Abstract
Abstract A safety seat for the conveyance of babies and small children in vehicles, including a holder frame, a seat shell swivelably on the holder frame for pivotal movement about a swivel axis and so as to define an area of overlap between a bottom of the seat shell and the holder frame, and structure for locking the seat in a plurality of angular positions relative to the holder frame, this structure including a locking catch in the area of overlap between the bottom and the holder frame, and being spaced far distant from the swivel axis. The locking catch includes a locking member manually retractably shiftable into locking engagement with the holder frame when the seat frame is in any one of the angular positions.
