An exemplary seat having seat connection mechanism for attaching the seat to a wheelchair includes a seat frame and a backrest. The backrest is pivotably connected to the seat frame through a pivoting mechanism. The seat further includes a biasing member connected to the backrest at a first connection point and a second connection point near the seat frame. The second connection point and the pivoting mechanism are spaced apart from one another by a distance C. The seat further includes an adjustment mechanism adapted for changing the distance C. The second connection point may be connected to a guide arm, such that the position of the second connection point is adjustable by sliding the second connection point along the guide arm, thus making the distance C adjustable.

Seat

An articulated joint pivotably connects first leg and second legs. A first joint member attaches to the first leg. A second joint member attaches to the second leg. The joint members have facing abutment surfaces. Each joint member has a shaft opening receives a shaft for connecting the joint members, such that the legs may pivot between an open and a closed position. A clamping means releasably presses abutment surfaces of the joint members toward each other. A locking means releasably positively secures the joint members in at least the open position. Each joint member has a first aperture. The first aperture is radially offset from the shaft opening. The first apertures of each joint member are coaxially arranged in at least the open position. A device for supporting a person is included.
