which gives a better feeling for the road conditions. This type of connection also allows direct transmission of the user's steering inputs to the wheel axle, which ensures precise and reliable control. Compared to electronic or hydraulic systems, a mechanical connection is less susceptible to faults, since no complex electronic components or external energy sources are required. Mechanical systems are also usually longer-lived and easier to maintain, since they are less susceptible to failures due to electrical defects or leaks. Thus, the control of the mobility aid via the mechanical connection remains fully functional even in the event of a failure of the power supply or other electronic components. Mechanical systems are less expensive to manufacture and integrate into the mobility tool and easier to maintain. They are also less susceptible to influences such as moisture, cold or heat compared to electronic systems. However, the mechanical operative connection can be supported by electronic or hydraulic systems.According to a modified embodiment, it is provided that the frame structure has two rollers on the side facing away from the direction of travel. Such additional rollers arranged in the rear can perform various tasks. It is thus conceivable that the mobility aid can be pushed more easily by the additional rollers in the rear area of the mobility aid if it is not actively driven, for example during maneuvering, stowage or parking. It may also be necessary to maneuver the mobility aid if the mobility aid fails, because, for example, the battery is completely empty. The mobility aid can then be tilted like a roller case and pulled on the rollers, which is advantageous in particular when overcoming short distances. By means of the rollers on the rear side, the mobility aid can also be tilted when loading into a vehicle and moved on the rollers. When parking or pulling, the framework is protected from direct ground contact by the additional rollers, which extends the life of the mobility aid. The rollers are also helpful if the mobility aid has to be tilted for repairs in order to enable access to the underside, then the rollers offer a stable bearing surface and prevent contact of the body with the ground. In particular, the rollers can be designed such that they are folded in or concealed when not in use, as a result of which the optics and aerodynamics are not impaired.According to a modified embodiment, it is provided that the two rollers are arranged spaced apart beyond the wheels in the direction facing away from the direction of travel via support bolts. Due to this spacing, the rollers protrude beyond the wheels. If the mobility aid is tilted, the rear wheels will accordingly also be detached from the ground. Thus, the rollers can be used advantageously, in particular during the maintenance of the rear tires.According to a modified embodiment, it is provided that the mobility aid has at least one braking device and wherein the steering device has a brake actuation mechanism for actuating the at least one braking device. The braking device on the mobility aid ensures a controlled speed and prevents undesired acceleration on descending routes. The brake device can be designed as a mechanical brake, in particular as a drum or disc brake. Such brake devices are particularly reliable and low-maintenance. However, electronic brake devices or a combination of mechanical and electronic brake devices are also conceivable. Electronic brake devices are understood in particular to mean devices which use powerful electric motors from the drive unit of the mobility aid in a recuperation mode. During the braking process, the resistance in the electric motor is accordingly used to reduce the speed of the mobility aid and at the same time to feed energy back into the energy store of the mobility aid. This allows wear on the mechanical brakes to be reduced and the range of the mobility aid to be increased. In particular, this recuperation mechanism can also be integrated into a so-called one-pedal driving operation. One-pedal driving operation is understood to mean that the mobility aid is accelerated by an actuator, such as a rotary throttle grip on the steering device or an accelerator pedal, when the actuation is active, and the mobility aid is automatically braked in recuperation operation when the actuation is absent. As a result, the mechanical brakes need only be used in support or emergency situations. The placement of the brake actuation mechanism on the steering device facilitates the use of the same for the rider and enables an intuitive operation that should be known to the rider of bicycle and / or motorcycle riding. It is advantageous here that the hands do not have to be released from the steering device.According to a modified embodiment, it is provided that the brake actuation mechanism has a parking or parking function. A parking and / or parking function allows the user to stabilize the mobility aid during parking and to protect it from unintentional rolling away. The locking or parking function is preferably configured such that it has a spring pin. A spring pin is understood to be a cylindrical component which has a restoring