<p>An infant's chair (46) has a bar (60) which normally extends across the front of the chair (46) and which can be pivoted upwardly. The bar (60) has side arms (62, 64) which plug into sockets (66, 68) mounted on the sides of the chair (46). Each socket (66, 68) comprises a static part (70) secured to the chair (46) and a rotary part (72) secured for angular movement relative to the static part (70) about a pivot axis (76) such as to enable the bar (60) to move from its position in front of the chair (46) to a raised position in which the bar (60) can be detached from the chair (46). The rotary part (72) has a recess (82) adapted to receive the end of the side arm (62, 64) and the static part (70) has an arcuate channel (88) with a radial section (92) arranged to receive a detent projection (86) on the side arm (62, 64) so that the side arm (62, 64) can be removed from the socket (66, 68) only when the detent projection (86) is in alignment with the radial section (92) of the arcuate channel (88).</p> |
