Abstract
A backrest device includes a backrest carrier having a support arm, a backrest mounted on the support arm, and an actuator that is adjustable between a blocking position and a movement position. The support arm is equipped with a latching row. The backrest is movable along the support arm. The actuator is connected to the backrest and has an engaging piece. In the blocking position, the engaging piece is engaged with the latching row, so that a movement of the backrest along the support arm is blocked. In the movement position, the engaging piece is disengaged from the latching row, so that the backrest is movable along the support arm. The actuator is manufactured in one piece from an elastic material, in the movement position the actuator being elastically deformed by a manually applied force, so that the engaging piece is moved out of the latching row.
