Abstract: The automatic safety seat in a vehicle are designed to minimize the seriousness of car-crash injuries during a frontal collision. When the vehicle collides against other vehicle at a relative velocity of 40 Km/h or up, the backrest is pushed to recline backward by action of springs and various mechanisms designed. A tension spring is one of the most important part used to bring the backrest to a reclining position. Collision results in pulling the upper part of occupants fastened by designed safety-belts to the backrest to recline backwards to the rearmost. Thus, pelvis, chest and head of the occupant are moved away to the farmost and can avoid striking with deforming frontal parts of the intruding car by frontal collision. Chest injuries and brain damage can be avoided.
Abstract: Endless loops spaced lengthwise of elongated grouser-mounting plates of a tractor endless tread in which each loop includes two side-by-side stretches of wire rope having the interstices between the strands of both wire rope stretches filled with elastomer material, and both stretches of wire rope being embedded in elastomer material integrating the two stretches into a single embedment, the two wire rope loops being secured to the grouser-mounting plates by spaced U-shaped bends of clamping strips bolted to the grouser-mounting plates, and spacer plates bridge between adjacent grouser-mounting plates and make loose tongue-and-groove joints therewith for enabling the grouser-mounting plates and the spacer plates to tilt relatively as the endless tread travels around a tractor wheel, but the straight tread portion of the tread extending between tractor wheels spaced lengthwise of the tractor is substantially inflexible inward.
Abstract: A hydraulic chain tensioning means for automatically tensioning the chains of crawler vehicles equipped with two-, four- or eight-wheel articulated suspension means comprises essentially two tensioning cylinders (1.1 and 1.2) and a plurality of valves (3). The two tensioning cylinders (1.1 and 1.2) are interconnected by way of ducts (4) and connected by further ducts (5) to the valves (3). The tensioning cylinders (1.1 and 1.2) are fitted to the chassis (10) of the crawler vehicle and the leading wheel of the crawler vehicle bears against the piston rods (1.1K and 1.2K) of the tensioning cylinders (1.1 and 1.2). Parallel to the tensioning cylinders (1.1 and 1.2) a soft spring (piston-type accumulator 6) is connected so that at the beginning of the chain tensioning means being put under load only a minor pressure rise occurs in the tensioning cylinders (1.1 and 1.2).
Abstract: A container, such as a transfer trailer, a roll-off container, or other container that can be transported, has expandable side walls. The walls are hydraulically, or otherwise, forced outward to increase the inside width dimension of the container. A loading device, such as a garbage route collection truck or other similar vehicle can then be backed into the container whereby the solid material waste or other commodities can be directly loaded into the container. Once the container has been loaded, the side walls can be retracted to their original positions, such that the container maintains its standard regulated width dimension.

Abstract: In the structure of a vehicle, torque boxes are provided for coupling extension sideframes and sidesills on right and left sides in the front of the vehicle cabin. The rear end portions of the suspension member are coupled to rear coupling portions provided in the torque boxes, and coupling points for coupling thereat with the suspension member of the rear coupling portions are provided outside in a widthwise direction of the vehicle relative to the center of a section of the extension sideframes, and inside in the car width direction than the center of a section of the sidesills. With this structure, a load to the rearward of the vehicle of the suspension member at the time of a front-end collision and a front-end offset collision of the vehicle can be efficiently dissipated and transmitted to the extension sideframe and the sidesill via the torque box, and any retreat of the suspension member can be suppressed with a light and simple structure.
Abstract: An auxiliary sun visor formed of a transparent polarized shield is removably attached to conventional vehicle sun visor in a manner allowing it to be pivoted without simultaneous movement of the conventional sun visor.
Abstract: A tank cap which is pivotally supported, preferably about an approximately vertical axis, at an end portion of a tank inlet tray of an automotive vehicle, a carrier element of plastic material being provided having an outer circumference approximately corresponding to that of the tank cap and being pivotally supported by the inlet tray, and a cover element of sheet metal being attached to the outer surface of the carrier element.
Abstract: A removable rear seat for motor vehicles, in particular for Estate cars with a variable-volume loading space, having a rigid seat bench and a seat-bench substructure for fixing the seat height. The substructure is fixed on the floor of the vehicle body via releasable anchorage locations. In order to provide a rear seat which is manageable, easy to remove, and makes optimum use of the resulting free space after the rear seat has been removed, the seat-bench substructure is connected releasably, at its end remote from the anchorage locations, to the seat bench and is retained in its anchorage location. Thus, it can be pivoted out of a use position into a stowage position on or in the floor of the vehicle body and vice versa. At least one manually actuatable locking device locks the seat-bench substructure in its use position and determines the seat height.

Abstract: A hub for greasing inner and outer shaft bearings on a spindle having greasing passageways leading in from the front of the hub. One passageway leads to the front of the outer bearing and the other passageway leads to the rear of the inner bearing. A purging passageway is provided between the inner and outer bearings whereby upon pressured grease being forced into greasing passageways in the direction of the purging passageways, new grease is forced in an axial direction through the bearings and old grease and contaminants are purged. An annular seal between the bearings provides the purging passageway with the spindle, such passageway being next to the shaft for maintaining a supply of grease on the shaft. The seal has at least one annular recess for providing additional storage of grease. Grease holding areas are provided adjacent the bearings such that grease is forced into the bearings by centrifugal force when the hub rotates on the spindle.