spring. With such a spring pin, the brake lever can be fixed in an operating state by actively operating the spring pin. By actuating the brake lever again, the spring pin quickens back into its initial position and thus unlocks the locking or parking function. This makes it possible to realize a very cost-effective, easy-to-operate and low-maintenance parking brake.According to a modified embodiment, it is provided that the seat device has a seat detection device, in particular designed as a weight sensor. The seat detection device can detect when a person has put a seat on the seat device and when this person leaves the seat device again. Based on this information, additional security facilities of the mobility aid can be realized. It is thus conceivable, for example, for the mobility aid to be activated or deactivated depending on the detection in order to prevent uncontrolled driving off. The seat detection device is preferably designed such that a fall detection device can be coupled therewith. In particular, the seat detection device is designed as a weight sensor. Based on the detected weight, settings of spring systems and / or seat position may be automatically adjusted to maximize comfort. If no weight is detected on the seat, the mobility device can automatically switch to the standby mode in order to save energy. If the sensor detects an abrupt weight displacement or the sudden leaving of the seat, the mobility aid can automatically stop in order to prevent accidents. Sudden unloading of the seat may trigger a warning signal to alert potential fall hazards. The combination of the seat detection device and the seat belt sensors ensures that the mobility aid can be activated only when the user is correctly fastened.According to a modified embodiment, it is provided that the mobility aid has an alerting device. The alerting device may be configured, for example, to be triggered when the mobility tool is moved or actuated unauthorized, thereby quenching potential thieves. An alerting is conceivable, for example, when approaching the mobility aid, when touching / moving the mobility aid, or when entering the cabin of the mobility aid. However, other scenarios are also conceivable. However, the alerting device can also alert the driver himself to potential hazards such as obstacles, imminent collisions or unusual movements such as the tipping over of the mobility aid, but also to technical problems of the mobility aid. It can also display to the driver the position of the mobility aid in a parking facility. The alerting device can automatically trigger an alarm and request assistance in emergency situations, such as in the event of a fall of the driver. The alarming device can rely on audio and visual alarming means.According to a modified embodiment, it is provided that the mobility aid has a radio device, in particular an emergency radio device. Via a radio device, the driver can communicate with or contact emergency services or relatives. The radio device can be actuated manually or automatically. In particular in emergency situations, such as an accident, a fall or a medical emergency, contact with emergency services can be quickly made via the emergency radio device, whereby the reaction time is minimized. In particular, the radio device has a GPS module which transmits the position of the mobility aid in an emergency situation. Communication of the radio device with traffic guidance systems is likewise conceivable.According to a modified embodiment, it is provided that the mobility aid has a digital tachometer. Information such as the speed of the mobility aid, the mileage, the battery status, the time, the temperature or various warning messages can be displayed in a space-saving and cost-effective manner on a digital tachometer. The display can be adapted to the individual requirements of each driver. Integrated lighting ensures that the display is well visible even at night or in dark environments.According to a modified embodiment, it is provided that the mobility aid has at least one camera, wherein the one camera is in particular configured such that the cabin is monitored with driver. The camera may be used to monitor the state of the driver. Complex situations can be analyzed with AI-assisted image processing. For example, it may be determined if there are signs of discomfort when the driver has become conscious, when the driver does not watch on the road, when the driver is distracted, whether there are signs of tiredness, whether the driver is fastened, or whether there is a danger near the cabin. In the event of an emergency, the camera may automatically send images or video to an emergency service or to relatives, thereby enabling a quick response and improved diagnosis. In such cases, the alerting device and / or radio device can also be automatically activated and an emergency service contacted. The camera can also be used to identify the driver and to make personalized settings such as those of the seat device. The camera can also record activities in the cabin in the deactivated state of the vehicle and serves as a restraint for potential thefts or vandalism.According to a modified embodiment, it is provided that the mobility