Abstract: A combined vent and escape hatch assembly for a vehicle roof of the type wherein the hatch is supported upon a pair of over-center hinge linkage devices one of which may be disconnected enabling the hatch to be fully opened for emergency exit purposes and wherein the other hinge device is protected against damage through the flexure of various hatch supporting components.

Abstract: A combined static and powered vent device for a vehicle such as a bus wherein the interior of the vehicle is continuously vented to the atmosphere in such a way that the forward movement of the bus causes an eductive drawing of the air from the vehicle interior and which also includes a powered fan device for venting the vehicle interior when static or eductive venting is inadequate.

Abstract: The invention relates to a vehicle safety device wherein the device is pivotally mounted along the lower edge of the vehicle body such that the device may be stored beneath the body when the vehicle is moving and lowered through a pivoting action to block the space between the vehicle body and the ground and in being lowered tends to engage and sweep any object in its path from beneath the vehicle and outwardly of the vehicle wheels.

Abstract: The present invention relates to an extendible and retractable ramp device for a vehicle particularly concerned with the loading and unloading of a handicapped person and which device particularly includes a power actuating mechanism disposed within the vehicle in such a way as to both protect the mechanism from damage and further including a track mechanism for lifting one end of the ramp to the vehicle floor level when the ramp is in its extended position.

Abstract: The present invention relates to an extendible and retractable ramp device for a vehicle particularly concerned with the loading and unloading of handicapped person and which device particularly includes a power actuating mechanism disposed within the vehicle in such a way as to protect the mechanism from damage, provide a ramp structure conducive to non-interferring ingress and egress by handicapped passengers and to incorporate a disconnect device which permits the ramp to be extended or retracted manually in the event power actuating mechanism becomes inoperative.

Abstract: The bumper system of the present invention includes a beam member adapted to span the front of a vehicle, a bracket for mounting the beam to the vehicle, and a pair of energy absorbing members supported upon the beam on the side thereof opposite from the bracket, the improvement in which system comprises the beam having a generally C-shaped cross section which includes a vertical wall portion, a pair of horizontal leg portions which project forwardly from the upper and lower edges of the vertical wall portion and each leg portion respectively terminating in an inwardly extending lip whereby said leg and lip portions respectively coact with the vertical wall to define upper and lower inwardly opening channels; each energy absorbing member comprising a hollow, rigidified and deflectable structural element which is supported upon the beam such that the major portion of the structural element projects forwardly of the beam, the structural element including: a first portion disposed forwardly of the beam; a second

Abstract: The bumper system of the present invention is of a modular design wherein two substantially identical, laterally extending members are secured at the laterally innermost ends to define an integrated bumper device and wherein each module is formed of three preformed and structurally self-supporting elements adapted to be nested together and adhesively secured to form an integrated module including an elastomeric outer shell open at its rear most face, an energy absorbing hollow core element formed of a relatively rigid, though deflectable, high strength plastic material adapted to nest within the outer shell in abutting relationship with the relatively stiff transverse support beam adapted to abut against the hollow core element and enclose the open rear face of the outer shell and which beam and hollow core element have coacting faces formed to resist relative impact-induced movement therebetween.

Abstract: The bumper system of the present invention is of a modular design wherein two substantially identical, laterally extending members are secured at their laterally innermost ends to define an integrated bumper device and wherein each module includes an energy absorbing hollow core element formed of a relatively rigid, though deflectable, high strength plastic material mounted in front of and upon a relatively stiff transverse support beam member which is, in turn, adapted to be secured to a vehicle frame through a suitable rearwardly extending bracket structure and which energy absorbing element and support beam are encapsulated in an elastomeric outer skin layer.

Abstract: A static vent for a vehicle such as a bus wherein the interior of the vehicle is continuously vented to the atmosphere in such a way as to prevent the ingress of rain water to the vehicle compartment.

Abstract: The bumper system of the present invention is of a modular design wherein two substantially identical laterally extending members are secured at their laterally innermost ends to define an integrated bumper device and wherein each module includes a relatively soft and resilient material mounted in front of and upon a relatively stiff, though deflectable, transverse support beam member which is, in turn, adapted to be secured to a vehicle frame through a suitable rearwardly extending bracket structure.

Abstract: A vehicle escape or ventilating hatch mounting assembly includes a mounting ring to be received in the hatch opening of the vehicle and to which the hatch is directly releasably connected with a trim bezel extending within the hatch opening and cooperating with the ring to finish off the opening.

Abstract: A lid for a vehicle roof opening has linkage hinging it to the roof structure accommodating tilting the lid upwardly in either of two directions, or elevating it bodily, for use of the opening to ventilate the vehicle, including provision for manually actuatable means both internal and external of the vehicle for separating parts of the hinging linkage to permit swinging the lid fully open for use of the roof opening as an escape hatch. In a modification, the lid is hinged for tilting in only one direction to a ventilating position or swinging to the full open position in the same direction.

Abstract: A lid for a vehicle roof opening including a linkage hinging it to the roof structure to accommodate tilting of the lid upwardly in either of two directions, or elevating it bodily, for use of the opening to ventilate the vehicle and including provision for separating the linkage from the roof supporting structure to permit swinging the lid to a fully open position relative to the roof opening to provide an escape hatch.
