Description

Systems for moving passengers with mobility impairments and in mass transport Method for boarding and disembarking a passenger with a mobility impairment in a vehicle

technical field

The present invention relates to the field of mechanical and automotive engineering, in particular to the field of engineering of workpieces, parts and accessories intended to provide accessibility for passengers with mobility impairments in vehicles for public transport, and provides a mobile A system for a passenger with a mobility impairment includes a seat movable between a loading/unloading position on the exterior of a vehicle and a travel position inside the vehicle. Furthermore, the present invention provides a method of boarding and disembarking passengers with mobility impairments in a public transportation vehicle.

Background technique

People with mobility impairments—particularly those who rely on wheelchairs, crutches, canes, walkers, companions, or equivalents to ambulate or even those who are able to get around on level ground without the aid of equipment but climb stairs, People who experience difficulty walking or those who rely on handrails and/or supports to move from one place to another - daily face a range of difficulties in performing common behaviors not usually designed for people without any mobility impairments .

People with mobility impairments consist of people who present with physical disabilities (paraplegics, quadriplegics, people without limbs, people with insufficient muscle strength, people with weak bones, people with motor coordination problems, and other disabilities) or People with their temporary mobility impairments (people with broken limbs, people recovering after surgery, people who have fainted, and people with other disabilities) are defined.

Among the common behaviors faced by the group defined as persons with mobility impairments, entering a transport vehicle stands out, where a certain effort must be made to reach the seat of the vehicle and thus travel safely.

Some solutions already in the prior art (such as those disclosed by documents GB2331504, US3,236,556, US5,769,480, US2004/189,075, US2013/113,258, WO2008/097531) are specifically intended to allow driving for passenger vehicles crew and/or passengers. Such vehicles have special characteristics - they are relatively low relative to the ground, have a travel seat height close to wheelchair height or even close to normal chair height, and therefore only require the occupant/user to be able to sit at or from a normal chair height Their wheelchair slides onto the vehicle seat. Some solutions even extend the vehicle seat to the outside of the vehicle to facilitate the passengers/users getting into the vehicle, freeing them from worrying about any collision between their head and the roof of the vehicle, thus making the process more comfortable.

However, the height of the travel seats and/or the floor of the vehicle interior area relative to the ground is much higher in public transport vehicles than in passenger vehicles, which presents even greater difficulties for passengers with mobility impairments to enter.

In the context of public transport, trains, subways and buses with raised platforms aim to level the height between the floor of the access platform and the level of the interior of the vehicle, thus allowing easy access to its interior.

Another prior art solution, as disclosed in document EP 2246022, is to use a lifting platform to move passengers vertically up to the level of the vehicle floor. This solution is commonly used in buses and lifts passengers from the level of the sidewalk to the level of the bus floor. Once a passenger enters the vehicle, he/she needs to move to one of the seats in the vehicle or, in some cases, secure the wheelchair somewhere inside the bus by means of a latch and/or seat belt, thereby allowing the entire journey keep the passenger in his/her own wheelchair.

When compared to a passenger car, the floor of the bus interior has an overall higher height relative to the ground due to the stronger components (box, engine, transmission, differential and other compartments) and also because of having to raise the relative The height above the ground allows the vehicle to move over undulating, uneven terrain and locations with changes in relief without causing the floor to contact or lock up with the ground.

In this regard, a road bus has an additional factor that will increase the height of the vehicle's floor in relation to the ground, the fact that a road bus also needs to include luggage racks for transporting passengers' luggage and belongings, and It is therefore the most important case related to the height of the floor relative to the ground.

In the area of accessibility, road buses also face the problem of obstruction of internal transport space due to wide seats (to provide passengers with comfort during long journeys) without exceeding the vehicle width limit established by traffic regulations. resulting in reduced internal space. For this reason, wheelchair access along corridors is not possible, nor is it possible to provide areas to accommodate wheelchairs, since providing areas to accommodate wheelchairs would result in fewer seats, affecting the transport company's profits, and causing Passenger discomfort - Passengers are forced to travel in their own wheelchairs.

For road buses, access to the interior is usually achieved by transporting passengers with mobility impairments up stairs and through often narrow inaccessible spaces. In this regard, some solutions of the prior art (such as AT9264, CA1168183, DE102008007164, EP2636396, JPS63272350, US4,306,634, US2004/022,614) disclose lifts for transporting passengers with mobility impairments upstairs, but when Passengers with mobility impairments still need to be transported or moved with difficulty when reaching the interior of the bus. In these buses, the entry of persons with physical disabilities is mandatory with the assistance of a third party who needs to transport such passengers by legs up to the first seat of the vehicle, which is usually intended for Passengers with special needs. Such handling may cause discomfort and embarrassment to the passenger, thereby discouraging him/her from making such a journey.

In recent years, much work has been done to make public environments more accessible to all types of public, so that even people with physical disabilities or mobility impairments can travel without great difficulty and have access to any public environment. It should be noted, however, that problems remain in situations where a person with mobility difficulties wishes or needs to travel by using a public transportation vehicle. Such vehicles present an inefficient solution in adapting to receive passengers who fit the situation.

Therefore, there is a need to develop a device that allows passengers with mobility impairments to board without restraint in a simplified manner and ensures their comfort and safety during boarding and disembarking and throughout the journey.

As shown in the literature, no document was found to solve all the problems presented in the prior art and anticipate or imply the teaching of the present invention, so in the inventor's opinion, the solutions proposed herein are incompatible with the prior art. than novelty and innovation.
