In acceleration and deceleration arrangement comprising a carrier element connected to an energy storage spring and supported on a guide surface so as to be movable between a park position and an end position wherein a piston of a motion damping cylinder piston unit is moved by the carrier element in a deceleration stroke direction when the carrier element is moved by a tension spring from the park position to the end position, the carrier element has a spring deflection area which is abutted by the tension spring so as to apply a tilting torque to the carrier element for pivoting the carrier element into a holding section provided in the guide surface at the park position of the carrier element.
