The wheelchair (10) has a closed, three-dimensional frame (12). The latter is constituted by a front horizontal transverse support (12.1), two lateral supports (12.2, 12.3), which are arranged symmetrically in respect to the longitudinal center axis, and a rear, essentially horizontal transverse support (14). The lateral supports have the shape of a letter L with respectively an upright leg (12.2), which laterally adjoins the front transverse support (12.1), and with a rearward oriented longitudinal leg (12.3). A front wheel support (25), on which a front wheel (24) is mounted, is fastened on each upright leg (12.2) of the longitudinal supports.

[ What is claimed is:] [1.]1. A wheelchair with a closed three-dimensional strutless frame, said frame consisting of:a transverse axle tube for a pair of rear wheels,two lateral portions extending forwardly from said axle tube, each said lateral portion being unitary and having the shape of a reverse letter L, said two lateral portions being arranged symmetrically with respect to the longitudinal central axis of the wheelchair, and each L-shaped lateral portion consisting essentially of a generally longitudinally extending upper leg and a generally vertically extending lower leg at the front of said wheelchair, said upper leg having a rear end connected to said axle tube and a front end, and said lower leg having an upper end connected to said front end of said upper leg and a bottom end,a lower transverse horizontal front portion at a height to support the user's feet having two side ends respectively connected to bottom ends of said lower legs of said lateral portions, andfront wheel supports, each of which is attached on the lower leg of a respective one of said lateral portions.
