A seating module for use with a chair frame includes a perimeter frame member. A resilient internal platform is attached to the perimeter frame member at a static portion. An upper seat cushion is disposed on top of a resilient internal platform. The resilient internal platform is biased to an original shape that defines a resting position. Upon a patient resting upon the resilient internal platform, the resilient internal platform deflects in a downward direction toward a seating position and contemporaneously exerts an upward biasing force that assists the patient in reaching a seated position and also assists the patient is moving upward from the seated position.

An extendable cushion assembly includes a cushion that is movable between an extended state and a retracted state, and a base upon which the cushion is removably coupled. The base is movable between an extended state and a retracted state. When the cushion is coupled to the base and when the base adopts the extended state or the retracted state the cushion is configured to adopt the extended or the retracted state respectively.

A wheelchair system includes a wheelchair including a plurality of force sensors including at least three force sensors. A rigid seat pan is placed in contact with each the plurality of force sensors at a different position on the rigid seat pan so that the rigid seat pan does not contact the frame and forces on the rigid seat pan are transferred to the plurality of force sensors. Each of the plurality of force sensors is in communicative connection with a processor system. A memory system is in communicative connection and an interface system is in connection with the processor system and a user interface system in communicative connection with the processor system. Instructions stored on the memory system are executable by the processor system to determine a value of a variable related to a distribution of force on the rigid seat pan over time.

A transfer machine includes a main body assembly and a lifting assembly. The main body assembly includes two lifting rods capable of moving up and down and two seat plates facing the lifting rods. Each seat plate can rotate around the corresponding lifting rod thereby enabling the two seat plates to close or separate from each other. The lifting assembly includes a base, a connecting rod and a control assembly fixedly connected to the lifting rods. The base includes two guiding rods extending up and down, and each lifting rod can move in the up-down direction along the guiding rod. The control assembly includes a pushing rod, connected to the connecting rod; and a drive arm, driving the lifting rods to move in the up-down direction, thereby driving the main body assembly to move up and down. The connecting rod includes two foot sections.

A multi-position airflow control assembly includes a valve housing, a valve body received by the valve housing, a plurality of connectors coupled to the valve body, each connector configured to fluidly connect to an inflation zone of a cellular cushion, and a control assembly partially received by the valve body. The control assembly includes a seal member, and an actuation assembly operably connected to the seal member and configured to rotate the seal member relative to the valve body. The seal member is configured to rotate between a first position and a second position.

A multifunctional wheelchair contains: a body, a support plate, a lifting seat, and a shampoo basin. The body includes a retractable mounting, a chair back, at least one drive device, and two frames. The two frames have two main wheels, the two frames have two guide wheels, and the two armrests are arranged on a second drive device. A respective armrest has an abutting portion, and the retractable mounting have two racks. The support plate is detachably engaged on the retractable mounting of the body. The lifting seat is removably engaged on the retractable mounting of the body, and the lifting seat includes a saddle on a third drive device which is configured to drive the saddle to lift or descend adjustably. The shampoo basin is detachably connected on the chair back and included a washing chamber.

A modular seat apparatus includes a base cushion and a back cushion that includes a plurality of segments defining a longitudinal length of the back cushion. The back cushion is pivotably coupled to the base cushion such that the back cushion is oriented at an angle relative to the base cushion. The plurality of segments is configured to translate in response to the back cushion pivoting relative to the base cushion such that the longitudinal length of the back cushion decreases as the angle increases and the longitudinal length of the back cushion increases as the angle decreases.

A therapy seat cushion, method of making the cushion and method of using the cushion. The cushion has a planar array of at least two sets of alternatively inflatable and deflatable cells controlled by an inflation control system, and at least one non-inflatable offloading cushioning cell interspersed amongst the inflatable cells. The non-inflatable offloading cushioning cell configured and arranged to align with a pressure sore or an area prone to development of a pressure sore on an individual.

In an electric vehicle, a seat on a mobile base can move between a sitting position in which a sitting surface faces the vehicle upper side, and a retracted position in which a seating portion having the sitting surface is retracted from the sitting position to the vehicle front side, a back plate on the mobile base can move between a raised position on the vehicle rear side and the vehicle upper side with respect to the seating portion in the sitting position, and a laid down position on the vehicle front side with respect to the raised position, a cargo bed portion on the mobile base is positioned on the vehicle lower side with respect to the seating portion of the seat in the sitting position and is positioned on the vehicle rear side with respect to the seating portion of the seat in the retracted position.

A seat arrangement (10) for a wheelchair, as well as a wheelchair (40) incorporating such a seat arrangement (10), are disclosed. The arrangement includes a base, a connecting member and a supporting member. The base forms part of or is mounted to a seat of the wheelchair (40). The connecting member is slidably mounted to the base and displaceable relative to the base between a retracted position and an extended position. The supporting member is pivotably connected to the connecting member and shaped substantially so as to mate with the seat opening (22). The supporting being member is pivotable between an open position and a closed position. When the connecting member is in the retracted position and the supporting member is in the closed position, the supporting member mates with the seat opening (22) to define a sitting surface, and when the supporting member is in the open position, a seat opening (22) is exposed.
