Abstract
A foldable infant stroller comprises a frame for supporting an infant seat, the frame comprised of three U-shaped frame members which provide a push handle, a child restraint bar and a support for the front of the seat respectively, the three members being interlinked for folding and unfolding of the frame. A safety latch is provided for locking the frame in unfolded condition. The safety latch is released to allow folding of the frame by lifting up with the foot, and is thus safe against accidental release by a child stepping on the release bar.
