Abstract: A frame for a wheelchair, to which wheels and a seat may be fixed, comprises a seating surface section for mounting a seating surface and a backrest section for mounting a backrest. The backrest may be folded into a position running essentially parallel to the seating surface. A wheelchair with such a frame may be arranged in a novel manner in a space-saving form. The backrest section may be folded into a transport position within the frame and beneath the seating surface section.

Abstract: The invention relates to a seat shell which is especially designed to be mounted on the chassis of a wheel chair or a stroller, and that comprises adjustable support elements (34) for supporting the person seated in said seat shell. The aim of the invention is to provide a seat shell with which the position of the seated person on the seat can be fixed by easily adjustable and reliably fixable support elements. To this end, the support elements (34) are disposed above the two lateral edges of the seat (2) and their distance to each other in the transverse direction of the seat (2) is adjustable.

Abstract: The invention relates to a seat frame for fitting to the running gear (15) of a wheelchair or pushchair, comprising a backrest (1), a seating surface (2) and feet support (3). The aim of the invention is to produce a seat frame which is particularly flexible and may be adjusted to various sizes. Said aim is achieved, whereby long recesses, in particular grooves (5), are arranged running longitudinally along both sides of the seating surface (2), for housing fixing elements. Preferably, long recesses, in particular grooves (5), are also arranged running longitudinally along both sides of the backrest (1), for housing fixing elements.

Abstract: Described herein is a traveling seat, such as a wheelchair, for physically handicapped persons. The seat has a seat shell mounted on a frame, where the shell includes a backrest and a seat surface, connected with one another with articulation, with a footrest being articulated pivotably to the forward end of the seat surface. In order to provide a seat that can follow the bodily movements caused by spasms of the person seated in the seat, the seat surface and backrest are connected, freely pivotably, with one another. A tensioning device generating a tensioning force that holds the seat surface and the backrest in the bent sitting position relative to one another is provided. In addition, the footrest is articulated in a freely pivotable fashion to the seat surface, with a tensioning device generating the tensioning force that holds the footrest in the bent sitting position relative to the seat surface.
