The invention relates to a wheelchair, comprising a frame (10), drive wheels (11) arranged on the frame (10), at least one steerable steering wheel (12), and a seat (14), the height (H) and inclination (N) of which can be set, the height being adjustable by means of a link parallelogram gram (I, II), which is formed by a first link (1) rigidly connected to the frame (10), a second link (2) and a third link (3) connected to the first link (1) in an articulated manner, and a fourth link (4) connected to the second link (2) and the third link (3) in an articulated manner and which is connected to an actuator (6), the wheelchair being characterized in that the link parallelogram (I, II) comprises exactly four links, the seat (14) is pivotably arranged on the hinge point (C) formed by the third link (3) and the fourth link (4), and a second actuator (7) is provided, which is connected to the seat (14) and to one of the links (1, 2, 3, 4).
A wheelchair with a frame (10), drive wheels (11) arranged on the frame (10), at least one steerable steering wheel (12), and a seat (14) which is adjustable in height (H) and inclination (N), the height being adjustable by means of a link parallelogram (I, II), which is formed by a first link (1), rigidly connected to the frame (10), two second (2) and third (3) links, connected to the first link (1) in an articulated manner, and a fourth link (4), connected to the second (2) and third (3) link in an articulated manner, and which is connected to an actuator (6), characterized in that the link parallelogram (I, II) is composed of exactly four links, in that the seat (14) is arranged pivotably on the hinge point (C) formed by the third (3) and fourth (4) link, and in that a second actuator (7) is provided, which is connected at one end to the seat (14) and at the other end to one of the links (1, 2, 3, 4).
The wheelchair as claimed in one of the preceding claims, characterized in that the first actuator (6) is secured at one end on the frame (10) and at the other end on the second link (2).
The wheelchair as claimed in one of the preceding claims, characterized in that the second actuator (7) is connected to the fourth link (4).
The wheelchair as claimed in one of the preceding claims, characterized in that two identically designed link parallelograms I, II are provided.
