An ergonomically designed seating apparatus having a seat and a backrest. The seat having a seat frame securable to a chassis, a seat support pivotally connected to the seat frame, and at least one first resilient member positioned between the seat frame and the seat support permitting resilient relative pivotal tilting between them. The backrest having a back frame securable to the chassis, a lumbar support connected to the back frame, a back support pivotally connected to the lumbar support, at least one second resilient member positioned along surfaces of the lumbar support and the back support permitting resilient relative pivotal tilting between them, at least one pivot arm connected to the back support configured to limit the pivotal range of motion of the back support, and at least one pivot block connected to the lumbar support configured to interact with the at least one pivot arm.

An assistive apparatus with a backrest assembly is disclosed to solve one of the problems of conventional toilet seats in lacking proper back support for individuals. The assistive apparatus also helps to put individuals sitting further forward to help the individuals to use the toilet much more easily. The assistive apparatus provides an adjustable toilet backrest assembly for supporting a human back. The backrest assembly includes a backrest pad, a top support frame connected to the backrest pad, and a bottom support frame. The backrest pad is designed to relieve pressure on the back of a person. The back support portion comprises a backrest frame and a back pad attached on the backrest frame for supporting the human back. The backrest frame provides means for adjusting height of the back pad to accommodate different height of the human back. The angle adjustment portion connects to the back support portion with the toilet mounting portion and provides an angle adjustment means for different position of sitting on toilet.

An assistive apparatus with adjustable height is designed to be placed on or about a toilet such that when an individual uses the toilet the weight of the individual is transferred to the assistive apparatus and not directly on the toilet, avoiding distribution of heavy weight to the toilet itself. The invention also includes a powered lifting mechanism to aid the individual in utilizing a toilet. The powered lifting mechanism includes a pair of lift arm assemblies which are driven by a motor at both sides to raise and lower the assistive platform and be tilted between a first stationery position and a second tilted position, tilted at an angle (a) in a vertical Z direction from a horizontal plane. The front and back supporting legs are used to provide sturdy structural support for a person's weight whiling sitting on the assistive apparatus atop of a toilet.

An assistive apparatus with a buttock-spreading mechanism suitable for assisting a person in getting onto a toilet is disclosed. The person using the toilet together with the assistive apparatus is able to transfer the bodyweight of the person to be supported by the assistive apparatus, thereby avoiding the transfer or distribution of the person's heavy weight directly to the toilet itself. The buttock-spreading mechanism includes expandable leaflets disposed on a platform to comfortably accommodates the dimensions of the person's buttocks, and the leaflets of the buttock-spreading mechanism is designed to be movable (e.g., expanded or retracted) for spreading the buttocks of the person.

A transferable wheelchair width adjuster that can be attached to the lower frame of a folding wheelchair allowing the wheelchair to be narrowed to varying widths so as to accommodate entry through doorways that otherwise would be impassable. Narrowing the profile of a standard wheelchair also allows the chair to accommodate more comfortably a smaller individual, such as a small child. No modification of the original wheelchair construction is necessary. The width adjuster described herein can be attached and removed manually without the need of tools.

An ergonomically designed seating apparatus having a seat and a backrest. The seat having a seat frame securable to a chassis, a seat support pivotally connected to the seat frame, and at least one first resilient member positioned between the seat frame and the seat support permitting resilient relative pivotal tilting between them. The backrest having a back frame securable to the chassis, a lumbar support connected to the back frame, a back support pivotally connected to the lumbar support, at least one second resilient member positioned along surfaces of the lumbar support and the back support permitting resilient relative pivotal tilting between them, at least one pivot arm connected to the back support configured to limit the pivotal range of motion of the back support, and at least one pivot block connected to the lumbar support configured to interact with the at least one pivot arm.

A wheelchair including a supporting frame and moving means configured to allow the movement of the wheelchair, the supporting frame having a seating area for a user of the wheelchair, the wheelchair including first actuation means configured to translate the seating area laterally and externally with respect to the supporting frame and, at least partially, with respect to the moving means, in a transfer configuration of the user, supporting means being operationally associated with the seating area, being able to be activated in the transfer configuration of the seating area to support the seating area with respect to the ground, the seating area being defined, in the transfer configuration, by a main seat and a secondary seat able to be activated in the transfer configuration of the seating area to increase the extension of the main seat.

A wheelchair frame comprises a base frame having a geometry that is structured and configured to be adjustable about a fixed pivot, wherein the base frame comprises a central frame and frame component that are adjustable via an angular adjustment.

A front wheel and a rear wheel are to be provided at a grounding frame. A body frame is mounted on the grounding frame and includes a mount at which a seat is to be provided. A relative position between the grounding frame and the body frame in a height direction of a wheelchair is changed via a height adjustment mechanism. The height adjustment mechanism includes an adjustment pole, a pole reception, and a holding portion. The adjustment pole extends along the height direction and is mounted on one of the body frame and the grounding frame. The pole reception is mounted on another of the body frame and the grounding frame and is engaged with the adjustment pole slidably in the height direction. The holding portion is to hold not to relatively move the adjustment pole with respect to the pole reception.

A seat assembly for wheelchair of the type having a structure expandable from a contracted condition to an expanded position comprises a pair of tubular members connected to the structure. Each tubular member has a main tubular body, a secondary tubular body parallel to and inside the main tubular body, and an elongated slit extending along both the main tubular body and the secondary tubular body and common to both the main tubular body and the secondary tubular body. The slits open into an inner channel of the secondary tubular body. The main tubular body and the secondary tubular body form a hollow integral piece of composite material. A panel, e.g., of non-rigid material has rods on its opposite edges, the rods having a diameter smaller than that of the secondary tube and larger than a width of the slit to be held captive in the secondary tube, whereby the panel extends through the slit.
