Abstract: A seat for a child's swing is of the type having a plate-like substantially rigid member to bear the weight of a user sitting on the seat, and resilient polymeric material secured to the plate-like member. The resilient polymeric material extends beyond the outline of the plate-like member to form a border around the edges of the plate-like member, and forms a peripheral dependent skirt of substantial thickness. To achieve greater safety in use, the border includes a hinge-like portion of the resilient material, the plate-like member in the region of the hinge-like portion is configured to provide room for the dependent skirt to hinge beneath the plate-like member, and in an impact between the edge of the seat adjacent the hinge-like portion and an object, the skirt is progressively deformed and forced to hinge inwards against the resilience of the hinge-like portion.

Abstract: A folding wheelchair includes a pair of side frames which are collapsible in their own planes. There is simultaneous collapse of two pairs of strut members. The collapsed wheelchair is very compact, even though the erected wheelchair is very reliable due, at least in part, to its avoidance of areas of high stress concentration. In alternatives, the scissor-like strut members are replaced by fixed struts so that collapse in the height direction is not accompanied by collapse in the width direction.
