Abstract (en)
In order to make it easier to stand up from wheelchair (1), the top part (3) of the wheelchair (1) is arranged tiltably with respect to the bottom part (2). A spring element (4), which comprises a gas spring (7), assists with the forwards tilting. According to the invention, the spring element (4) also comprises a coil spring (8) with a preferably adjustable free travel (A). This facilitates moving the top part (3) upwards from the rear position without making the backwards tilting significantly more difficult. The coil spring (8) also ensures that a spring action is always maintained, even if the gas spring (7) should fail. <IMAGE>
