摘要

The wheelchair (10), preferably with three wheels (18, 24) with a front wheel support (12.1), which is designed as a cross support; the front wheel support (12.1) forms, together with two of its ends adjoining, rearwardly upward oblique supports (12.2) and the subsequent two of the helical support (12.2) longitudinal beams (12.3) has a U-like integral support coated with an axle tube (14) of the rear wheels (18).The wheelchair (10) having an adjustable inclined lateral longitudinal seat supports (56) having the seat (52); the seat side members (56) are with their front ends directly and with their rear ends on seat stays (72) of variable effective length struts with rearwardly downwardly inclined longitudinal members (12.3) of the frame of the wheelchair (10)-jointed.Wheelchair with adjustable inclination of the rear wheel axes, the axes configured as a plug rear wheel axles in end portions of a rear axle tube (14.1, 14) are accommodated, in angle adapter sleeves (22). This angle adapter sleeves comprise a portion with a bore (22.2, 122.2) for receiving the plug-in axis and a portion (22.3, 122.3) with a stop surface which runs obliquely to the axes of these bores (22.2, 122.2). The angle adapter sleeves (22) are in the end regions of the axle tube (14.1, 14) accommodated longitudinally displaceably. A fixing device (22.7, 22.8) is provided for each angular adapter sleeve (22) optionally in a fixing of a plurality of positions. However, the seat module (50) for a wheelchair (10) comprising a frame (12.3) of the wheelchair (10) can be fastened seat (52) and one at the seat (52) unattached to the frame of the wheelchair (10) can be fastened back (54 ), and use of the seat module(50) to a wheelchair (10).Use of a wheelchair (10) including a bike, and is changed to prevent the backward tilting of the wheelbase of the wheelchair (10) by the rear wheels (18) are brought from their usual position in a further back position.
