A lumbar support for a vehicle seat comprises two interlocking elements which can be moved into position between a seat back cushion and a seat frame and then interlocked, thus fixing the lumbar support relative the cushion and the frame. The elements can be permanently placed in functioning position without damage to, or alteration of, the seat, without using special tools, and while the seat remains in position in the vehicle.

A draft and depth control means comprises two divisible portions mounted on a base part and a detachable part of a housing, respectively, with the components of the portions remaining in position on separation of the parts. In the assembled condition the portions are coupled by non-fastening engaging surfaces readily separated on division of the portions. The portion on the detachable part comprises a hydraulic control valve and actuating bell cranks. The portion on the main part includes a cont...

A front wheel suspension for motorcycles including a pair of first linkages each having link members for interconnecting an upper fork pivotably supported on a motorcycle body and a lower fork supporting a front wheel thereon, and a pair of second linkages for restraining the deformation of the first linkages through a damper, the upper fork having a hollow formed therein in which at least a part of the second linkage is accommodated. The suspension has the moment of inertia relative to the hand...

A locking system for a tricycle, including a braking mechanism, a rolling restraint mechanism, a driving mechanism which drives the braking mechanism and the rolling restraint mechanism, a control mechanism for applying control signals, and a detecting mechanism for applying a speed signal to the driving mechanism when a vehicle speed is lower than a predetermined value. The driving mechanism selectively or simultaneously drives the braking and restraint mechanisms in response to the control sig...

A housing module which is formed as a box-beam structure, and has sufficient rigidity and strength so that it can be used to span distances of relatively great length. The housing unit is able to be prefabricated and can be readily transported without the need for additional support or stiffening members to prevent damage from excess flexure. Further, the unit can be simply put in place on site without any additional stiffening or strengthing members. In addition, the units can be stacked one ov...

In a vehicle provided with a turbine-type fuel flow meter for detecting the flow rate of fuel supplied to a carburetor of an internal combustion engine, a method for integrating the amount of fuel consumption which comprises the steps of summing the flow rate detected by the fuel flow meter at each prescribed time, comparing a quantity relating to the vehicle speed in a mean value at the prescribed time with a given reference value, selecting one from at least two prescribed correction factors b...

An encoding game device having a series of flexible elongated carriers including a series of compartments interconnected by reduced sections. Each compartment contains a rotatable sphere having raised binary 1's and 0's with different tactile backgrounds for visual and tactile sensing. The carriers are used in conjunction with registers for coding and decoding selected words using binary, phonetic and semantic codings.

A rear cover device in a motorcycle having an engine disposed substantially in front of a rear wheel, a muffler at one side of the rear wheel, and a rear wheel support member and a shock absorber at the other side of the rear wheel. The device comprises a cover member which covers the rear wheel from above and also covers portions of both sides of the rear wheel while accommodating the shock absorber therewithin, and a container member constructed integrally with the cover member and extending i...

An electrical connector device for use in an electrical system requiring electrical connection between rotatable members. The device comprises a first insulator having at least one first terminal affixed thereto, a first shaft member projecting from the first insulator, a second insulator rotatably fitted over the first shaft member and having at least one second terminal affixed thereto, a second shaft member secured to the second insulator, a flexible conductor in the form of a wire having eit...

A box for displaying and selling small articles such as Christmas ornaments and the like. The box includes a lower part having a side panel which forms a base for displaying the box in an upright position on one of its sides, and an opposite panel provided with a slit for receiving and supporting a hanging member of an article to be displayed in the box such that the article is suspended above the base panel in freely swinging relation thereto. The box further includes a lid having a window-like...
