Definitions
- the chassis frame consists of two cross braces with each other via a seat connected side frame parts between a spaced use position and an adjacent collapsed position essentially parallel to each other movable and at least in the position of use are lockable.
- On the side frame parts which are made of there are tubes welded to one another one rear drive wheel each and one each around a swivel castor mounted on a vertical axis.
- the Cross strut consists of each other in such wheelchairs crossing tubes or handlebars at the crossing point hinged together and with their lower ends each on a lower frame tube of a side frame part are articulated. With the other ends of the the tubes or handlebars that form the cross strut are seat tubes firmly connected, along which the longitudinal edges mostly consist of strong canvas existing seat attached and the with the upper frame tubes of the side frame parts in the position of use can be locked.
- Such a design of the bearing elements enables a particularly simple assembly in such a way that the bearing parts with their unilaterally open inventory the lower frame tube of a side frame part is attached and then the one at the bottom of a crossbar handlebar arranged holding shoe from the open side of the bearing part pushed onto this and then with the bearing part firmly but releasably connected.
