Abstract
Abstract A vehicle passenger seat located adjacent to the driver is equipped with a backrest and can be swung past the dashboard of a motor vehicle by first pivoting the backrest forward, a rearward sliding movement being superimposed on the pivoting movement because a bracket receiving the backrest pivotably is provided with a guide device and a displacement of the bracket together with the backrest is produced by means of a supporting lever arrangement.