aid has a fall detection device, wherein a fall of a driver is detectable by the fall detection device, in particular by monitoring the camera and / or the seat detection device and / or the tachometer. The fall detection device reliably recognizes when a driver falls from the mobility aid, for which purpose a plurality of sensors and data sources are preferably read out and the information is jointly processed in order to ensure the highest possible probability during the fall recognition. The camera can immediately recognize when the driver has fallen with the aid of image recognition and AI software. The seat detection device recognizes when the seat is no longer occupied by a driver, which can be a first indicator of a fall. If at the same time a strong acceleration also occurs due to an impact, this information can be passed on to the fall detection device via the digital tacho. If a fall is reliably detected, immediate measures can be initiated immediately. The drive can be switched off, warning lights switched on and radio, brake and alarm devices activated.According to a modified embodiment, it is provided that the fall detection device activates the braking device and / or alarm device and / or radio device upon detection of a fall of a driver. By activating the brake device, the mobility aid is stopped and prevented from continuing to travel, and rolling away on descending terrain can also be avoided. When the alerting function is activated, passers are alerted to the fall and animated for assistance. Emergency services and relatives are informed with the aid of the radio device.According to a modified embodiment, it is provided that the mobility aid has a loudspeaker device and / or a USB charging device. The USB charging device can be used to charge mini-electronic devices such as smartphones or smart watches. Navigation instructions or music can be played from a navigation device or smartphone via the loudspeaker device, and telephone calls can be carried.Furthermore, a removable skirt for a drivable mobility aid described above is proposed.Brief Description of the DrawingsA mobility aid is explained in more detail below with reference to the attached drawings using preferred exemplary embodiments.

The cabin has a frame structure 12 on the underside 3 with a floor plate 11 lying above it, which completely encloses the cabin 2 of the mobility aid 1 on the underside 3. The framework 12 gives the mobility aid 1 its necessary structural stability with a comparatively low weight. At the same time, it ensures that the loads of the mobility aid 1 are efficiently introduced into the wheel axles of the mobility aid 1. The floor panel 11 above it acts as a base for the superstructures adjoining it above it, such as for example the front and rear body 23, 32, 33, 46 and the seat device 10, FIGS. 5-8 and 11 and 12 show that the floor panel 11 additionally has a profiled foot rest 13 with a structured surface in the front region of the cabin 2. The structured surface is configured in such a way that an increased stability against undesired slipping off is ensured and water and dirt accumulating on the foot rest 13 is effectively discharged via the side edges of the foot rest 13.In both exemplary embodiments, the frame structure 12 has a cup-shaped receiving means 14 for receiving a foot section of a walking aid. The receiving means 14 is a cup-shaped metal vessel 14 fastened to the frame structure 12 via a cantilever arm for receiving the rubber foot of a bridge, a bridge stock or a walking stock. However, fastenings to the floor panel 11 or other body components are also conceivable. The cup-shaped metal vessel 14 can enclose the foot section of the walking aid in particular to such an extent that the walking aid cannot be sheared off from its fastening or anchoring before unintentional slipping due to contact by persons or objects. Moreover, the cup-shaped metal vessel 14 protects the rider from soiling his clothing when entering the cabin 2 of the mobility aid 1 upon contact with the foot portion of the walker.It can be seen in FIGS. 5-8 and 11 and 12 that the cabin 2 can have two lateral entry edges, via which the entry into the mobility aid 1 is facilitated. Preferably, a lateral protrusion 15 is provided on one side or on both sides of the cabin 2 at the lateral entry edge, which protrusion facilitates entry and exit into or from the cabin 2 of the mobility aid 1 as an additional step.As is disclosed in particular in FIGS. 5-9, the upper side 5 of the cabin 2 is completely surrounded by a flat roof construction 16 in the form of a double-dome-shaped plastic roof 17. This protects the occupants from external environmental influences such as rain, snow, falling objects and direct solar radiation. The dome-shaped configuration 17 particularly promotes the drainage of rainwater and dirt that accumulates on the roof structure 16. It can be seen in FIGS. 1-5 and 9 that at least the left and right sides, but preferably also the rear side of the roof construction 16, have an outer edge with a roof construction edge lip 18, that is to say a plastic lip 18, which forms a discharge channel 19 between the roof construction 16 and edge lip 18 with the