The present disclosure generally relates to a manifold valve assembly engaged to an inflatable apparatus, such as a cushion to prevent pressure ulcers, for example. The manifold valve assembly is also in communication with a processing device to determine an optimal immersion level for a user seated on the inflatable apparatus. Additionally the processing device, in communication with the manifold valve assembly may save optimal immersion or air pressure levels for comparison to future checks of cushion pressure and send that to a user interface at the processing device. The assembly and processing device may also save and dis play a history of pressure checks.

An apparatus is configured for use with a chair having a supporting surface, and includes a bottom member adapted to be placed above the supporting surface of the chair. The bottom member includes a cushioning member in the form of a bladder. The bladder includes at least two internal chambers. A first of the at least two internal chambers extends from a rear edge disposed inwardly proximate a center of the bladder and a second of the at least two internal chambers extends peripherally around three inner sides of the first internal chamber. The apparatus further includes a top member having a bottom surface positioned in confronting relation to the bottom member and a top surface opposite the bottom surface.

A lifting system for lifting a subject (12) supported in a particular position is described. The lifting system has a platform (10) for supporting the subject (12) on an elongate platform surface (101). The platform surface (101) is selectively configurable in a flexible state allowing the elongate platform (10) to fold along a longitudinal line for positioning beneath the subject (12), and a rigid state to support the subject (12) in the desired position. The platform also has one or more attachment structures (16) and, the lifting system has a lifting device (26) for detachably engaging (18) the one or more attachment structures (16) to elevate and lower the platform (10) cantilevered from the lifting device (26).

Multi-layer cushion supports are described which may generally comprise a first support having a first contact surface for contacting a portion of a body and a second surface opposite to the first surface, the first support defining a central chamber and a peripheral chamber surrounding the central chamber, wherein the first support is filled with a first gas or liquid and a second support attached to the first support along the first contact surface. The second support may be filled with a second gas or liquid which is relatively more viscous than the first gas or liquid. In particular, the first support may be filled with a volume of air and the second support may be filled with oil which is less than the volume of air.

There is described a bariatric wheelchair, in particular a manual wheelchair, that includes a wheelchair chassis, a seating area provided on the wheelchair chassis, a backrest supported onto the wheelchair chassis, as well as front wheels and rear wheels provided on the wheelchair chassis to allow wheeling of the wheelchair. The backrest exhibits a lower backrest portion supported onto the wheelchair chassis, next to the seating area, the seating area and lower backrest portion having a first width (W1) that is selected to accommodate a wheelchair user's nominal hips width (WH) ranging between 500 millimeters and 800 millimeters. The backrest further exhibits an upper backrest portion, in the vicinity of the wheelchair user's shoulders, having a second width (W2) that is smaller than the first width (W1), which second width (W2) is selected to liberate space for movement of the wheelchair user's arms and shoulders and so as not to exceed a wheelchair user's nominal shoulder articulation width (WS) ranging between 400 millimeters and 600 millimeters.

There is described a wheelchair, in particular a manual wheelchair for bariatric or heavy-duty use, that includes a wheelchair chassis, a seating area, a backrest, as well as front wheels and rear wheels, said backrest having a backrest frame supported onto the wheelchair chassis. The wheelchair further includes a rolling support structure forming an integral part of the wheelchair, which rolling support structure is mounted on a rear portion of the wheelchair to support the wheelchair in an upright position in which the wheelchair is tilted back and is supported by the rolling support structure to allow displacement of the wheelchair in the upright position. The rolling support structure includes at least three, in particular four, rolling elements providing rolling support for the wheelchair in the upright position. The rolling elements preferably provide omnidirectional rolling support for the wheelchair in the upright position, and may in particular be ball casters

A seat for a mobility device accommodating flexibility, personalized comfort, and transportability. The seat can include a button push means to enable movement of a height-adjustable armrest. The seat back can fold upon the seat for transportability. The seat cushion and armrest cushion can be removably mounted and separately replaceable. The seat can be mounted upon various types of devices, including, but not limited to, wheelchairs.

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.

An apparatus is configured for use with a chair having a supporting surface, and includes a bottom member having a cushioning member, the bottom member adapted to be placed above the supporting surface. The bottom member has a rear edge adapted to be placed proximate a rear of the chair and a front edge opposite the rear edge. The apparatus further includes a top member having a bottom surface positioned in confronting relation to the bottom member and a top surface opposite the bottom surface. The top member and the bottom member are connected to each other along at least one of the front and rear edges, and at least a portion of the top member is slidable with respect to the bottom member. The apparatus further includes a second cushioning member connected to a rear end of the apparatus and adapted to extend upward from the rear end.

A user control device for a transporter. The user control device can communicate with the transporter via electrical interface(s) that can facilitate communication and data processing among the user interface device and controllers that can control the movement of the transporter. The user control device can perform automated actions based on the environment in which the transporter operates and the user's desired movement of the transporter. External applications can enable monitoring and control of the transporter.
