A wheelchair ( 1 ) is described. The chair comprises a seat ( 2 ) and a back ( 3 ) that are pivotally supported in two side members ( 4, 5 ) and are kinematically interconnected in such manner that an angle between the seat and the back will increase when the back is swivelled backwards about is pivotal support in the side members, which kinematic connection comprises a link connection between the seat and the back. The link connection is in the form of a link arm ( 12 ) arranged under the respective pivot supports of the seat and the back so that the distance between the back pivot support ( 15 ) and the back link arm connection ( 13 ) is less than the distance between the seat pivot support ( 16 ) and the seat link arm connection ( 14 ), and that the axis of rotation ( 20 ) of the seat through the seat's pivot support ( 16 ) in the side members passes essentially through or close to the user's centre of gravity ( 17 ).
