Abstract:
A height adjuster for a vehicle seat that is equipped with a belt lock of a seat belt, the height adjuster comprising:a rocking arm pivotably mounted to a seat frame for pivoting relative to the seat frame to adjust the height of the seat frame, with the rocking arm including a toothed segment; and a connector including a lever and a pawl that are positioned on opposite sides of the seat frame and mounted to the seat frame so that the lever and the pawl move together with the seat frame relative to the rocking arm when the height of the seat frame is adjusted, wherein: the lever and the pawl are connected to one another for corotating relative to the seat frame about an axis of rotation, with the axis of rotation being perpendicular to the seat frame, the lever includes a mounting point for the belt lock, the lever and the pawl corotate about the axis of rotation relative to the seat frame in response to a predetermined force being applied to the mounting point for the belt lock, so that an engagement mechanism of the pawl engages and transmits force to the toothed segment of the rocking arm, the engagement mechanism engages a first section of the toothed segment when the seat frame is at a first adjusted height and the lever and the pawl corotate about the axis of rotation relative to the seat frame in response to the predetermined force being applied to the mounting point for the belt lock, the engagement mechanism engages a second section of the toothed segment, which is different from the first section of the toothed segment, when the seat frame is at a second adjusted height, which is different from the first adjusted height, and the lever and the pawl corotate about the axis of rotation relative to the seat frame in response to the predetermined force being applied to the mounting point for the belt lock, and the axis of rotation is arranged between the engagement mechanism and the mounting point for the belt lock.
