A car seat is formed with a seat member pivotally connected to a base member for positional adjustment in desired reclined positions controlled by an intuitively operable adjustment mechanism. The seat back is pivotally connected to the seat member to be oriented in a shipping position or an operative position. A latching mechanism secures the seat back to the seat member in the operative position. The seat back is provided with a head rest that is vertically movable relative to the seat back to uncover routing openings in the seat back as the child grows and the head rest is positioned accordingly. The harness is routed through selected routing openings in the seat back before passing over a hanger at the top of the seat back so that the length of the harness remains constant irrespective of the positioning of the harness in conjunction with the size of the child.

The apparatus is an infant seat that has reduced depth for shipping and recline controls that permit control of the seat during the reclining adjustment. The seat is constructed so that the deepest part of the seat fits into the rest of the seat for packaging, but locks into its proper location for use. The preferred embodiment of the recline control uses a dial on a seat pivot fixture. The dial is pushed in to release the seat for reclining, but the dial is interconnected with the seat so that the dial maintains full control of the seat movement. An alternative recline control captures and releases a support wire at the backside of the seat.

A work light cage attachment system which includes a cage that securely attaches over the glass opening on a work light. The cage includes opposite top and bottom frame members and opposite side frame members. Attached to the comers of the top and bottom frame members are rearward extending legs. Each extending leg includes a perpendicularly aligned foot that, during assembly, is placed inside the gap between the edge of the faceplate and the glass and extends outward to prevent disengagement of the cage from the faceplate. Attached to each foot on the top and bottom frame members is a C-shaped clip which engages a raised lip formed on the inside surface of the faceplate. The lips prevent the cage from being removed from the work light without a tool, thus meeting United Laboratories code.

The invention discloses a shearing fork bending metamorphic mechanism type manipulator. Each manipulator claw comprises a plurality of metamorphic mechanism units which are connected in series, wherein each metamorphic mechanism unit comprises a plurality of secondary metamorphic mechanism units which are connected in parallel; and each secondary metamorphic mechanism unit comprises a shearing fork mechanism and an aberrant shearing fork mechanism.
