  • Patent number: 5186520
    Abstract: A tethering device for securing a child safety seat to an automobile seat with an automobile seatbelt. The tethering device has a cap, a base, and a wedging mechanism rotatably mounted to the base such that a wedging portion extending upwardly from the base towards the cap will move from a passive position that does not positively grip a seatbelt to a second active-locked position which does positively grip the seatbelt between a wedging surface of the wedging portion and an inside surface of the cap. The tethering devices are secured to each side of the child safety seat at a generally 45 degree angle to the base of the child safety seat.

  • Patent number: 5138820
    Abstract: The substantially leak proof glazing system comprises a plurality of panels, each of which comprises a sheet of glass surrounded by a frame. The frame is formed of two angle members along each edge of the sheet which are slightly shorter than the edge of the sheet so that there is an open diagonal gap at the corner of the panel which leaves the corner open for receiving sealant. A resilient bezel is between each outer angle member and the outer surface of the corresponding sheet. The balance of the space between the edge of the sheet and the angle members is filled with a silicone sealant applied wet and cured in place. Channels in the faces of the bezel permit the detection of gas leakage through the seals. The glazing system has a generally U-shaped bond breaker covering a portion of the supporting structure. A quantity of silicone sealant is bonded between the edges of adjacent panels and the bond breaker, forming a substantially air tight seal between the panels.
