ABSTRACT:
A bed and/or chair device comprises a stand (1) and a support surface arrangement (2, 3, 4), which is divided in at least two mutually movable parts, namely a back support (2) and a thigh supporting and possibly also seat supporting part (3), the back support (2) and the thigh supporting part (3) being pivotably connected to the stand (1), a power means (11) being arranged to cause a pivoting movement of the back support (2) between different inclination positions with respect to the stand (1). A transmission arrangement is arranged to make the movement of the back support and the thigh supporting part dependent on each other, so that, in pivoting the back support (2) upwardly from a substantially horizontal position, the thigh supporting part (3) is initially pivoted upwardly with respect to the stand (1), until a maximally raised position is reached, after which a continued pivoting upwardly of the back support causes the thigh supporting part to pivot downwardly towards its initial position.