plastic roof which is embodied in one piece itself. With the aid of this drainage channel 19 which forms between the roof construction 16 and the roof construction edge lips 18 and which can be seen in particular in FIGS. 1, 2 and 9, it is possible to prevent splash water from passing from the roof into the cabin 2 and prevent accumulated water and / or dirt from flowing away in an uncontrolled manner.In accordance with a preferred embodiment, FIGS. 2, 4, 6, 8 and 12 disclose a mobile mobility aid 1 having three removable skirts 20, wherein a first removable, flexible and at least partially transparent skirt 20 closes the left side 7 of the cabin 2 in an upper third, based on the total height of the cabin 2, in the vertical direction, starting from the roof construction 16. Moreover, a second removable flexible and at least partially transparent skirt 20 closes the right side 8 of the cabin 2 in an upper third, with respect to the total height of the cabin 2, descending from the roof structure 16 in the vertical direction. Finally, a third removable, flexible and at least partially transparent skirt 20 closes the rear side 6 of the cabin 2 in an upper third, based on the total height of the cabin 2, starting from the roof construction 16 in the vertical direction up to the upper edge of the back support device 40. Skirts 20 which are configured shorter or longer can also be provided, so that, depending on requirements and environmental conditions, only just 1 / 5 or up to 4 / 5 of the respective side is covered by the skirt 20.In Figures 2, 4, 6, 8 and 12 it is shown that the two lateral removable skirts 20 are connected to zippers on ironing means 34 immediately below the roof construction outer edges as well as behind the front pane 22. This ensures a virtually gapless transition between the roof construction 16 or the front pane 22 and the lateral skirts 20 and prevents environmental influences such as rainwater, snow or dirt from entering. The third back removable skirt 20 is secured by a zipper to cross braces of vertical bracket means 37 of the rear structure 36, as shown in Figs. 4, 6 and 8. The connection between the skirt 20 and the roof construction 16 via the bow means 34 and cross braces located just below the roof construction 16 can also be designed in such a way that a direct connection of the roof construction 16 and the skirt 20 is provided, for example starting from the outer edge of the roof construction 16. Other releasable connections such as hooks, clips, pushbuttons, magnets, hook-and-loop connections or screws are also conceivable, wherein the configuration with slide fasteners 21, in particular watertight slide fasteners which have been welded after sewing in, is particularly preferred. In particular, the skirts 20 can also be designed such that the lateral skirts 20 and the rear skirt 20 can be connected at their adjoining outer edges, i.e. along the vertical bracket means 37 of the rear structure 36, in particular to corresponding zippers. Alternatively, the skirts 20 may also be directly attached to the vertical bracket means 37 of the rear structure 36. The skirts 20 are preferably designed to be resistant in such a way that they can fully absorb the weight of the driver in the event of a lateral force effect, for example caused by a collision or cornering, and can thus prevent the driver from falling out of the cabin 2.All three skirts 20 can be made of an at least partially flexible material, as in the embodiment shown in FIG. 11. As a result, the skirts 20 can be rolled in and temporarily fastened to the bracket means 34 or the roof construction 16 with a connecting means 21, such as a plug-in buckle 21, in the rolled-in state. FIG. 11 shows a corresponding exemplary embodiment with rolled-in skirts 20 and plug buckles 21 in conjunction with tensionable straps. Thus, the apron 20 can be quickly and securely removed and re-installed, so that the driver can change between an open and a closed state without having to remove the aprons 20 completely from the mobility aid 1.In the exemplary embodiments according to FIGS. 1, 2, 11 and 12, the front side 4 of the cabin 2 has a front window 22 which is convexly shaped in the horizontal and in the vertical, and a front body 23 with a windshield wiper 24. The front pane 22 is framed laterally by two rubber lips 35 that can be mounted on the side edges of the front pane and, at the upper edge, is contiguous seamlessly with a receiving region of the roof construction 16. The front body 23, 32, 33 is joined immediately below the front window 22, and is divided into an outer front body part 32 which extends in an H-shape in a front view and an inner front body part 33 which is embedded in the outer front body part 32 in such a way that it fills the U-shaped region between the upper legs of the H-shaped outer body part 32. On the upper legs of the outer body part 32, a flasher light 31 is arranged laterally in each case. Centrally in the inner front body part 33, a circular combination light of front headlight 30 and high beam is let in, as is disclosed in FIGS. 1, 2, 11 and 12.Attached to the upper ends of the outer front body panel 32 are the bracket means 34 extending below the