Abstract: The present invention relates to a vehicle frame assembly and methods of forming such assemblies as well as bracket for use in such assemblies. The assemblies include crossmembers arranged transversely and one or more rails extending longitudinally with respect to the crossmembers. Brackets are provided for connecting the crossmembers to the rail, and each bracket includes a first plate, a second plate and a connection section connecting the first plate to the second plate and bridging an area between the first and second plates. The first plates and the second plates of the brackets are configured to engage and be secured to either a surface of the at least one rail or a surface of the plurality of crossmembers. The brackets are configures so that when the first plates are secured to the surface of a rail, the second plates are secured to the surface of a crossmember and when the first plates are secured to the surface of a crossmember, the second plates are secured to the surface of a rail.

Abstract: A chair having a frame with one of a seat component and a backrest component, the seat component having a base member and a seat member while the backrest component include a base member and a backrest member where one of the seat and backrest component base member is connected to the frame. Complementary clip means on the one of the seat and backrest component base member allow the member to cooperate with the or each respective one of seat and backrest member, whereby either the respective seat member or backrest member can be clipped to the seat or backrest component base member. A toggle joint provides a snap over type connection effective when the one of the seat and backrest component base member and the one of the respective seat and backrest member are clipped together to cause one of the base member and the seat/backrest member to be in tension and the other member to be in compression when the two members of the component are clipped together.

Abstract: A retractable ramp system mounts a slideable ramp between lateral rail members which extend the length of a truck chassis and a container mounted thereon. The ramp is slideably suspended from a guide rail running parallel to the lateral rail members by means of a carriage component, itself slideably mounted within the guide rail. It is readily and easily extended and retracted by one person. When positioned directly on a truck chassis, the rail system is located above the hydraulic, electrical, and other mechanical systems positioned within the well of the truck chassis, such that the ramp is slideably moveable over these system components without interfering with them or any other part of the truck chassis. The ramp system is conveniently used for loading and off-loading containers which rest on the truck chassis or which are elevated above the chassis.

Abstract: A seating system is provided including a beam for supporting seats, wherein the seats are individually mounted to the beam at any selected longitudinal position along the beam. The system facilitates seat positioning and repositioning in a manner that optimizes seating adaptability and ease of installation. The beam preferably includes integral first and second track portions. The first track portion includes a channel that receives bracket-mounted connectors by which the beam is fixed relative to the ground. Each of the seats has at least one seat support with a clamp portion that secures to the second track portion of the beam, free from the channel to avoid interfering with the connectors, regardless of the point at which the support is clamped to the beam. The second track portion is preferably shaped to include a rear overhang and front overhang defining oppositely directed undercut surfaces on which the seat support is securely mounted.
