There is shown a frame 1 (in the case of a buggy 2) for removably supporting a seat means 3 for a child in a plurality of angular positions, comprising a manually operable lateral mechanism 4 which is adapted to support the seat means 3 whereby that seat means 3 is fixedly mountable in and releasable from the frame 1, the mechanism 4 also providing adjustment of the seat means 3 to a desired fixed angular position in relation to the frame 1. The manually operable mechanism 4 comprises a rotatable knob which allows a wedge or dove-tailed part thereof to be withdrawn from engagement with another part so that it can be rotated to a different angular position before being drawn back into engagement, when it is locked in position. To release the seat entirely, the member is rotated to a further position to withdraw cooperable locking means so that the seat can be lifted from the dove-tailed part. |