front window edges which provide additional stability to the front window 22 and roof structure 16.FIGS. 1, 2, 11 and 12 show the wiper 24 having two wiper receivers 25 disposed in a central portion of the inner front body part 33. A windscreen wiper linkage 26, consisting of two wiper rods 28 and an alignment rod 29, extends from the windscreen wiper receptacles 25 in the direction of the windscreen 22, the windscreen wiper linkage 26 extending beyond the inner front body part 33 as far as approximately the center of the windscreen 22 in its vertical extension. Thus, the wiper arm 27 which is fixed to the wiper linkage 26 at the center extends substantially over the entire height of the windshield 22, with portions being omitted in the upper and lower parts of the windshield 22. When the windshield wiper 24 shown is actuated, the fastening point between the windshield wiper arm 27 and the linkage 26 moves over the windshield 22 on a segment of a circle in the lateral direction. As a result, the front pane 22 is cleaned uniformly and efficiently in a central quasi-square region, except for small edge regions along the outer edges of the front panes.FIGS. 11 and 12 each disclose a mirror construction fastened to the transition between the outer front body part 32, front pane 22 and bracket means 34, which mirror construction is designed as a side mirror with a flexible cantilever arm. The flexible cantilever enables the mirrors to be freely adjusted and individually adjusted in their angular positions to the driver.FIGS. 3 and 4 show exemplary embodiments of the mobile mobility aid 1 in which the cabin 2 has a rear body 46 and a rear structure 36 on the rear side 6. In the exemplary embodiments shown, the rear structure 36 consists of two metal rods 37 which are mounted on the rear body 46 and run substantially vertically and delimit the cabin 2 on the rear side 6. These vertical bow means 37 are connected to two welded cross braces, which are likewise designed as metal rods, in the region below the roof construction 16. One of the vertical bow means 37 has a holding means 38 for a walking aid. The holding means 38 is arranged on that side of the mobility aid 1 on which the receiving means 14 is also fastened. In the exemplary embodiments shown, it is the right side of the mobility aid 1 looking in the direction of travel. The holding means 38 is configured in such a way that a bridge, a bridge stock or a walking stock with a cylindrical shank region can be inserted into the holding means 38 from above in an angular position of approximately 45° perpendicular to a horizontal and then pressed in. In principle, all orientation angles of the holding means for the walking aid are conceivable. In particular, angles of 0°, which corresponds to the horizontal, up to 90°, which corresponds to a vertical, are conceivable. However, angles between 30° and 60° to a horizontal are preferred.The chopping body 46 according to the exemplary embodiments from FIGS. 3 and 4 has two lateral rear lights 47 and a centrally arranged stop light 48. The tail lamps 47 also have integrated flasher lamps 31 which switch simultaneously with the front flasher lamps 31. The stop light 48 is configured in both exemplary embodiments as an elongate, horizontally running stop light strip 48.FIGS. 5-8 and 11 and 12 show various embodiments, all of which have a seat device 10 in the rear part of the cabin 2, which have a seat surface 39, a back support device 40, a headrest 41, two armrests 42 and a seat belt and almost completely closes the rear side 6 of the cabin 2 with respect to the environment. The seat device 10 is configured here in accordance with a vehicle seat. The seat 39 is an approximately cuboidal padding provided with a fabric covering, which padding is arranged on a rail structure. Mounted on the rail structure is the support of the back support 40. Thus, the padding of the back support device 40, which is likewise provided with a fabric covering, is designed to be displaceable forwards and backwards in the direction of travel. Furthermore, the back support 40 can be angularly inclined at its mounting on the rail structure. The back support device 40 can be folded forwards in this case completely into the horizontal. Conversely, the angle of inclination relative to the vertical is limited to less than 45°. The back support device 40 can thus be adapted to the individual comfort requirements of the driver.The headrest 41 on the back support device 40 is a substantially square padding which is introduced into the upper side of the back support device 40 via two metal rods and is designed to be adjustable in its height in a stepwise manner. The back support device 40 and the headrest 41 protect the head and the spinal column of the driver from injuries in the event of a collision and strong accelerations.Furthermore, FIGS. 5-8 and 11-12 show the two armrests 42 which are connected laterally on the back support device 40 by means of a pivot joint. They can be adjusted in their inclination angle on their underside by means of a rotation mechanism and adapted to the individual requirements of the driver. The armrests 42 serve the users as a relief for the arms, as a getting-in