We are not really sure what NOA stands for, but as it is being reported by Basque Research, this new high-tech chair from Tekniker-Ik4 is designed to have a small footprint for greater maneuverability, and features a vertical seat lift to help reach objects.
NOA is amongst the state-of-the-art range of wheelchairs with additional functions which go beyond the mere transport of users and aimed at facilitating the activities of their daily lives.
One of the main ideas proposed is that of wheelchair be an interior-exterior one, overcoming the contradictory specifications to date whereby, on the one hand, a wheelchair is small sized (width-length) in order to pass through doorways, travel in lifts or have a small turning circle, etc, and, on the other, have good stability, a good grip on the floor and a certain ability to overcome obstacles (mainly edges), when used outside. In general, users of motorised wheelchairs also have a manual wheelchair for use in interiors, given its greater manoeuvrability. The characteristics of the new wheelchair enable users to operate a single machine in all the ambits of their daily lives.
The design challenge was met by developing an extension mechanism that enables the equipping of the NOA with variable geometry as a function of the needs of the moment, providing high manoeuvrability in its compact position in interiors and small spaces (smaller turning circle for use in lifts and restricted spaces, less width for negotiating narrow doorways and so on) and maximum stability in its extended position for use outside (greater width and greater separation between front and rear axles, while maintaining the overall length of the wheelchair).
NOA also incorporates vertical seat movement, both above and below the driving position, a feature not available in current market models. The vertical positioning of the seat above the driving position enables the users to reach high objects, gain access to counters, have conversations at different heights, etc. Being able to lower oneself from the usual driving position enables access to standard tables and desks, eat with a more suitable posture, pick objects up from the floor, etc. Moreover, the sum of both these movements enables lateral transferences at different heights to be carried out, thus reducing both the physical effort required by users or their helpers or carers as well as the need for additional devices such as transfer cranes.
NOA has the same adjustable directional tilting specification so that the user can change position without discomfort or rigidity in the joints, as well as avoid body sores, due to the fact that the points of support for the body can be changed.
The technology developed enables the integration of a single device to operate both the vertical movement of the seat as well as its directional tilting. NOA also incorporates another series of function, based on new technologies, aimed at increasing safety (automatic calls to emergency services and/or to family members for detection of falls by the user or the wheelchair overturning, detection of obstacles and anti-collision systems), manoeuvrability (semi-automatic help in the manoeuvre for negotiating edges) and facilitating control (remote control and pre-programmed itineraries).
