A child safety has a base (1), comprising a base inner shell (2) and an occupant support surface (4), and a back 6, comprising a back inner shell (7), integral backrest 8 and side wings (9). Base (1) and back (6) are pivoted together by hinge (10). Back (6) has a height adjustable a headrest (11), releasable by push surface (12) and provided with upper seat belt guides (14). The seat has two lower seat belt guides (21) at the junction between back side wings (9) and sides (22) on base shell (2). With back (6) pivoted as far forwards as possible (in Figure 2) guides (21) are defined entirely by invert U-section outer formations (24) which are moulded integrally with base inner shell (2). With back (6) reclined (in Figure 3) inner formations (25), moulded integrally with side wings (9), are visible and are accommodated inside outer formations (24). Inner formations (25) close the gap between outer formations (24) and wings 9 when the seat is reclined so that an adult seat belt B cannot pull between the shell mouldings. Invert U formations (24) comprise plain webs (31) and inner formations (25) comprise plain outer webs 34 and reinforcing flanges (35), which face inwards. The width of inner formations (25) is such as to allow clearance with the outer formations (24), but no more, for the back to pivot freely. |