and getting-out aid and as an additional limitation against lateral dropping out of the cabin 2.The seat device 10 additionally has a seat belt arranged in the holder of the back support device 40. Thus, a fall of the driver out of the cabin 2 in the event of a collision or in the event of strong accelerations of the mobility aid, such as, for example, by abrupt steering or acceleration maneuvers, can be avoided.The back support device 40 has a transport means 43 on its rear side, i.e. on the side facing away from the direction of travel. The transport means 43 is visible in FIGS. 3 and 4 and in FIGS. 5-8 and is designed as a substantially square closable case 43 consisting of a plastic shell, which case is arranged centrally on the back support device 40. The transport means 43 can be used to transport or store additional personal items, purchases, clothing or medicaments. The transport means 43 protects the contents in particular from unauthorized access and from poor weather conditions. In the exemplary embodiment, the transport means 43 is firmly connected to the back support device 40. However, alternative embodiments of the transport means 43 are also conceivable, in which case the transport means 43 can be removable and transported, for example in the form of a backpack or trolley.All the exemplary embodiments shown in FIGS. 1-12 are designed as trikes, i.e. have three wheels 44, one on the front axle and two on the rear axle. As a result of this configuration, the mobility aid 1 is particularly wasteful and has a lower weight than a four-wheeled embodiment. The wheels 44 are designed as air-filled profiled rubber tires on metal rims and are therefore suitable for various planar and, however, also partly uneven substrates, such as asphalt floors, concrete floors, metal floors, gravel floors, stone pavement floors, rock floors, ramping threads, lawn surfaces, wood floors, sand floors, plastic floors. All three wheels 44 have a wheel house, which serves in particular as a splash guard. Here, the wheels 44 of the rear axle are housed in a wheel arch which is integrated into the rear body 46. On the other hand, the front wheel 44 is covered by a wheel arch which is formed separately from the front body 23 and is arranged in the region between the lower legs of the H-shaped outer front body part 32.Further, FIGS. 5, 6, and 12 disclose a brake device disposed on the front wheel 44. In the exemplary embodiments, this is designed as a disc brake and is actuated via a brake actuation mechanism designed as a brake lever arranged on the steering device 10.The steering device 10 mentioned is illustrated in FIGS. 5-8 and 11-12 and is configured in a manner comparable to a two-wheeler, such as a motorcycle or bicycle, as a steering rod having two laterally arranged handles. The handle arranged on the right in the direction of travel is designed as a rotary throttle handle. In the exemplary embodiments, both handles have brake levers, wherein the brake lever arranged on the left in the direction of travel has a locking function. After the brake lever is operated, a cylindrical spring pin arranged below the brake lever can be inserted into a recess of the brake lever. If the brake lever is subsequently released, a force-fit connection is produced between the spring pin and the brake lever, whereby the latter is mechanically fixed in the operating state. By actuating the brake lever again, the force-locking part of the connection can be released, so that the spring mechanism of the spring pin conveys it out of the recess of the brake lever and thus automatically releases the fixing of the brake lever.As can be seen in FIGS. 3, 4 and 10, and indicated in FIGS. 5-8, the mobile mobility aid 1 has, in the rear region below the rear body 46 and beyond the wheels 44, two rollers 45 which are spaced apart from the mobility aid 1 as plastic rollers by supporting bolts in such a way that they make ground contact when the vehicle is tilted to the rear. The rollers 45 can thus serve as additional protection against tilting over. In addition, they facilitate stowage and parking of the mobility aid 1 if it is not actively driven. The mobility aid 1 can thus be tilted on in a manner comparable to a roller case and pulled or pushed over the rollers 45. The mobility aid 1 can thus be moved with a small amount of force.List of reference characters1 Mobility aid 2 Cabin 3 Underside 4 Front side 5 Upper side 6 Rear side 7 Left side 8 Right side 9 Steering device 10 Seat device 11 Floor plate 12 Frame structure 13 Foot rest 14 Receiving means 15 Lateral projection 16 Roof structure 17 Dome-shaped region 18 Roof structure edge lip 19 Outlet channel 20 Removable skirt 21 Connecting means 22 Front window 23 Front body 24 Windscreen wiper 25 Windscreen wiper receptacle 26 Windscreen wiper linkage 27 Windscreen wiper arm 28 Wiper rods 29 Alignment rod 30 Headlight 31 Indicator light 32 Outer front cladding means 33 Inner front cladding means 34 Bracket means 35 Rubber lip 36 Rear construction 37 Vertical bracket means 38 Holding means 39 Seat surface 40 Backrest device 41 Headrest 42 Armrest 43 Lockable transport means 44 Wheel 45 Roller 46 Rear body 47 Rear light 48 Brake light
